Trying to get ScalaTest working: “There are no tests to run” when doing “mvn test”

Question

Edit: I finally got it to work!!!

It needed a combination of JUnit in the pom.xml, and three statements in my .scala:

import org.junit.runner.RunWith

You might want to use the scalatest-maven-plugin to run your scala tests.

Also make sure that you use the test for jars needed only for test purposes.

This is how I have defined my pom.xml for using ScalaTest:

    4.0.0

    1.0-SNAPSHOT

    ${project.artifactId}-${project.version}

    
        UTF-8
        2.9.2
        2.0.M4
    

    
        
            org.scala-lang
            scala-library
            ${scala.version}
        
        
            org.scalatest
            scalatest_${scala.version}
            ${scalatest.version}
            test
        
    

    
        
            
                org.scala-tools
                maven-scala-plugin
                2.15.2
                
                    
                        scala-compile
                        
                            compile
                            testCompile
                        
                        
                            
                                -make:transitive
                                -dependencyfile
                                ${project.build.directory}/.scala_dependencies
                            
                        
                    
                
            
            
            
                org.scalatest
                scalatest-maven-plugin
                1.0-M2
                
                    ${project.build.directory}/surefire-reports
                    W 
                
                
                    
                        scala-test
                        
                            test
                        
                    
                
            
        
    

As you can see I have also added a section that disables the surefire plugin if you really don't want to run it. It is commented in the above pom but if you want to disable the surefire plugin just uncomment that part.

I am using IntelliJ too and there are no problems at all with this combination. Just run the tests from within IntelliJ or by using mvn test, they will both work.
