| <p>TestNG is a testing framework inspired from JUnit and NUnit but introducing |
| some new functionalities that make it more powerful and easier to use, such as:</p> |
| <ul> |
| <li>JDK 5 Annotations (JDK 1.4 is also supported with JavaDoc annotations). |
| </li> |
| <li>Flexible test configuration. |
| </li> |
| <li>Support for data-driven testing (with <tt>@DataProvider</tt>).</li> |
| <li>Support for parameters.</li> |
| <li>Allows distribution of tests on slave machines.</li> |
| <li>Powerful execution model (no more <tt>TestSuite</tt>). |
| </li> |
| <li>Supported by a variety of tools and plug-ins (Eclipse, IDEA, Maven, |
| etc...). |
| </li> |
| <li>Embeds BeanShell for further flexibility. |
| </li> |
| <li>Default JDK functions for runtime and logging (no dependencies). |
| </li> |
| <li>Dependent methods for application server testing.</li> |
| </ul> |
| <p>TestNG is designed to cover all categories of tests: unit, functional, |
| end-to-end, integration, etc...</p> |
| <p>I started TestNG out of frustration for some JUnit deficiencies which I have |
| documented on my weblog <a href="http://jroller.com/page/cbeust/20030425">here</a>, |
| <a href="http://www.jroller.com/page/cbeust/20030317">here</a>, <a href="http://www.beust.com/weblog/archives/000173.html">here</a> and in |
| particular, <a href="http://www.beust.com/weblog/archives/000082.html">here</a> |
| Reading these entries might give you a better idea of the goal I am trying to |
| achieve with TestNG. You can also check out a quick |
| <a href="http://www.beust.com/weblog/archives/000176.html">overview of the main |
| features</a> and an <a href="http://www.beust.com/weblog/archives/000170.html"> |
| article</a> describing a very concrete example where the combined use of several |
| TestNG's features provides for a very intuitive and maintainable testing design.</p> |
| <p>Here is a very simple test:</p> |
| |
| <pre class="code"> |
| <span class=j_eclipse_keyword>package example1;</span> |
| |
| <span class=j_eclipse_keyword>import</span> <span class=j_eclipse_pkgname>org.testng</span>.<span class=j_eclipse_pkgname>annotations</span>.<span class=j_eclipse_pkgname>*</span>; |
| |
| <span class=j_eclipse_keyword>public</span> <span class=j_eclipse_keyword>class</span> <span class=j_eclipse_classname>SimpleTest</span> { |
| |
| @<span class=j_eclipse_classname>Configuration</span>(beforeTestClass = <span class=j_eclipse_constant>true</span>) |
| <span class=j_eclipse_keyword>public</span> <span class=j_eclipse_typekeyw>void</span> <span class=j_eclipse_methname>setUp</span>() { |
| <span class=j_eclipse_comment>// code that will be invoked when this test is instantiated</span> |
| } |
| |
| @<span class=j_eclipse_classname>Test</span>(groups = { <span class=j_eclipse_string>"fast"</span> }) |
| <span class=j_eclipse_keyword>public</span> <span class=j_eclipse_typekeyw>void</span> <span class="j_eclipse_methname">aFastTest</span>() { |
| <span class="j_eclipse_comment">System.out.println("Fast test");</span> |
| } |
| |
| @<span class=j_eclipse_classname>Test</span>(groups = { <span class=j_eclipse_string>"slow"</span> }) |
| <span class=j_eclipse_keyword>public</span> <span class=j_eclipse_typekeyw>void</span> <span class="j_eclipse_methname">aSlowTest</span>() { |
| <span class="j_eclipse_comment">System.out.println("Slow test");</span> |
| } |
| |
| } |
| </pre> |
| |
| The method <tt>setUp()</tt> will be invoked after the test class has been built and before |
| any test method is run. In this example, we will be running the group |
| fast, so <tt>aFastTest()</tt> will be invoked while <tt>aSlowTest()</tt> will be |
| skipped.<p> |
| <!------------------------------------- |
| |
| WRITING A TEST |
| |
| ------------------------------------> |
| |
| Things to note:</p><ul> |
| <li>No need to extend a class or implement an interface.</li><li>Even though the example above uses the JUnit conventions, our methods |
| can be called any name you like, it's the annotations that tell TestNG what |
| they are.</li><li>A test method can belong to one or several groups. These groups will be |
| used at runtime to determine what test methods should be invoked..</li></ul> |
| |
| <p> |
| |
| Once you have compiled your test class into the <tt>build</tt> directory, you |
| can invoke your test with the command line, an ant task (shown below) or an XML |
| file:<pre class="code"><<span class="tag">project </span><span class="attribute">default="test"</span>> |
| |
| <<span class="tag">path </span><span class="attribute">id="cp"</span>> |
| <<span class="tag">pathelement </span><span class="attribute">location="lib/testng-testng-4.4-jdk15.jar"</span>/> |
| <<span class="tag">pathelement </span><span class="attribute">location="build"</span>/> |
| <<span class="tag">/path</span>> |
| |
| <<span class="tag">taskdef </span><span class="attribute">name="testng" classpathref="cp" |
| classname="org.testng.TestNGAntTask" /</span>> |
| |
| <<span class="tag">target </span><span class="attribute">name="test"</span>> |
| <<span class="tag">testng </span><span class="attribute">classpathref="cp" groups="fast"</span>> |
| <<span class="tag">classfileset</span><span class="attribute"> dir="build" includes="example1/*.class"</span>/> |
| <<span class="tag">/testng</span>> |
| <<span class="tag">/target</span>> |
| |
| <<span class="tag">/project</span>></pre>Use ant to invoke it:<pre class="code"> |
| c:> ant |
| Buildfile: build.xml |
| |

| <h3><a name="requirements">Requirements</a></h3> |
| <p>TestNG runs on JDK 1.4 and 5. The examples shown in this |
| documentation assume JDK 5 and therefore, use JDK 5 annotations, but they |
| can easily be translated to JDK 1.4 JavaDoc-type annotations. See the JDK |
| 1.4 section for details.</p> |
| |
