Answer 1

For me, the issue was because I excluded the test from compilation in the POM. My pom.xml looked like this:

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-compiler-plugin</artifactId>
    <version>3.5.1</version>
    <configuration>
        <source>1.8</source>
        <target>1.8</target>
        <testExcludes>
            <exclude>com/mycompany/app/AppTest.java</exclude>
        </testExcludes>
    </configuration>
</plugin>

After removing the <exclude>, I was able to run the tests in AppTest.java again.
