Getting Started

Note: This is very much a work in progress.

Creating a New Test Case

Here is a template for writing JUnit4-style tests:

package com.example.foo;

import static org.junit.Assert.assertEquals;

import org.junit.Test;
import org.junit.Ignore;
import org.junit.runner.RunWith;
import org.junit.runners.JUnit4;

/**
 * Tests for {@link Foo}.
 *
 * @author [email protected] (John Doe)
 */
@RunWith(JUnit4.class)
public class FooTest {

    @Test
    public void thisAlwaysPasses() {
    }

    @Test
    @Ignore
    public void thisIsIgnored() {
    }
}

To run a test on the command line. Use something like this: java -cp .:/usr/share/java/junit.jar org.junit.runner.JUnitCore [test class name]

Notes

• All test methods are annotated with @Test. Unlike JUnit3 tests, you do not need to prefix the method name with "test" (and usually don't)
• Do not have your test classes extend junit.framework.TestCase (directly or indirectly). Usually, tests with JUnit4 do not need to extend anything (which is good, since Java does not support multiple inheritance)
• Do not use any classes in junit.framework or junit.extensions
