Cucumber & gherkin language
Cucumber & gherkin languageselvanathankapilan Cucumber is a tool that allows software programmers to write automated tests for acceptance testing in a business-readable domain-specific language called Gherkin. Cucumber tests are written using a behavior-driven development (BDD) style with Given, When, Then steps. Cucumber supports testing applications developed in various programming languages and runs across different platforms and browsers.
Understanding Unit Testing
Understanding Unit Testingikhwanhayat Unit testing is a method to test individual units of source code to determine if they are fit for use. A unit is the smallest testable part of an application. Unit tests are created by programmers during development. Test-driven development uses tests to drive the design by writing a failing test first, then code to pass the test, and refactoring the code. Unit tests should be isolated, repeatable, fast, self-documenting, and use techniques like dependency injection and mocking dependencies. Benefits of unit testing include instant feedback, promoting modularity, acting as a safety net for changes, and providing documentation.
Data Driven Testing
Data Driven TestingMaveryx Data-driven testing is a methodology where test input and output values are read from external data sources like files or databases. A single test script can be used to execute multiple test cases by varying the test data. Maveryx is a tool that supports data-driven testing through features like intelligent object recognition, separation of test logic from data, and reading test data from sources like Excel. The document provides an overview of data-driven testing and examples of how to create a data-driven test script using Maveryx.

Mocking in Java with Mockito
Mocking in Java with MockitoRichard Paul Mockito is a mocking framework for Java that allows developers to focus tests on interactions between objects rather than states. It provides test doubles like mocks and spies to simulate dependencies and verify expected interactions. Mockito allows mocking method calls and configuring return values or exceptions to test different scenarios. It provides default values for unstubbed calls to avoid overspecifying tests.
Unit Testing in Java
Unit Testing in JavaAhmed M. Gomaa Unit testing involves writing code to test individual units or components of an application to ensure they operate as intended. A unit test targets a specific function or class and ensures the code works correctly. A test suite is a collection of test cases that test a module. Frameworks like JUnit simplify the unit testing process and allow for test automation. JUnit tests are created in the same project structure with a "Test" suffix and use annotations to define test cases and suites. Tests can then be run and results analyzed to measure code coverage.
An Introduction to JUnit 5 and how to use it with Spring boot tests and Mockito
An Introduction to JUnit 5 and how to use it with Spring boot tests and Mockitoshaunthomas999 This document provides an overview of JUnit 5, including its components and features. It introduces JUnit 5 as an improvement over JUnit 4, released in 2017 to work with Java 8+. JUnit 5 consists of the Platform, Jupiter, and Vintage. The Platform provides test discovery and execution. Jupiter supports writing new tests with annotations and extensions. Vintage allows running old JUnit 3 & 4 tests on the platform. New features discussed include assertions, assumptions, display names, tags, repetition, and parameterization. It also covers using JUnit 5 with Spring tests and Mockito.

For Mockito, the document discusses how to create and use mock objects to stub behavior and verify interactions. It provides examples of argument matchers and consecutive stubbing in Mockito.
Unit Tests And Automated Testing
Unit Tests And Automated TestingLee Englestone The document discusses unit testing and automated testing. It defines various testing terminology like unit tests, integration tests, system tests, and regression tests. It emphasizes the importance of testing early and often to find bugs quickly, increase quality assurance, and improve code design for testability. Automating tests through continuous integration is recommended to efficiently run tests on new code commits and catch errors early. Test-driven development is introduced as a practice of writing tests before code to ensure all tests initially fail and the code is developed to pass the tests.

Testing with Spring: An Introduction
Testing with Spring: An IntroductionSam Brannen The Spring Framework has always embraced testing as a first class citizen. Spring-based components should be modular, easy to wire together via dependency injection, and therefore easy to test. In fact, when well designed following a POJO programming model, a component in a Spring application can be unit tested without using Spring at all. And when you take the step toward developing integration tests, Spring's testing support is there to make your job easy.
Join Spring Test component lead Sam Brannen in this talk to learn about the basics for Spring's unit and integration testing support. This talk will provide attendees an overview of the following topics: unit testing without Spring, integration testing with Spring, loading application contexts (with and without context hierarchies), injecting dependencies into tests, transaction management for tests, SQL script execution, testing Spring MVC and REST web applications, and more.

clean code book summary - uncle bob - English version
clean code book summary - uncle bob - English versionsaber tabatabaee The document provides guidance on writing clean code based on the book "Clean Code" by Robert Cecil Martin. Some of the key points discussed include:
- Functions should do one thing and do it well, with a single level of abstraction and no side effects. They should fit on a screen.
- Names should be meaningful, avoid abbreviations, and use consistent vocabulary. Class names should be nouns and method names should be verbs.
- Code formatting is important for readability. Classes should not exceed 200 lines, functions a single screen. Variables should be declared near use.
- Comments should only explain why unusual decisions were made, not what the code does. Avoid commented out code or redundant comments

Difference between ActionResult() and ViewResult()
Difference between ActionResult() and ViewResult()Umar Ali ActionResult() is an abstract base class that defines the general result type for MVC actions. ViewResult() is a concrete subclass of ActionResult() that renders a specified view to the response stream. Some key subtypes of ActionResult() include ViewResult(), PartialViewResult(), EmptyResult(), RedirectResult(), and JsonResult(). ActionResult() allows for polymorphism and dynamic behavior by returning different result types from an action. It should be used as the return type when an action may have different behaviors, while ViewResult() can be used when an action will definitely return a view.
