| <p>The Java test generator generates test cases based on JUnit. |
| An example is included in CommaSuite and can be imported by clicking File (left-top) → New → Example → <em>Test Generation Example</em> → Next → Finish. |
| Running the generator (right click on the <code>.prj</code> file → Execute CommaSuite Workflow) will generate the test cases under <code>src-gen/test.interfaceCamera/TestCases.java</code> (which can be executed by right click on <code>TestCases.java</code> → Run As → JUnit Test):</p> |

| <p>The <code>adapter</code> is reponsible for doing the communication with the system under test (SUT). The <code>(before|after)(All|Each)</code> methods allow the adapter to do any setup/teardown of the SUT.</p> |
| </div> |
| <div class="paragraph"> |
| <p>The <code>testScenario*</code> methods contain the test cases. Each test case starts with a human readable description followed by the test code. As can be seen above, methods are called and the return value (if any) is checked. Also any expected notifications are checked.</p> |
| </div> |
| <div class="paragraph"> |
| <p>The adapter code contains system specific logic and is therefore manually written. The example can be found under <code>src/test.interfaceCamera/Adapter.java</code>. This adapter contains:</p> |
| </div> |
| <div class="ulist"> |
| <ul> |
| <li> |
| <p>Classes to handle and check events generated by the SUT (<code>AutoResetEvent</code>, <code>Event</code>, <code>EventHandler</code>)</p> |
| </li> |
| <li> |
| <p>The <code>call</code> method to execute a command/signal on the SUT with a given set of parameters.</p> |
| </li> |
| <li> |
| <p>Before and after each call the <code>beforeEvent</code> and <code>afterEvent</code> methods are called. These method can be used to trigger any non-standard behaviour on the interface (e.g. an error situation which would normally not occur).</p> |
| </li> |
| </ul> |

| <div class="paragraph"> |
| <p>The <em>Test Generation Example</em> also contains an example for components. The testcases can be found under <code>src-gen/test.componentCamera/TestCases.java</code>.</p> |
