ActivityInstrumentationTestCase2

extends ActivityTestCase//继承自ActivityTestCase类

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.

-----------------------------------------------------------------------------------------------------------------------------------

该类提供单独的activity的功能测试.在测试项目下的该activity能够使用系统基类（调用： InstrumentationTestCase.launchActivity()）并且你能够直接操作你自己的Activity的。

You can run any test method on the UI thread (see UiThreadTest).//你能够在UI thread上跑任何的测试方法
You can inject custom Intents into your Activity (see setActivityIntent(Intent)).//你能够在你的Activity注入自定义的Intents(该描述意味着允许跳转)

This class replaces ActivityInstrumentationTestCase, which is deprecated. New tests should be written using this base class.//该类替代ActivityInstrumentationTestCase, 该类现在不建议使用。新的测试集应该使用该基础类。

If you prefer an isolated unit test, see ActivityUnitTestCase.//如果你更喜欢一个独立的单元测试,请参见ActivityUnitTestCase

Public Methods:

T	getActivity() Get the Activity under test, starting it if necessary.//获取在测试下的Activity，如果必要的话可以启动
void	setActivityInitialTouchMode(boolean initialTouchMode) Call this method before the first call to `getActivity()` to set the initial touch mode for the Activity under test.//在第一次调用 `getActivity()`方法前可以调用该方法去初始化测试下Activity的TOUCH模式
void	setActivityIntent(Intent i) Call this method before the first call to `getActivity()` to inject a customized Intent into the Activity under test.//在第一次调用 `getActivity()`方法前可以调用该方法去注入测试下Activity的自定义的INTENT

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.
