使用单个驱动程序实例的TestNG并行执行

标签: java selenium testng

在我的测试套件中,我有一个基类,在该基类中声明一个静态WebDriver,然后以打开基URL的方法将其生成为ChromeDriver,FirefoxDriver等。在我的所有测试用例中,此方法都用在我的BeforeMethod中,因此,在每次测试执行中,以及在测试用例中使用的一系列可重用方法(例如,登录方法)中,都使用单个静态驱动程序实例。 / p>

现在,我试图引入并行执行,这似乎是一个问题,因为对于我想同时运行的任何脚本,我都需要单独的驱动程序实例,以避免线程干扰。有什么方法可以使我的脚本并行运行而无需重新构建整个套件,从而使每个脚本完全独立地编写?

我尝试声明一个WebDrivers数组,然后根据从启动套件XML发送的参数选择一个特定的索引,但这没有帮助。第二个浏览器打开,但是里面什么也没有。

这是我的基础课:

public class Base {


public static WebDriver driver = null;

//Input client under test
public static final String Client = "Client1";

//Input default environment under test
public static final String DefaultEnvironment = "Chrome_Hub";


//CALL WEB BROWSER AND OPEN WEBSITE
public static void openURL(String environment) throws InterruptedException, IOException {

    try{

        if(environment.equals("Chrome_Hub")) {
            System.setProperty("webdriver.chrome.driver", "/Users/rossdonohoe/Desktop/SeleniumJava/Drivers/chromedriver");
            driver = new ChromeDriver();
        }
        if(environment.equals("Firefox_Hub")) {
            System.setProperty("webdriver.gecko.driver", "/Users/rossdonohoe/Desktop/SeleniumJava/Drivers/geckodriver");
            driver = new FirefoxDriver();
        }

        driver.get(DataFinder.ReadData("front end url"));


    }
    catch(Exception E) {
        E.printStackTrace();
    }
}
}

这是一个示例脚本:

public class LoginLogoutScript extends Base {


  @Test (priority = 2)
  public void login() throws InterruptedException, IOException {
        LoginLogout.loginFrontEnd();
        Assert.assertTrue(driver.getPageSource().contains("My Account") || driver.getPageSource().contains("My Dashboard"));
  }

  @Parameters({ "Environment" })
  @BeforeClass
  public void setUp(@Optional(DefaultEnvironment) String Environment) throws InterruptedException, IOException {
      Base.openURL(Environment);
  }

  @AfterClass public void tearDown() { 
      Base.driver.quit(); 
  }

}

这是该脚本中调用的方法:

public class LoginLogout extends Base {

    public static void loginFrontEnd () throws InterruptedException, IOException {
        Thread.sleep(5000);
        WebDriverWait wait = new WebDriverWait(driver, 10);
        WebElement login2 = wait.until(ExpectedConditions.elementToBeClickable(By.linkText(DataFinder.ReadData("sign in link"))));
        ((JavascriptExecutor)driver).executeScript("arguments[0].click();", login2);
        WebDriverWait wait = new WebDriverWait(driver, 15);
        wait.until(ExpectedConditions.visibilityOfElementLocated(By.id("email")));
        driver.findElement(By.id("email")).sendKeys(DataFinder.ReadData("username entry"));
        driver.findElement(By.id("pass")).sendKeys("I$$\"Cnewton1");
        Thread.sleep(5000);
        driver.findElement(By.id("send2")).click();
    }
}

这是另一个脚本:

@Listeners(CustomListener.class)
public class CreateDeleteCustomerAccountScript extends Base {

  @Test (priority = 1)
  public void createAccount() throws InterruptedException, IOException {

        WebDriverWait wait = new WebDriverWait(driver, 15);
        wait.until(ExpectedConditions.visibilityOfElementLocated(By.partialLinkText(DataFinder.ReadData("navigate to register account 1"))));
        driver.findElement(By.partialLinkText(DataFinder.ReadData("navigate to register account 1"))).click();

        driver.findElement(By.cssSelector(DataFinder.ReadData("navigate to register account 2"))).click();

        driver.findElement(By.name("firstname")).sendKeys("Testy");
        driver.findElement(By.name("lastname")).sendKeys("McTester");
        driver.findElement(By.cssSelector("#email_address")).sendKeys(Misc.generateRandomString() + "@thepixel.com");
        driver.findElement(By.name("password")).sendKeys("I$$\"Cnewton1");
        driver.findElement(By.name(DataFinder.ReadData("password confirmation"))).sendKeys("I$$\"Cnewton1");

            //verify account created
        Thread.sleep(5000);
        Assert.assertTrue(driver.findElement(By.tagName("body")).getText().contains(DataFinder.ReadData("account created message")));
  }

  @Parameters({ "Environment" })
  @BeforeClass
  public void setUp(@Optional(DefaultEnvironment) String Environment) throws InterruptedException, IOException {
      Base.openURL(Environment, "front end");
  }

  @AfterClass public void tearDown() { 
      Base.driver.quit(); 
  }
}

这是我的XML文件:

<?xml version="1.0" encoding="UTF-8"?>

<suite name="FullRegressionSuite" parallel="tests" thread-count="2">
<listeners>

</listeners>

  <test name="Test1">
   <parameter name ="DriverNo" value="1"/>
    <classes>
      <class name="userManagement.LoginLogoutScript"/>
    </classes>
  </test>
  <test name="Test2">
    <parameter name ="DriverNo" value="2"/>
    <classes>
      <class name="userManagement.CreateDeleteCustomerAccountScript"/>"/>
    </classes>
  </test>

       <!-- Test -->
</suite> <!-- Suite -->

如果您通过Maven执行测试,则可以重新考虑Fork Options,以便每个TestNG线程将在单独的JVM实例中执行

<forkCount>2</forkCount> <!- amend this to be equal to the number of TestNG threads -->
<reuseForks>false</reuseForks>

无论如何,它只能掩盖问题,更大的限制是您正在使用static modifier for WebDriver instance,它肯定违反了Parallel Testing Best Practices

您可以使用如下所示的threadlocal webdriver。

public class Base {


public static ThreadLocal<WebDriver> driver = new ThreadLocal<>();

//Input client under test
public static final String Client = "Client1";

//Input default environment under test
public static final String DefaultEnvironment = "Chrome_Hub";


//CALL WEB BROWSER AND OPEN WEBSITE
public static void openURL(String environment) throws InterruptedException, IOException {

    try{

        if(environment.equals("Chrome_Hub")) {
            System.setProperty("webdriver.chrome.driver", "/Users/rossdonohoe/Desktop/SeleniumJava/Drivers/chromedriver");
            driver.set(new ChromeDriver());
        }
        if(environment.equals("Firefox_Hub")) {
            System.setProperty("webdriver.gecko.driver", "/Users/rossdonohoe/Desktop/SeleniumJava/Drivers/geckodriver");
            driver.set(new FirefoxDriver());
        }

        driver.get(DataFinder.ReadData("front end url"));


    }
    catch(Exception E) {
        E.printStackTrace();
    }
}
}

您可以使用driver.get()方法获取它的实例。

public class LoginLogoutScript extends Base {


  @Test (priority = 2)
  public void login() throws InterruptedException, IOException {
        LoginLogout.loginFrontEnd();
        Assert.assertTrue(driver.getPageSource().contains("My Account") || driver.get().getPageSource().contains("My Dashboard"));
  }

  @Parameters({ "Environment" })
  @BeforeClass
  public void setUp(@Optional(DefaultEnvironment) String Environment) throws InterruptedException, IOException {
      Base.openURL(Environment);
  }

  @AfterClass public void tearDown() { 
      Base.driver.get().quit(); 
  }

}
