Can't get Maven to run JUnit tests

Question

I think I've tried everything in the old StackOverflow thread about this with no success.

I have a Java project with a junit jupiter test class in src/test/java, called SacmElementTest. If I run this as a JUnit test from Eclipse the tests run fine - there are 8 of them in there. But if I run the tests from Maven (within eclipse or from the command line) everything seems to be fine but I get Tests run: 0, Failures: 0, Errors: 0, Skipped: 0, so it's not actually running the tests. My pom file is:

What am I doing wrong?

Please also post your project directory struture from project explorer. — Amith Kumar, Jul 03 '18 at 03:40
share your source folder structure. maven by default follow `src/test/**` if entry is there is classpath — Sagar Kharab, Jul 03 '18 at 04:10

Please add maven surefire plugin with correct dependency as described here for Junit 5 with Jupiter.

<plugin>
    <artifactId>maven-surefire-plugin</artifactId>
    <version>2.21.0</version>
    <dependencies>
        <dependency>
            <groupId>org.junit.platform</groupId>
            <artifactId>junit-platform-surefire-provider</artifactId>
            <version>1.2.0</version>
        </dependency>
        <dependency>
            <groupId>org.junit.jupiter</groupId>
            <artifactId>junit-jupiter-engine</artifactId>
            <version>5.2.0</version>
        </dependency>
    </dependencies>
</plugin>

Release 2.22.0 of the Surefire plugin has support for JUnit Jupiter built-in. According to its documentation you have to add the JUnit Jupiter engine to the project dependencies.

<project ...>
  ...
  <dependencies>
    ...
    <dependency>
      <groupId>org.junit.jupiter</groupId>
      <artifactId>junit-jupiter-engine</artifactId>
      <version>5.2.0</version>
      <scope>test</scope>
    </dependency>
    ...
  </dependencies>
  ...
  <build>
    <plugins>
      ...
      <plugin>
        <artifactId>maven-surefire-plugin</artifactId>
        <version>2.22.0</version>
      </plugin>
      ...
    </plugins>
  </build>
</project>
