class JUnit3Suite extends TestCase with Suite with AssertionsForJUnit

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

A JUnit3Suite may be run by either JUnit 3 (such as JUnit 3.8) or ScalaTest's runner. You write it the way you write a JUnit 3 TestCase. Tests are methods that start with test, take no parameters, and have a Unit return type. You manage fixtures with methods setUp and tearDown. Here's an example:

import org.scalatest.junit.JUnit3Suite
import scala.collection.mutable.ListBuffer

class BlastFromThePastSuite extends JUnit3Suite {

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

  override def setUp(): Unit = {
    sb = new StringBuilder("ScalaTest is ")
    lb = new ListBuffer[String]
  }

  def testEasy(): Unit = { // Uses JUnit-style assertions
    sb.append("easy!")
    assertEquals("ScalaTest is easy!", sb.toString)
    assertTrue(lb.isEmpty)
    lb += "sweet"
  }

  def testFun(): Unit = { // Uses ScalaTest assertions
    sb.append("fun!")
    assert(sb.toString === "ScalaTest is fun!")
    assert(lb.isEmpty)
  }
}

You can use either JUnit's assertions, inherited from TestCase, or ScalaTest's, inherited from AssertionsForJUnit.

When writing JUnit 3 tests in Scala, you should keep in mind that JUnit 3 will not run tests that have a return type other than Unit. Thus it is best to explicitly state the Unit result type, like this:

def testGoodIdea(): Unit = { // result type will be Unit
  // ...
}

Instead of this:

def testBadIdea() = { // result type will be inferred
  // ...
}

If the testBadIdea method ends in an expression that has a result type other than Unit, the Scala compiler will infer a result type to the testBadIdea method to be the same non-Unit type. As a "result," JUnit 3 will not discover or run the testBadIdea method at all.
