java - Webdriver:为什么我仍然得到 'Unexpected Alert Open'？

Question

我创建了以下方法，单击特定按钮将打开警报，下面列出的相同方法将处理警报。

但我似乎得到了奇怪的 Jenkins 构建，它将(间歇性地) 由于意外警报打开(下面列出的异常)而失败，有什么想法吗？

public void clickPaySecurelyNowButton() throws InterruptedException {
        waitAndclickElementUsingJS(button_PaySecurelyNowTop);

        WebDriverWait tempWait = new WebDriverWait(this.driver, 30);
        Alert alert = tempWait.until(ExpectedConditions.alertIsPresent());
        boolean boolAlert = false;
        int attempts = 0;
        while (!boolAlert && attempts < 1000) {
            try {
                driver.switchTo().alert().accept();
                System.out.println("Successfully clicked on the 'Pay Securely Now Button' and 'Closed the popup'");
                boolAlert = true;
            } catch (org.openqa.selenium.UnhandledAlertException e) {
                driver.switchTo().alert().accept();
                boolAlert = true;
                System.out.println("Sucesffuly clicked on the 'Pay Securely Now Button' and 'Closed the popup'");
            } catch (Exception e) {
                System.out.println("Unable to click on the 'Pay Securely Now Button', Exception: " + e.getMessage());
                Assert.fail("Method failed: clickPaySecurelyNowButton");
            }
        } attempts++;
    }

Answer 1

在这一行中，您已经收到警报:Alert alert = tempWait.until(ExpectedConditions.alertIsPresent());

与其编写 driver.switchTo().alert().accept();，不如尝试这样做:alert.accept();

更新:
如果您只想不惜一切代价接受警报，最好将您的 try block 移到点击线之外。我有充分的理由相信点击行会导致您未处理的警报异常，因为我之前遇到过同样的问题。

尝试像这样更新您的代码:

public void clickPaySecurelyNowButton() throws InterruptedException {

    try {
        waitAndclickElementUsingJS(button_PaySecurelyNowTop);

        WebDriverWait tempWait = new WebDriverWait(this.driver, 30);
        tempWait.until(ExpectedConditions.alertIsPresent());
        boolean boolAlert = false;
        int attempts = 0;
        while (!boolAlert && attempts < 1000) {
            attempts++;
            driver.switchTo().alert().accept();
            System.out.println("Successfully clicked on the 'Pay Securely Now Button' and 'Closed the popup'");
            boolAlert = true;
        }
    } catch (org.openqa.selenium.UnhandledAlertException e) {
        driver.switchTo().alert().accept();
        boolAlert = true;
        System.out.println("Sucesffuly clicked on the 'Pay Securely Now Button' and 'Closed the popup'");
    } catch (Exception e) {
        System.out.println("Unable to click on the 'Pay Securely Now Button', Exception: " + e.getMessage());
        Assert.fail("Method failed: clickPaySecurelyNowButton");
    }
}

您可以在驱动程序实例化期间使用 chrome 功能使用全局设置:

DesiredCapabilities capabilities = DesiredCapabilities.chrome();
capabilities.setCapability(CapabilityType.UNEXPECTED_ALERT_BEHAVIOUR, UnexpectedAlertBehaviour.ACCEPT);

WebDriver driver = new ChromeDriver(capabilities);
