To … Another way to include groups of tests is to aggregate multiple test classes. Technologies used in following examples : Junit 5.5.2; Maven 3; Java 8; Spring Tool Suite 3.9.8; 1. Resources JUnit 5 is pretty impressive, particularly when you look under the covers, at the extension model and the architecture.But on the surface, where tests are written, the development is more evolutionary than revolutionary - are there no killer features over JUnit 4? This might not seem like worth mentioning but, from my point of view, this is great. After each test case, Mockito extension validates the framework state to detect invalid use of Mockito. This annotation is used to disable the test class or method. With the new annotation, you can tag classes or methods. The canonical reference for building a production grade API with Spring. assertAll() method belongs to JUnit 5 org.junit.jupiter.api.Assertions Class. If we want to run tests which use JUnit 4 or 3, we have to add the junit-vintage-engine dependency (version 5.4.2) to the testRuntime dependency configuration. As mentioned earlier, you can now use lambdas in assertions: Although the example above is trivial, one advantage of using the lambda expression for the assertion message is that it is lazily evaluated, which can save time and resources if the message construction is expensive. In case you want to run a test for a specific class or multiple cases, use this annotation: After executing the example above, only tests in class "WeatherServiceTest" were run. To show you both annotations in action, this is the project structure that I’m going to use: After executing the example above, only tests in package “calculator” were run. This is typically used for external conditions that are required for the test to run properly, but which are not directly related to whatever is being tested. In this article, we will learn how to use assertAll method to group different assertions. Due to the design, these tests are usually very quick so they can be run very often.
