改进了几个点
不用借助 Instrumentation 启动，正常启动即可；
测试代码不用 push 到主分支，主分支代码拉到本地后用 git apply patch 方式合并覆盖率代码；
测试完成后，连按两次 back 键把 app 置于后台，并自动上报覆盖率文件到服务器；
src 下新建一个 test package，放入下面两个测试类
import android.util.Log;
import java.io.File;
import java.io.FileOutputStream;
import java.io.IOException;
import java.io.OutputStream;
/**
* Created by sun on 17/7/4.

public class JacocoUtils {
static String TAG = "JacocoUtils";
//ec文件的路径
private static String DEFAULT_COVERAGE_FILE_PATH = "/mnt/sdcard/coverage.ec";
/**
* 生成ec文件
*
* @param isNew 是否重新创建ec文件
*/
public static void generateEcFile(boolean isNew) {
// String DEFAULT_COVERAGE_FILE_PATH = NLog.getContext().getFilesDir().getPath().toString() + "/coverage.ec";
Log.d(TAG, "生成覆盖率文件: " + DEFAULT_COVERAGE_FILE_PATH);
OutputStream out = null;
File mCoverageFilePath = new File(DEFAULT_COVERAGE_FILE_PATH);
try {
if (isNew && mCoverageFilePath.exists()) {
Log.d(TAG, "JacocoUtils_generateEcFile: 清除旧的ec文件");
mCoverageFilePath.delete();
}
if (!mCoverageFilePath.exists()) {
mCoverageFilePath.createNewFile();
}
out = new FileOutputStream(mCoverageFilePath.getPath(), true);
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));
// ec文件自动上报到服务器
UploadService uploadService = new UploadService(mCoverageFilePath);
uploadService.start();
} catch (Exception e) {
Log.e(TAG, "generateEcFile: " + e.getMessage());
} finally {
if (out == null)
return;
try {
out.close();
} catch (IOException e) {
e.printStackTrace();
}
}
}
}

在 build.gradle 新增
apply plugin: 'jacoco'
jacoco {
toolVersion = '0.7.9'
}
buildTypes {
release {
// 在release下统计覆盖率信息
testCoverageEnabled = true
}
}
最重要的一行代码，加在监听设备按键的地方，如果连续 2 次点击设备 back 键，app 已置于后台，则调用生成覆盖率方法。
@Override
public boolean onKeyDown(int keyCode, KeyEvent event) {
if (keyCode == KeyEvent.KEYCODE_BACK) {
....
JacocoUtils.generateEcFile(true);
}
}
为了不影响工程代码，我这里用 git apply patch 的方式应用的上面的覆盖率代码
首先 git commit 上面的覆盖率代码
然后 git log 查看 commit
我提交覆盖率代码的 commit 是最近的一次，然后拿到上一次的 commit，并生成.patch 文件，-o 是输出目录
git format-patch 0e4c................... -o ~/Documents/jk/script/
把.patch 文件拷贝到自动打包的机器，
使用 Jenkins 自动打包，拉取最新代码后，在编译前 Execute shell 自动执行下面的命令，把覆盖率文件应用到工程内
git apply --reject ~/Documents/jk/script/0001-patch.patch
执行成功后的输出：
然后就可以安装包含统计覆盖率代码的测试包了，测试完后后，连按两次 back 键生成覆盖率文件并上传到服务器。
在服务器我也拉了一个 Android 工程，专门用于生成报告
主要在 build.gradle 新增
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/coverage.ec")
doFirst {
new File("$buildDir/intermediates/classes/").eachFileRecurse { file ->
if (file.name.contains('$$')) {
file.renameTo(file.path.replace('$$', '$'))
}
}
}
}
然后设备上传 ec 文件到 Android 工程的 $buildDir/outputs/code-coverage/connected 目录下，并依次执行
gradle createDebugCoverageReport
gradle jacocoTestReport
最后把 $buildDir/reports/jacoco/目录下的覆盖率报告拷贝到展现的位置
