Robot Framework - Case sensitive - testing

Question

I need to know if there is a workaround on this error:
When I use Keywords like:
Location Should Be
Location Should Contain
(Which are both part of the Selenium2Library.)
I get this error:
"Location should have been 'http://www.google.pt' but was 'http://WwW.GooGLe.Pt'
I think that is because robot framework is natively case sensitive when comparing strings.
Any help?

Question edited to clarify some subjects.

Answer 1

Luckily Robot Framework allows for keywords to be written in python.
MyLibrary.py
def Compare_Ignore_Case(s1, s2):
if s1.lower() != s2.lower():
return False
else:
return True
def Convert_to_Lowercase(s1):
return s1.lower()
MySuite.txt
| *Setting* | *Value* |
| Library | ./MyLibrary.py |
| *Test Case* | *Action* | *Argument*
#
| T100 | [Documentation] | Compare two strings ignoring case.
| | Compare Ignore Case | foo | FOO
#
| T101 | [Documentation] | Compare two strings where one is a variable.
# Should be Get Location in your case.
| | ${temp}= | MyKeyword that Returns a String
| | Compare Ignore Case | foo | ${temp}
I have not used the Selenium library, but the example in T101 should work for you.

Just in case someone else wants this:
Location should be '${expectedUrl}' disregard case
${currUrl} get location
${currUrl} evaluate "${currUrl}".lower()
${expectedUrl} evaluate "${expectedUrl}".lower()
should be equal ${currUrl} ${expectedurl}
Location should contain '${expected}' disregard case
${currUrl} get location
${currUrl} evaluate "${currUrl}".lower()
${expected} evaluate "${expected}".lower()
should contain ${currUrl} ${expected}
