JSR223采样器的WDS.sampleResult.sampleStart

编程问答 2022-06-10

问题描述

我正在使用JSR223采样器，我想在URL加载后开始计算时间，因此我的代码如下：

** 

import org.openqa.selenium.WebDriver;
import org.openqa.selenium.firefox.FirefoxDriver;
import org.openqa.selenium.firefox.FirefoxOptions;
import org.openqa.selenium.By;
import org.openqa.selenium.support.ui.ExpectedConditions;
import org.openqa.selenium.support.ui.webdriverwait;
System.setProperty("webdriver.gecko.driver","/Users/geckodriver");
FirefoxOptions options = new FirefoxOptions().setAcceptInsecureCerts(true);
options.addArguments("--headless");
WebDriver driver = new FirefoxDriver(options);
def wait = new webdriverwait(driver,20);
driver.get('https://google.com/');
WDS.sampleResult.sampleStart();
wait.until(ExpectedConditions.visibilityOfElementLocated(By.xpath(".//input[@name='q']")));
WDS.sampleResult.sampleEnd();

**

解决方法

JSR223 Sampler根据脚本内容自动计算持续时间，因此，如果要测量查找输入所需的时间，则必须选择以下选项：

  1. 创建另一个JSR223采样器，它将打开所需的页面并将WebDriver实例存储到JMeterVariables中，例如：

    • 第一个JSR223采样器：

      import org.openqa.selenium.WebDriver;
import org.openqa.selenium.firefox.FirefoxDriver;
import org.openqa.selenium.firefox.FirefoxOptions;
import org.openqa.selenium.support.ui.WebDriverWait;
System.setProperty("webdriver.gecko.driver","/Users/geckodriver");
FirefoxOptions options = new FirefoxOptions().setAcceptInsecureCerts(true);
options.addArguments("--headless");
WebDriver driver = new FirefoxDriver(options);
def wait = new WebDriverWait(driver,20);
driver.get('https://google.com/');

vars.putObject('driver',driver)
vars.putObject('wait',wait)

    • 第二个JSR223采样器：

       import org.openqa.selenium.By;
 import org.openqa.selenium.support.ui.ExpectedConditions;

 def driver = vars.getObject('driver')
 def wait = vars.getObject('wait')
 wait.until(ExpectedConditions.visibilityOfElementLocated(By.xpath(".//input[@name='q']")));

  2. 使用SampleResult.addSubResult()函数创建一个“子”样本结果，该结果将测量定位元素所需的时间：

    import org.openqa.selenium.WebDriver;
import org.openqa.selenium.firefox.FirefoxDriver;
import org.openqa.selenium.firefox.FirefoxOptions;
import org.openqa.selenium.By;
import org.openqa.selenium.support.ui.ExpectedConditions;
import org.openqa.selenium.support.ui.WebDriverWait;
System.setProperty("webdriver.gecko.driver",20);
driver.get('https://google.com/');

def myResult = new org.apache.jmeter.samplers.SampleResult()
myResult.setSampleLabel('Locating element')
myResult.sampleStart()
wait.until(ExpectedConditions.visibilityOfElementLocated(By.xpath(".//input[@name='q']")));
myResult.setResponseCodeOK()
myResult.setSuccessful(true)
myResult.sampleEnd()

SampleResult.addSubResult(myResult,false)

    在这种情况下，您会得到类似的东西：
