JUnit 5 aims to adapt java 8 style of coding and to be more robust and flexible than JUnit 4. In this post, JUnit 5 vs JUnit 4, we will focus on some major differences between them.
Eclipse has great tooling support for JUnit test cases. Having code templates for JUnit test cases configured in Eclipse is a great addition in faster test development. Learn to create and import JUnit 5 test templates in eclipse.
In JUnit 5, to test exception cases you should use org.junit.jupiter.api.Assertions.assertThrows() method. There are other ways for junit 5 exception testing, but I will suggest to avoid them. Syntax of Assertions.assertThrows() It asserts that execution of the supplied executable throws an exception of the expectedType and returns the exception. public static <T extends Throwable> T […]
JUnit @Disabled annotation can be used to disable the test methods from test suite. This annotation can be applied over a test class as well as over individual test methods.
JUnit 5 Assumptions class provides static methods to support conditional test execution based on assumptions. A failed assumption results in a test being aborted. Assumptions are typically used whenever it does not make sense to continue execution of a given test method. In test report, these test will be marked as passed.
JUnit 5 assertions help in validating the expected output with actual output of a testcase. To keep things simple, all JUnit Jupiter assertions are static methods in the org.junit.jupiter.Assertions class.
In JUnit 5, test lifecycle is driven by 4 primary annotations i.e. @BeforeAll, @BeforeEach, @AfterEach and @AfterAll. Along with it, each test method must be marked with @Test annotation. @Test annotation is virtually unchanged, although it no longer takes optional arguments.
Learn to configure junit 5 with gradle, its juniper and platform modules and how to use them to create and execute tests.
Learn to configure junit 5 with maven, its jupiter and platform different modules and how to use them to create and execute tests.
JUnit 5 @Tag can be used to filter testcases from test plans. It can help in create multiple different test plans for different environments, different use-cases or any specific requirement. You can execute set of tests by including only those tagged tests in test plan OR by excluding other tests from test plan.
