This document is intended to help Maven Developers test plugins with unit tests, integration tests, and functional tests.</p></section><section> +<h1>Testing Styles: Unit Testing vs. Functional/Integration Testing</h1> <p>A unit test attempts to verify a mojo as an isolated unit, by mocking out the rest of the Maven environment. A mojo unit test does not attempt to run your plugin in the context of a real Maven build. Unit tests are designed to be fast.</p> <p>A functional/integration test attempts to use a mojo in a real Maven build, by launching a real instance of Maven in a real project. Normally this requires you to construct special dummy Maven projects with real POM files. Often this requires you to have already installed your plugin into your local repository so it can be used in a real Maven build. Functional tests run much more slowly than unit tests, but they can catch bugs that you may not catch with unit tests.</p> <p>The general wisdom is that your code should be mostly tested with unit tests, but should also have some functional tests.</p></section><section> -<h2>Unit Tests</h2><section> -<h3>Using JUnit alone</h3> +<h1>Unit Tests</h1><section> +<h2>Using JUnit alone</h2> <p>In principle, you can write a unit test of a plugin Mojo the same way you'd write any other JUnit test case, by writing a class that <code>extends TestCase</code>.</p> <p>However, most mojos need more information to work properly.
