java - Selenium Web 驱动程序 Java 代码无法从存储在包文件夹下的 src 文件夹中的 "Object.Properties"文件中读取 xpath/Class id/link id

Question

我在 Eclipse 中使用 Selenium Web Driver 和 Java，我试图从存储在包文件夹下的 src 文件夹中的“Object.Properties”文件中读取 xpath/Class id/link id，并从数据库填充测试数据。但是，从以下属性文件脚本读取第二个属性后，不再读取电子邮件、密码和提交的属性。我无法弄清楚为什么脚本不读取这些属性。

我的脚本将使用存储在包文件夹下的 src 文件夹中的“Object.Properties”文件中的 xpath/Class id/link id 来识别 Web 字段、按钮、链接。对于网页字段脚本将从数据库中获取测试数据并将其填充到网页上的特定字段中。

以下属性存储在“Object.Properties”文件中，该属性文件存储在包文件夹下的 src 文件夹中:

URL = http://web.com/user-portal
ClickOnLoginLink = //*[@id='app']/div/main/section/ul/li[1]/a
Email = //input[@name='username']
Pwd = //input[@name='password']
Submit = //button[@name='loginButton']

以下失败异常显示:

org.openqa.selenium.NoSuchElementException: Unable to locate element: {"method":"xpath","selector":"//input[@name='username']"}
Command duration or timeout: 12 milliseconds

Answer 1

实际上，我发现我没有给出优先级，我已经提供了数据库连接方法信息，以便当脚本运行时，脚本遵循 TestNG 框架来执行测试，并且脚本开始执行 Test(priority=1 )，测试(优先级= 2)等等...对于数据库连接，我在启动数据库连接方法之前只提供了“测试”。我还应该将数据库连接方法优先考虑为测试(优先级= 2)。因此，只需优先考虑数据库连接方法即可解决我的问题。
