java - 如何与实现 ITestListener 的 TestNG 结合使用 Firefox 驱动程序

Question

非常感谢您在这里提供任何建议。我正在尝试使用 TestNG 并实现 ITestListerner 接口(interface)来使用 POM 框架中的驱动程序对象。

这是一个实现 ItestListener 的 TestNG 类

public class TestNGListener implements ITestListener {

@Override
public void onFinish(ITestContext result) {


    WebDriver driver = BrowserFactory.LanuchBrowser("firefox", "http://10.207.182.108:81/opencart/");
    Util.takescreenshot(driver, result.getName());


}

此类用于在从 switch case 启动浏览器之一后返回 WebDriver 对象。我通过在上面的类中实现 IteSTListener 和覆盖 failure public void onFinish(ITestContext result) 来使用与 TestNG 相同的驱动程序，不幸的是，它不会返回 webdriver 对象并拍摄屏幕截图，但是相反，启动一个新的浏览器。

public class BrowserFactory {

static WebDriver driver;

    public  static WebDriver LanuchBrowser(String Brwsr, String URL){

        System.out.println(Brwsr.toLowerCase());
        switch (Brwsr.toLowerCase()){

            case "firefox":
                        driver=new FirefoxDriver();
                        break;
            case "chrome":
                        driver= new ChromeDriver();
                        System.setProperty("WebDriver.chrome.driver", "chromedriver.exe");
                        break;

            case "internet explorer":
                        System.out.println("IE");
                        driver= new InternetExplorerDriver();
                        System.setProperty("WebDriver.IE.driver","IEDriverServer.exe");
                        break;
            default:
                        System.out.println("Please select one of the Browsers listed : Chrome,Firefox or InternetExplorer");
                        break;
        }   


            driver.manage().window().maximize();
            driver.get(URL);                    


        return driver;

    }
}

这是我捕获屏幕截图的方法

public class Util {

final static Logger logger = Logger.getLogger(Util.class);      

public static void validatePgeNavgtn(WebDriver driver, String PgeTitle){
    PropertyConfigurator.configure("log4j.properties");


    String pgtitle=driver.getTitle();

    if (pgtitle.equalsIgnoreCase(PgeTitle)){
    logger.info("title matched");       
    } 
}

public static void takescreenshot(WebDriver driver, String screen){
    TakesScreenshot ts = (TakesScreenshot)driver;
    File src=  ts.getScreenshotAs(OutputType.FILE);
    try {
        FileUtils.copyFile(src, new File("./Screenshot/"+screen+".png"));
    } catch (IOException e) {
        logger.warn(e.getMessage());
    }
}

您能否建议一种方法，以下方法不应启动新的浏览器 session ，但焦点应保留在第一个浏览器实例上并捕获屏幕截图

您需要将 BrowserFactory 类创建为单例，它将始终创建 BrowserFactory 的单个实例，如下所示:-

public class BrowserFactory {

    private WebDriver driver;
    private static BrowserFactory browserFactoryInstance = null;

    private BrowserFactory(String Brwsr, String URL) {

        System.out.println(Brwsr.toLowerCase());
        switch (Brwsr.toLowerCase()) {

        case "firefox":
            this.driver = new FirefoxDriver();
            break;
        case "chrome":
            System.setProperty("WebDriver.chrome.driver", "chromedriver.exe");
            this.driver = new ChromeDriver();
            break;

        case "internet explorer":
            System.out.println("IE");
            System.setProperty("WebDriver.IE.driver", "IEDriverServer.exe");
            this.driver = new InternetExplorerDriver();
            break;
        default:
            System.out
                    .println("Please select one of the Browsers listed : Chrome,Firefox or InternetExplorer");
            break;
        }

        this.driver.manage().window().maximize();
        this.driver.get(URL);

    }

    public static BrowserFactory getInstance(String Brwsr, String URL) {
        if(browserFactoryInstance == null) {
            browserFactoryInstance = new BrowserFactory(Brwsr, URL);
        }
        return browserFactoryInstance;
    }

    public WebDriver getDriver() {
        return this.driver;
    }
}

现在您可以获得 WebDriver 实例，如下所示:-

//It will return always single instance per test run
WebDriver driver = BrowserFactory.getInstance("firefox", "http://10.207.182.108:81/opencart/").getDriver();
Util.takescreenshot(driver, result.getName());
