1、生成隨機字符串(import org.apache.commons.lang.RandomStringUtils) 數字:RandomStringUtils.randomNumeric(length); 字母:RandomStringUtils.randomAlphabetic(length); 字母加數字:RandomStringUtils.randomAlphanumeric(length); 所有ASCCII字符:RandomStringUtils.randomAscii(length); 自定義混合字符:RandomStringUtils.randomAscii(length, string); 2、生成隨機數字:(import java.util.concurrent.ThreadLocalRandom;) 數字:int random_number = ThreadLocalRandom.current().nextInt(min_num, max_num); 3、獲取項目數據文件路徑 common項目:"/resources/account.txt" maven項目:Thread.currentThread().getContextClassLoader().getResource("/account.txt").getPath(); maven項目獲取文件內容:ReflectionUtils.getCallingClass(0).getResourceAsStream("/account.txt").getText("UTF-8") 4、讀取文件: txt每行單數據: String[] file_arrary = new File("/resources/account.txt") as String[]; String file_data = file_arrary[arrary_index]; txt每行雙數據: 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]; 另一種方法: 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每行多數據可參考雙數據方法。也可以參考json方式存儲: 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、寫入文件: 覆蓋寫入: def write = new File(file_path, file_name).newPrintWriter(); write.write(write_text); write.flush(); write.close() 追加寫入: def write = new File(file_path, file_name).newPrintWriter(); write.append(write_text); write.flush(); write.close() 6、json文件的數據處理(import org.ngrinder.recorder.RecorderUtils) json文件讀取: String json_str = new File(file_path).getText("UTF-8") def json_object = RecorderUtils.parseRequestToJson(json_str) 長度:json_object.length() 關鍵字:json_object.keys() 添加元素:json_object.put(name, value) 修改元素:json_object.put(name, value) 刪除元素:json_object.remove(name, value) 獲取對應value:json_object.getString(name) 7、字符串的處理 字符串截取:String new_str = old_str[0..3] 字符串替換:String string = str.replace("old","new") 字符串統計:int count = string.count("char") 字符串轉化:int int_num = Integer.parseInt(string) 1、設置多個請求事務(即多個test方法) 1)設置多個靜態Gtest對象: public static GTest test1 public static GTest test2 2)實例化多個Gtest對象: test1 = new GTest(1, "test1"); test2 = new GTest(2, "test2"); 3)監聽多個test請求: test1.record(this, "test1") test2.record(this, "test2") 4)定義多個test方法: public void test1(){ grinder.logger.info("---ones: {}---", grinder.threadNumber+1) } public void test2(){ grinder.logger.info("---twos: {}---", grinder.threadNumber+1) } 2、Ngrinder定義請求參數集: 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")]; 3、Ngrinder處理日志: 日志級別(三種常見): grinder.logger.info("----before process.----"); grinder.logger.warn("----before process.----"); grinder.logger.error("----before process.----"); 日志限定(僅打印error級別) : 1)導入依賴包 import ch.qos.logback.classic.Level; import org.slf4j.LoggerFactory; 2)設定級別 @BeforeThread LoggerFactory.getLogger("worker").setLevel(Level.ERROR); 3)設置打印語句 @test grinder.logger.error("----error.----"); 日志輸出(輸出所有進程日志):將每個agent的.ngrinder_agent/agent.conf中一項修改為agent.all_logs=true 日志打印:打印變量:grinder.logger.error("{},{}",variable1,variable2); // 換行或縮進可在""中加\n或\t 4、Ngrinder的cookie處理 1) 登錄產生cookie @BeforeThread login_get_cookie(); // 調用登錄方法 cookies = CookieModule.listAllCookies(HTTPPluginControl.getThreadHTTPClientContext()); // 配置cookie管理器 2) 讀取控制器中cookie @Before cookies.each { CookieModule.addCookie(it, HTTPPluginControl.getThreadHTTPClientContext()) } 5、Ngrinder請求方式: 1)通過url加參數直接訪問: 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) 參數是json:設置請求頭參數{"Content-Type": "application/json"} 2)通過參數化所有請求數據為json對象(導入import org.ngrinder.recorder.RecorderUtils) HTTPResponse result = RecorderUtils.sendBy(request, req_data_json) HTTPResponse result = RecorderUtils.sendBy(request, req_data_json) 6、Ngringer的test運行次數設定(將總運行測試次數按百分比例分配到相應test): 1)引用依賴包: import net.grinder.scriptengine.groovy.junit.annotation.RunRate 2)設置運行次數百分比(所有test設定的比例值不夠100,那不滿的部分不運行,比如設定總比80,只運行這80部分): @RunRate(50) // 數字代表百分比 @Test public void test1(){} @RunRate(50) // 數字代表百分比 @Test public void test2(){} 7、Ngringer獲取設置的加壓機總數、進程總數、線程總數等信息: int tota_agents = Integer.parseInt(grinder.getProperties().get("grinder.agents").toString()) // 設置的總加壓機數 int total_processes = Integer.parseInt(grinder.properties().get("grinder.processes").toString()) // 設置的總進程數 int total_threads = Integer.parseInt(grinder.properties().get("grinder.threads").toString()) // 設置的總線程數 int total_runs = Integer.parseInt(grinder.properties().get("grinder.runs").toString()) // 設置的總運行次數(若設置的是運行時長,則得到0) 8、Ngringer獲取當前運行的加壓機編號、進程編號、線程編號等信息(都從0遞增): int agent_number = grinder.agentNumber // 當前運行的加壓機編號 int process_number = grinder.processNumber // 當前運行的進程編號 int thread_number = grinder.threadNumber // 當前運行的線程編號 int run_number = grinder.runNumber // 當前運行的運行次數編號 9、Ngringer獲取唯一遞增值方法(從1遞增,不重復): // 傳遞接口參數runNumber(即def runNumber = grinder.runNumber) private int getIncrementId(int runNumber){ // 獲取壓力機總數、進程總數、線程總數 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()) // 獲取當前壓力機數、進程數、線程數 int agentNum = grinder.agentNumber int processNum = grinder.processNumber int threadNum = grinder.threadNumber // 獲取唯一遞增數id int incrementId = agentNum * totalProcess * totalThreads + processNum * totalThreads + threadNum + totalAgents * totalProcess * totalThreads * runNumber return incrementId } 10、Ngringer根據唯一遞增值獲取參數化文件中的唯一行號: 1)需要設置靜態變量:private enum WhenOutOfValues { AbortVuser, ContinueInCycleManner, ContinueWithLastValue } 2)傳遞接口參數fileDataList(即def fileDataList = new File(dataFilePath).readLines()) private int getLineNum(def fileDataList) { // 獲取當前運行數、數據讀取行數、數據最大行數 int counter = getIncrementId(grinder.runNumber) int lineNum = counter + 1 int maxLineNum = fileDataList.size() - 1 // 讀取最大值的判斷處理 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 } 11、Ngrinder日志輸出配置的測試信息:(import java.text.SimpleDateFormat) public static String getTestInfo(){ String time_string = "" // 獲取壓測時設置的進程總數、線程總數、運行次數並在log中打印 int all_process = grinder.getProperties().getInt("grinder.processes", 1) // 設置的總進程數 int all_threads = grinder.getProperties().getInt("grinder.threads", 1) // 設置的總線程數 int all_runs = grinder.getProperties().getInt("grinder.runs", 1) // 設置的總運行次數(若設置的是運行時長,則得到0) int all_duration = grinder.getProperties().getLong("grinder.duration", 1) // 設置的總運行時長(若設置的是運行次數,則得到0) // 格式化時間毫秒輸出(輸出格式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 } 12、Ngrinder打印所有的配置信息 String property = grinder.getProperties(); grinder.logger.info("------- {}", property) ; 13、Ngrinder獲取請求返回值: 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 返回的狀態碼:grinder.logger.info("----{}----", result.getStatusCode()) // 或者result.statusCode 返回的url:grinder.logger.info("----{}----", result.getEffectiveURI()) 返回的請求頭所有參數:grinder.logger.info("---\n{}---", result) 返回的請求頭某參數:grinder.logger.info("----{}---- ", result.getHeader("Content-type")) 14、Ngrinder返回值的匹配: 匹配狀態碼:assertThat(result.getStatusCode(), is(200)) 匹配包含文本:assertThat(result.getText(), containsString("success")) 15、Ngrinder獲取所有虛擬用戶數: 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; } 16、Ngrinder的斷言和error日志輸出 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)) }
