Don't Be Mocked by your Mocks - Best Practices using Mocks
0 likes732 views
Do you ❤️ Mocks? When you write your first unit tests, especially on older codebases, mocking foreign code is key to survival. But as you grow older in the craft, you start piling up hours and days wasted to refactor fragile tests or to fix bugs that those heavy mock-based tests didn't catch. And so you start looking at Mocks differently. Let's go through the key factors to consider to strike the optimal balance between what needs to be mocked away and what code should be tested in integration. There's sometimes a fine line there, often interwoven with strong emotions: "Why am I testing this?" "Argh… these tests take too long" "Can this ever really break?" etc... Among the points that we'll touch on: - Mocks vs Refactoring - Mocks vs Reliability - Fine vs Coarse Mocks - Reproducibility - Partial Mocks - Mocking Statics - Alternatives to Mocks Speakers: Victor Rentea Victor is a Java Champion and Independent Trainer with an impressive experience: thousands of developers in dozens of companies trained in dedicated company sessions. He is the founder of one of the largest developer communities in Romania, Bucharest Software Craftsmanship Community and a top international conference speaker.

Clean Pragmatic Architecture - Avoiding a Monolith
Clean Pragmatic Architecture - Avoiding a MonolithVictor Rentea Talk built based on several of my trainings: http://www.victorrentea.ro/#training
Covers: Clean/Onion/Hexagonal Architecture, Domain Entities, Value Objects, Repository, Extract When it Grows Principle, Dependency Inversion Principle, Clean Code and Design Patterns.
These are the backing slides of the talks given at JPoint 2017 and Devoxx PL 2017: https://www.youtube.com/embed/4-4ahz7zDiQ
The Art of Unit Testing - Towards a Testable Design
The Art of Unit Testing - Towards a Testable DesignVictor Rentea Slides of the Talk I gave at Devoxx Belgium 2019.
=== Abstract ===
Focusing on the creative work without being terrified of breaking the existing behavior can make software development very addictive! Good automated tests can buy you that!
However, if your tests are not maintainable they may end up slowing you down and causing you painful headaches, compilation errors and spurious failures. To avoid that, your unit tests should be significant; expressive; clean; DRY; non-overlapping; and blazing fast. Writing good tests becomes the toughest challenge for any developer, no matter how battle-hardened: you need to balance risk with test maintenance costs, while looking out for test design smells that call for [risky] refactoring to drive your design towards a set of key principles (included:).
Principles that will end up shaping the way you craft the Production code itself. Because in the end, a good, clean design is more important than coverage%.
But testing gives you the best feedback to get there.
Grab a black coffee and join this snippet from Victor’s Pro Unit Testing #training, to learn about testing priorities, buggy tests, the shared @Before, Mocks vs Stubs and how to reduce them by "purifying" your logic, testing Legacy Code and refactoring @Spy-es out.
All of that in an entertaining, dynamic and memorable session.
Clean pragmatic architecture @ devflix
Clean pragmatic architecture @ devflixVictor Rentea Victor Rentea introduces himself as a Java Champion, trainer, and speaker who focuses on topics like Hibernate, Spring, Java 8/FP, architecture, clean code, unit testing, reactive programming, and Java performance. He advocates building a deep, rich domain model with value objects and entities that encapsulate logic and enforce invariants. The document provides guidance on applying principles like separating concerns with layers, dependency inversion, and avoiding anemic domain models in order to build flexible, testable systems that are decoupled from frameworks and external dependencies.
Unit Testing like a Pro - The Circle of Purity
Unit Testing like a Pro - The Circle of PurityVictor Rentea Best practices on designing unit tests, designing testable production code, a glimpse of TDD, using mocks and isolating pure functions for easy testing. Talk distilled from http://victorrentea.ro/#unit-testing
Held at VoxxedDays Bucharest in March 2019.
Integration testing with spring @snow one
Integration testing with spring @snow oneVictor Rentea This document provides an overview of integration testing strategies and techniques. It discusses the differences between unit tests and integration tests, including that integration tests involve multiple layers and dependencies like databases, files, and web services, making them slower and more fragile. It also covers best practices for integration tests such as using an in-memory database, WireMock for stubbing external services, transaction management, and strategies for cleaning up after tests.
The tests are trying to tell you [email protected]
The tests are trying to tell you [email protected]Victor Rentea If tests are hard to write, the production design is crappy - goes an old saying. Indeed, writing unit tests gives you one of the most comprehensive, yet brutal, feedback about the design of your production code, but if it comes too late, many developers can’t stand it anymore and they will either stop testing or test more superficially. At the other extreme, others struggle to write contrived, fragile tests full of mocks that end up frustrating more than helping them. This talk reviews the main hints that unit tests provide you, from the most obvious improvements to some of the most subtle design principles.
Clean Lambdas & Streams in Java8
Clean Lambdas & Streams in Java8Victor Rentea Are you using Java8 Lambdas & Streams in your core business logic? Then you might be having this strange feeling that it’s not Java anymore: at times it’s cryptic, barely readable.. This was the topic of the workshop with the same name that I held at VoxxedDays Bucharest 2017. These are the slides backing the that workshop.
As a summary, the materials walk through the functional features of Java8, adding details along the way about how we can keep the code clean as we embrace the Java 8 features.
The entire desktop screencast + voice it's on youtube, here: https://youtu.be/uH9A37k2QkU

Evolving a Clean, Pragmatic Architecture - A Craftsman's Guide
Evolving a Clean, Pragmatic Architecture - A Craftsman's GuideVictor Rentea This document outlines an agenda and presentation on clean code architecture. It discusses modeling data with entities and value objects, organizing logic by extracting services and applying the onion architecture. It emphasizes testing to reduce fear, and protecting developers through simplicity and avoiding overengineering. The presentation emphasizes keeping data transfer objects lightweight and external to the domain.
The Art of Clean code
The Art of Clean codeVictor Rentea Slides of the talk held at JEEConf, Kiev and jPrime, Sofia. A personal view on the classic topics from the Uncle Bob's Clean Code bible, with some personal additions and tips&tricks. This topic actually represents the core of the training sessions that I provide as an independent trainer (www.victorrentea.ro)
Clean architecture - Protecting the Domain
Clean architecture - Protecting the DomainVictor Rentea The goal of architecture is to simplify the most complex parts of your logic. Any other goal should be secondary to this. The problem is that you can’t always anticipate where the complexity of your application will accumulate, especially when confronted with ever-changing requirements. The only way to keep your code simple is to gradually evolve the architecture without adding useless complexity up front, but always looking out for opportunities to break-down and refactor towards the most simple design that solves the problem. Drawing concepts from the Domain-Driven Development mindset, this talk summarizes the most important lessons learned designing and consulting many real-world projects. Along the way, you’ll hear about Value Objects and Entities, DTOs, Dependency Inversion Principle, Facades, the Onion Architecture and many pragmatic tips and tricks immediately applicable to your day-to-day work.

Extreme Professionalism - Software Craftsmanship
Extreme Professionalism - Software CraftsmanshipVictor Rentea Decades ago, IT started as a single engineering practice, but as time passed by it got increasingly fragmented. Conflicts broke out between testers vs developers vs sysadmins vs DBAs vs many other roles. Recently, developers themselves split into many subspecialties like backend/frontend/iOS/Android/microservices/functions/etc. The overspecialization we face today causes huge communication overhead, a low bus factor, lack of responsibility, blaming, repeated isolated patching and fulminating costs. The software craftsmanship movement is rising in this post-agile world with professionals eager to take control of their careers and continuously learn in the pursuit of mastery. This talk will show you practical ways in which to seed a continuous learning culture in your team or company, and foster the enthusiasm of your developers.
Clean Code - The Next Chapter
Clean Code - The Next ChapterVictor Rentea The document discusses clean code principles such as naming conventions, small functions, avoiding nulls and side effects, and using classes as containers for logic. It also emphasizes writing code for readability through techniques like extracting methods, renaming variables for clarity, and using comments to explain intentions rather than restate code. The presenter advocates for clean code as a way to improve code quality and maintainability over time.

Unit testing best practices
Unit testing best practicesnickokiss The document discusses best practices for unit testing, including:
1. Tests should follow a 3 step structure of prepare input, call method, check output. They should be fast, consistent, atomic, and have single responsibility.
2. Tests should isolate the environment, classes, and test instances to avoid dependencies. Mocking is recommended for environment isolation.
3. The best practices aim to make tests independent, fast, and easy to maintain through techniques like mocking and separating test logic from production code.

Unit testing - 9 design hints
Unit testing - 9 design hintsVictor Rentea Tests are hard to write if the production design is crappy - goes an old saying. Indeed, writing unit tests gives you one of the most comprehensive, yet brutal, feedback about the design of your production code, but if it comes too late, many developers can’t take it and they will either stop testing or test superficially. At the other end, others struggle to write contrieved, fragile tests full of mocks that end up frustrating more than helping them. This talk reviews the main hints that unit tests provide you, from the most obvious improvements to some of the most subtle design principles.

Harton-Presentation
Harton-PresentationHeather Harton The document discusses the author's thesis that it is possible to generate provable verification conditions for full behavioral verification of object-based software in a modular fashion. Key points:
- The author uses the RESOLVE specification and implementation language for verification.
- The verification system architecture includes a VC generator, proof checker, automated prover, and annotated code.
- The system aims to provide modular verification by verifying components one at a time using only specifications of reused components.
- The author has done research into mechanizing proof rules for constructs in modern languages to support automated verification.
Rise of the Machines - Automate your Development
Rise of the Machines - Automate your DevelopmentSven Peters When we talk about automation in software development, we immediately think of automated builds and deployments. We may also be using scripts to help make our daily work easier. But this is really just the beginning of the rise of the machines.
I show you how leading developers in our industry are using open source and commercial tools for automating much more. They've got "robots" for monitoring production servers, updating issues, supporting customers, reviewing code, setting up laptops, doing development reporting, conducting customer feedback -- even automating daily standups. In what instances is it useful to automate? In what cases does it not make sense? Automation prevents us from having to do the same thing twice, helps us to work better together, reduces workflow errors and frees up time to write production code.

Test Smarter Not Harder - how to design tests for continuous delivery
Test Smarter Not Harder - how to design tests for continuous deliveryMelissa Benua Imagine: as soon as any developed functionality is submitted into the code repository, it is automatically subjected to the appropriate battery of tests and then released straight into the wild. Setting up the pipeline to do just that has become commonplace, but most organizations hit the same stumbling block: just what IS the appropriate battery of tests? Automated build pipelines don't always lend themselves well to the traditional stages of testing. In this hands-on tutorial, Melissa will introduce testers to the key principles of test case and test suite design that apply to organizations big and small to allow them to take full advantage of the pipeline's capabilities without introducing unnecessary bottlenecks. Testers will learn how to make highly reliable tests that run fast and preserve just enough information to let the team determine exactly what went wrong and how to reproduce the error locally. They will also explore how to reduce overlap while still maintaining adequate test coverage, about what test areas might be most beneficial to combine into a single suite, and what areas might benefit most from being completely broken out.

Test-Driven Development Introduction
Test-Driven Development IntroductionSamsung Electronics Test-driven development (TDD) involves writing unit tests before writing application code to satisfy the tests and ensure functionality. Unit tests are automated tests that are independent, fast, and repeatable. TDD promotes code testability, good programming practices like loose coupling and encapsulation. It can be challenging to test components at the "edge" of systems like user interfaces and web services due to dependencies, so mock objects are used to replace unpredictable dependencies and allow isolation in tests. While TDD has advantages, it also has challenges to set up and maintain additional classes needed for mocking.

The Joy of Testing - Deep Dive @ Devoxx Belgium 2024
The Joy of Testing - Deep Dive @ Devoxx Belgium 2024Victor Rentea We spend half of our coding time reading, writing or fixing tests. But who likes that? To quickly fix this chore, we often copy-cat older tests or write new ones without paying much attention to their quality. This deep-dive walks you through a variety of practical testing techniques and tricks you must have in your toolbox to write expressive tests with a higher signal/noise ratio. In the agenda: test structure & naming, mutation testing (vs AI-gen tests), ObjectMother, why never to use assertEquals, nested fixtures, parameterized use/abuse, Gherkin, plus a few surprises. All this through an entertaining and interactive session that puts the joy back into testing.
Finding Java's Hidden Performance Traps @ DevoxxUK 2024
Finding Java's Hidden Performance Traps @ DevoxxUK 2024Victor Rentea Tracing the root cause of a performance issue requires a lot of patience, experience, and focus. It’s so hard that we sometimes attempt to guess by trying out tentative fixes, but that usually results in frustration, messy code, and a considerable waste of time and money. This talk explains how to correctly zoom in on a performance bottleneck using three levels of profiling: distributed tracing, metrics, and method profiling. After we learn to read the JVM profiler output as a flame graph, we explore a series of bottlenecks typical for backend systems, like connection/thread pool starvation, invisible aspects, blocking code, hot CPU methods, lock contention, and Virtual Thread pinning, and we learn to trace them even if they occur in library code you are not familiar with. Attend this talk and prepare for the performance issues that will eventually hit any successful system.

Modular Monolith - a Practical Alternative to Microservices @ Devoxx UK 2024
Modular Monolith - a Practical Alternative to Microservices @ Devoxx UK 2024Victor Rentea The microservices honeymoon is over. When starting a new project or revamping a legacy monolith, teams started looking for alternatives to microservices. The Modular Monolith, or 'Modulith', is an architecture that reaps the benefits of (vertical) functional decoupling without the high costs associated with separate deployments. This talk will delve into the advantages and challenges of this progressive architecture, beginning with exploring the concept of a 'module', its internal structure, public API, and inter-module communication patterns. Supported by spring-modulith, the talk provides practical guidance on addressing the main challenges of a Modultith Architecture: finding and guarding module boundaries, data decoupling, and integration module-testing. You should not miss this talk if you are a software architect or tech lead seeking practical, scalable solutions.

Microservice Resilience Patterns @VoxxedCern'24
Microservice Resilience Patterns @VoxxedCern'24Victor Rentea The network is reliable, has zero latency, with infinite, free bandwidth... And then you wake up. The plan was to go to microservices to build those reliable, super-scalable systems you saw in the ad. But your systems only communicate over synchronous protocols and the team never had a serious discussion about timeouts, retries, circuit breakers, and bulkhead patterns. If that’s your crude reality, please attend this session!
Distributed Consistency.pdf
Distributed Consistency.pdfVictor Rentea One of the many challenges of a distributed architecture is preserving the consistency of data across different systems. During this one-hour presentation, we are going to explore a number of strategies for maintaining consistency, going from the most basic options up to an automated recovery mechanism using compensations and reservations - what’s commonly referred to as a “saga” pattern. Our journey will be based on a hypothetical food delivery application on which we will analyze various decisions and their tradeoffs. The discussion will stay at an abstract, architectural level for the most part, with only a few code examples.
In the agenda:
- Idempotency and Retries
- 2 Phase Commit
- Eventual Consistency
- Compensations
- Reservations
- The Saga Pattern
Testing Microservices @DevoxxBE 23.pdf
Testing Microservices @DevoxxBE 23.pdfVictor Rentea Testing strategies for modern software architectures are evolving. As we transition from monolithic structures to team-sized microservices with crisp APIs aligned to bounded contexts, we encounter more stable testing surfaces. This shift leads many high-performing teams to favor integration tests over fine-grained, brittle unit tests. These integration tests, which are closer to the functional requirements, prove more trustworthy and are more resilient to internal refactoring, though they may come with a higher cost. In a vivid and engaging style, this talk addresses the primary challenges of integration testing in the microservices era: cognitive overload, test isolation, and test execution speed. Join the testing revolution and discover how to enhance your team's testing efficiency and effectiveness.
From Web to Flux @DevoxxBE 2023.pptx
From Web to Flux @DevoxxBE 2023.pptxVictor Rentea Ready for a deep dive into the world's most challenging programming paradigm? Reactive programming can simplify asynchronous and event-driven applications, but without a strong understanding, it can lead to frustration, recurring patchwork, missed deadlines, and costly bugs.
In this intensive three-hour session, we'll transition a traditional Spring application to WebFlux, revealing patterns and aanti-patterns when working with repositories, REST APIs, queues, and legacy libraries. You'll gain a clear understanding of often overlooked but critical aspects like subscribe signal, errors, cancellation, and signal loss. As a bonus, we'll debate the future of Reactive vs Virtual Threads, production-ready in Java 21.
This session is crucial for developers already working with reactive programming or those intending to make the leap.
Test-Driven Design Insights@DevoxxBE 2023.pptx
Test-Driven Design Insights@DevoxxBE 2023.pptxVictor Rentea Testing is fundamental in software development. Quality gates demand high coverage levels, pull requests need sufficient tests, leading to teams spending considerable time writing and maintaining them. But are we using our tests to their full potential?
'If code is hard to test, the design can be improved'. Starting from this mantra, this deep-dive session unveils hints to simplify code, break-down complexity, and effectively use functional programming. We'll delve into topics like fixture creep, partial mocks, onion architecture, and pure functions, providing numerous best practices and practical tips for your testing.
Be warned: This session may significantly disrupt your work routine and will likely change how you see testing. Attend at your own risk.
Profiling your Java Application
Profiling your Java ApplicationVictor Rentea The biggest challenge in performance tuning is identifying the root cause of the bottleneck. Once you find it, the fix often becomes trivial. However, this detective work takes patience, skills, and effort, so we often attempt to guess the cause, by trying out tentative fixes. The result: messy code, waste of time and money, and frustration. During this talk you will learn how to correctly zoom in on the bottleneck using three levels of profiling: distributed tracing with Zipkin, metrics with Micrometer, and profiling with the Java Flight Recorder already built into your JVM. We’ll focus on the latter and learn how to read a flame graph to trace some common issues of backend systems like connection/thread pool starvation, time-consuming aspects, hot methods, and lock contention, even if these occur in library code you did not write.
OAuth in the Wild
OAuth in the WildVictor Rentea Slides for my presentation about OAuth, going in depth in the details of the Authorization Code Grant and PKCE, also describing several security threats to OAuth
Vertical Slicing Architectures
Vertical Slicing ArchitecturesVictor Rentea Throughout the years, the Concentric Architectures (Onion, Hexagonal, Clean-..) have grown into the undisputed leader among backend systems architectures. With the rise of Domain-Driven Design, keeping your Domain ring 'agnostic' to the outside world has become the norm today. But history proved that any 'norm' in software architectures will cause overengineering if applied without criticism.
After a brief recap of these architectures, their pitfalls, and weaknesses, we'll see two alternatives that segregate code not in 'layers' or 'rings' but in vertical slices: Feature Slicing and Modular Monolith.
[Feature Slicing](vertical Slice Architecture) (aka *UseCase) has its own pitfalls and weaknesses, that we'll briefly review. But this will just warm us up for the next style.
Modular Monolith (aka Modulith) is an architecture style that helped many companies break their legacy codebases, and smoothly move to microservices. Most of the techniques discussed here can also come handy when one single microservice grew big and needs to be broken down.
Even more, greenfield projects today opt for this architecture instead of microservices, to avoid paying the high cost of distributability. Imagine cohesive but decoupled modules living in the same code base & deployment, but on which different teams work in harmony, delivering more value much faster than an equivalent microservice ecosystem.🦄
On the agenda:
- patterns to break data structures
- how to protect Domains inside modules
- communication patterns between modules
- breaking cyclic dependencies
Refactoring blockers and code smells @jNation 2021
Refactoring blockers and code smells @jNation 2021Victor Rentea The only way to survive in a codebase is by refactoring continuously. We know that since the Extreme Programming days. But what stops us from doing so today? In this talk, Victor summarizes what he learned discussing Clean Code and Refactoring with hundreds of teams throughout the world. You'll find ideas to tackle a broad spectrum of factors: technical, cultural, psychological, emotional, social, and even political. Using these you might unlock the freedom to refactor for you and your colleagues.
After this roundtrip, the talk briefly overviews several of the most dangerous code smells in the projects today: God Class, Duplicated Code vs Divergent Code, Temporal Coupling, Middle Man, Speculative Generality, Mutable Long-Lived State, Comments, and more. For each of them we’ll discuss a typical workaround, plus several subtleties and variations.

Integration testing with spring @JAX Mainz
Integration testing with spring @JAX MainzVictor Rentea Our sleep is better with longer-scoped tests. Our life is brighter if we don’t rely heavily on fine-grained tests that break whenever we refactor even the smallest detail. I’m talking about tilting the balance towards more integration than unit testing. And for that, let’s look at the testing features offered by the most used Java Framework today. We’ll see how to write fake test implementations, how to mock an unwanted Spring bean, what a Transactional Test is, and if and how to test your web endpoints. Along the way, we’ll also see Flaky tests, and discuss best practices about integration testing – all in an entertaining live coding session.
Your takeaways from this talk will be a lot of good practices and techniques directly applicable to your day-to-day project.
The Proxy Fairy and the Magic of Spring @JAX Mainz 2021
The Proxy Fairy and the Magic of Spring @JAX Mainz 2021Victor Rentea You can only claim you know Spring if you fully understand the Proxy design pattern and how the framework uses it to do its magic. Join this live coding session to explore 6 ways of intercepting method calls that you can use to cast your own spells and dramatically simplify your codebase.
Grab a strong coffee and prepare yourself for a whirlwind of **live-coding**, interwoven with **deep theoretical concepts and implementation details** that you need to master if you are using the Spring Framework. We’ll start from a Decorator pattern implementation, proving 2 ways to wire it with Spring, then move to bare-hands interface proxies, concrete classes proxies, @Aspect applied to custom annotations, plus some standard off-the-shelf Spring aspects.
Join this talk and learn real-world best practices to use with Aspects, design hints, under-the-hood implementation details, debugging tips, and performance impact of aspects. All in an interactive, entertaining, and extremely dynamic session.

Proactive Vulnerability Detection in Source Code Using Graph Neural Networks:...Ranjan Baisak As software complexity grows, traditional static analysis tools struggle to detect vulnerabilities with both precision and context—often triggering high false positive rates and developer fatigue. This article explores how Graph Neural Networks (GNNs), when applied to source code representations like Abstract Syntax Trees (ASTs), Control Flow Graphs (CFGs), and Data Flow Graphs (DFGs), can revolutionize vulnerability detection. We break down how GNNs model code semantics more effectively than flat token sequences, and how techniques like attention mechanisms, hybrid graph construction, and feedback loops significantly reduce false positives. With insights from real-world datasets and recent research, this guide shows how to build more reliable, proactive, and interpretable vulnerability detection systems using GNNs.

TestMigrationsInPy: A Dataset of Test Migrations from Unittest to Pytest (MSR...Andre Hora Unittest and pytest are the most popular testing frameworks in Python. Overall, pytest provides some advantages, including simpler assertion, reuse of fixtures, and interoperability. Due to such benefits, multiple projects in the Python ecosystem have migrated from unittest to pytest. To facilitate the migration, pytest can also run unittest tests, thus, the migration can happen gradually over time. However, the migration can be timeconsuming and take a long time to conclude. In this context, projects would benefit from automated solutions to support the migration process. In this paper, we propose TestMigrationsInPy, a dataset of test migrations from unittest to pytest. TestMigrationsInPy contains 923 real-world migrations performed by developers. Future research proposing novel solutions to migrate frameworks in Python can rely on TestMigrationsInPy as a ground truth. Moreover, as TestMigrationsInPy includes information about the migration type (e.g., changes in assertions or fixtures), our dataset enables novel solutions to be verified effectively, for instance, from simpler assertion migrations to more complex fixture migrations. TestMigrationsInPy is publicly available at: https://github.com/altinoalvesjunior/TestMigrationsInPy.

Explaining GitHub Actions Failures with Large Language Models Challenges, In...ssuserb14185 GitHub Actions (GA) has become the de facto tool that developers use to automate software workflows, seamlessly building, testing, and deploying code. Yet when GA fails, it disrupts development, causing delays and driving up costs. Diagnosing failures becomes especially challenging because error logs are often long, complex and unstructured. Given these difficulties, this study explores the potential of large language models (LLMs) to generate correct, clear, concise, and actionable contextual descriptions (or summaries) for GA failures, focusing on developers’ perceptions of their feasibility and usefulness. Our results show that over 80% of developers rated LLM explanations positively in terms of correctness for simpler/small logs. Overall, our findings suggest that LLMs can feasibly assist developers in understanding common GA errors, thus, potentially reducing manual analysis. However, we also found that improved reasoning abilities are needed to support more complex CI/CD scenarios. For instance, less experienced developers tend to be more positive on the described context, while seasoned developers prefer concise summaries. Overall, our work offers key insights for researchers enhancing LLM reasoning, particularly in adapting explanations to user expertise.

Who Watches the Watchmen (SciFiDevCon 2025)
Who Watches the Watchmen (SciFiDevCon 2025)Allon Mureinik Tests, especially unit tests, are the developers’ superheroes. They allow us to mess around with our code and keep us safe.
We often trust them with the safety of our codebase, but how do we know that we should? How do we know that this trust is well-deserved?
Enter mutation testing – by intentionally injecting harmful mutations into our code and seeing if they are caught by the tests, we can evaluate the quality of the safety net they provide. By watching the watchmen, we can make sure our tests really protect us, and we aren’t just green-washing our IDEs to a false sense of security.
