So I want to check that the website isn’t allowing anyone to do something, basically If the test case can’t do something it should pass. I don’t know how to do that and I couldn’t find anything like that anywhere else.

Hi @Tigetiiger,

[Run Keyword And Expect Error](https://robotframework.org/robotframework/latest/libraries/BuiltIn.html#Run%20Keyword%20And%20Expect%20Error) is what you are probably after. You can even make it fail if it doesn’t get the error you were expecting to get but some other different error.

Dave.
