如何 运行 我的 selenium 测试方法并行使用 testng

how to run my selenium test methods in parallel using testng

我正在尝试 运行 我的自动化测试(Selenium webdriver)使用 testng 并行。这是我所在的节点 运行ning:

java -Dwebdriver.gecko.driver=chromedriver.exe -jar selenium-server-standalone-3.4.0.jar -role node -hub http://localhost:4444/grid/register -browser browserName=chrome,maxInstances=2 -maxSession 2

这是我的测试class:

public class TestParallel {

Login login;

//@BeforeMethod(alwaysRun = true)
public SeleniumDriverCore testSetup() throws FileNotFoundException, IOException{
    SeleniumDriverCore driver = new SeleniumDriverCore("config/chromeDriverConfig");
    Properties config = new Properties();
    config.load(new FileInputStream("config/testConfig"));
    this.login = new Login(driver);
    driver.browser.open("https://test.test.xyz");

    driver.browser.maximize();
    driver.waits.waitForPageToLoad();
    return driver;
}

@Test(groups={"parallel"})
public void test_one() throws FileNotFoundException, IOException{
    SeleniumDriverCore driver=testSetup();
    login.navigateToPage(Pages.LOGIN);
    login.assertion.verifyLoginPopupAndTitleDisplayed();
    testCleanup(driver);
}

@Test(groups={"parallel"})
public void test_two() throws FileNotFoundException, IOException{
    SeleniumDriverCore driver=testSetup();
    login.navigateToPage(Pages.LOGIN);
    login.assertion.verifyLoginPopupAndTitleDisplayed();
    testCleanup(driver);
}

@Test(groups={"parallel"})
public void test_three() throws FileNotFoundException, IOException{
    SeleniumDriverCore driver=testSetup();
    login.navigateToPage(Pages.LOGIN);
    login.assertion.verifyLoginPopupAndTitleDisplayed();
    testCleanup(driver);
}

@Test(groups={"parallel"})
public void test_four() throws FileNotFoundException, IOException{
    SeleniumDriverCore driver=testSetup();
    login.navigateToPage(Pages.LOGIN);
    login.assertion.verifyLoginPopupAndTitleDisplayed();
    testCleanup(driver);
}


public void testCleanup(SeleniumDriverCore driver){
    driver.close();
    driver.quit();
}

}

这是我的 xml:

<suite name="Ontega - All Tests Mobile" parallel="methods" thread-count="2">
    <test name="Ontega - All Tests Mobile">
        <groups>
            <run>
                <include name="parallel"/>
                <exclude name="open-defects"/>
            </run>
        </groups>
        <packages>
            <package name="tests.*"/>
        </packages>
    </test>
</suite>

当我 运行 XML 时,我希望我的测试 运行 同时在两个浏览器上以两个线程进行测试,但是当我 运行 XML 我第一次得到两个浏览器实例 运行ning 然后它们递增并且 50% 的测试失败了,正如你所看到的我试图在每个实例中实例化驱动程序我的方法,虽然这不是我的框架的工作方式,但我正在努力解决这个问题的瓶颈。 任何帮助将不胜感激 提前致谢

您似乎为每个测试创建了多个驱动程序。我猜你需要在 testSetup() 方法之外保留一些代码

SeleniumDriverCore driver = new SeleniumDriverCore("config/chromeDriverConfig");
Properties config = new Properties();
config.load(new FileInputStream("config/testConfig"))

我正在分享我用于并行测试的部分代码,这可能对您的情况有所帮助

我的xml

这里有一些在 TestNG 中执行此操作的方法。您基本上通过 @BeforeMethod@AfterMethod 配置方法管理您的 webdriver 实例化和清理。因此,您需要决定如何与 @Test 方法共享创建的 webdriver 实例。为此,您有三个选择:

  1. 您使用了 ThreadLocal 变体,因为 TestNG 向您保证它将在同一个线程中执行 @BeforeMethod@Test@AfterMethod

这是一个向您展示实际操作的示例

import org.openqa.selenium.chrome.ChromeDriver;
import org.openqa.selenium.remote.RemoteWebDriver;
import org.testng.ITestResult;
import org.testng.Reporter;
import org.testng.annotations.AfterMethod;
import org.testng.annotations.BeforeMethod;
import org.testng.annotations.DataProvider;
import org.testng.annotations.Test;

public class TestClassSampleUsingThreadLocal {
    private static final ThreadLocal<RemoteWebDriver> drivers = new ThreadLocal<>();

    @BeforeMethod
    public void instantiateBrowser(ITestResult testResult) {
        RemoteWebDriver driver = new ChromeDriver();
        drivers.set(driver);
    }

    @Test(dataProvider = "dp")
    public void testMethod(String url) {
        Reporter.log("Launching the URL [" + url + "] on Thread [" + Thread.currentThread().getId() + "]", true);
        driver().get(url);
        Reporter.log("Page Title :" + driver().getTitle(), true);
    }

    @DataProvider(name = "dp", parallel = true)
    public Object[][] getData() {
        return new Object[][]{
                {"http://www.google.com"}, {"http://www.whosebug.com"}, {"http://facebook.com"}
        };
    }

    @AfterMethod
    public void cleanupBrowser() {
        RemoteWebDriver driver = driver();
        driver.quit();
    }

    private RemoteWebDriver driver() {
        RemoteWebDriver driver = drivers.get();
        if (driver == null) {
            throw new IllegalStateException("Driver should have not been null.");
        }
        return driver;
    }

}
  1. 您可以通过 ITestResult 对象共享 webdriver 实例。这是一个示例,显示了实际情况。
import org.openqa.selenium.chrome.ChromeDriver;
import org.openqa.selenium.remote.RemoteWebDriver;
import org.testng.ITestResult;
import org.testng.Reporter;
import org.testng.annotations.AfterMethod;
import org.testng.annotations.BeforeMethod;
import org.testng.annotations.DataProvider;
import org.testng.annotations.Test;

public class TestClassSample {
    private static final String WEBDRIVER = "driver";

    @BeforeMethod
    public void instantiateBrowser(ITestResult testResult) {
        RemoteWebDriver driver = new ChromeDriver();
        testResult.setAttribute(WEBDRIVER, driver);
    }

    @Test(dataProvider = "dp")
    public void testMethod(String url) {
        Reporter.log("Launching the URL [" + url + "] on Thread [" + Thread.currentThread().getId() + "]", true);
        driver().get(url);
        Reporter.log("Page Title :" + driver().getTitle(), true);
    }

    @DataProvider(name = "dp", parallel = true)
    public Object[][] getData() {
        return new Object[][]{
                {"http://www.google.com"},
                {"http://www.whosebug.com"},
                {"http://facebook.com"}
        };
    }

    @AfterMethod
    public void cleanupBrowser(ITestResult testResult) {
        RemoteWebDriver driver = driver(testResult);
        driver.quit();
    }

    private RemoteWebDriver driver() {
        return driver(Reporter.getCurrentTestResult());
    }

    private RemoteWebDriver driver(ITestResult testResult) {
        if (testResult == null) {
            throw new IllegalStateException("testResult should have not been null.");
        }
        Object driverObject = testResult.getAttribute(WEBDRIVER);
        if (driverObject == null) {
            throw new IllegalStateException("Driver should have not been null.");
        }
        if (!(driverObject instanceof RemoteWebDriver)) {
            throw new IllegalStateException("Driver is not a valid webdriver object");
        }
        return (RemoteWebDriver) driverObject;
    }
}
  1. 您将 webdriver 实例化和清理提取到 TestNG 侦听器(实现 org.testng.IInvokedMethodListener 的侦听器,它将创建的 webdriver 设置为 ITestResult(如选项 2 所示)或 ThreadLocal(如选项 1 所示)。您可以在我的 blog post.
  2. 中找到有关此选项的更多详细信息以及代码片段
