junit-extensions

Extensions to JUnit providing additional assertions.
This project is inspired by the Scala Test libraries and how one can mix in Traits to get new behavior in the test code.
Java 8 introduced default methods in Interfaces providing much similar functionality as the Trait in Scala.
With that in the toolbox this library introduces interfaces with additional assert operations. It allows you as a programmer to write test classes and mix-in additional interfaces to get richer assert operations.

How To Use

import static javascalautils.OptionCompanion.Option;
import static javascalautils.TryCompanion.Try;

import junitextensions.OptionAssert;
import junitextensions.TryAssert;

import org.junit.Test;

/**
 * Example test class illustrating how to use the assert interfaces from this library. 
 * The interfaces allows mixing in new behavior.
 * @author Peter Nerg
 */
public class ExampleTestClass implements OptionAssert, TryAssert {

	@Test
	public void assertingSome() {
		String expected = "Some is never None";
		//this method is inherited from OptionAssert
		assertSomeEquals(expected, Option(expected));
	}
	
	@Test
	public void getNoneExistingItemFromMap() {
		//this method is inherited from OptionAssert
		assertIsNone(Option(null));
	}
	
	@Test
	public void assertingSuccess(){
		//this method is inherited from TryAssert
		assertSuccessEquals(66, Try(() -> 33*2));
	}

	@Test
	public void assertingFailure(){		
		//this method is inherited from TryAssert
		assertIsFailure(Try(() -> 69/0)); //division by zero, will fail
	}
}
