ActivityInstrumentationTestCase2研究成果

         准备打算做一点android平台下的自动化测试，代码写好后准备进行自动化，发现自己对ActivityInstrumentationTestCase2还一点点都不太了解，不得已又返回来了解ActivityInstrumentationTestCase2的一些知识，以便后面更好的进行android平台下自动化框架的搭建和学习。

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 ConstructorsActivityInstrumentationTestCase2(String pkg, Class<T> activityClass)

This constructor is deprecated. use ActivityInstrumentationTestCase2(Class) instead

ActivityInstrumentationTestCase2(Class<T> activityClass)

Creates an ActivityInstrumentationTestCase2.

Public MethodsTgetActivity()

Get the Activity under test, starting it if necessary.

voidsetActivityInitialTouchMode(boolean initialTouchMode)

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

voidsetActivityIntent(Intent i)

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

Protected MethodsvoidrunTest()

Runs the current unit test.

voidsetUp()

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

voidtearDown()

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

pkgignored - no longer in use.activityClassThe 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

activityClassThe 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

initialTouchModetrue 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

iThe 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
