Hello,
I have the following step for checking that a validation message is
displayed on screen:
Then /^(.+) should be displayed$/ do |error|
msg = @browser.ul(:class, 'validation-summary-errors').li(:text,
error)
#pp msg.text
msg.should_not == nil
end
I run scenario with examples table which contains expected error
messages. If I put wrong error message and pp line in step is commented
out as shown I get green result from Cucumber, which is wrong. When I
uncomment pp line I get exception
Unable to locate element, using :text, "BOOOOOOOOOO"
(Watir::Exception::UnknownObjectException)
./features/step_definitions/customer_details_steps.rb:47:in `/^(.+)
should be displayed$/'
features/customer_details_full.feature:40:in `Then <Error> should be
displayed'
And step is shown as Red in Cucumber as it should.
Is this a bug in Cucumber or am I missing something?
I'm not sure if I fully understand the situation... Let me try to
summarize. The exception being raised seems to be coming from the first
line in the step, is that correct? (So, having the "msg.should_not ==
nil" seems redundant.) To sum it up, when you have a pp call after you
have watir locate the element then no exception appears to be thrown.
However, without the pp call the exception is thrown, or at least
reported by Cucumber. Is that right?
From my current understanding there could be two things going on.
A) Watir is not being consistent in when it throws an exception. OR
B) Cucumber is not being consistent on how it handles and reports
exceptions.
Try catching the Watir exception yourself to see if the problem is with
Watir not raising an exception. So something like...
Then /^(.+) should be displayed$/ do |error|
begin
msg = @browser.ul(:class, 'validation-summary-errors').li(:text,
error)
rescue Exception =>e
puts "This was raised: #{e.inspect}"
raise e
end
#pp msg.text
end
If it appears that Cucumber is not handling the exceptions consistently then
open up a ticket for it. [1]
