Public constructors

InstrumentationTestCase

public InstrumentationTestCase ()

Public methods

getInstrumentation

public Instrumentation getInstrumentation ()

Inheritors can access the instrumentation using this.

Returns
`Instrumentation`	instrumentation

injectInsrumentation

public void injectInsrumentation (Instrumentation instrumentation)

This method is deprecated.
Incorrect spelling, use injectInstrumentation(android.app.Instrumentation) instead.

Injects instrumentation into this test case. This method is called by the test runner during test setup.

Parameters
`instrumentation`	`Instrumentation`: the instrumentation to use with this instance

injectInstrumentation

public void injectInstrumentation (Instrumentation instrumentation)

Injects instrumentation into this test case. This method is called by the test runner during test setup.

Parameters
`instrumentation`	`Instrumentation`: the instrumentation to use with this instance

launchActivity

public final T launchActivity (String pkg, 
                Class<T> activityCls, 
                Bundle extras)

Utility method for launching an activity.

The Intent used to launch the Activity is: action = Intent#ACTION_MAIN extras = null, unless a custom bundle is provided here All other fields are null or empty.

NOTE: The parameter pkg must refer to the package identifier of the package hosting the activity to be launched, which is specified in the AndroidManifest.xml file. This is not necessarily the same as the java package name.

Parameters
`pkg`	`String`: The package hosting the activity to be launched.
`activityCls`	`Class`: The activity class to launch.
`extras`	`Bundle`: Optional extra stuff to pass to the activity.

Returns
`T`	The activity, or null if non launched.

launchActivityWithIntent

public final T launchActivityWithIntent (String pkg, 
                Class<T> activityCls, 
                Intent intent)

Utility method for launching an activity with a specific Intent.

Parameters
`pkg`	`String`: The package hosting the activity to be launched.
`activityCls`	`Class`: The activity class to launch.
`intent`	`Intent`: The intent to launch with

Returns
`T`	The activity, or null if non launched.

runTestOnUiThread

public void runTestOnUiThread (Runnable r)

Helper for running portions of a test on the UI thread. Note, in most cases it is simpler to annotate the test method with UiThreadTest, which will run the entire test method on the UI thread. Use this method if you need to switch in and out of the UI thread to perform your test.

Parameters
`r`	`Runnable`: runnable containing test code in the `Runnable#run()` method

Throws
`Throwable`

sendKeys

public void sendKeys (String keysSequence)

Sends a series of key events through instrumentation and waits for idle. The sequence of keys is a string containing the key names as specified in KeyEvent, without the KEYCODE_ prefix. For instance: sendKeys("DPAD_LEFT A B C DPAD_CENTER"). Each key can be repeated by using the N* prefix. For instance, to send two KEYCODE_DPAD_LEFT, use the following: sendKeys("2*DPAD_LEFT").

Parameters
`keysSequence`	`String`: The sequence of keys.

sendKeys

public void sendKeys (int... keys)

Sends a series of key events through instrumentation and waits for idle. For instance: sendKeys(KEYCODE_DPAD_LEFT, KEYCODE_DPAD_CENTER).

Parameters
`keys`	`int`: The series of key codes to send through instrumentation.

sendRepeatedKeys

public void sendRepeatedKeys (int... keys)

Sends a series of key events through instrumentation and waits for idle. Each key code must be preceded by the number of times the key code must be sent. For instance: sendRepeatedKeys(1, KEYCODE_DPAD_CENTER, 2, KEYCODE_DPAD_LEFT).

Parameters
`keys`	`int`: The series of key repeats and codes to send through instrumentation.

Protected methods

runTest

protected void runTest ()

Runs the current unit test. If the unit test is annotated with UiThreadTest, the test is run on the UI thread.

Throws
`Throwable`

tearDown

protected void tearDown ()

Make sure all resources are cleaned up and garbage collected before moving on to the next test. Subclasses that override this method should make sure they call super.tearDown() at the end of the overriding method.

Throws
	java.lang.Exception
`Exception`
