Trait that contains ScalaTest's basic assertion methods, suitable for use with JUnit.

A Suite that is also a junit.framework.TestCase.

A JUnit Runner that knows how to run any ScalaTest Suite (or Spec, which extends Suite). This enables you to provide a JUnit RunWith annotation on any ScalaTest Suite. Here's an example:

 import org.junit.runner.RunWith
 import org.scalatest.junit.JUnitRunner
 import org.scalatest.FunSuite

 @RunWith(classOf[JUnitRunner])
 class MySuite extends FunSuite {
   // ...
 }
 

A suite of tests that can be run with either JUnit or ScalaTest. This trait allows you to write JUnit 4 tests with ScalaTest's more concise assertion syntax as well as JUnit's assertions (assertEquals, etc.). You create tests by defining methods that are annotated with Test, and can create fixtures with methods annotated with Before and After. For example:

 import org.scalatest.junit.JUnitSuite
 import scala.collection.mutable.ListBuffer
 import _root_.org.junit.Test
 import _root_.org.junit.Before

 class TwoSuite extends JUnitSuite {

   var sb: StringBuilder = _
   var lb: ListBuffer[String] = _

   @Before override def initialize() {
     sb = new StringBuilder("ScalaTest is ")
     lb = new ListBuffer[String]
   }

   @Test def verifyEasy() {
     sb.append("easy!")
     assert(sb.toString === "ScalaTest is easy!")
     assert(lb.isEmpty)
     lb += "sweet"
   }

   @Test def verifyFun() {
     sb.append("fun!")
     assert(sb.toString === "ScalaTest is fun!")
     assert(lb.isEmpty)
   }
 }
 

Exception that indicates a test failed.

Trait that makes ScalaTest's MustMatchers DSL syntax available for use with JUnit.

Trait that makes ScalaTest's ShouldMatchers DSL syntax available for use with JUnit.

Companion object that facilitates the importing of AssertionsForJUnit members as an alternative to mixing it in. One use case is to import AssertionsForJUnit members so you can use them in the Scala interpreter:
