android jUnit test 进行自动化测试

一. 被test的工程：

新建一个android工程：D_session；它有一个activity：D_sessionActivity；package名：com.mysession

二.测试工程：

新建一个测试工程：D_sessionTest, 类型是android test project;

1. menifest文件：

<?xml version="1.0" encoding="utf-8"?>

<manifest xmlns:android="http://schemas.android.com/apk/res/android"

package="com.mysession.test"

android:versionCode="1"

android:versionName="1.0" >

<uses-sdk android:minSdkVersion="8" />

<instrumentation

android:name="android.test.InstrumentationTestRunner"

android:targetPackage="com.mysession" />

<application

android:icon="@drawable/ic_launcher"

android:label="@string/app_name" >

<uses-library android:name="android.test.runner" />

</application>

</manifest>

2. 一个base activity 来定义各种模拟测试者的动作和判断测试结果，各个测试类都继承该类：

package com.mysession.test;

import android.app.Activity;

import android.app.Instrumentation;

import android.app.Instrumentation.ActivityMonitor;

import android.content.Intent;

import android.test.InstrumentationTestCase;

import android.test.TouchUtils;

import android.widget.Button;

import android.widget.TextView;

import com.mysession.D_sessionActivity;

public class SessionActivityTest extends InstrumentationTestCase {

private Instrumentation mInstrumentation;

private ActivityMonitor mSessionMonitor;

private Activity mCurrentActivity, mSessionActivity;

private String TextNotEqual = "text not equal.";

private static final String PackageName = "com.mysession";

@Override

protected void setUp() throws Exception {

// 初始化

super.setUp();

if (mInstrumentation == null) {

mInstrumentation = getInstrumentation();

}

mSessionActivity = null;

}

@Override

protected void tearDown() throws Exception {

super.tearDown();

//释放资源

closeActivity(mSessionActivity);

mCurrentActivity = null;

}

private void closeActivity(Activity activity) {

if(activity != null){

activity.finish();

activity = null;

}

}

public void openSessionActivity() {

// 打开session activity

try {

setUp();

} catch (Exception e) {

e.printStackTrace();

}

mSessionMonitor = mInstrumentation.addMonitor(

D_sessionActivity.class.getName(), null, false);

Intent intent = new Intent(Intent.ACTION_MAIN);

intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);

intent.setClassName(PackageName, D_sessionActivity.class.getName());

mInstrumentation.startActivitySync(intent);

mSessionActivity = getInstrumentation().waitForMonitor(mSessionMonitor);

assertNotNull(mSessionActivity);

mCurrentActivity = mSessionActivity;

}

//判断text是否正确

public void assertTextEqual(int resId, String strText) {

TextView textView = (TextView) mCurrentActivity.findViewById(resId);

assertNotNull(textView);

assertEquals(TextNotEqual,

strText,

textView.getText().toString());

};

// 模拟按钮点击事件

public void clickButton(int resId){

Button button = (Button) mCurrentActivity.findViewById(resId);

assertNotNull(button);

TouchUtils.clickView(this, button);

}

}

3. 各个测试类：

测试类一：

package com.mysession.test.cases;

import com.mysession.R;

import com.mysession.test.SessionActivityTest;

public class MyCase1 extends SessionActivityTest {

public void testCase1() {

openSessionActivity();

assertTextEqual(R.id.etUrl,

"http://172.20.230.5/iportal/samples/jsapi/mobile.html");

}

public void testCase3() {

openSessionActivity();

clickButton(R.id.btnLoad);

clickButton(R.id.btnHistory);

}

}

测试类二：

package com.mysession.test.cases;

import com.mysession.R;

import com.mysession.test.SessionActivityTest;

public class MyCase2 extends SessionActivityTest{

public void testCase2() {

openSessionActivity();

clickButton(R.id.btnLoad);

}

}

三. 有些动作（如点击menu）需要通过包robotium-solo-1.8.0.jar来完成。

所以要在Build Path->Configure Build Path…中导入：robotium-solo-1.8.0.jar

程序中：

private Solo solo;

solo = new Solo(getInstrumentation(),getActivity);

就可以使用solo了， 如：

solo.clickOnMenuItem(text);

solo.goBack();
