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

/**
 * Tests for {@link Foo}.
 *
 * @author user@example.com (John Doe)
 */
@RunWith(JUnit4.class)
public class FooTest {

  @Test
  public void thisAlwaysPasses() {
  }

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

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
