Question

The "mvn test" compiles my test case, but it does not run it:

        <artifactId>junit-vintage-engine</artifactId>
        <version>${junit.vintage.version}</version>
        <scope>test</scope>
    </dependency>

The test class is in the testSourceDirectory directory, its name begins with "Test", and it has the @Test annotation.

I suspect that the tests are not executed because the packaging is "war" instead of "jar". But I cannot change that - there is a single "packaging" setting for the whole project, and it must be "war" because it is really a web app.

So how do run my tests, and keep the "war" packaging at the same time?

UPDATE After adding the suggessted surefire provider, the test fails. surefire-reports/*.dump file shows this traceback:

Answer 1

JUnit 5 will works fine with following combination of dependencies and plugin version, both in JDK 8/11. 

Dependency
<dependency>
    <groupId>org.junit.jupiter</groupId>
    <artifactId>junit-jupiter-api</artifactId>
    <version>5.2.0</version>
    <scope>test</scope>
</dependency>
<dependency>
    <groupId>org.junit.jupiter</groupId>
    <artifactId>junit-jupiter-engine</artifactId>
    <version>5.2.0</version>
    <scope>test</scope>
</dependency>

Build
<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-surefire-plugin</artifactId>
    <version>2.22.0</version>
</plugin>

Answer 2

似乎是2.21.0中org.apache.maven.surefire.report.RunListener.testSetStarting was changed的签名。 junit-platform-surefire-provider依赖于surefire-api.2.19.1，因此它调用testSetStarting，其实例为ReportEntry，方法现在接受TestSetReportEntry。

依赖关系为upgraded to 2.21.0，因此我们只需等待junit 5的下一个版本。

我已经建立了junit的当前主分支，并且可以确认junit-platform-1.2.0-SNAPSHOT和juniper-5.2.0-SNAPSHOT按预期工作。
