This class was deprecated in API level 24.
Write Local Unit Tests instead.

This class provides isolated testing of a single activity. The activity under test will be created with minimal connection to the system infrastructure, and you can inject mocked or wrappered versions of many of Activity's dependencies. Most of the work is handled automatically here by setUp() and tearDown().

If you prefer a functional test, see ActivityInstrumentationTestCase.

It must be noted that, as a true unit test, your Activity will not be running in the normal system and will not participate in the normal interactions with other Activities. The following methods should not be called in this configuration - most of them will throw exceptions:

The following methods may be called but will not do anything. For test purposes, you can use the methods getStartedActivityIntent() and getStartedActivityRequest() to inspect the parameters that they were called with.

The following methods may be called but will not do anything. For test purposes, you can use the methods isFinishCalled() and getFinishedActivityRequest() to inspect the parameters that they were called with.

Summary

Public constructors

ActivityUnitTestCase(Class<T> activityClass)

Public methods

T getActivity()
int getFinishedActivityRequest()

This method will return the request code if the Activity under test called finishActivity(int).

int getRequestedOrientation()

This method will return the value if your Activity under test calls setRequestedOrientation(int).

Intent getStartedActivityIntent()

This method will return the launch intent if your Activity under test calls startActivity(Intent) or startActivityForResult(Intent, int).

int getStartedActivityRequest()

This method will return the launch request code if your Activity under test calls startActivityForResult(Intent, int).

boolean isFinishCalled()

This method will notify you if the Activity under test called finish(), finishFromChild(Activity), or finishActivity(int).

void setActivityContext(Context activityContext)

If you wish to inject a Mock, Isolated, or otherwise altered context, you can do so here.

void setApplication(Application application)

Set the application for use during the test.

Protected methods

void setUp()

Sets up the fixture, for example, open a network connection.

T startActivity(Intent intent, Bundle savedInstanceState, Object lastNonConfigurationInstance)

Start the activity under test, in the same way as if it was started by Context.startActivity(), providing the arguments it supplied.

void tearDown()

Make sure all resources are cleaned up and garbage collected before moving on to the next test.

Public constructors

ActivityUnitTestCase

Added in API level 1
ActivityUnitTestCase (Class<T> activityClass)

Parameters
activityClass Class

Public methods

getActivity

Added in API level 1
T getActivity ()

Returns
T Returns the activity under test.

getFinishedActivityRequest

Added in API level 1
int getFinishedActivityRequest ()

This method will return the request code if the Activity under test called finishActivity(int).

Returns
int The request code provided in the start call, or -1 if no finish call was made.

getRequestedOrientation

Added in API level 1
int getRequestedOrientation ()

This method will return the value if your Activity under test calls setRequestedOrientation(int).

Returns
int

getStartedActivityIntent

Added in API level 1
Intent getStartedActivityIntent ()

This method will return the launch intent if your Activity under test calls startActivity(Intent) or startActivityForResult(Intent, int).

Returns
Intent The Intent provided in the start call, or null if no start call was made.

getStartedActivityRequest

Added in API level 1
int getStartedActivityRequest ()

This method will return the launch request code if your Activity under test calls startActivityForResult(Intent, int).

Returns
int The request code provided in the start call, or -1 if no start call was made.

isFinishCalled

Added in API level 1
boolean isFinishCalled ()

This method will notify you if the Activity under test called finish(), finishFromChild(Activity), or finishActivity(int).

Returns
boolean Returns true if one of the listed finish methods was called.

setActivityContext

Added in API level 1
void setActivityContext (Context activityContext)

If you wish to inject a Mock, Isolated, or otherwise altered context, you can do so here. You must call this function before calling startActivity(Intent, Bundle, Object). If you wish to obtain a real Context, as a building block, use getInstrumentation().getTargetContext().

Parameters
activityContext Context

setApplication

Added in API level 1
void setApplication (Application application)

Set the application for use during the test. You must call this function before calling startActivity(Intent, Bundle, Object). If your test does not call this method,

Parameters
application Application: The Application object that will be injected into the Activity under test.

Protected methods

setUp

Added in API level 1
void setUp ()

Sets up the fixture, for example, open a network connection. This method is called before a test is executed.

Throws
Exception

startActivity

Added in API level 1
T startActivity (Intent intent, 
                Bundle savedInstanceState, 
                Object lastNonConfigurationInstance)

Start the activity under test, in the same way as if it was started by Context.startActivity(), providing the arguments it supplied. When you use this method to start the activity, it will automatically be stopped by tearDown().

This method will call onCreate(), but if you wish to further exercise Activity life cycle methods, you must call them yourself from your test case.

Do not call from your setUp() method. You must call this method from each of your test methods.

Parameters
intent Intent: The Intent as if supplied to startActivity(Intent).
savedInstanceState Bundle: The instance state, if you are simulating this part of the life cycle. Typically null.
lastNonConfigurationInstance Object: This Object will be available to the Activity if it calls getLastNonConfigurationInstance(). Typically null.
Returns
T Returns the Activity that was created

tearDown

Added in API level 1
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
Exception
