java - 与 TestNG 并行的参数化 Selenium 测试

Question

首先，对不起我的英语，它不是那么完美:)

所以我面临以下问题:我正在尝试使用 Selenium Grid 和 TestNg 在不同的浏览器中运行并行测试，并在 @BeforeTest 方法中传递参数。我的问题是，当每个测试都被初始化时，它们似乎会使用最后一个测试的参数。所以在这个例子中，当我运行测试时，它会打开两个 Chrome，而不是一个 Firefox 和一个 Chrome。(browser.getDriver() 方法返回一个 RemoteWebDriver)

TestNG.xml:

<suite thread-count="2" verbose="10" name="testSuite" parallel="tests">
  <test name="nameOfTheTestFirefox">
    <parameter name="platform" value="windows"/>
    <parameter name="browserVersion" value="32"/>
    <parameter name="browserName" value="firefox"/>
    <classes>
      <class name="example.test.login.LoginOverlayTest"/>
    </classes>
  </test> <!-- nameOfTheTestFirefox -->
  <test name="nameOfTheTestChrome">
    <parameter name="platform" value="windows"/>
    <parameter name="browserVersion" value="38"/>
    <parameter name="browserName" value="chrome"/>
    <classes>
      <class name="example.test.login.LoginOverlayTest"/>
    </classes>
  </test> <!-- nameOfTheTestChrome -->
</suite> <!-- testSuite -->

AbstractTest 类:

public class SeleniumTest {

    private static List<WebDriver> webDriverPool = Collections.synchronizedList(new ArrayList<WebDriver>());
    private static ThreadLocal<WebDriver> driverThread;
    public static BrowserSetup browser;

    @Parameters({ "browserName", "browserVersion", "platform"})
    @BeforeTest()
    public static void beforeTest(String browserName, @Optional("none") String browserVersion, String platform) throws WrongBrowserException, WrongPlatformException {

        final BrowserSetup browser = new BrowserSetup(browserName, browserVersion, platform);

        driverThread = new ThreadLocal<WebDriver>() {

            @Override
            protected WebDriver initialValue() {
                final WebDriver webDriver = browser.getDriver();
                webDriverPool.add(webDriver);
                return webDriver;
            }

        };

    }

    public static WebDriver getDriver() {
        return driverThread.get();
    }

    @AfterTest
    public static void afterTest() {
        for (WebDriver driver : webDriverPool) {
            driver.quit();
        }
    }

}

还有我的例子@Tests:

@Test
public void test1() throws InterruptedException {
    WebDriver driver = getDriver();
    System.out.println("START: test1");
    driver.get("http://google.com");
    Thread.sleep(5000);
    System.out.println("END:  test1, title: " + driver.getTitle());
}

@Test
public void test2() throws InterruptedException {
    WebDriver driver = getDriver();
    System.out.println("START: test2");
    driver.get("http://amazon.com");
    Thread.sleep(5000);
    System.out.println("END:  test2, title: " + driver.getTitle());
}

@Test
public void test3() throws InterruptedException {
    WebDriver driver = getDriver();
    System.out.println("START: test3");
    driver.get("http://stackoverflow.com");
    Thread.sleep(5000);
    System.out.println("END:  test3, title: " + driver.getTitle());
}

所以我的问题是如何在单独的线程中使用给定参数并行运行测试？

提前致谢!

不要将字段设为静态。

private static List<WebDriver> webDriverPool = Collections.synchronizedList(new ArrayList<WebDriver>());
private static ThreadLocal<WebDriver> driverThread;
public static BrowserSetup browser;
