java - Java 负面场景的 Selenium 断言

Question

我试图在 selenium 中断言 gmail 登录的负面测试用例，但最终出现异常。谁能提出问题是什么？

 @Test(dataProvider="LoginData")
public void testMethod(String email,String password) throws InterruptedException{
            browser.findElement(By.id("Email")).clear();
            browser.findElement(By.id("Email")).sendKeys(email);
            browser.findElement(By.id("Passwd")).sendKeys(password);
            browser.findElement(By.id("signIn")).click();
            browser.wait(30000);
            assertTrue(browser.getPageSource().contains("The username or password you entered is incorrect."));

}

生成异常

获取整个页面源代码来仅测试一小段错误文本是不可行的。最好的方法是找到该元素(当然你希望我首先确定该元素是否存在)并对其执行 .contains() 。因为您没有提供任何 html 我不确定如何找到目标元素。但您肯定想使用FindElement()。类似下面的代码块可能是您想要的

@Test(dataProvider="LoginData")
public void testMethod(String email,String password) throws InterruptedException{
    WebDriver browser = new ChromeDriver();
    browser.findElement(By.id("Email")).clear();
    browser.findElement(By.id("Email")).sendKeys(email);
    browser.findElement(By.id("Passwd")).sendKeys(password);
    browser.findElement(By.id("signIn")).click();
    browser.wait(30000);

    try{
        String error = browser.findElement(By.id("Your id")).getText();
        assertTrue(error.contains("The username or password you entered is incorrect."));

       }catch (NoSuchElementException e){
         //something else
       }
}
