Article Introduction：The release of JUnit 5 simplifies integrating this library into projects since there is no need to migrate from JUnit 4. However, in a large project using both JUnit 5 and 4, this coexistence can cause confusion and maintenance difficulties. To solve this problem, this article recommends taking the following steps: informing teams about new features in JUnit 5, encouraging writing new tests using JUnit 5, and following the Scout rule when removing JUnit 4. Additionally, this article explores notable changes in JUnit 5, including updates to annotations, methods, and test configurations, as well as the new @ParameterizedTest annotation. Finally, the article emphasizes excluding dependencies, creating

Article Introduction：Basics of JUnit JUnit is an annotation-based framework that uses the @Test annotation to identify test methods to be executed. These methods must return no value and must not throw any checked exceptions. JUnit automatically runs all methods annotated with @Test and reports any failures or errors. Example: importorg.junit.Test;publicclassMyTestClass{@TestpublicvoidtestMethod(){//Writing test code}} Assertion JUnit provides a series of assertion methods that allow developers to verify test results. Commonly used assertions include: assertEquals(expe

Article Introduction：JUnit is a unit testing framework in Java used for testing individual methods or classes. Add JUnit dependencies: JUnit dependencies can be installed via Maven or Gradle. Create a test case: Mark a method with the @Test annotation and write the code to be tested. Assert results: Use assertEquals, assertTrue, assertFalse and other assertion methods to check the test results. Practical case: The sample test case shows how to test the function getFullName, which combines firstName and lastName into a complete name. Run tests: Use an IDE or command line tool to run JUnit tests.
