使用TestNG和Java（Selenium）进行并行测试

Question

我想实现并行测试，但似乎有些东西不能正常工作。当我为浏览器执行测试用例浏览器时，测试用例100%通过。。。但当我实现并行测试时，它们很少通过，但通常是失败的

我正在EclipseIDE上执行测试用例，它们在Docker上运行，并带有Selenium网格

这是我的浏览器并行测试类：

    public class BrowserFactory {

  private static final String FIREFOX = "firefox";
  private static final String CHROME = "chrome";
  private static final String SAFARI = "safari";
  private static final String IE = "internet explorer";

  private static String seleniumGridHub = UtlManageConfig.gethubURL();
  private static String weburl = UtlManageConfig.getWEBURL();

  public static DesiredCapabilities capabilities = null;
  public static MutableCapabilities options = null;


  public static WebDriver createInstance(String multiBrowser) throws MalformedURLException {
    WebDriver driver = null;
    try {

      switch(multiBrowser){

        case FIREFOX:
          FirefoxProfile profile = new FirefoxProfile();
          profile.setPreference("dom.disable_beforeunload", true);
          profile.setPreference("browser.helperApps.neverAsk.saveToDisk", "text/csv");             
          options = new FirefoxOptions();
          options.setCapability(FirefoxDriver.PROFILE, profile);
          options.setCapability("moz:webdriverClick", false);
          options.setCapability(CapabilityType.BROWSER_NAME, FIREFOX);

          URL server = new URL(seleniumGridHub);
          driver = new RemoteWebDriver(server, options);




          break;

        case CHROME:
          ChromeOptions chromeOptions = new ChromeOptions();
          chromeOptions.addArguments("--disable-popup-blocking");
          chromeOptions.setCapability(CapabilityType.BROWSER_NAME, CHROME);
          URL server2 = new URL(seleniumGridHub);
          driver = new RemoteWebDriver(server2, chromeOptions);


          break;

        case SAFARI:

          SafariOptions safariOptions = new SafariOptions();
          safariOptions.setUseTechnologyPreview(true);

          driver = new SafariDriver(safariOptions);
          break;

        default:
          InternetExplorerOptions ieOptions = new InternetExplorerOptions();
          driver = new InternetExplorerDriver(ieOptions);
          break;

      }

    }catch (Exception e) {
      e.getStackTrace();

      return driver;
    }

    return driver;
  }

}

这个类被称为setup.java，这个类调用我放在xml上的浏览器

public WebDriver driver = null;
driver = BrowserFactory.createInstance(browser);
DriverFactory.getInstance().setDriver(driver);
      driver = DriverFactory.getInstance().getDriver();
      driver.get(weburl);

      driver.manage().window().maximize();
      driver.manage().timeouts().implicitlyWait(5, TimeUnit.SECONDS);

这是我的XML：

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE suite SYSTEM "http://testng.org/testng-1.0.dtd">
<suite name="books Test" parallel= "tests">
    <test name="Firefox Test">
        <parameter name="browser" value="firefox" />
        <groups>
            <run>
                <include name="books" />
                <include name="bookssell" />
            </run>
        </groups>
        <classes>
            <class
                name="books" />
        </classes>
    </test>
    <test name="Chrome Test">
        <parameter name="browser" value="chrome" />
        <groups>
            <run>
                <include name="books" />
                <include name="bookssell" />
            </run>
        </groups>
        <classes>
            <class
                name="books" />
        </classes>
    </test>
</suite>

我有两个问题，我很想在这篇文章中得到回答

1. 如何改进代码以并行运行测试用例（我指的是Firefox和Chrome同时使用相同的测试用例）

2. 当一个测试用例执行失败时，将跳过其他测试用例

Answer 1

我已经合并了你的设置。BrowserFactory类中的java类来临时编写代码。 以下是您的更新代码：

public class BrowserFactory {

  private static final String FIREFOX = "firefox";
  private static final String CHROME = "chrome";
  private static final String SAFARI = "safari";
  private static final String IE = "internet explorer";

  private static String seleniumGridHub = UtlManageConfig.gethubURL();
  private static String weburl = UtlManageConfig.getWEBURL();

  public static DesiredCapabilities capabilities = null;
  public static MutableCapabilities options = null;
  Public WebDriver driver;


  public static createInstance(String multiBrowser) throws MalformedURLException {

    try {

      switch(multiBrowser){

        case FIREFOX:
          FirefoxProfile profile = new FirefoxProfile();
          profile.setPreference("dom.disable_beforeunload", true);
          profile.setPreference("browser.helperApps.neverAsk.saveToDisk", "text/csv");             
          options = new FirefoxOptions();
          options.setCapability(FirefoxDriver.PROFILE, profile);
          options.setCapability("moz:webdriverClick", false);
          options.setCapability(CapabilityType.BROWSER_NAME, FIREFOX);

          URL server = new URL(seleniumGridHub);
          driver = new RemoteWebDriver(server, options);




          break;

        case CHROME:
          ChromeOptions chromeOptions = new ChromeOptions();
          chromeOptions.addArguments(" disable-popup-blocking");
          chromeOptions.setCapability(CapabilityType.BROWSER_NAME, CHROME);
          URL server2 = new URL(seleniumGridHub);
          driver = new RemoteWebDriver(server2, chromeOptions);


          break;

        case SAFARI:

          SafariOptions safariOptions = new SafariOptions();
          safariOptions.setUseTechnologyPreview(true);

          driver = new SafariDriver(safariOptions);
          break;

        default:
          InternetExplorerOptions ieOptions = new InternetExplorerOptions();
          driver = new InternetExplorerDriver(ieOptions);
          break;

      }

    }catch (Exception e) {
      e.getStackTrace();


    }


  }

  public static Browserlogin(String multiBrowser){
driver = BrowserFactory.createInstance(browser);
DriverFactory.getInstance().setDriver(driver);
      driver = DriverFactory.getInstance().getDriver();
      driver.get(weburl);

      driver.manage().window().maximize();
      driver.manage().timeouts().implicitlyWait(5, TimeUnit.SECONDS);

}
}

相应地更新xml。希望这对你有帮助

  private static final String FIREFOX = "firefox";
  private static final String CHROME = "chrome";
  private static final String SAFARI = "safari";
  private static final String IE = "internet explorer";

  private static String weburl = UtlManageConfig.getWEBURL();

 @BeforeMethod 
 @Parameters(value={"multiBrowser"})

          URL server = new URL(seleniumGridHub);

          break;

    }


  }
  public WebDriver getDriver() {

        return driver;
    }
      @AfterMethod
    public void tearDown() {
        getDriver().quit();
    }

}

@Test
Class setup extends BrowserFactory{


       getDriver().get(weburl);

      getDriver().manage().window().maximize();
      getDriver().manage().timeouts().implicitlyWait(5, TimeUnit.SECONDS);
