Java的单元测试JUnit。
Java程序入口是main方法。一般不在安卓程序入口
@Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); }
做测试。
package com.itheima.test; import android.test.AndroidTestCase; public class MyMathTest extends AndroidTestCase { public void testAdd(){ MyMath math = new MyMath(); int result = math.add(3, 4); assertEquals(7, result);//断言,前面是期望值,后面是实际值 } }
这是一个安卓的应用，最终想测试这个方法，必须得把代码跑到设备上才行。代码得跑在ARM/Dalvik虚拟机才行。所以首先要把代码部署到设备上。

[2017-06-13 07:19:33 - Day03_01_android单元测试] ------------------------------
[2017-06-13 07:19:33 - Day03_01_android单元测试] Android Launch!
[2017-06-13 07:19:33 - Day03_01_android单元测试] adb is running normally.
[2017-06-13 07:19:33 - Day03_01_android单元测试] Day03_01_android单元测试 does not specify a android.test.InstrumentationTestRunner instrumentation or does not declare uses-library android.test.runner in its AndroidManifest.xml
必须在清单文件里面指定一个仪器设备instrumentation a android.test.InstrumentationTestRunner
<instrumentation android:name="android.test.InstrumentationTestRunner" android:targetPackage="com.itheima.test"></instrumentation>
<uses-sdk android:minSdkVersion="8" android:targetSdkVersion="17" /> <instrumentation android:name="android.test.InstrumentationTestRunner" android:targetPackage="com.itheima.test"></instrumentation> <application android:allowBackup="true" android:icon="@drawable/ic_launcher" android:label="@string/app_name" android:theme="@style/AppTheme" > <uses-library android:name="android.test.runner"/>
指定了测试要用到的仪器<instrumentation android:name="android.test.InstrumentationTestRunner" android:targetPackage="com.itheima.test"></instrumentation>，还有测试所要依赖的库<uses-library android:name="android.test.runner"/>。
这个代码一定要在安卓的虚拟机下执行。PC机上是没有安卓设备的。所以一定要把它部署到一个安卓设备上，才能够测试安卓项目里面的代码。
