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.
JUnit 5 Test Templates for Eclipse
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.
JUnit 5 Expected Exception Test Example
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 5 @Disabled Test Example
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 Examples
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 Examples
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.
JUnit 5 Test LifeCycle
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.
JUnit 5 Gradle Dependency [build.gradle] Example
Learn to configure junit 5 with gradle, its juniper and platform modules and how to use them to create and execute tests.
JUnit 5 Maven Dependency [pom.xml] Example
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 Annotation Example
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.
JUnit 5 Test Suites Examples
Using JUnit 5 test suites, you can run tests spread into multiple test classes and different packages. JUnit 5 provides two annotations: @SelectPackages and @SelectClasses to create test suites. Additionally, you can use other annotations for filtering test packages, classes or even test methods. Table of Contents Project Structure for Test classes and Suite Create […]
JUnit 5 @RepeatedTest Annotation Example
JUnit 5 @RepeatedTest annotation enable to write repeatable test templates which could be run multiple times. The frequency can be configured as parameter to @RepeatedTest annotation.
JUnit 5 @AfterAll Annotation Example
JUnit 5 @AfterAll annotation is replacement of @AfterClass annotation in JUnit 4. The annotated method should be executed after all tests in test class.
JUnit 5 @AfterEach Annotation Example
JUnit 5 @AfterEach annotation is replacement of @After annotation in JUnit 4.The annotated method should be executed after each @Test method in test class.
JUnit 5 @BeforeEach Annotation Example
JUnit 5 @BeforeEach annotation is replacement of @Before annotation in JUnit 4. Annotated method should be executed before each @Test method in test class.
JUnit 5 @BeforeAll Annotation Example
JUnit 5 @BeforeAll annotation is replacement of @BeforeClass and is used to signal that annotated method should be executed before all tests in test class.
JUnit 5 – Execute Testcase in Eclipse
Learn to execute junit 5 testcases in eclipse IDE. Maven has been used to import dependencies in this junit 5 example. Junit 5 Maven Dependencies To be able to execute junit 5 tests in eclipse, you will need following dependencies. junit-platform-runner in test scope: location of the JUnitPlatform runner junit-jupiter-api in test scope: API for […]
