New tests should be written using the[Android Testing Support Library](https://developer.android.com/tools/testing-support-library/index.html). This class provides functional testing of a single activity. The activity under test will be created using the system infrastructure (by calling InstrumentationTestCase.launchActivity()) and you will then be able to manipulate your Activity directly. Other options supported by this test case include: - You can run any test method on the UI thread (see[android.test.UiThreadTest](https://developer.android.com/reference/kotlin/android/test/UiThreadTest)). - You can inject custom Intents into your Activity (see[setActivityIntent(android.content.Intent)](https://developer.android.com/reference/kotlin/android/test/ActivityInstrumentationTestCase2#setActivityIntent(android.content.Intent))). This class replaces[android.test.ActivityInstrumentationTestCase](https://developer.android.com/reference/kotlin/android/test/ActivityInstrumentationTestCase), which is deprecated. New tests should be written using this base class. If you prefer an isolated unit test, see[android.test.ActivityUnitTestCase](https://developer.android.com/reference/kotlin/android/test/ActivityUnitTestCase). ## Summary | Public constructors || |------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|---| | [ActivityInstrumentationTestCase2](https://developer.android.com/reference/kotlin/android/test/ActivityInstrumentationTestCase2#ActivityInstrumentationTestCase2(java.lang.Class))`(`activityClass:` `[Class](https://developer.android.com/reference/kotlin/java/lang/Class.html#)!`)` Creates an[ActivityInstrumentationTestCase2](https://developer.android.com/reference/kotlin/android/test/ActivityInstrumentationTestCase2#). | | [ActivityInstrumentationTestCase2](https://developer.android.com/reference/kotlin/android/test/ActivityInstrumentationTestCase2#ActivityInstrumentationTestCase2(kotlin.String,%20java.lang.Class))`(`pkg:` `[String](https://kotlinlang.org/api/latest/jvm/stdlib/kotlin/-string/index.html)!`, `activityClass:` `[Class](https://developer.android.com/reference/kotlin/java/lang/Class.html#)!`)` Creates an[ActivityInstrumentationTestCase2](https://developer.android.com/reference/kotlin/android/test/ActivityInstrumentationTestCase2#). | | Public methods || |----------------------------------------------------------------------------------|------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------| | openT | [getActivity](https://developer.android.com/reference/kotlin/android/test/ActivityInstrumentationTestCase2#getActivity())`()` Get the Activity under test, starting it if necessary. | | open[Unit](https://kotlinlang.org/api/latest/jvm/stdlib/kotlin/-unit/index.html) | [setActivityInitialTouchMode](https://developer.android.com/reference/kotlin/android/test/ActivityInstrumentationTestCase2#setActivityInitialTouchMode(kotlin.Boolean))`(`initialTouchMode:` `[Boolean](https://kotlinlang.org/api/latest/jvm/stdlib/kotlin/-boolean/index.html)`)` Call this method before the first call to[getActivity](https://developer.android.com/reference/kotlin/android/test/ActivityInstrumentationTestCase2#getActivity())to set the initial touch mode for the Activity under test. | | open[Unit](https://kotlinlang.org/api/latest/jvm/stdlib/kotlin/-unit/index.html) | [setActivityIntent](https://developer.android.com/reference/kotlin/android/test/ActivityInstrumentationTestCase2#setActivityIntent(android.content.Intent))`(`i:` `[Intent](https://developer.android.com/reference/kotlin/android/content/Intent.html#)!`)` Call this method before the first call to[getActivity](https://developer.android.com/reference/kotlin/android/test/ActivityInstrumentationTestCase2#getActivity())to inject a customized Intent into the Activity under test. | | Protected methods || |----------------------------------------------------------------------------------|---------------------------------------------------------------------------------------------------------------------------------------------------| | open[Unit](https://kotlinlang.org/api/latest/jvm/stdlib/kotlin/-unit/index.html) | [runTest](https://developer.android.com/reference/kotlin/android/test/ActivityInstrumentationTestCase2#runTest())`()` Runs the current unit test. | | open[Unit](https://kotlinlang.org/api/latest/jvm/stdlib/kotlin/-unit/index.html) | [setUp](https://developer.android.com/reference/kotlin/android/test/ActivityInstrumentationTestCase2#setUp())`()`

Utility method for launching an activity. The[Intent](https://developer.android.com/reference/kotlin/android/content/Intent.html#)used to launch the Activity is: action =[Intent.ACTION_MAIN](https://developer.android.com/reference/kotlin/android/content/Intent.html#ACTION_MAIN:kotlin.String)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.

| | [Unit](https://kotlinlang.org/api/latest/jvm/stdlib/kotlin/-unit/index.html) | [runTest](https://developer.android.com/reference/kotlin/android/test/InstrumentationTestCase#runTest())`()`
Runs the current unit test. If the unit test is annotated with[android.test.UiThreadTest](https://developer.android.com/reference/kotlin/android/test/UiThreadTest), the test is run on the UI thread.
| | [Unit](https://kotlinlang.org/api/latest/jvm/stdlib/kotlin/-unit/index.html) | [runTestOnUiThread](https://developer.android.com/reference/kotlin/android/test/InstrumentationTestCase#runTestOnUiThread(java.lang.Runnable))`(`r:` `[Runnable](https://developer.android.com/reference/kotlin/java/lang/Runnable.html#)!`)`
Helper for running portions of a test on the UI thread. Note, in most cases it is simpler to annotate the test method with[android.test.UiThreadTest](https://developer.android.com/reference/kotlin/android/test/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.
| | [Unit](https://kotlinlang.org/api/latest/jvm/stdlib/kotlin/-unit/index.html) | [sendKeys](https://developer.android.com/reference/kotlin/android/test/InstrumentationTestCase#sendKeys(kotlin.Int))`(`vararg` `keys:` `[Int](https://kotlinlang.org/api/latest/jvm/stdlib/kotlin/-int/index.html)`)`
Sends a series of key events through instrumentation and waits for idle. For instance: sendKeys(KEYCODE_DPAD_LEFT, KEYCODE_DPAD_CENTER).
| | [Unit](https://kotlinlang.org/api/latest/jvm/stdlib/kotlin/-unit/index.html) | [sendKeys](https://developer.android.com/reference/kotlin/android/test/InstrumentationTestCase#sendKeys(kotlin.String))`(`keysSequence:` `[String](https://kotlinlang.org/api/latest/jvm/stdlib/kotlin/-string/index.html)!`)`
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").
| | [Unit](https://kotlinlang.org/api/latest/jvm/stdlib/kotlin/-unit/index.html) | [sendRepeatedKeys](https://developer.android.com/reference/kotlin/android/test/InstrumentationTestCase#sendRepeatedKeys(kotlin.Int))`(`vararg` `keys:` `[Int](https://kotlinlang.org/api/latest/jvm/stdlib/kotlin/-int/index.html)`)`
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).
| | [Unit](https://kotlinlang.org/api/latest/jvm/stdlib/kotlin/-unit/index.html) | [tearDown](https://developer.android.com/reference/kotlin/android/test/InstrumentationTestCase#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.
