android 单元测试

首先AndroidManifest.xml

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.travelsky.test" android:versionCode="1"
    android:versionName="1.0">
    <uses-sdk android:minSdkVersion="3" />
    <uses-permission android:name="android.permission.RUN_INSTRUMENTATION" />
    <instrumentation android:name="android.test.InstrumentationTestRunner"
        android:targetPackage="com.travelsky.test" android:label="Test for my app" />
    <application android:icon="@drawable/icon" android:label="@string/app_name">
        <uses-library android:name="android.test.runner" />
        <activity android:name=".AndroidTestActivity" android:label="@string/app_name">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />
                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>

    </application>
</manifest>

添加

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

<instrumentation android:name="android.test.InstrumentationTestRunner"
        android:targetPackage="com.travelsky.test" android:label="Test for my app" />

编写单元测试代码：

package com.travelsky.test;

import android.app.Activity;
import android.test.ActivityInstrumentationTestCase2;
import android.widget.TextView;

public class Testa extends ActivityInstrumentationTestCase2 {
    Activity mActivity = null;
    TextView mView = null;

    public Testa() {
        super("com.travelsky.test", AndroidTestActivity.class);
        // TODO Auto-generated constructor stub
    }

    @Override
    protected void setUp() throws Exception {

        super.setUp();

        mActivity = this.getActivity();
        mView = (TextView) mActivity.findViewById(com.travelsky.test.R.id.tv);

    }

    public void testPreconditions() {
        assertNotNull(mView);
    }

    @Override
    protected void tearDown() throws Exception {
        // TODO Auto-generated method stub
        super.tearDown();
    }

}

run
