在 Apache Jmeter 中执行基于 Java 的 Selenium WebDriver 测试

Question

我想在 Apache Jmeter 中执行（我想稍后扩展）我的第一个基于 Java 的 Selenium 测试，但我在日志部分收到一条错误消息：

这是我的简单代码：

import org.openqa.selenium.WebDriver;
import org.openqa.selenium.firefox.FirefoxDriver;

System.setProperty("webdriver.gecko.driver","c:\\DEVTOOLS\\PERFORMANCE_TEST\\FIREFOX_GECKO_DRIVER\\geckodriver.exe")
WebDriver driver = new FirefoxDriver();

String url="https://www.google.com/")
driver.get(baseUrl);
driver.close();

这是错误：

我不知道为什么会发生，因为每个 jar 都被复制到： Apache Jmeter lib 文件夹和 lib/ext/ 文件夹。

如果可能，我想离开 WDS.Sampler。这就是我开始使用 SR223Sampler 的原因。

更新：

这是我所拥有的最终解决方案。它按我的预期工作。

import org.openqa.selenium.WebDriver;
import org.openqa.selenium.firefox.FirefoxDriver;
import org.openqa.selenium.firefox.FirefoxOptions;

System.setProperty("webdriver.gecko.driver","c:\\DEVTOOLS\\PERFORMANCE_TEST\\FIREFOX_GECKO_DRIVER\\geckodriver.exe");
FirefoxOptions options = new FirefoxOptions().setAcceptInsecureCerts(true);

WebDriver driver = new FirefoxDriver(options);

String expectedTitle = "Google";
String actualTitle = "";
String baseUrl = "https://google.com";

driver.get(baseUrl);

actualTitle = driver.getTitle();

if (actualTitle.contentEquals(expectedTitle)){
    System.out.println("Test Passed!");
    } else {
    System.out.println("Test Failed");
    }

Thread.sleep(5000);
driver.close();

Answer 1

问题是由于 语法 问题导致的 格式错误 url：

String url="https://www.google.com/")

您需要传递正确的 url 并将该行替换为：

String baseUrl = "https://www.google.com/";

然后将url字符串传递给get()方法，如下：

driver.get(baseUrl);  

此外，在windows 系统上，驱动器是C:（大写）而不是c:（小写）。实际上，该行将是：

System.setProperty("webdriver.gecko.driver","C:\\DEVTOOLS\\PERFORMANCE_TEST\\FIREFOX_GECKO_DRIVER\\geckodriver.exe")
