用TestNG和Java并行测试(Selenium)

Question

我想实现并行测试，但似乎有些东西没有正常工作。当我为浏览器执行测试用例浏览器时，测试用例将通过100%.但是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Eclipse上执行我的测试用例，它们运行在带有Selenium网格的Docker上。

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;
  }

}

这个类名为setup.java，这个类调用我在xml上安装的浏览器。

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解答。

1. 如何改进我的代码以并行运行我的测试用例(我指的是火狐和Chrome同时运行同一个测试用例)
2. 当一个测试用例在执行失败时，另一个测试用例被跳过。

我已经将您的setup.java类合并到BrowserFactory类中，以临时编写您的代码。在这里，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);

}
}

更新您的xml accordingly.hope，这对您有帮助。
