Testing is important for project quality and reliability. Unit tests check individual code units for correct functionality, are fast and independent. Behavior-driven development (BDD) applies business needs through scenarios defined in Gherkin. Test doubles replace code to independently test objects like dummies, fakes, stubs and mocks. Integration tests check connections between components while acceptance tests check overall project behavior from the user perspective, ensuring expected functionality but are slower and require more maintenance.

Testing 101: Three Rules for Testing at Ombu Labs 
Testing 101: Three Rules for Testing at Ombu Labs Ombu Labs, The Lean Software Boutique In this presentation we talk about three rules that we follow every week to deliver high quality code. We prefer to write tests in this order: Integration tests first, unit tests later.
We don't do TDD religiously but it is a good idea when you're facing a very complex problem.
Think about your code as a black box and think about all the possible inputs and outputs, all the possible paths that a user might take, all the possible ranges that the user may enter.
Don't test only the happy path, keep in mind the odd cases.
Test-Driven Development Reference Card
Test-Driven Development Reference CardSeapine Software This document discusses Test-Driven Development (TDD). It defines TDD as writing unit tests before writing any production code. TDD helps ensure code is consistently refactored for better design. The document outlines the TDD process of writing a test, seeing it fail, writing code to pass the test, then refactoring. It discusses using TDD with legacy code by refactoring code to be testable. Sample unit tests are provided to demonstrate testing default constructor values. Benefits of TDD include better code design, earlier defect detection, and fewer defects in production releases.
TDD
TDDDotan Patrich Test Driven Development (TDD) is an approach where test cases are written before functional code to think about how components should work. It follows the principles of Red-Green-Refactor, writing a test (Red), then the functional code to pass the test (Green), then refactoring the code. TDD leads to well-designed, loosely coupled code with full test coverage that is easy to maintain and refactor with confidence in changes. While it may initially take longer, TDD finds bugs earlier and reduces bugs by 45-90%, saving significant time versus fixing issues late in development.
Testing the untestable
Testing the untestableRoyKlein 1. The document discusses techniques for testing legacy production code that was not originally written with testability in mind. This includes unit testing, which allows verifying code works as expected in isolation, and writing tests before making changes to help preserve existing behavior.
2. Testing legacy code can be challenging as the code may have dependencies that are hard to isolate for testing purposes. Techniques to address this include extracting functions to new classes, replacing static dependencies with interfaces, and overriding classes to inject test dependencies.
3. While testing legacy code requires more initial work, it provides long-term benefits like reducing defects, empowering refactoring, and creating a safety net for future changes. The document provides a case study and
Code Review
Code ReviewLukas Rypl This document discusses code review practices. It defines code review as the systematic examination of source code to identify defects, improve code quality, and share knowledge. Code review should occur after implementation but before testing. Reviews are done by peers to benefit from different perspectives and to spread knowledge across the team. Tips for effective code reviews include choosing the right person, reviewing the right amount of code, building checklists, providing positive feedback, and accepting reviews constructively. Code reviews can find more bugs than testing alone and improve code quality and maintainability.
Code review
Code reviewdqpi Code review is a process where one developer reviews another developer's code changes before they are submitted. It helps catch defects, improves code quality, and accelerates learning. There are different types of code review processes, including formal reviews, over-the-shoulder reviews, email reviews, pair programming, and tool-assisted reviews. Many large companies have implemented code review policies to improve their software development processes.
Unit tests benefits
Unit tests benefitsKate Semizhon The document discusses different types of software tests including unit tests, integration tests, acceptance tests, load tests, and performance tests. It emphasizes the importance of unit tests for validating individual code modules and classes work as intended. Writing unit tests before coding allows developers to test complex scenarios quickly, ensure code quality and readability, and refactor code with confidence.

TDD- Test Driven Development
TDD- Test Driven DevelopmentLiza Antoun Test Driven Development (TDD) is a technique where tests are written before code to define desired functionality, with the cycle of writing a test, seeing it fail, then writing code to pass the test while refactoring code for quality. TDD ensures requirements are met, forces clean code principles like isolated and decoupled components, and leads to improved test coverage and faster debugging. For effective TDD, tests should be clean, self-documented, have single asserts, run fast, be independent, and have boolean outputs. While it may initially slow development time, TDD provides long term benefits.
Test Driven Development
Test Driven Developmentdcsunu Test-driven development (TDD) is a software development process that employs short cycles of writing a test, making it fail, then writing code to pass the test. This helps improve code design and reduces defects. Each new feature starts with writing a test case, then coding just enough to pass the test, and refactoring the code without changing external behavior. TDD produces test code documentation and allows reversible changes by starting over from the last stable state if new code causes errors.

TDD with Ruby
TDD with RubyIsmael G Marín C The document discusses Test-Driven Development (TDD) with Ruby. It notes that the primary goal of TDD is specification and design, not just validation, by thinking through requirements and design before writing code. The TDD cycle involves adding a test, running all tests to see the new one fail, writing code to pass the test, refactoring code, and repeating. There are two levels of TDD: acceptance TDD which writes a single acceptance test and just enough code to pass it; and developer TDD which writes a single unit test and code to pass that test.
Clean code: understanding Boundaries and Unit Tests
Clean code: understanding Boundaries and Unit Testsradin reth This document discusses principles of clean code and unit testing. It covers boundaries when using third-party code, such as writing learning tests to understand external APIs. Tests should be kept clean like production code so they remain maintainable as the code evolves. Tests that are readable, use the BUILD-OPERATE-CHECK pattern, and have one assertion per test help achieve this. The document also advocates writing tests before production code according to the Three Laws of TDD and principles of FAST tests.

The document outlines the TDD process with steps of writing a failing test, writing just enough code to pass the test, and refactoring code if needed. It notes benefits of TDD include code that is always backed by tests, decoupled design, and automatically having full test coverage and regression tests.
Beyond Unit Testing
Beyond Unit TestingSøren Lund This document discusses going beyond unit testing for web applications. It introduces several tools for testing different aspects of web applications, including Selenium IDE for browser-based testing, soapUI for web service testing, and JMeter for performance and load testing. These tools can be run from the command line as part of continuous integration with Jenkins. The document cites research that unit testing only detects an average of 25% of defects, while integration testing detects 45%, and code reviews have even higher effectiveness rates.

Documenting Code - Patterns and Anti-patterns - NLPW 2016Søren Lund How do we document code? A good solution is to create self-explanatory code; this somewhat eliminates the need to document the code. We still need some very basic documentation. Code comments are one form of documentation, that is often misused. This talk is about self-explanatory code, the documentation we need and code comment patterns and anti-patterns.
Code Quality
Code QualityFrançois Camus The document discusses the importance of code quality and maintaining clean code. It provides principles for writing clean code such as the Boy Scout Rule, DRY principle, and Single Responsibility Principle. Pair programming and code reviews are recommended practices for ensuring code quality. Unit testing using a test-driven development approach helps avoid bugs and allows flexibility. Measuring metrics like test coverage and implementing a coding standard can improve code quality.
Testing & continuous delivery
Testing & continuous deliveryNelson Melina This document discusses software development best practices including unit testing, integration testing, continuous integration, and continuous delivery. Unit testing isolates and tests individual code units to verify they work as intended. Benefits include finding problems early and allowing refactoring without fear of regressions. Limitations are that tests only check for certain errors and require additional test code. Common unit testing tools include JUnit and Mock objects which simulate objects for testing. Integration testing combines modules tested individually. Continuous integration runs automated tests and builds on every code change. Continuous delivery fully automates the software delivery process.
Improving the accuracy and reliability of data analysis code
Improving the accuracy and reliability of data analysis codeJohan Carlin 1) The document discusses improving the accuracy and reliability of data analysis code through testing and version control. It emphasizes that reliable code is well-documented, generalizable beyond specific datasets, and includes tests to verify functionality.
2) Common approaches to testing include null simulations to calculate error rates and parameter recovery tests to confirm models can learn known weights. Version control through Git or SVN provides a record of code states over time.
3) The document argues that testing makes sense for scientific computing given demands on accuracy and risks of errors influencing research. Tests can target hypotheses, analysis methods, and experiment scripts.

Agile Mumbai 2020 Conference | How to get the best ROI on Your Test Automati...AgileNetwork - Writing automated tests takes a significant amount of time and effort, often resulting in test code that is twice or three times the size of the actual code being tested. This occurs because tests are written in isolation and dependencies must be mocked.
- A better approach is to write tests that focus on behaviors and public interfaces rather than implementation details. Tests should not break when implementation details change, only when public behaviors change. This allows for easier refactoring of code without breaking tests.
- Rather than focusing solely on unit tests, more effort should be put into system level testing which typically finds twice as many bugs. Tests can also be improved by designing them more formally and moving assertions directly into the code being tested.

Test driven development
Test driven developmentnamkha87 Unit testing involves writing code to test individual units or components in isolation to determine if they are functioning as expected. Writing tests first, before production code (test-driven development or TDD) can lead to higher quality code, easier debugging, and increased confidence in changes. The TDD process involves writing a failing test, then code to pass the test, and refactoring code as needed. To apply TDD effectively, tests should focus on logical code, avoid duplications, and isolate dependencies to keep tests simple and maintainable. Both server-side and client-side code need testing, focusing on things like business rules, view models, repositories, and UI logic.

Unit Testing Full@Alex Borsuk The document discusses unit testing principles and purposes. It states that unit testing is used to prove that classes work properly in isolation, catch bugs early, enforce high-quality code, and make refactoring safer. Unit testing encourages modular and loosely coupled code. However, it does not replace integration or system testing and not all code can be unit tested. The document also provides examples of when code should be refactored before writing unit tests.

Test-Driven-Development.pptxdheeraj438799 Test Driven Development (TDD) is a software development practice that focuses on creating unit test cases before developing code. It involves 3 phases - creating precise tests, making minimal changes to fix failed tests, and refactoring passed tests. Popular frameworks that support TDD include Junit for Java, PyUnit for Python, and Rspec for Ruby. TDD fits into Agile development by providing constant feedback to avoid building unusable software and align with changing requirements.

Alexandru Bolboaca - Unit Testing from the TrenchesMozaic Works This document provides clarification and practical ideas around unit testing. It begins by defining a unit test and the typical Arrange, Act, Assert structure. It then clarifies when tests are written, who writes different types of tests, and characteristics of good tests. Five practical ideas are presented to address common situations like bugs due to untested code, slow/unpredictable tests, and lack of test automation. The overall message is that unit tests form the "immune system" of a product and can replace manual testing and debugging when used properly.

It begins by describing the different types of tests - unit, integration, and acceptance. It then discusses the debate around having more unit tests vs acceptance tests. The document argues that less acceptance tests and more unit tests leads to faster, higher quality code. The rest of the document outlines five rules for writing effective tests: 1) Write tests before coding, 2) Don't test everything, 3) Test only public APIs, 4) Don't create extra getters for testing, and 5) Listen to what your tests are telling you about your code quality and design.

Some key best practices discussed are writing tests before code, focusing tests on functionality rather than code structure, and establishing governance and training to ensure proper adoption of TDD.
Test Driven Development using QUnit
Test Driven Development using QUnitsatejsahu Test Driven Development (TDD) using the QUnit framework. TDD involves writing test cases before writing code to pass those tests. This ensures code quality and prevents regressions. QUnit is a JavaScript unit testing framework that allows writing test cases and making assertions. Practicing TDD with QUnit involves writing unit tests, running them, then writing code to pass the tests, and refactoring code as needed. TDD results in more maintainable, robust code and a documented test suite for new developers.

An Introduction to Unit TestingSahar Nofal Unit testing involves writing automated tests to test code. Automated tests are repeatable and help catch bugs before deploying code. The main benefits of unit testing are that it allows developers to test code frequently and in less time, catch bugs before deploying, deploy with confidence, reduce bugs in production, and refactor code with confidence.
There are different types of tests including unit tests, integration tests, and end-to-end tests. Unit tests isolate a unit of code without external dependencies and execute fast but provide less confidence. Integration tests involve external dependencies and provide more confidence but take longer. End-to-end tests drive the application through its UI and provide great confidence but are slow.
Good unit tests
Testing & should i do it
Testing & should i do itMartin Sykora Testing code is important to avoid bugs but many PhD students do not rigorously test their code. This document discusses why testing is important and provides tips for effective testing strategies. It recommends having a testing plan, using unit tests, and test-driven development. Automated testing helps ensure code works as intended before and after changes. Rigorous testing adds confidence and allows code to be reused with less risk.
Testing Times
Testing TimesDan Hardiker This document discusses the importance of testing code through various methods like unit tests, integration tests, and acceptance tests. It recommends that developers write tests for their code, run tests frequently during development and before each commit. It also advises measuring code coverage to identify parts of the code that are not adequately tested so those risks can be addressed. Regular testing provides confidence in the code, helps with collaboration, and ensures code quality.

The Gaussian Process Modeling Module in UQLab
The Gaussian Process Modeling Module in UQLabJournal of Soft Computing in Civil Engineering We introduce the Gaussian process (GP) modeling module developed within the UQLab software framework. The novel design of the GP-module aims at providing seamless integration of GP modeling into any uncertainty quantification workflow, as well as a standalone surrogate modeling tool. We first briefly present the key mathematical tools on the basis of GP modeling (a.k.a. Kriging), as well as the associated theoretical and computational framework. We then provide an extensive overview of the available features of the software and demonstrate its flexibility and user-friendliness. Finally, we showcase the usage and the performance of the software on several applications borrowed from different fields of engineering. These include a basic surrogate of a well-known analytical benchmark function; a hierarchical Kriging example applied to wind turbine aero-servo-elastic simulations and a more complex geotechnical example that requires a non-stationary, user-defined correlation function. The GP-module, like the rest of the scientific code that is shipped with UQLab, is open source (BSD license).

Process Parameter Optimization for Minimizing Springback in Cold Drawing Proc...
Process Parameter Optimization for Minimizing Springback in Cold Drawing Proc...Journal of Soft Computing in Civil Engineering In tube drawing process, a tube is pulled out through a die and a plug to reduce its diameter and thickness as per the requirement. Dimensional accuracy of cold drawn tubes plays a vital role in the further quality of end products and controlling rejection in manufacturing processes of these end products. Springback phenomenon is the elastic strain recovery after removal of forming loads, causes geometrical inaccuracies in drawn tubes. Further, this leads to difficulty in achieving close dimensional tolerances. In the present work springback of EN 8 D tube material is studied for various cold drawing parameters. The process parameters in this work include die semi-angle, land width and drawing speed. The experimentation is done using Taguchi’s L36 orthogonal array, and then optimization is done in data analysis software Minitab 17. The results of ANOVA shows that 15 degrees die semi-angle,5 mm land width and 6 m/min drawing speed yields least springback. Furthermore, optimization algorithms named Particle Swarm Optimization (PSO), Simulated Annealing (SA) and Genetic Algorithm (GA) are applied which shows that 15 degrees die semi-angle, 10 mm land width and 8 m/min drawing speed results in minimal springback with almost 10.5 % improvement. Finally, the results of experimentation are validated with Finite Element Analysis technique using ANSYS.
