Robotium自动化测试利用InstrumentationTestRunner和XmlSerializer导出xml报告到手机里

用Robotium有一段时间了，下面说一下，利用这个框架把报告导入手机里，因为项目要求不能用Eclipse，只能用adb命令实现，可以先用开发工具生成测试工程的apk，安装到手机里，直接用命令运行，再用命令把报告pull到pc端就OK了，最好再集成到Hudson上面，就能获得更好的客户体验了，Robotium的知识不再所说，看到这篇文章的基本都懂吧，Robotium框架是不会自动生成报告到手机里的，所以要修改一下InstrumentationTestRunner类，这是单元测试的基础吧，在测试工程了新建一个InstrumentationTestRunner类，具体代码如下：

[java] view
plaincopy

import android.os.Bundle;

import android.os.Environment;

import java.io.File;

import java.io.FileWriter;

import java.io.IOException;

import java.io.Writer;

import java.text.SimpleDateFormat;

import java.util.Date;

import org.xmlpull.v1.XmlPullParserFactory;

import org.xmlpull.v1.XmlSerializer;

public class InstrumentationTestRunner extends

android.test.InstrumentationTestRunner {

private Writer mWriter;

private XmlSerializer mTestSuiteSerializer;

private long mTestStarted;

public void onStart() {

try {

Date d = new Date();

SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd-kk-mm");

String strTime = sdf.format(d);

String xmlName = "Test" + strTime + ".xml";

// 如果被测的应用本身有读写sdcard权限的话级可以直接放在sdcard里面，否则机会失败，

// 有测试应用源码的情况下是可以在AndroidManifest.xml里添加权限，当然所数情况下是没有源码的，

// 只能放在被测应用的files目录里了，这个是不需要权限的

// String SDPath = Environment.getExternalStorageDirectory() + "/";

// String logPath = SDPath + "TestLog/";

// File file = new File(logPath);

// if (file.exists()) {

// } else {

// file.mkdirs();

// }

// startJUnitOutput(new FileWriter(new File(file, xmlName)));

startJUnitOutput(new FileWriter(new File(getTargetContext()

.getFilesDir(), xmlName)));

} catch (IOException e) {

throw new RuntimeException(e);

}

super.onStart();

}

void startJUnitOutput(Writer writer) {

try {

this.mWriter = writer;

this.mTestSuiteSerializer = newSerializer(this.mWriter);

this.mTestSuiteSerializer.startDocument(null, null);

this.mTestSuiteSerializer.startTag(null, "testsuites");

this.mTestSuiteSerializer.startTag(null, "testsuite");

} catch (Exception e) {

throw new RuntimeException(e);

}

}

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);

}

}

public void sendStatus(int resultCode, Bundle results) {

super.sendStatus(resultCode, results);

switch (resultCode) {

case -2:

case -1:

case 0:

try {

recordTestResult(resultCode, results);

} catch (IOException e) {

throw new RuntimeException(e);

}

case 1:

recordTestStart(results);

}

}

void recordTestStart(Bundle results) {

this.mTestStarted = System.currentTimeMillis();

}

void recordTestResult(int resultCode, Bundle results) throws IOException {

float time = (float) (System.currentTimeMillis() - this.mTestStarted) / 1000.0F;

String className = results.getString("class");

String testMethod = results.getString("test");

String stack = results.getString("stack");

int current = results.getInt("current");

int total = results.getInt("numtests");

this.mTestSuiteSerializer.startTag(null, "testcase");

this.mTestSuiteSerializer.attribute(null, "ID", current + "");

this.mTestSuiteSerializer.attribute(null, "classname", className);

this.mTestSuiteSerializer.attribute(null, "casename", testMethod);

// Log.v("myInfor", current + "");

if (resultCode != 0) {

this.mTestSuiteSerializer

.attribute(

null,

"time",

String.format("%.3f",

new Object[] { Float.valueOf(time) }));

this.mTestSuiteSerializer.startTag(null, "result");

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);

}

this.mTestSuiteSerializer.attribute(null, "message", message);

// this.mTestSuiteSerializer.attribute(null, "type", reason);

// this.mTestSuiteSerializer.text(stack);

this.mTestSuiteSerializer.text("failure");

}

this.mTestSuiteSerializer.endTag(null, "result");

} else {

this.mTestSuiteSerializer

.attribute(

null,

"time",

String.format("%.3f",

new Object[] { Float.valueOf(time) }));

this.mTestSuiteSerializer.startTag(null, "result");

this.mTestSuiteSerializer.attribute(null, "message", "pass");

this.mTestSuiteSerializer.text("success");

this.mTestSuiteSerializer.endTag(null, "result");

}

this.mTestSuiteSerializer.endTag(null, "testcase");

if (current == total) {

// this.mTestSuiteSerializer.startTag(null, "system-out");

// this.mTestSuiteSerializer.endTag(null, "system-out");

// this.mTestSuiteSerializer.startTag(null, "system-err");

// this.mTestSuiteSerializer.endTag(null, "system-err");

this.mTestSuiteSerializer.endTag(null, "testsuite");

this.mTestSuiteSerializer.flush();

}

}

public void finish(int resultCode, Bundle results) {

endTestSuites();

super.finish(resultCode, results);

}

void endTestSuites() {

try {

this.mTestSuiteSerializer.endTag(null, "testsuites");

this.mTestSuiteSerializer.endDocument();

this.mTestSuiteSerializer.flush();

this.mWriter.flush();

this.mWriter.close();

} catch (IOException e) {

throw new RuntimeException(e);

}

}

}

这个类写好之后还要在测试工程的AndroidManifest.xml里修改一下：

[html] view
plaincopy

<instrumentation

android:name="com.和谐.test.InstrumentationTestRunner"

android:targetPackage="com.sds.android.ttpod" />

name是修改的InstrumentationTestRunner类的完整类名，targetPackage是被测试应用的包名，这是在没有源码的情况下
当然这个应用是有读写sdcard的权限的，所以上面的InstrumentationTestRunner代码可以把注释解除直接生成到sdcard里面，更加方便的adb命令pull出。有需要的朋友不理解的话，可以留言互相交流。
