Selenium WebDriver 忽略 JAVA 中编写的条件逻辑

Question

这是一个简单的 sign-in 脚本，我正在运行 Firefox 中使用。我想做的是在 sign-in 成功或失败时打印一条消息。我给错了 user/pass 得到错误（根据网站验证它是正确的）。

page-title 元素仅在用户 logged-in 成功时显示。同样，error-msg 元素仅在用户不是 logged-in.

时显示

WebDriver driver = new FirefoxDriver();
    String baseUrl = "http://www.example.com";
    String actualTitle;

    // Launch Firefox and direct it to the Base URL
    driver.get(baseUrl);
    driver.manage().timeouts().implicitlyWait(45, TimeUnit.SECONDS);

    // Maximize the browser window
    driver.manage().window().maximize();

    // Get the actual value of the title
    actualTitle = driver.getTitle();


    driver.findElement(By.linkText("Signin")).click();

    WebElement email = driver.findElement(By.id("email"));
    email.click();
    email.sendKeys("abc@example.com");

    WebElement pass = driver.findElement(By.id("pass"));
    pass.click();
    pass.sendKeys("abc123456");

    driver.findElement(By.id("send2")).click();



    // Variables for Dashboard & Error Title
    WebElement dashboardTitle = driver.findElement(By.className("page-title"));
    WebElement loginFailed = driver.findElement(By.className("error-msg"));

    if(loginFailed.getText().contains("Invalid login or password."))
        System.out.println("Test passed but login failed.");
    else if(dashboardTitle.getText().contains("My Dashboard"))
        System.out.println("Logged in successfully.");
    else if(dashboardTitle.getText().contains("Account Information"))
            System.out.println("Logged in successfully.");
    else
        System.out.println("You're not logged-in.");

    System.out.println("The title of current page is: "+actualTitle);
    driver.close();
    driver.quit();

User/Pass 不正确，所以 'IF' 条件应该运行但实际上它给我错误，找不到其他元素 (page-title)。

如果我删除其他条件（从 IF 语句），那么脚本运行ning 没有任何问题。

我希望脚本运行并搜索这两个元素，如果它只找到一个元素（它应该是），那么它应该显示它的结果而不是给我错误说其他元素不是找到了。

Answer 1

使用 try-catch 块。

....
....
driver.findElement(By.id("send2")).click();

try {
    WebElement dashboardTitle = driver.findElement(By.className("page-title"));
    System.out.println("Logged in successfully.");
    /* Continue code for correct login credentials
     *
     */
} catch(NoSuchElementException e) {

}

try {
    WebElement loginFailed = driver.findElement(By.className("error-msg"));
    System.out.println("Test passed but login failed.");
    /* Continue code for incorrect login credentials
     *
     */
} catch(NoSuchElementException e) {

}

System.out.println("The title of current page is: "+actualTitle);
driver.close();
driver.quit();
....
....

使用下面的方法来查找一个web元素，这应该可以帮助你等待并找到元素，如果没有找到元素它会捕获异常并且return null 或者一个WebElement。

public WebElement waitAndGetElement(WebDriver driver, By by, int waitTimeInSeconds) {
   try {
        return new WebDriverWait(driver, waitTimeInSeconds).until(ExpectedConditions.visibilityOfElementLocated(by)); 
   } catch(Exception e) {
        e.printStackTrace();
   }
   return null;
}

示例：

WebElement loginFailed = waitAndGetElement(driver, By.className("error-msg"), 5);

if(loginFailed != null && loginFailed.getText().contains("Invalid login or password."))
    System.out.println("Test passed but login failed.");

使用此代码解决了我的问题：

Boolean exist;
    if(exist = driver.findElements(By.className("page-title")).size() == 0){
        WebElement errorMessage = driver.findElement(By.className("error-msg"));

        if(errorMessage.getText().contains("Invalid login or passwords.")){
            System.out.println("Test passed but login failed.");
        }
        else
            System.out.println("error-msg class found but different message in it.");
    }

    else{
        WebElement dashboardTitle = driver.findElement(By.className("page-title"));
        if(dashboardTitle.getText().contains("Account Information"))
            System.out.println("Logged in successfully.");
        else
            System.out.println("LOGGED IN");
    }
