[FIXED] Robot Framework : Keyword 'login_resources.Open Browser' expected 0 arguments, got 2

Issue

I am new to Robot framework and would like to practice it. I have encountered this error while trying Data driven testing. I think the problem is the resources but I don't know what's wrong. I have searched for some answers but none of it solved it.

Please help me. Below is my code.

Solution

Robot framework is case insensitive. Now you have 2 keywords that are named open browser. One uses 0 arguments and the other 2. now you have to specifi the library when using the keyword.

SeleniumLibrary.open browser

Or use another name for your keyword Open Browser.
