to use the Instrumentation Framework to write test cases. Instrumentation testing allows you to verify a particular feature or behavior with an automated JUnit TestCase. You can launch activities and providers within an application, send key events, and make assertions about various UI elements. </p><p>You should have a working knowledge of the following:</p><ul> <li> Android Application Framework</li> <li> Using <code>adb</code>, <code>am</code> and various logging functionality </li> <li> A brief understanding of the application of interest, that is, the names of the classes which handle the intents etc. </li> <li> JUnit testing.</li></ul><p> Each Android application runs in its own process. Instrumentation kills the application process and restarts the process with Instrumentation. Instrumentation gives a handle to the application context used to poke around the application to validate test assertions, allowing you to write test cases to test applications at a much lower level than UI screen shot tests. Note that Instrumentation cannot catch UI bugs. </p><a name="androidInstrumentationTestingFramework"></a><h2>Instrumentation Framework</h2><a name="androidInstrumentationTestingClasses"></a><h3>Classes</h3><p> The following classes help glue together <code>Instrumentation</code> with JUnit testing. </p><table> <tr> <th scope="col">Class</th> <th scope="col">Description</th></tr> <tr> <td valign="top"><code>InstrumentationTestCase</code></td> <td valign="top"> <p>This extends the standard JUnit <code>TestCase</code> and offers access to an <code>Instrumentation</code> class. Write tests inside your instrumentation class any way you see fit. For example, your test might launch activities and send key events. For this to work properly, the instrumentation needs to be injected into the test case.</p> </td> </tr> <tr> <td valign="top"><code>InstrumentationTestRunner</code></td>⌨️ 快捷键说明
