The @Disabled annotation in JUnit is used to indicate that a test class or test method should not be executed. This guide covers the basics of using the @Disabled annotation to temporarily disable tests in JUnit.
The @AfterAll annotation in JUnit is used to specify methods that should be run once after all test methods in the class. This guide covers the basics of using the @AfterAll annotation to clean up shared resources in JUnit.
The @BeforeAll annotation in JUnit is used to specify methods that should be run once before all test methods in the class. This guide covers the basics of using the @BeforeAll annotation to set up shared resources in JUnit.
The @AfterEach annotation in JUnit is used to specify methods that should be run after each test method. This guide covers the basics of using the @AfterEach annotation to clean up the test environment in JUnit.

Introduction JUnit provides an easy way to write and execute unit tests for Java applications. The @Test annotation marks methods to be executed as tests. This makes it simple to write tests for methods and classes, helping to ensure code quality and correctness. Key Points: Test Method Identification: The @Test annotation marks a method as …
Introduction In this chapter, we will explore how to use temporary directories in JUnit. Temporary directories are useful for tests that require file system operations without leaving any artifacts behind. JUnit 5 provides the @TempDir annotation to create and manage temporary directories and files that are automatically cleaned up after the test execution. What are …
Introduction In this chapter, we will explore how to run tests in parallel using JUnit. Parallel test execution can significantly reduce the overall time required to run a large test suite, especially on multi-core processors. JUnit 5 provides built-in support for parallel test execution, allowing you to configure and manage how tests are executed concurrently. …
Introduction In this chapter, we will explore JUnit timeouts. Timeouts are useful for ensuring that tests complete within a specified time limit. This is particularly important for performance testing, preventing long-running tests from causing delays in the test suite execution, and detecting potential infinite loops or deadlocks. What are Timeouts? Timeouts in JUnit allow you …
Introduction In this chapter, we will explore JUnit dynamic tests. Dynamic tests allow you to create and execute tests programmatically at runtime. This is useful when the number of tests or their inputs are not known until execution time, providing flexibility and power in your testing strategy. What are Dynamic Tests? Dynamic tests in JUnit …
Introduction In this chapter, we will explore JUnit test templates. Test templates are useful for creating reusable test structures that can be customized for different test scenarios. This helps in avoiding duplication and makes your test code more maintainable. What are Test Templates? Test templates in JUnit allow you to define a base structure for …
Introduction In this chapter, we will explore how to control the execution order of tests in JUnit. By default, JUnit executes tests in an unpredictable order, which is often desirable to ensure that tests are independent of each other. However, there are scenarios where controlling the execution order is useful, such as when tests depend …
Introduction In this chapter, we will explore how to use tagging and filtering in JUnit. Tagging allows you to categorize tests, and filtering enables you to run specific categories of tests based on tags. This can be particularly useful in large projects where you want to run subsets of tests, such as unit tests, integration …
Introduction In this chapter, we will explore JUnit assumptions. Assumptions are conditions that must be met for a test to proceed. If an assumption fails, the test is aborted and marked as skipped. This is useful for tests that should only run under specific conditions, such as certain environments or configurations. What are Assumptions? Assumptions …
Introduction In this chapter, we will explore how to execute repeated tests in JUnit. Repeated tests are useful when you want to run the same test multiple times to ensure consistent behavior or to simulate conditions that require multiple executions. JUnit provides the @RepeatedTest annotation to achieve this functionality. What are Repeated Tests? Repeated tests …
Introduction In this chapter, we will explore how to display custom test names in JUnit. Displaying meaningful test names can make test results more readable and understandable, especially when running a large suite of tests. JUnit provides annotations to customize the names of test methods and parameterized test cases. Customizing Test Names JUnit allows you …
Introduction In this chapter, we will explore how to disable tests in JUnit. Disabling tests are useful when you want to temporarily prevent certain tests from running without deleting or modifying the test code. JUnit provides annotations to achieve this functionality. What is Disabling Tests? Disabling tests allows you to prevent specific test methods or …
Introduction In this chapter, we will explore JUnit nested tests. Nested tests allow you to logically group test classes within a single test class. This is useful for organizing tests that share a common context or setup, making your test suite easier to maintain and understand. What are Nested Tests? Nested tests are a way …
