Running ScalaTest Tests Under IntelliJ IDEA
2011-08-15
I had lots of difficulties running my tests under IDEA. The exact error message was:
Error running All Tests:
Not found suite class.
Where All Tests
was the name of my Run configuration.
I finally ended up with the right incantations. In my POM, I have the following:
1 <dependencies> 2 <dependency> 3 <groupId>junit</groupId> 4 <artifactId>junit</artifactId> 5 <version>4.8.1</version> 6 <scope>test</scope> 7 </dependency> 8 <dependency> 9 <groupId>org.scalatest</groupId> 10 <artifactId>scalatest_2.9.0-1</artifactId> 11 <version>1.6.1</version> 12 </dependency> 13 <dependency> 14 <groupId>org.mockito</groupId> 15 <artifactId>mockito-core</artifactId> 16 <version>1.8.1</version> 17 <scope>test</scope> 18 </dependency> 19 </dependencies>
Then, I had to extend org.scalatest.junit.JUnitSuite for my test classes, like this:
1 import JUnitSuite 2 import org.junit.Test 3 4 class GivenAnEmptyQueue extends JUnitSuite { 5 @Test def thenItShouldNotHaveAnyElements() { 6 assert(new Queue.empty) 7 } 8 }
Finally, I had to verify that both the JUnit and Scala plugins were enabled and at their latest versions in the IDE itself. After that, I was able to run my tests from within the IDE.
