Android测试框架初步

一、实验目的

1．掌握android测试项目的建立

2．掌握android测试框架的基本内容

3．编写运行android测试

二、实验内容与步骤

建立android项目MyProject，运行截图如下：

l  点击ok按钮，EditText内字母变大写

l  点击超链接，打开浏览器上网

请用知识对本项目进行测试，要求：

1、对组件进行对齐测试（assertOnScreen和assertRightAligned方法）

2、对EditText进行传值测试（使用sendKeys 和 sendRepeatedKeys两种方法）

3、对Button进行功能测试（performClick和sendKeys方法）

4、对超链接进行测试（ActivityMonitor内部类）

5、为了保证测试的完整性和准确性，请适当添加必要的功能（如先决条件，多种方法等）

注：建立android测试项目过程如下

1、新建android测试项目

2、建立好测试项目之后，在测试项目中的src目录下，右键点击你创建的包，依次选择新建—>JUnit Test Case，弹出如下界面：
