背景
前段时间在研究手工测试覆盖率问题,尝试将结果记录下来。有什么问题欢迎同学指正. : )
由于现在单元测试在我们这小公司无法推行,且为了解决新功能测试以及回归测试在手工测试的情况下,即便用例再为详尽,也会存在遗漏的用例。通过统计手工测试覆盖率的数据,可以及时的完善用例。 经过了解准备使用Jacoco完成这个需求.Jacoco是Java Code Coverage的缩写,在统计完成Android代码覆盖率的时候使用的是Jacoco的离线插桩方式,在测试前先对文件进行插桩,在手工测试过程中会生成动态覆盖信息,最后统一对覆盖率进行处理,并生成报告;通过了解现在实现Android覆盖率的方法主要有两种方式,一是通过activity退出的时候添加覆盖率的统计,但是这种情况会修改app的源代码。另外一种是使用的是Android测试框架Instrumentation。这次需求的实现使用的是Instrumentation.。
实现
1. 将3个类文件放入项目test文件夹;
具体各个类的代码如下:
FinishListener:
- package 你的包名;
- public interface FinishListener {
- void onActivityFinished();
- void dumpIntermediateCoverage(String filePath);
- }
复制代码 InstrumentedActivity:
- package你的包名;
- import 你的启动的activity;
- import android.util.Log;
- public class InstrumentedActivity extends MainActivity {
- public static String TAG = "InstrumentedActivity";
- private你的包名.test.FinishListener mListener;
- public void setFinishListener(FinishListener listener) {
- mListener = listener;
- }
- @Override
- public void onDestroy() {
- Log.d(TAG + ".InstrumentedActivity", "onDestroy()");
- super.finish();
- if (mListener != null) {
- mListener.onActivityFinished();
- }
- }
- }
复制代码 JacocoInstrumentation:
- package 包名.test;
- import java.io.File;
- import java.io.FileOutputStream;
- import java.io.IOException;
- import java.io.OutputStream;
- import android.app.Activity;
- import android.app.Instrumentation;
- import android.content.Intent;
- import android.os.Bundle;
- import android.os.Looper;
- import android.util.Log;
- public class JacocoInstrumentation extends Instrumentation implements
- FinishListener {
- public static String TAG = "JacocoInstrumentation:";
- private static String DEFAULT_COVERAGE_FILE_PATH = "/mnt/sdcard/coverage.ec";
- private final Bundle mResults = new Bundle();
- private Intent mIntent;
- private static final boolean LOGD = true;
- private boolean mCoverage = true;
- private String mCoverageFilePath;
- /**
- * Constructor
- */
- public JacocoInstrumentation() {
- }
- @Override
- public void onCreate(Bundle arguments) {
- Log.d(TAG, "onCreate(" + arguments + ")");
- super.onCreate(arguments);
- DEFAULT_COVERAGE_FILE_PATH = getContext().getFilesDir().getPath().toString() + "/coverage.ec";
- File file = new File(DEFAULT_COVERAGE_FILE_PATH);
- if (!file.exists()) {
- try {
- file.createNewFile();
- } catch (IOException e) {
- Log.d(TAG, "异常 : " + e);
- e.printStackTrace();
- }
- }
- if (arguments != null) {
- mCoverageFilePath = arguments.getString("coverageFile");
- }
- mIntent = new Intent(getTargetContext(), InstrumentedActivity.class);
- mIntent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
- start();
- }
- @Override
- public void onStart() {
- if (LOGD)
- Log.d(TAG, "onStart()");
- super.onStart();
- Looper.prepare();
- InstrumentedActivity activity = (InstrumentedActivity) startActivitySync(mIntent);
- activity.setFinishListener(this);
- }
- private void generateCoverageReport() {
- Log.d(TAG, "generateCoverageReport():" + getCoverageFilePath());
- OutputStream out = null;
- try {
- out = new FileOutputStream(getCoverageFilePath(), false);
- Object agent = Class.forName("org.jacoco.agent.rt.RT")
- .getMethod("getAgent")
- .invoke(null);
- out.write((byte[]) agent.getClass().getMethod("getExecutionData", boolean.class)
- .invoke(agent, false));
- } catch (Exception e) {
- Log.d(TAG, e.toString(), e);
- } finally {
- if (out != null) {
- try {
- out.close();
- } catch (IOException e) {
- e.printStackTrace();
- }
- }
- }
- }
- private String getCoverageFilePath() {
- if (mCoverageFilePath == null) {
- return DEFAULT_COVERAGE_FILE_PATH;
- } else {
- return mCoverageFilePath;
- }
- }
- private boolean setCoverageFilePath(String filePath){
- if(filePath != null && filePath.length() > 0) {
- mCoverageFilePath = filePath;
- return true;
- }
- return false;
- }
- @Override
- public void onActivityFinished() {
- if (LOGD)
- Log.d(TAG, "onActivityFinished()");
- if (mCoverage) {
- generateCoverageReport();
- }
- finish(Activity.RESULT_OK, mResults);
- }
- @Override
- public void dumpIntermediateCoverage(String filePath){
- // TODO Auto-generated method stub
- if(LOGD){
- Log.d(TAG,"Intermidate Dump Called with file name :"+ filePath);
- }
- if(mCoverage){
- if(!setCoverageFilePath(filePath)){
- if(LOGD){
- Log.d(TAG,"Unable to set the given file path:"+filePath+" as dump target.");
- }
- }
- generateCoverageReport();
- setCoverageFilePath(DEFAULT_COVERAGE_FILE_PATH);
- }
- }
- }
复制代码 2. 修改build.gradle文件
增加Jacoco插件,打开覆盖率统计开关,生成日志报告.
添加的代码内容:
- apply plugin: 'jacoco'
- jacoco {
- toolVersion = "0.7.9"
- }
- android {
- buildTypes {
- debug { testCoverageEnabled = true
- /**打开覆盖率统计开关/
- }
- }
- def coverageSourceDirs = [
- '../app/src/main/java'
- ]
- task jacocoTestReport(type: JacocoReport) {
- group = "Reporting"
- description = "Generate Jacoco coverage reports after running tests."
- reports {
- xml.enabled = true
- html.enabled = true
- }
- classDirectories = fileTree(
- dir: './build/intermediates/classes/debug',
- excludes: ['**/R*.class',
- '**/*$InjectAdapter.class',
- '**/*$ModuleAdapter.class',
- '**/*$ViewInjector*.class'
- ])
- sourceDirectories = files(coverageSourceDirs)
- executionData = files("$buildDir/outputs/code-coverage/connected/flavors/coverage.ec")
- doFirst {
- new File("$buildDir/intermediates/classes/").eachFileRecurse { file ->
- if (file.name.contains('
- )) {
- file.renameTo(file.path.replace('
- , '
- ))
- }
- }
- }
- }
- dependencies {
- compile fileTree(dir: 'libs', include: ['*.jar'])
- }
