如何进行Android单元测试

1、Menifest.xml 中加入：
   <application> 中加入：

   view plaincopy to clipboardprint?
<uses-library android:name="android.test.runner" /> 
<uses-library android:name="android.test.runner" />

   <application> 外面加入：

   view plaincopy to clipboardprint?
<uses-permission android:name="android.permission.RUN_INSTRUMENTATION" /> 
<instrumentation android:name="android.test.InstrumentationTestRunner" android:targetPackage="name.feisky.android.test" 
android:label="Test for my app"/>  
<uses-permission android:name="android.permission.RUN_INSTRUMENTATION" />
<instrumentation android:name="android.test.InstrumentationTestRunner" android:targetPackage="name.feisky.android.test"
android:label="Test for my app"/> 

2、 编写单元测试代码：必须继承自 AndroidTestCase 类

   view plaincopy to clipboardprint?
package name.feisky.android.test;  
     
import android.test.AndroidTestCase;  
import junit.framework.Assert;  
     
public class MyTest extends AndroidTestCase {  
private static final String Tag="MyTest";  
     
public void testSave() throws Throwable  
{  
int i=4+8;  
Assert.assertEquals(5,i);  
}  
     
public void testSomethingElse() throws Throwable {  
Assert.assertTrue(1 + 1 == 12);  
}  
     
}  
package name.feisky.android.test;
  
import android.test.AndroidTestCase;
import junit.framework.Assert;
  
public class MyTest extends AndroidTestCase {
private static final String Tag="MyTest";
  
public void testSave() throws Throwable
{
int i=4+8;
Assert.assertEquals(5,i);
}
  
public void testSomethingElse() throws Throwable {
Assert.assertTrue(1 + 1 == 12);
}
  
} 

3、 执行测试

   IntelliJ 中：

   eclipse 中：右键 run as Android JUnit Test

   命令行工具：

   view plaincopy to clipboardprint?
adb shell am instrument -w name.feisky.android.test/android.test.InstrumentationTestRunner  
adb shell am instrument -w name.feisky.android.test/android.test.InstrumentationTestRunner 

也可以新建一个测试项目进行测试

1、 New  > Project  > Android  > Android Test Project .

添加测试用例类
添加新类，基类设置为 android.test.ActivityInstrumentationTestCase2<HelloAndroid>

添加构造函数
添加 setUp() 方法，这个方法在所有的测试之前进行变量和测试环境的初始化。

view plaincopy to clipboardprint?
@Override 
    protected void setUp() throws Exception {  
        super.setUp();  
        mActivity = this.getActivity();  
        mView = (TextView) mActivity.findViewById(com.example.helloandroid.R.id.textview);  
        resourceString = mActivity.getString(com.example.helloandroid.R.string.hello);  
    }  
@Override
    protected void setUp() throws Exception {
        super.setUp();
        mActivity = this.getActivity();
        mView = (TextView) mActivity.findViewById(com.example.helloandroid.R.id.textview);
        resourceString = mActivity.getString(com.example.helloandroid.R.string.hello);
    } 
添加testPreconditions () 方法，检查初始化环境，只执行一次
view plaincopy to clipboardprint?
public void testPreconditions() {  
      assertNotNull(mView);  
    }  
public void testPreconditions() {
      assertNotNull(mView);
    } 
添加单元测试
view plaincopy to clipboardprint?
public void testText() {  
      assertEquals(resourceString,(String)mView.getText());  
    }  
public void testText() {
      assertEquals(resourceString,(String)mView.getText());
    }
