1168448 - test_homescreen_column_layout.py: "TypeError: int() argument must be a string or a number, not 'NoneType'"

Status: RESOLVED FIXED

(Firefox OS Graveyard :: Gaia::UI Tests, defect)

Description

[Oliver Nelson [:oliverthor]]

Description:
test_homescreen_column_layout is encountered a common exception near the end of it's test after switching the column layout from 4 to 3. On checking to verify if the value of attribute 'cols' is equal to "4", the test fails in interpreting the value. The behavior that is being tested here is not failing, rather the method in which the value is checked.

4) Change the value of "Homescreen Columns" from 'Three' to 'Four'

I could reproduce this one time on my device (the first time I tried). Afterwards, I couldn't reproduce it anymore.
Anyway, this would fix it.
