Ngrinder脚本编写主要使用方法

Ngrinder脚本 groovy

1、生成随机字符串(import org.apache.commons.lang.RandomStringUtils)

  数字:RandomStringUtils.randomNumeric(length);

  字母:RandomStringUtils.randomAlphabetic(length);

  字母加数字:RandomStringUtils.randomAlphanumeric(length);

  所有ASCCII字符:RandomStringUtils.randomAscii(length);

   自定义混合字符:RandomStringUtils.randomAscii(length, string);

2、生成随机数字:(import java.util.concurrent.ThreadLocalRandom;)

  数字:int random_number = ThreadLocalRandom.current().nextInt(min_num, max_num);
     
3、获取项目数据文件路径:
  common项目:"/resources/account.txt"
  maven项目:Thread.currentThread().getContextClassLoader().getResource("/account.txt").getPath();
  maven项目获取文件内容:ReflectionUtils.getCallingClass(0).getResourceAsStream("/account.txt").getText("UTF-8")

4、读取文件:

   txt每行单数据:String[] file_arrary = new File("/resources/account.txt"as String[];

           String file_data = file_arrary[arrary_index];

   txt每行双数据:String[] file_arrary = new File("/resources/account.txt"as String[];

           String data_one = file_arrary[arrary_index].split(",")[0];
                String data_two = file_arrary[arrary_index].split(",")[1];
        另一种方法:     
                 List<String> reqDataArrList = new File(dataFilePath).readLines()
                 String data_one = reqDataArrList.get(arrary_index).split(",")[0];
                 String data_two = reqDataArrList.get(arrary_index).split(",")[1];
  txt每行多数据可参考双数据方法。也可以参考json方式存储:
                 BufferedReader txt_content=new BufferedReader(new FileReader(new File("/resources/account.txt")))
                                    data_json = new JSONObject()
                                    String text_line = ""
                                    while(( text_line=txt_content.readLine())!=null){
                                        data_json.put(text_line.split(",")[0],text_line.split(",")[1])
                                    }
                                    String data_one = data_json.keys[0]
                                    String data_two = data_json.getString(data_one)
 
5、写入文件:
   覆盖写入:def write new File(file_path, file_name).newPrintWriter();
                            write.write(write_text);
                            write.flush();
                            write.close()
                             
   追加写入:def write new File(file_path, file_name).newPrintWriter();
                            write.append(write_text);
                            write.flush();
                            write.close()
6、json文件的数据处理(import org.ngrinder.recorder.RecorderUtils)
   json文件读取:String json_str = new File(file_path).getText("UTF-8")
                            def json_object = RecorderUtils.parseRequestToJson(json_str)
                       长度:json_object.length()
                       关键字:json_object.keys()
                       添加元素:json_object.put(name, value)
                       修改元素:json_object.put(name, value)
                       删除元素:json_object.remove(name, value)
                       获取对应value:json_object.getString(name)

 

7、字符串的处理
        字符串截取:String new_str = old_str[0..3]
        字符串替换:String string = str.replace("old","new")
        字符串统计:int count = string.count("char")
        字符串转化:int int_num = Integer.parseInt(string)
8、设置多个请求事务(即多个test方法)
        1)设置多个静态Gtest对象:
            public static GTest test1
            public static GTest test2
        2)实例化多个Gtest对象:
            test1 = new GTest(1"test1");
            test2 = new GTest(2"test2");
        3)监听多个test请求:
            test1.record(this, "test1")
            test2.record(this, "test2")
        4)定义多个test方法:
            public void test1(){
                grinder.logger.info("---ones: {}---", grinder.threadNumber+1)
            }
            public void test2(){
                grinder.logger.info("---twos: {}---", grinder.threadNumber+1)
            }
9、Ngrinder定义请求参数集:
        add方法:List<NVPair> paramList = new ArrayList<NVPair>();
                    paramList.add(new NVPair("name""value"));
                    paramList.add(new NVPair("name""value"));
                    params = paramList.toArray();              
        new方法:params = [new NVPair("name""value"), new NVPair("name""value")];
10、Ngrinder处理日志:
        日志级别(三种常见) grinder.logger.info("----before process.----");
         grinder.logger.warn("----before process.----");
         grinder.logger.error("----before process.----");                                 
        日志限定(仅打印error级别) :1)导入依赖包
                                  import ch.qos.logback.classic.Level;
                                  import org.slf4j.LoggerFactory;
                                 2)设定级别
                                    @BeforeThread
                                     LoggerFactory.getLogger("worker").setLevel(Level.ERROR);
                                  3)设置打印语句
                                    @test
                                    grinder.logger.error("----error.----");
        日志输出(输出所有进程日志):将每个agent的.ngrinder_agent/agent.conf中一项修改为agent.all_logs=true
        日志打印:打印变量:grinder.logger.error("{},{}",variable1,variable2); // 换行或缩进可在""中加\n或\t
11、Ngrinder的cookie处理
        1) 登录产生cookie
            @BeforeThread
                login_get_cookie(); // 调用登录方法
                cookies = CookieModule.listAllCookies(HTTPPluginControl.getThreadHTTPClientContext()); // 配置cookie管理器
        2) 读取控制器中cookie
            @Before
                cookies.each { CookieModule.addCookie(it, HTTPPluginControl.getThreadHTTPClientContext()) }
12、Ngrinder请求方式:
        1)通过url加参数直接访问:
            post方法: HTTPResponse result = request.POST("http://192.168.2.135:8080/blogs", params, headers)
            get方法:  HTTPResponse result = request.GET("http://192.168.2.135:8080/blogs", params, headers)
            参数是json:设置请求头参数{"Content-Type""application/json"}
        2)通过参数化所有请求数据为json对象(导入import org.ngrinder.recorder.RecorderUtils)
                            HTTPResponse result = RecorderUtils.sendBy(request, req_data_json)
                            HTTPResponse result = RecorderUtils.sendBy(request, req_data_json)
13、Ngringer的test运行次数设定(将总运行测试次数按百分比例分配到相应test):
        1)引用依赖包:
            import net.grinder.scriptengine.groovy.junit.annotation.RunRate
        2)设置运行次数百分比(所有test设定的比例值不够100,那不满的部分不运行,比如设定总比80,只运行这80部分):
            @RunRate(50)  // 数字代表百分比
            @Test
            public void test1(){}
            @RunRate(50)  // 数字代表百分比
            @Test
            public void test2(){}
14、Ngringer获取设置的加压机总数、进程总数、线程总数等信息:
        int tota_agents = Integer.parseInt(grinder.getProperties().get("grinder.agents").toString()) // 设置的总加压机数
        int total_processes = Integer.parseInt(grinder.properties().get("grinder.processes").toString()) // 设置的总进程数
        int total_threads = Integer.parseInt(grinder.properties().get("grinder.threads").toString()) // 设置的总线程数
        int total_runs = Integer.parseInt(grinder.properties().get("grinder.runs").toString()) // 设置的总运行次数(若设置的是运行时长,则得到0)
15、Ngringer获取当前运行的加压机编号、进程编号、线程编号等信息(都从0递增):
        int agent_number = grinder.agentNumber // 当前运行的加压机编号
        int process_number = grinder.processNumber // 当前运行的进程编号
        int thread_number = grinder.threadNumber // 当前运行的线程编号
        int run_number = grinder.runNumber // 当前运行的运行次数编号
         
16、Ngringer获取唯一递增值方法(从1递增,不重复):
        // 传递接口参数runNumber(即def runNumber = grinder.runNumber)
        private int getIncrementId(int runNumber){
            // 获取压力机总数、进程总数、线程总数
            int totalAgents = Integer.parseInt(grinder.getProperties().get("grinder.agents").toString())
            int totalProcess = Integer.parseInt(grinder.getProperties().get("grinder.processes").toString())
            int totalThreads = Integer.parseInt(grinder.getProperties().get("grinder.threads").toString())
             
            // 获取当前压力机数、进程数、线程数
            int agentNum = grinder.agentNumber
            int processNum = grinder.processNumber
            int threadNum = grinder.threadNumber
             
            // 获取唯一递增数id
            int incrementId = agentNum * totalProcess * totalThreads + processNum * totalThreads + threadNum + totalAgents * totalProcess * totalThreads * runNumber
            return incrementId
        }
17、Ngringer根据唯一递增值获取参数化文件中的唯一行号:
        1)需要设置静态变量:private enum WhenOutOfValues { AbortVuser, ContinueInCycleManner, ContinueWithLastValue }
        2)传递接口参数fileDataList(即def fileDataList = new File(dataFilePath).readLines())
        private int getLineNum(def fileDataList) {
            // 获取当前运行数、数据读取行数、数据最大行数
            int counter = getIncrementId(grinder.runNumber)
            int lineNum = counter + 1
            int maxLineNum = fileDataList.size() - 1
             
            // 读取最大值的判断处理
            WhenOutOfValues outHandler = WhenOutOfValues.AbortVuser
            if (lineNum > maxLineNum) {
                 if(outHandler.equals(WhenOutOfValues.AbortVuser)) {
                    lineNum = maxLineNum //grinder.stopThisWorkerThread()
                 else if (outHandler.equals(WhenOutOfValues.ContinueInCycleManner)) {
                    lineNum = (lineNum - 1) % maxLineNum + 1
                 else if (outHandler.equals(WhenOutOfValues.ContinueWithLastValue)) {
                     lineNum = maxLineNum
                 }
            }
            return lineNum
        }
18、Ngrinder日志输出配置的测试信息:(import java.text.SimpleDateFormat)
        public static String getTestInfo(){
            String time_string = ""
            // 获取压测时设置的进程总数、线程总数、运行次数并在log中打印
            int all_process = grinder.getProperties().getInt("grinder.processes"1// 设置的总进程数
            int all_threads = grinder.getProperties().getInt("grinder.threads"1)  // 设置的总线程数
            int all_runs = grinder.getProperties().getInt("grinder.runs"1)  // 设置的总运行次数(若设置的是运行时长,则得到0)
            int all_duration = grinder.getProperties().getLong("grinder.duration"1// 设置的总运行时长(若设置的是运行次数,则得到0)
            // 格式化时间毫秒输出(输出格式00:00:00)
            SimpleDateFormat formatter = new SimpleDateFormat("HH:mm:ss")
            formatter.setTimeZone(TimeZone.getTimeZone("GMT+00:00"))
            String all_duration_str = formatter.format(all_duration)
            if (all_duration_str.equals("00:00:00"))
                time_string = "Test information: the processes is "+all_process+", the threads is "+all_threads+", the run count is "+all_runs+"."
            else
                time_string = "Test information: the processes is "+all_process+", the threads is "+all_threads+", the run time is "+all_duration_str+"."
            return time_string
        }
19、Ngrinder打印所有的配置信息
            String property = grinder.getProperties();
            grinder.logger.info("------- {}"property) ;
 
20、Ngrinder获取请求返回值:
            HTTPResponse result = request.POST("http://192.168.2.135:8080/blogs", params, headers)
            返回的文本:grinder.logger.info("----{}----", result.getText()) // 或者result.text
            返回的状态码:grinder.logger.info("----{}----", result.getStatusCode()) // 或者result.statusCode
            返回的url:grinder.logger.info("----{}----", result.getEffectiveURI())
            返回的请求头所有参数:grinder.logger.info("---\n{}---", result)
            返回的请求头某参数:grinder.logger.info("----{}---- ", result.getHeader("Content-type"))
             
21、Ngrinder返回值的匹配:
    匹配状态码:assertThat(result.getStatusCode(), is(200))
    匹配包含文本:assertThat(result.getText(), containsString("success"))
             
22、Ngrinder获取所有虚拟用户数:
    public int getVusers() {
        int totalAgents = Integer.parseInt(grinder.getProperties().get("grinder.agents").toString());
        int totalProcesses = Integer.parseInt(grinder.getProperties().get("grinder.processes").toString());
        int totalThreads = Integer.parseInt(grinder.getProperties().get("grinder.threads").toString());
        int vusers = totalAgents * totalProcesses * totalThreads;
        return vusers;
    }
23、Ngrinder的断言和error日志输出
    if (result.statusCode == 301 || result.statusCode == 302) {
            grinder.logger.error("Possible error: {} expected: <200> but was: <{}>.",result.getEffectiveURI(),result.statusCode);
        else {
            assertEquals((String)result.getEffectiveURI(), result.statusCode, 200)
            assertThat((String)result.getEffectiveURI(), result.statusCode, is(200))
        }
