Question

任何人都可以帮我解决以下我希望在if / else条件下使用的场景。我正在使用带有Testng Eclipse的java。

1）如果登录成功并导航到主页，请避免尝试/捕获 2）如果登录失败，请转到尝试阻止。

        driver.findElement(By.name("username")).sendKeys(username);
        driver.findElement(By.name("password")).sendKeys(password);
        driver.findElement(By.name("login")).submit();

      try{

        Assert.assertFalse(driver.findElement(By.xpath("//div[@class='errorMsg']")).getText().matches("Username or password incorrect. Try again."));
        }
        catch(Throwable t){
            Assert.fail("Username Or Password is Incorrect.");
        }
        Assert.assertEquals(actualTitle, title,"Home is not accessible!");

这就像用try-catch替换if一样简单，但如果没有找到任何元素，findBy会抛出异常，那么至少有以下两种方法< / p>

1）创建一个可重用的findElementIfPresent方法，如果没有找到任何元素，则返回null：

    private WebElement findElementIfPresent(WebDriver driver, By by){
        try {
            return driver.findElement(by);
        } catch (NoSuchElementException e) {
            return null;
        }
    }

    ...

    driver.findElement(By.name("username")).sendKeys(username);
    driver.findElement(By.name("password")).sendKeys(password);
    driver.findElement(By.name("login")).submit();

    // obtain the div which holds the information
    WebElement errorDiv = findElementIfPresent(driver, By.xpath("//div[@class='errorMsg']"));


    // if the div exists and it has an authentication-problem messages, fail
    if(errorDiv != null && errorDiv.getText().matches("Username or password incorrect. Try again."))
        fail("Username Or Password is Incorrect.");
    }

    // otherwise proceed with additional verifications
    assertEquals(actualTitle, title,"Home is not accessible!");

2）使用javadoc's suggestion并使用findElements(By)返回元素列表。在您的特定情况下，如果列表为空，则验证成功，否则验证失败

    // obtain the list of error divs
    List<WebElement> errorDivs = driver.findElements(By.xpath("//div[@class='errorMsg']"));

    // if there is at east one element present
    if(!errorDivs.isEmpty()){
        // pick first one and use as main failure reason
        fail(errorDivs.get(0).getText());
    }

    // otherwise proceed with additional verifications
    assertEquals(actualTitle, title,"Home is not accessible!");

如果使用Java Selenium Webdriver
