[Pkg-giraffe-discuss] autopkgtest in kopano-webapp

[Carsten Schoenert]

Hi,

I tried to play around with the non working autopkgtest in kopano-webapp.

In preparation for 3.5.0 I added a missing 'need-root' to the control
file due the needed database setup. But then you get a warning about
phantomjs isn't supported any more, you need to work now in headless
mode. After some searching what's needed to get changed for this I got
this now working by this change.

The current implementation can be reduced later a bit for sure, it's
mostly some dirty C&P for now to get it working. It working ... but now
we get a Python Traceback due some left over coding issue due changes to
Python?

The problem is here:

>     def find_element_by_(self, type, name):
>         try:
>             find_element_by_ = getattr(self.driver, 'find_element_by_%s', type)
>             return find_element_by_(name)

As far I understand 'find_element_by_' should be expanded by 'name' and
if I change this to

>             find_element_by_ = getattr(self.driver, 'find_element_by_' + type)

this is working for 'username' and 'password' but not later for
preparing and sending an mail.

Someone has some quick fix I can try? :-)
