Understanding the Lifecycle of a Test Case in JUnit 5

Testing is a crucial part of any software development process. In the Java world, JUnit 5 plays a key role in writing effective test cases. While testing is a non-functional requirement, understanding it is very important if you’re aiming to build robust applications. Whether you’re just starting out or already have experience, knowing how JUnit handles the lifecycle of test cases is essential for writing efficient and maintainable tests.

In this post, we’ll go through the lifecycle of a test case in JUnit 5, exploring the key annotations that represent the different stages of the test lifecycle. By the end, you’ll have a clearer understanding of lifecycle stages.

Introduction

JUnit 5 introduces a powerful and flexible mechanism to control the lifecycle of test execution. The framework defines specific phases for setting up, executing, and cleaning up…
