更改密码测试用例 Selenium - 调试
Change Password Test Cases Selenium - Debug
下面是我写的更改密码的测试。
@测试
public void changePassword() throws IOException, InterruptedException {
Login();
driver.findElement(By.xpath(".//*[@id='wrapper']/div[1]/div[2]/div/div/ul/li[3]/a")).click();
driver.findElement(By.xpath(".//*[@id='wrapper']/div[1]/div[2]/div/div/ul/li[3]/ul/li[3]/a")).click();
driver.findElement(By.xpath(".//*[@id='change-password']/div[1]/div/input")).sendKeys("abcd");
driver.findElement(By.xpath(".//*[@id='Users_password']")).sendKeys("xyz123456");
driver.findElement(By.xpath(".//*[@id='repassword']")).sendKeys("xyz123456");
driver.findElement(By.xpath(".//*[@id='change-password']/div[4]/div/input")).click();
}
}
下面是我遇到的错误，我检查过 Xpath 是正确的，仍然遇到这个错误 -
org.openqa.selenium.NoSuchElementException: Unable to locate element: {"method":"xpath","selector":".//*[@id='change-password']/div[1]/div/input"}

我的问题是 -
1. 上面的代码有什么问题，当我执行此代码时，它会将我带到更改密码屏幕。
2. 以上方法是测试更改密码功能的最佳方法吗？
3. 是否还有更多测试场景可以推荐我包含以及如何包含？
以下是您问题的答案：
What is wrong in above code:
您构建的xpaths，例如.//*[@id='wrapper']/div[1]/div[2]/div/div/ul/li[3]/a、.//*[@id='wrapper']/div[1]/div[2]/div/div/ul/li[3]/ul/li[3]/a 和 .//*[@id='change-password']/div[1]/div/input 是包含 index 的绝对 xpaths。因此它们是 brittle 和 vulnerable。可以考虑构造unique logical xpath.
Is above way the best way to test change password functionality?:
我认为这方面没有最佳实践。因为这实际上取决于您要解决的问题。但绝对在对文本字段使用 sendKeys("abcd") 方法之前，您应该首先考虑使用 clear() 方法。
- 当有
NoSuchElementException: Unable to locate element时，我们应该考虑用适当的ExpectedConditions诱导ExplicitWait，这样Selenium就可以定位到元素至少。
如果这回答了您的问题，请告诉我。
首先尝试添加 HTML 代码片段，这样定位器就可以用更冗余的方式编写。
2、使用一些等待机制来正确加载页面。在您的情况下，您正在单击 link 并尝试在更改密码输入字段中输入数据，由于页面未正确加载和 Selenium 尝试在更改密码字段中输入值而导致出现异常.
对于简单的解决方案，您可以使用隐式等待，它会起作用
driver.manage().timeouts().implicitlyWait(5, TimeUnit.SECONDS);
