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>&lt;instrumentation&gt;</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.
