简易覆盖率信息收集框架

将emma插桩命令集成到hudson中，每当hudson完成应用程序部署自动对相应应用jar包插桩产生coverage.em文件，由于需要远程收集覆盖率信息，并且需要定时收集覆盖率信息，为了方便使用emma,本人利用spring和quartz写了一个简易的定时框架用来收集远程机器上的coverage.ec并生成报告。现将代码附上:

spring applicationContext.xml文件内容如下：

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN//EN" "http://www.springframework.org/dtd/spring-beans.dtd">

job代码如：

        //此方法用于收集覆盖率信息
public void collectTheCoverageInfo() throws IOException {
logger.info("start collecting the coverage info!");
SimpleDateFormat dateFormat = new SimpleDateFormat(
"yyyyMMddHHmmss");
String dirName = dateFormat.format(new Date()).toString();
File file = new File(coverageEcDirectory + "\\" + dirName);
file.mkdirs();
path = file.getAbsolutePath();
System.out.println(path);
String cmd = String.format(
"java emma ctl -connect %s:47653 -command coverage.get,%s\\%s",
remoteIp, path, coverageEcDirectoryFilename);
execute(cmd);
}

       //此方法用于产生测试报告
public void generatorReport() {
logger.info("start generator coverage report!");
String cmd = String
.format("java emma report -r %s -in %s,%s -Dreport.html.out.file=%s\\%s",
reportType, coverageEm, path + "\\"
+ coverageEcDirectoryFilename, path,
coverageFilename);
execute(cmd);
}

       //此方法先执行覆盖率收集然后产生报告
public void collectAndGeneratorCoverageReport() {
try {
collectTheCoverageInfo();
} catch (IOException e) {
// TODO Auto-generated catch block
System.out.println(e.getMessage());
}
generatorReport();
}

       //此方法为执行cmd命令
private void execute(String cmd) {
try {
logger.info("start execute command: " + cmd);
Process p = Runtime.getRuntime().exec(cmd);
InputStream out = p.getInputStream();
StringBuffer stringBuffer = new StringBuffer();
readOutput(out, stringBuffer);
logger.info("The output of command: " + stringBuffer);
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}


private void readOutput(InputStream input, StringBuffer buffer) {
try {
int c;
while ((c = input.read()) != -1)
buffer.append((char) c);
} catch (Exception e) {
e.printStackTrace();
}
}

commad配置文件如下所示：

   #对应项目名称,该字段暂时无用
Emma.ProjectDirectory=F:\项目\保理
#coverage.ec文件存放文件夹
Emma.CoverageEcOutPutDirectory=F:\\TestFile
#ec文件的命名
Emma.CoverageEcOutPutDirectoryFilename=coverage.ec
#report存放文件夹
Emma.CoverageReportDirectory=F:\\TestFile
#report文件名
Emma.CoverageReportDirectoryFilename=coverage
#需要收集的远程服务ip
Emma.RemotePcIp=10.132.97.58
#em文件存放位置
Emma.CoverageEmDirectoryFilename=F:\\TestFile\\creditcore_coverage.em
#report产生类型，可以支持xml,txt,html
Emma.ReportType=html
#定时执行时间cron表达式
Emma.TaskTime=0 53 19 ? * *
