黄瓜并行 AbstractTestNGCucumberTests 上的 ElementClickInterceptedException

Question

我在 cucumber 6.9.1 中使用 AbstractTestNGCucumberTests 进行并行测试设置，然后使用 RemoteWebDriver 将测试定向到网格

 @Override
  @DataProvider(parallel = true)
  public Object[][] scenarios() {
    return super.scenarios();
  }
}

并像下面这样创建 RemoteWebDriver

 String hubURL = "http://192.168.1.7:65299/wd/hub";
                  System.setProperty("webdriver.gecko.driver", "/Users/../../geckodriver");
                 
                    FirefoxProfile profile = new FirefoxProfile();                   
                    DesiredCapabilities capabilities = DesiredCapabilities.firefox();
                    capabilities.setCapability(FirefoxDriver.PROFILE, profile);
                    capabilities.setPlatform(Platform.ANY);              
                    FirefoxOptions options = new FirefoxOptions();
                    options.merge(capabilities);
                    return driver = new RemoteWebDriver(new URL(hubURL),options);

它打开了两个 firefox 实例，它们相互重叠，我不断得到

org.openqa.selenium.ElementClickInterceptedException: Element <button class="btn btn-link pull-right" 在一个或另一个 firefox 实例上。

我尝试了许多问题中提到的几种解决方案，但它们似乎都对我的方案没有帮助

我尝试了以下解决方案

1. global.wait.until(ExpectedConditions.visibilityOf(PageObjects.AddUser));

2. global.jsExecutor.executeScript("arguments[0].click();", PageObjects.AddUser);

3. PageObjects.AddUser.sendKeys(Keys.ENTER);

4.   Actions builder = new Actions(global.driver); 
                       Action clickElement = (Action) builder.click(PageObjects.AddUser);
                       clickElement.perform();
   

5. global.wait.until(ExpectedConditions.invisibilityOfElementLocated((By) PageObjects.allDom));

我正在 FF 77.0 和 Mac OS (catalina) 上运行测试

我该如何解决这个问题？

编辑。包括ThreadLocal更改

public class FirefoxManager extends DriverManager{
    

    private final ThreadLocal<RemoteWebDriver> driver = new ThreadLocal<>();
    
         @Override
         protected RemoteWebDriver createDriver() throws MalformedURLException , IOException {
                                 
                ClassLoader loader = Thread.currentThread().getContextClassLoader();
                            
                  System.out.println("hubport from sys prop var.."+System.getProperty("hub.port"));
                  String hubURL = "http://192.168.1.7:65299/wd/hub";
                  System.setProperty("webdriver.gecko.driver", "/Users/amit/Desktop/amit/projects/misc/geckodriver");
                 
                    FirefoxProfile profile = new FirefoxProfile();
                
                   
                    DesiredCapabilities capabilities = DesiredCapabilities.firefox();
                    capabilities.setCapability(FirefoxDriver.PROFILE, profile);
                    capabilities.setPlatform(Platform.ANY);                  
                    
                    FirefoxOptions options = new FirefoxOptions();
                    options.merge(capabilities);
                 
                   driver.set(new RemoteWebDriver(new URL(hubURL),options));
                   return driver.get();
        }

Answer 1

您将需要使用 ThreadLocal，因为 WebDriver 不是 ThreadSafe。

复制代码，但思路相同

protected ThreadLocal<WebDriver> wbdriver = new ThreadLocal<WebDriver>();
String url = "https://google.com";
wbdriver.set(new ChromeDriver(options));
wbdriver.get().manage().window().maximize(); 
wbdriver.get().get(url);

我使用 courgette-jvm 实现了黄瓜并行性。它开箱即用并在场景级别运行并行测试

只需在黄瓜中包含类似的跑步者类。我的测试进一步使用RemoteWebdriver 在 selenium 网格上打开多个实例。确保网格已启动并正在运行，并且节点已注册到网格。

import courgette.api.CourgetteOptions;
import courgette.api.CourgetteRunLevel;
import courgette.api.CucumberOptions;
import courgette.api.testng.TestNGCourgette;
import io.cucumber.testng.AbstractTestNGCucumberTests;
import org.testng.annotations.DataProvider;
import org.testng.annotations.Test;
@Test
@CourgetteOptions(
        threads = 10,
        runLevel = CourgetteRunLevel.SCENARIO,
        rerunFailedScenarios = true,
        rerunAttempts = 1,
        showTestOutput = true,
        reportTitle = "Courgette-JVM Example",
        reportTargetDir = "build",
        environmentInfo = "browser=chrome; git_branch=master",
        cucumberOptions = @CucumberOptions(
                features = "src/test/resources/com/test/",
                glue = "com.test.stepdefs",                   
                publish = true,
                plugin = {
                        "pretty",
                        "json:target/cucumber-report/cucumber.json",
                        "html:target/cucumber-report/cucumber.html"}
        ))
class AcceptanceIT extends TestNGCourgette {
}

RemoteWebdriver 配置是

protected RemoteWebDriver createDriver() throws MalformedURLException , IOException {
                   
                 Properties properties = new Properties();                
                ClassLoader loader = Thread.currentThread().getContextClassLoader();                
                  String hubURL = "http://192.168.1.7:65299/wd/hub";
                  System.setProperty("webdriver.gecko.driver", "/Users/amit/Desktop/amit/projects/misc/geckodriver");
                 
                    FirefoxProfile profile = new FirefoxProfile();
                    DesiredCapabilities capabilities = DesiredCapabilities.firefox();
                    capabilities.setCapability(FirefoxDriver.PROFILE, profile);
                    capabilities.setPlatform(Platform.ANY);    
                    FirefoxOptions options = new FirefoxOptions();
                    options.merge(capabilities);                 
                   driver.set(new RemoteWebDriver(new URL(hubURL),options));
                   return driver.get();
        }
