robotium測試demo

demo是獨立app，demo和測試app同時安裝到設備上。打開demo點擊測試按鈕，開始測試。脫離開發環境，測試報告將生成xml文件，通過webview加載到demo上。

https://github.com/RobotiumTech/robotium 下載jar包 或者源碼。此demo下載源碼放入項目中，方便學習，查看。

安裝 robotium recorder。官方網址http://robotium.myshopify.com/products/robotium-recorder 。eclipse安裝 Help >? Install New Software,add添加http://recorder.robotium.com/updates

新建項目。File > New > Other > Android - Robotium Recorder

看提示 選中要測試的app項目，點擊Next > New Robotium Test，等app在設備或者虛擬機上跑起來后，就可以開始你的要測試的操作。完成后 Save > finish。Package Explorer里面會多處一個你的測試項目。先看下AndroidManifest.xml和 src下面自動生成的代碼。下面將重寫InstrumentationTestRunner 類，生成我們自己想要的xml文件。

新建在com.xxx.example類下新建InstrumentationTestRunner 繼承 android.test.InstrumentationTestRunner。

public class InstrumentationTestRunner extends android.test.InstrumentationTestRunner { private Writer mWriter; private XmlSerializer mTestSuiteSerializer; private long mTestStarted; private static final String JUNIT_XML_FILE = "TEST-REPORT.xml"; @Override public void onStart() {try{ File fileRobo = new File(getTestResultDir(getTargetContext())); if(!fileRobo.exists()){ fileRobo.mkdir(); } if(isSDCardAvaliable()){ File resultFile = new File(getTestResultDir(getTargetContext()),JUNIT_XML_FILE); startJUnitOutput(new FileWriter(resultFile)); }else{ startJUnitOutput(new FileWriter(new File(getTargetContext().getFilesDir(), JUNIT_XML_FILE))); } } catch(IOException e){ throw new RuntimeException(e); } super.onStart(); } void startJUnitOutput(Writer writer) { try { mWriter = writer; mTestSuiteSerializer = newSerializer(mWriter); mTestSuiteSerializer.startDocument(null, null); mTestSuiteSerializer.startTag(null, Tag.SUITS); mTestSuiteSerializer.startTag(null, Tag.SUIT); } catch (Exception e) { throw new RuntimeException(e); } } /** * 判斷SD卡是否存在 * @return */ private boolean isSDCardAvaliable(){ return Environment.getExternalStorageState() .equals(Environment.MEDIA_MOUNTED); } /** * 獲取測試結果報告文件所在的路徑 * @param context 被測工程的context * @return 返回測試結果報告文件所在的路徑 */ private String getTestResultDir(Context context){ String packageName = "/" + "robotium"; String filepath = context.getCacheDir().getPath() + packageName; if(android.os.Build.VERSION.SDK_INT < 8){ if(isSDCardAvaliable()){ filepath = Environment.getExternalStorageDirectory().getAbsolutePath()+ packageName; } }else{ if(isSDCardAvaliable()){ filepath = Environment.getExternalStorageDirectory().getAbsolutePath()+ packageName; } }return filepath; } private XmlSerializer newSerializer(Writer writer) { try { XmlPullParserFactory pf = XmlPullParserFactory.newInstance(); XmlSerializer serializer = pf.newSerializer(); serializer.setOutput(writer); return serializer; } catch (Exception e) { throw new RuntimeException(e); } } @Override public void sendStatus(int resultCode, Bundle results) { super.sendStatus(resultCode, results); switch (resultCode) { case REPORT_VALUE_RESULT_ERROR: case REPORT_VALUE_RESULT_FAILURE: case REPORT_VALUE_RESULT_OK: try { recordTestResult(resultCode, results); } catch (IOException e) { throw new RuntimeException(e); } break; case REPORT_VALUE_RESULT_START: recordTestStart(results); default: break; } } void recordTestStart(Bundle results) { mTestStarted = System.currentTimeMillis(); }boolean isSuccess = true;void recordTestResult(int resultCode, Bundle results) throws IOException { float time = (System.currentTimeMillis() - mTestStarted) / 1000.0f; String className = results.getString(REPORT_KEY_NAME_CLASS); String testMethod = results.getString(REPORT_KEY_NAME_TEST); String stack = results.getString(REPORT_KEY_STACK); int current = results.getInt(REPORT_KEY_NUM_CURRENT); int total = results.getInt(REPORT_KEY_NUM_TOTAL); mTestSuiteSerializer.startTag(null, Tag.SUIT); mTestSuiteSerializer.attribute(null, "classname", className);mTestSuiteSerializer.attribute(null, "name", testMethod); if (resultCode != REPORT_VALUE_RESULT_OK) { isSuccess = false;mTestSuiteSerializer.startTag(null,Tag.REASON); if (stack != null) { String reason = stack.substring(0, stack.indexOf('\n')); String message = ""; int index = reason.indexOf(':'); if (index > -1) { message = reason.substring(index+1); reason = reason.substring(0, index); } mTestSuiteSerializer.attribute(null, "message", message); mTestSuiteSerializer.attribute(null, "type", reason); mTestSuiteSerializer.text(stack); } mTestSuiteSerializer.endTag(null, Tag.REASON); } else { mTestSuiteSerializer.attribute(null,Tag.TIME, String.format("%.3f", time)); } mTestSuiteSerializer.endTag(null, Tag.SUIT); if (current == total) { mTestSuiteSerializer.endTag(null, Tag.SUIT); mTestSuiteSerializer.startTag(null, "測試結果");if(isSuccess) { mTestSuiteSerializer.text("恭喜！測試通過！"); } else {mTestSuiteSerializer.text("Sorry！請查看具體錯誤！！");}mTestSuiteSerializer.endTag(null, "測試結果");mTestSuiteSerializer.flush(); } } @Override public void finish(int resultCode, Bundle results) { endTestSuites(); Intent intent = new Intent();intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);intent.setComponent(new ComponentName("com.xxx.example.test", "com.xxx.example.test.HomeActivity"));getTargetContext().startActivity(intent);super.finish(resultCode, results);} void endTestSuites() { try { mTestSuiteSerializer.endTag(null, Tag.SUITS); mTestSuiteSerializer.endDocument(); mTestSuiteSerializer.flush(); mWriter.flush(); mWriter.close(); } catch (IOException e) { throw new RuntimeException(e); } } }注意finish時，我們重啟了我們的測試app的HomeActivity。測試報告路徑為： Environment.getExternalStorageDirectory()+"/robotium/TEST-REPORT.xml"

7.新建app的HomeActivity? 這里就添加一個Button，一個textView和webview. 在按鈕的點擊事件

Log.d("HomeActivity", "start button is onClicked!"); if(!startInstrumentation(new ComponentName(getPackageName(), getPackageName()+".InstrumentationTestRunner"), null, null)) { result.setText("啟動測試失敗"); } else {result.setText("測試中...");try { Thread.sleep(1000);} catch (InterruptedException e) { // TODO Auto-generated catch block e.printStackTrace();}HomeActivity.this.finish(); } 通過startInstrumenation來啟動測試,啟動成功退出當前activity.這里要把我們上面重寫的InstrumentationTestRunner類放在getPackageName()下。

HomeActivity的OnResume里面加載測試報告的xml文件? webView.loadUrl(path)即可。

8.配置AndroidManifest.xml? manifest下添加

<instrumentationandroid:name="com.xxx.example.test.InstrumentationTestRunner"android:targetPackage="com.xxx.example" />

application下正常配置HomeActivity額外添加?<uses-library android:name="android.test.runner" />

9.運行項目。以Android Application運行，點擊測試按鈕啟動測試。測試完成后，返回測試app并加載測試結果。

大致就是這些過程。這只是demo，正的測試還要完善xml的格式，recorder自動生成的測試用例等。自己的項目中包含公司信息，就不貼出來分享了。有什么指點或疑問，歡迎留言交流......
