Using TestNG in Scala: By Example

Here is a very, very simple example of some TestNG stuff that I wrote the other day in Scala (it can also be found here):

package com.joshcough.cpu.electric;

import org.testng.annotations._
import org.testng.Assert_

package com.joshcough.cpu.electric;

import org.testng.annotations._
import org.testng.Assert._

class GeneratorTest {

  @Test
  def expectNewGeneratorToBeOn() = {
     val gen: Generator = new Generator
        assertTrue(gen.isOn);
    }
  
  @Test
  def expectTurnedOffGeneratorIsOff() = {
        val gen: Generator = new Generator
        gen.turnOff
        assertTrue(gen.isOff);
    }  
}

This might not be the prettiest code in the world, but:

• It works (which is more than I could accomplish with others)
• I can run it in my IDE
• I can run it in Ant
• I only have to do exactly what I ever did with Java
• Its still way better than JUnit

There were a few things I had to do to make this work:

• When compiling in Ant, I had to add this to my scalac call:
  
• target="jvm-1.5" ...
• When compiling in Eclipse I had to do this:
• Project -> Properties -> Scala Compiler Properties -> target = jvm-1.5

I could give a more detailed example, but I haven't tried it yet. I'm pretty sure that things like @BeforeMethod, @AfterClass, @DataProvider and what not all just work the same. I'll try to come up with a better example though.
