1<p> 2 This sample is the test application for the 3 <a href="../../../resources/tutorials/testing/activity_test.html">Activity 4 Testing</a> tutorial. It tests the <a href="../Spinner/index.html">Spinner</a> example 5 application. 6</p> 7<p> 8 The test application uses the 9<a href="../../../reference/android/test/ActivityInstrumentationTestCase2.html"><code>ActivityInstrumentationTestCase2</code></a> 10 test case class, 11 which extends both <a href="../../../reference/android/app/Instrumentation">Android instrumentation</a> and the JUnit 12<a href="../../../reference/junit/framework/TestCase.html"><code>TestCase</code></a> 13 class. The test runner is <a href="../../../reference/android/test/InstrumentationTestRunner.html"><code>InstrumentationTestRunner</code></a>. 14</p> 15<p> 16 The application shows how to set up a test application project, 17 how to create the <a href="AndroidManifest.html"><code>AndroidManifest.xml</code></a> 18 file for a test application, and how to set up a test case class for a test fixture. The 19 test case class, <a href="src/com/android/example/spinner/test/SpinnerActivityTest.html"><code>SpinnerActivityTest</code></a>, 20 contains tests that demonstrate the following Android test patterns: 21</p> 22 <ul> 23 <li> 24 Test setup: The <code>setUp()</code> method re-initializes the state of the application under test 25 before each test is run. 26 </li> 27 <li> 28 Initial conditions: The <code>testPreconditions()</code> method demonstrates how to 29 test that the application under test is properly initialized prior to running the 30 test fixture. 31 </li> 32 <li> 33 UI interaction: The <code>testSpinnerUI()</code> method demonstrates how to send keystrokes 34 to the activity under test and then test the result. 35 </li> 36 <li> 37 Application control using instrumentation: The <code>testStateDestroy()</code> and <code>testStatePause()</code> 38 methods demonstrate how to use instrumentation to trigger stages in the lifecycle of the activity under test. 39 </li> 40 </ul> 41<p> 42 The <a href="AndroidManifest.html">manifest</a> declares an <code><instrumentation></code> element 43 that links the test application with the application under test. Specifically, the 44 element's <code>android:name</code> attribute specifies <code>InstrumentationTestRunner</code> as the 45 instrumentation to use. The <code>android:targetPackage</code> attribute specifies 46 <code>com.android.example.spinner</code> as the name of the Android package that contains the 47 application under test. 48</p> 49<img alt="The initial user interface for the Spinner sample application" style="height:230px;" 50 src="../images/SpinnerTest1.png"/> 51<img alt="The JUnit view in Eclipse with ADT, showing a successful test run of SpinnerTest" style="height:230px;" 52 src="../images/SpinnerTest2.png"/> 53
