ActivityInstrumentationTestCase2类

++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++

一.ActivityInstrumentationTestCase2类提供了单一的Activity的功能测试（基于Robotium测试框架）。

++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++

二.使用ActivityInstrumentationTestCase2类做功能测试的步骤

++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++

1.在Eclipse创建一个Andriod Test Project；

2.在该project中导入必要的类库robotium和Junit:；

jar包：robotium-solo-5.1.jar和robotium-solo-5.1-javadoc.jar

Junit4；

3.创建测试用例；

利用继承ActivityInstrumentationTestCase2类的目标Activity类，创建测试用例。

具体：继承ActivityInstrumentationTestCase2<:Activity>,在protected void setUp ()和protected void tearDown ()方法之间使用Solo对象对目标Activity进行测试用例的执行（方法）。

4.执行测试用例。

三.具体背景知识

++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++

1.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>

3.public TestDemo1() {//在构造函数处标明继承自目标项目的启动类
super(MainActivity.class);
}

2.protected void setUp ()

一些固定的设置，在执行测试之前调用此方法。

3.protected void tearDown ()

在移动到下一个测试之前确保所有的资源都被清理和垃圾收集。
