在詹金斯（Jenkins）建立TestG maven项目时遇到问题

[英]Having issue building TestG maven project in Jenkins

问题描述

我通过Jenkins构建基于TestNG的Maven项目时遇到问题。 问题是，如果我要运行的测试数量较少（最多30个），则一切运行正常，但是一旦我增加测试数量，构建就会始终失败。 我看到的问题是，直到打开所有浏览器实例（例如，浏览器首先打开30个窗口，然后针对30个测试套件开始执行）之后，测试才会开始，并且当测试完成（而不是整个测试套件）时，浏览器窗口不会关闭（即使在添加driver.quit（）方法之后），并且在TestSuite运行完成之前它将保持打开状态。

以下是我的代码段。

Java主要类别： 

public class AccountManagement {
    public WebDriver driver = new FirefoxDriver();
    public WebDriverWait wait = new WebDriverWait(driver, 20);
    public void login(String uid, String pass) throws Throwable {
        driver.manage().window().maximize();
        driver.get(URL);
        driver.findElement(By.id("Email")).sendKeys(uid);
        driver.findElement(By.id("Password")).sendKeys(pass);
        driver.findElement(By.id("btnLogin")).click();

        <!-- REST OF THE CODE-->
    }
}

示例测试类： 

public class TC_AC408 extends AccountManagement {

    @Test(retryAnalyzer=Retry.class)
    public void accountActionLinks() {
        login("auto.admin@test.com", "test@123");
        <!-- REST OF THE CODE-->
    }

    @AfterTest
    public void end() {
        driver.quit();
    }
}

这是我的testng.xml：

您可以随时为测试中的每个类创建驱动程序实例，并且每个测试仅退出一次驱动程序，而不是直接在类中实例化WebDriver，而是在@BeforeTest中进行创建。 这将确保每个测试仅创建一个驱动程序。

升级后，您的班级如下所示。 

public class AccountManagement {
public WebDriver driver;
public WebDriverWait wait;
@BeforeTest
public void beforeTest(){
    driver = new FirefoxDriver();
    wait = new WebDriverWait(driver, 20);
}
public void login(String uid, String pass) throws Throwable {
    driver.manage().window().maximize();
    driver.get(URL);
    driver.findElement(By.id("Email")).sendKeys(uid);
    driver.findElement(By.id("Password")).sendKeys(pass);
    driver.findElement(By.id("btnLogin")).click();

    <!-- REST OF THE CODE-->
 }
}
