junit5

In Maven projects, I have some existing tests relying on JUnit 4. I cannot migrate these tests in JUnit 5 for multiple reasons. Essentially, some tests depend on a library which uses JUnit 4 runner and code migration may take time. I would like all the same create new test classes with JUnit 5 that is now released and provides new interesting features. How to do that ? JUnit 5 provides a way out of the box . JUnit 5 = JUnit Platform + JUnit Jupiter + JUnit Vintage Each one is a distinct project and using all of them allows to compile and execute JUnit 4 and JUnit 5 tests in a same project.

I would like to use the @Tag available in JUnit 5 in order to easily filter my tests. I have found in this blog input from September 2016 that IntelliJ was not supporting @Tag . Not sure what the current status is though. Also, I am very new to using Maven but I have tried modifying the POM file in order to filter tests when executing mvn test in a command prompt. No luck. Here's the solution I found: changing the JUnit versions in the POM file from ... <junit.jupiter.version>5.0.0-M2</junit.jupiter.version> <junit.vintage.version>4.12.0-M2</junit.vintage.version> <junit.platform.version>1.0.0

JUnit4 has @FixMethodOrder annotation which allows to use alphabetical order of test methods execution. Is there analogous JUnit5 mechanism? Edit: JUnit 5.4 is officially released now, so no need to use snapshots anymore. This is now possible with JUnit 5.4. https://junit.org/junit5/docs/current/user-guide/#writing-tests-test-execution-order To control the order in which test methods are executed, annotate your test class or test interface with @TestMethodOrder and specify the desired MethodOrderer implementation. You can implement your own custom MethodOrderer or use one of the following

I am creating a modular build (using module-info.java) on GitHub , but when adding a module-info.java to the modules that I want modular, no tests can be executed... How can I achieve this? I am using the following versions: junit.jupiter version 5.3.0 (first take was also unsuccessful with version 5.2.0) maven-compiler-plugin version 3.8.0 (first take was also unsuccessful with version 3.7.0) maven-surefire-plugin version 2.22.0 (first take was also unsuccessful with version 2.21.0) A typical error from the failing tests looks like: java.lang.reflect.InaccessibleObjectException: Unable to

The problem Whenever I run my projects JUnit test (using JUnit 5 with Java 9 and Eclipse Oxygen 1.a) I encounter the problem that eclipse can't find any tests. The description Under the run configuration, eclipse can't even find the method which is annotated with @Test, but instead only shows me " (all methods) ". The following picture hopefully gives a better glimps of my setup: Console output: java.lang.NoClassDefFoundError: org/junit/platform/launcher/core/LauncherFactory at org.eclipse.jdt.internal.junit5.runner.JUnit5TestLoader.<init>(JUnit5TestLoader.java:31) at java.base/jdk.internal

I am trying to use JUnit 5 with Gradle after I succeeded in running a JUnit 4 test. Expected result: Tthe JUnit 4 test gave a nice 'passed' in the output and an html report in build/reports/tests . Actual result: The JUnit 5 test as below does not output anything besides (...) build succesful , while I know the test is not actually run since there is no test log output passed/skipped/failed, and putting a fail in the test keeps the build successful. Running gradle test --info yields Skipping task ':testClasses' as it has no actions. among a lot of I think mostly unrelevant output. Surprisingly
