ActivityInstrumentationTestCase2研究成果

         準備打算做一點android平臺下的自動化測試，代碼寫好後準備進行自動化，發現自己對ActivityInstrumentationTestCase2還一點點都不太瞭解，不得已又返回來了解ActivityInstrumentationTestCase2的一些知識，以便後面更好的進行android平臺下自動化框架的搭建和學習。

public abstract class

ActivityInstrumentationTestCase2

extends ActivityTestCase

java.lang.Object
↳	junit.framework.Assert
	↳	junit.framework.TestCase
		↳	android.test.InstrumentationTestCase
			↳	android.test.ActivityTestCase
				↳	android.test.ActivityInstrumentationTestCase2<T extends android.app.Activity>

Class Overview

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 UiThreadTest).
• You can inject custom Intents into your Activity (see setActivityIntent(Intent)).

This class replaces ActivityInstrumentationTestCase, which is deprecated. New tests should be written using this base class.

If you prefer an isolated unit test, see ActivityUnitTestCase.

Summary

Public Constructors
	ActivityInstrumentationTestCase2(String pkg, Class<T> activityClass) This constructor is deprecated. use ActivityInstrumentationTestCase2(Class) instead
	ActivityInstrumentationTestCase2(Class<T> activityClass) Creates an ActivityInstrumentationTestCase2.

Public Methods
T	getActivity() Get the Activity under test, starting it if necessary.
void	setActivityInitialTouchMode(boolean initialTouchMode) Call this method before the first call to getActivity() to set the initial touch mode for the Activity under test.
void	setActivityIntent(Intent i) Call this method before the first call to getActivity() to inject a customized Intent into the Activity under test.

Protected Methods
void	runTest() Runs the current unit test.
void	setUp() Sets up the fixture, for example, open a network connection.
void	tearDown() Make sure all resources are cleaned up and garbage collected before moving on to the next test.

Public Constructors

public ActivityInstrumentationTestCase2 (String pkg, Class<T> activityClass)

Since: API Level 3

This constructor is deprecated.
use ActivityInstrumentationTestCase2(Class) instead

Creates an ActivityInstrumentationTestCase2.

Parameters

pkg	ignored - no longer in use.
activityClass	The activity to test. This must be a class in the instrumentation targetPackage specified in the AndroidManifest.xml

public ActivityInstrumentationTestCase2 (Class<T> activityClass)

Since: API Level 8

Creates an ActivityInstrumentationTestCase2.

Parameters

activityClass	The activity to test. This must be a class in the instrumentation targetPackage specified in the AndroidManifest.xml

Public Methods

public T getActivity ()

Since: API Level 3

Get the Activity under test, starting it if necessary. For each test method invocation, the Activity will not actually be created until the first time this method is called.

If you wish to provide custom setup values to your Activity, you may call setActivityIntent(Intent) and/or setActivityInitialTouchMode(boolean) before your first call to getActivity(). Calling them after your Activity has started will have no effect.

NOTE: Activities under test may not be started from within the UI thread. If your test method is annotated with UiThreadTest, then your Activity will be started automatically just before your test method is run. You still call this method in order to get the Activity under test.

Returns

• the Activity under test

public void setActivityInitialTouchMode (boolean initialTouchMode)

Since: API Level 3

Call this method before the first call to getActivity() to set the initial touch mode for the Activity under test.

If you do not call this, the touch mode will be false. If you call this after your Activity has been started, it will have no effect.

NOTE: Activities under test may not be started from within the UI thread. If your test method is annotated with UiThreadTest, then you must call setActivityInitialTouchMode(boolean) fromsetUp().

Parameters

initialTouchMode	true if the Activity should be placed into "touch mode" when started

public void setActivityIntent (Intent i)

Since: API Level 3

Call this method before the first call to getActivity() to inject a customized Intent into the Activity under test.

If you do not call this, the default intent will be provided. If you call this after your Activity has been started, it will have no effect.

NOTE: Activities under test may not be started from within the UI thread. If your test method is annotated with UiThreadTest, then you must call setActivityIntent(Intent) from setUp().

The default Intent (if this method is not called) is: action = ACTION_MAIN flags = FLAG_ACTIVITY_NEW_TASK All other fields are null or empty.

Parameters

i	The Intent to start the Activity with, or null to reset to the default Intent.

Protected Methods

protected void runTest ()

Since: API Level 3

Runs the current unit test. If the unit test is annotated with UiThreadTest, force the Activity to be created before switching to the UI thread.

Throws

Throwable

protected void setUp ()

Since: API Level 3

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

Throws

Exception

protected void tearDown ()

Since: API Level 3

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
