/**
* An {@link Instrumentation} that runs various types of {@link junit.framework.TestCase}s against
* an Android package (application). Typical usage:
* <ol>
* <li>Write {@link junit.framework.TestCase}s that perform unit, functional, or performance tests
* against the classes in your package. Typically these are subclassed from:
* <ul><li>{@link android.test.ActivityInstrumentationTestCase}</li>
* <li>{@link android.test.ActivityUnitTestCase}</li>
* <li>{@link android.test.AndroidTestCase}</li>
* <li>{@link android.test.ApplicationTestCase}</li>
* <li>{@link android.test.InstrumentationTestCase}</li>
* <li>{@link android.test.ProviderTestCase}</li>
* <li>{@link android.test.ServiceTestCase}</li>
* <li>{@link android.test.SingleLaunchActivityTestCase}</li></ul>
* <li>In an appropriate AndroidManifest.xml, define the this instrumentation with
* the appropriate android:targetPackage set.
* <li>Run the instrumentation using "adb shell am instrument -w",
* with no optional arguments, to run all tests (except performance tests).
* <li>Run the instrumentation using "adb shell am instrument -w",
* with the argument '-e func true' to run all functional tests. These are tests that derive from
* {@link android.test.InstrumentationTestCase}.
* <li>Run the instrumentation using "adb shell am instrument -w",
* with the argument '-e unit true' to run all unit tests. These are tests that <i>do not</i>derive
* from {@link android.test.InstrumentationTestCase} (and are not performance tests).
* <li>Run the instrumentation using "adb shell am instrument -w",
* with the argument '-e class' set to run an individual {@link junit.framework.TestCase}.
* </ol>
* <p/>
* <b>Running all tests:</b> adb shell am instrument -w
* com.android.foo/android.test.InstrumentationTestRunner
* <p/>
* <b>Running all small tests:</b> adb shell am instrument -w
* -e size small
* com.android.foo/android.test.InstrumentationTestRunner
* <p/>
* <b>Running all medium tests:</b> adb shell am instrument -w
* -e size medium
* com.android.foo/android.test.InstrumentationTestRunner
* <p/>
* <b>Running all large tests:</b> adb shell am instrument -w
* -e size large
* com.android.foo/android.test.InstrumentationTestRunner
* <p/>
* <b>Running a single testcase:</b> adb shell am instrument -w
* -e class com.android.foo.FooTest
* com.android.foo/android.test.InstrumentationTestRunner
* <p/>
* <b>Running a single test:</b> adb shell am instrument -w
* -e class com.android.foo.FooTest#testFoo
* com.android.foo/android.test.InstrumentationTestRunner
* <p/>
* <b>Running multiple tests:</b> adb shell am instrument -w
* -e class com.android.foo.FooTest,com.android.foo.TooTest
* com.android.foo/android.test.InstrumentationTestRunner
* <p/>
* <b>Including performance tests:</b> adb shell am instrument -w
* -e perf true
* com.android.foo/android.test.InstrumentationTestRunner
* <p/>
* <b>To debug your tests, set a break point in your code and pass:</b>
* -e debug true
* <p/>
* <b>To run in 'log only' mode</b>
* -e log true
* This option will load and iterate through all test classes and methods, but will bypass actual
* test execution. Useful for quickly obtaining info on the tests to be executed by an
* instrumentation command.
* <p/>
* <b>To generate EMMA code coverage:</b>
* -e coverage true
* Note: this requires an emma instrumented build. By default, the code coverage results file
* will be saved as /sdcard/coverage.ec, unless overridden by coverageFile flag (see below)
* <p/>
* <b> To specify EMMA code coverage results file path:</b>
* -e coverageFile /sdcard/myFile.ec
* <br/>
* in addition to the other arguments.
*/
/* (not JavaDoc)
* Although not necessary in most case, another way to use this class is to extend it and have the
* derived class return
* the desired test suite from the {@link #getTestSuite()} method. The test suite returned from this
* method will be used if no target class is defined in the meta-data or command line argument
* parameters. If a derived class is used it needs to be added as an instrumentation to the
* AndroidManifest.xml and the command to run it would look like:
* <p/>
* adb shell am instrument -w com.android.foo/<i>com.android.FooInstrumentationTestRunner</i>
* <p/>
* Where <i>com.android.FooInstrumentationTestRunner</i> is the derived class.
*
* This model is used by many existing app tests, but can probably be deprecated.
