How do you unit test Scala in Eclipse?

Question

I am learning Scala and would like to set up integrated unit testing in Eclipse. As far as I can tell from googling, ScalaTest is the way to go, possibly in combination with JUnit.

What are your experiences with unit testing Scala in Eclipse? Should I use the JUnit runner or something else?

Answer 1

There is a wiki page on the ScalaIDE website on how to run Scala unit tests in Eclipse. If you have specific issues with running specs unit tests, I encourage you to post messages on the specs-users mailing list.

Answer 2

I was unable to run the ScalaTest specs with JUnit runner inside eclipse. I think this is because of the absence of the @Test annotated methods. However if your project has Maven support, you can run your specs from command line using mvn test. For Surefire plugin to detect your specs, use the following configuration in your pom file.

<plugin>
  <groupId>org.apache.maven.plugins</groupId>
  <artifactId>maven-surefire-plugin</artifactId>
  <version>2.5</version>
  <configuration>
   <includes>
    <include>**/*Spec.class</include>
   </includes>
  </configuration>
</plugin>
