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());
}
测试 Run As... > Android JUnit Test
