How to test with changing xpath

Question

I am trying to automatate login of a web applicatioon. The address is

https://portal.bugfinders.com

I cannot find xpath of user name or password field. It generates a unique alue every time. How can I automate this site?

Answer 1

I checked the website, you can try using name or id right?

 

For usename, By.id("un") or By.name("un");

For password, By.id("pw") or By.name("pw");

For login you can use By.xpath("//input[type=\"submit\"]");

 

Try and let me know.

You can try using
For username, By.xpath("//*[@id=\"un\"]");
For password, By.xpath("//*[@id=\"pw\"]");
For login, By.xpath("//*[@value=\"Login\"]")

Try and let me know.
