This sample is the test application for the
|
|
<a href="../../../resources/tutorials/testing/activity_test.html">Activity
|
|
Testing</a> tutorial. It tests the <a href="../Spinner/index.html">Spinner</a> example
|
|
application.
|
|
</p>
|
|
<p>
|
|
The test application uses the
|
|
<a href="../../../reference/android/test/ActivityInstrumentationTestCase2.html"><code>ActivityInstrumentationTestCase2</code></a>
|
|
test case class,
|
|
which extends both <a href="../../../reference/android/app/Instrumentation">Android instrumentation</a> and the JUnit
|
|
<a href="../../../reference/junit/framework/TestCase.html"><code>TestCase</code></a>
|
|
class. The test runner is <a href="../../../reference/android/test/InstrumentationTestRunner.html"><code>InstrumentationTestRunner</code></a>.
|
|
</p>
|
|
<p>
|
|
The application shows how to set up a test application project,
|
|
how to create the <a href="AndroidManifest.html"><code>AndroidManifest.xml</code></a>
|
|
file for a test application, and how to set up a test case class for a test fixture. The
|
|
test case class, <a href="src/com/android/example/spinner/test/SpinnerActivityTest.html"><code>SpinnerActivityTest</code></a>,
|
|
contains tests that demonstrate the following Android test patterns:
|
|
</p>
|
|
<ul>
|
|
<li>
|
|
Test setup: The <code>setUp()</code> method re-initializes the state of the application under test
|
|
before each test is run.
|
|
</li>
|
|
<li>
|
|
Initial conditions: The <code>testPreconditions()</code> method demonstrates how to
|
|
test that the application under test is properly initialized prior to running the
|
|
test fixture.
|
|
</li>
|
|
<li>
|
|
UI interaction: The <code>testSpinnerUI()</code> method demonstrates how to send keystrokes
|
|
to the activity under test and then test the result.
|
|
</li>
|
|
<li>
|
|
Application control using instrumentation: The <code>testStateDestroy()</code> and <code>testStatePause()</code>
|
|
methods demonstrate how to use instrumentation to trigger stages in the lifecycle of the activity under test.
|
|
</li>
|
|
</ul>
|
|
<p>
|
|
The <a href="AndroidManifest.html">manifest</a> declares an <code><instrumentation></code> element
|
|
that links the test application with the application under test. Specifically, the
|
|
element's <code>android:name</code> attribute specifies <code>InstrumentationTestRunner</code> as the
|
|
instrumentation to use. The <code>android:targetPackage</code> attribute specifies
|
|
<code>com.android.example.spinner</code> as the name of the Android package that contains the
|
|
application under test.
