Android開發之Instrumentation(自動化測試)

Android在JUnit的之外給我們又提供了Instrumentation測試架構。通過Instrumentation可以類比按鍵按下、抬起、螢幕點擊、滾動等事件，有效地控制Activity進行自動化測試。

Instrumentation是執行application instrumentation代碼的基類。當應用程式啟動並執行時候instrumentation處於開啟，Instrumentation將在任何應用程式運行前初始化，可以通過它監測系統與應用程式之間的互動。

1. Manifest.xml中描述：

<instrumentation

android:name="android.test.InstrumentationTestRunner"

android:label="Tests for My App"

android:targetPackage="com.my.test" />

<span style="font-size:18px;"><uses-permission android:name="android.permission.INJECT_EVENTS" /></span>

 

2.類比發送按鍵：

/**

     * 傳入需要的索引值即可

     * @param keyCode

     */

private void sendKeyCode(final int keyCode){ 

new Thread () { 

public void run() { 

try { 

                    Instrumentation inst = new Instrumentation(); 

                    inst.sendKeyDownUpSync(keyCode); 

                } catch (Exception e) { 

                    Log.e("Exception when sendPointerSync", e.toString()); 

                } 

            } 

        }.start(); 

    } 

}

 

3.類比滑鼠事件：

new Thread () { 

public void run () { 

try { 

                             Instrumentation inst=new Instrumentation(); 

                                     inst.sendPointerSync(MotionEvent.obtain(SystemClock.uptimeMillis(), 

                                     SystemClock.uptimeMillis(),  

                                     MotionEvent.ACTION_DOWN, 240, 400, 0)); 

                           inst.sendPointerSync(MotionEvent.obtain(SystemClock.uptimeMillis(), 

                                     SystemClock.uptimeMillis(),  

                                     MotionEvent.ACTION_UP, 240, 400, 0));   

                        } catch(Exception e) { 

                            Log.e("Exception when sendPointerSync", e.toString()); 

                        } 

                    } 

         }.start();
