java，selenium web driver

Posted 2021-04-16

这是Login弹出窗口的快照：

我是Selenium webdriver的新手。我编写了这段代码以找出导航命令但是一旦浏览器打开，就会显示一个登录弹出窗口。我尝试使用classname或xpath关闭它，但发生超时异常。

在这种情况下我是否需要使用显式等待？你能帮我弄清问题是什么吗？

public class TestNavigateCommands {
WebDriver driver;
public void invokeBrowser(){
    try {
        System.setProperty("webdriver.chrome.driver", "/Users/himaja/Documents/chromedriver");
        ChromeOptions options=new ChromeOptions();
        options.addArguments("start-fullscreen");
        driver=new ChromeDriver(options);
        driver.manage().deleteAllCookies();
        driver.manage().timeouts().implicitlyWait(30, TimeUnit.SECONDS);
        driver.manage().timeouts().pageLoadTimeout(40, TimeUnit.SECONDS);
        navigateCommands();
    } catch (Exception e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }
}
public void navigateCommands(){
    try {
        driver.navigate().to("https://www.flipkart.com/");
        Thread.sleep(4000);
        driver.findElement(By.className("2AkmmA _29YdH8")).click();
        //driver.findElement(By.xpath("//*[@class='_2AkmmA _29YdH8']")).click();
        driver.findElement(By.xpath("//span[starts-with(text(),'Applicances')]")).click();
        driver.findElement(By.xpath("//span[contains(text(),'Microwave Ovens')]")).click();
        Thread.sleep(2000);
        driver.navigate().back();
        Thread.sleep(2000);
        driver.navigate().forward();
    } catch (InterruptedException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }



}


public static void main(String[] args) {
    TestNavigateCommands test1= new TestNavigateCommands();
    test1.invokeBrowser();

}

}

例外：

[43.366] [严重]：超时从渲染器接收消息：37.150 [43.373] [严重]：超时从渲染器接收消息：-0.007 org.openqa.selenium.TimeoutException：timeout

答案

试试这个代码可能有所帮助：

public class TestNavigateCommands {
     public static void main(String[] args) throws InterruptedException {
            try {                
                  System.setProperty("webdriver.chrome.driver", "/Users/himaja/Documents/chromedriver");
                  WebDriver driver = new ChromeDriver();
                  driver.manage().timeouts().implicitlyWait(10, TimeUnit.SECONDS);
                  WebDriverWait wait=new WebDriverWait(driver,50 );

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

                  driver.navigate().to("https://www.flipkart.com/");          
                  driver.findElement(By.xpath("//button[contains(@class,'YdH8')]")).click();   


                  wait.until(ExpectedConditions.visibilityOf(driver.findElement(By.xpath("//a[@title='Appliances']//span"))));
                  driver.findElement(By.xpath("//a[@title='Appliances']//span")).click();         

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

另一答案

public class TestNavigateCommands {
WebDriver driver;

public void invokeBrowser() {
    try {
        System.setProperty("webdriver.chrome.driver", "/Users/himaja/Documents/chromedriver");
        ChromeOptions options = new ChromeOptions();
        options.addArguments("start-fullscreen");
        driver = new ChromeDriver(options);
        driver.manage().deleteAllCookies();
        driver.manage().timeouts().implicitlyWait(30, TimeUnit.SECONDS);
        driver.manage().timeouts().pageLoadTimeout(60, TimeUnit.SECONDS);
        navigateCommands();
    } catch (Exception e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }
}

public void navigateCommands() {
    try {
        driver.navigate().to("https://www.flipkart.com/");          
        driver.findElement(By.xpath("//div[@class='_3Njdz7']//button[@class='_2AkmmA _29YdH8']")).click();
        WebDriverWait wait = new WebDriverWait(driver, 30);
        wait.until(ExpectedConditions.visibilityOf(driver.findElement(By.xpath("//a[@title='Appliances']//span"))));
        driver.findElement(By.xpath("//a[@title='Appliances']//span")).click();         
        Thread.sleep(2000);
        driver.navigate().back();
        driver.navigate().forward();
    } catch (InterruptedException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }
}
