Hi all, Over the past couple of days I've merged a series of patches that upgrade the Engine's usage of JUnit to JUnit Jupiter 5.2 in order to make it easier to write new tests.
Despite the patches being quite straight-forward, since Jupiter is **not** backwards compatible to JUnit 4, or even JUnit 5 Vintage, here's the short version of what you need to know: 1. You no longer use annotations from the org.junit package, but the junit.org.jupiter.api packages. @Before and @After have been replaced with @BeforeEach and AfterEach respectively, and @BeforeClass and @AfterClass have been replaced with @BeforeAll and @AfterAll. 2. Assertions now live in the org.junit.jupiter.api.Assertions class. Note that the optional message parameter is now the **last** parameter in all the assertions, not the first. Also worth noting that assertThat has been removed. More often than not, assertTrue can be used with a Supplier<Boolean>, but if you absolutely need an assertThat method, just use the one that Hamcrest provides. 3. Similarly, assumptions live in org.junit.jupiter.api.Assumptions. 4. No more runners - extending tests in JUnit Jupiter is done with Extensions. There's no longer a need for the Parameterized and Theories runners, as you can just use the built-in @ParameterizedTest annotation. Instead of the MockitoJUnitRunner we used to heavily rely on, you should now use MockitoExtension. 5. No more Rules - these too were replaced with extensions. Our custom rules were replaced with extensions, which are pretty well documented both in their javadoc and in wiki under [1] For additional information, you could take a look at the official documentation [2] Happy testing!
