I'm using cucumber, rails3, rspec2 and autotest. I'm trying to figure out why my features are infinitely looping. I suspect it some file being changed during the tests but I'm not sure which one. I've added some exceptions to my .autotest
with no dice.
Are there any steps I can take to troubleshoot this problem?
It'd be cool if I could see what files are triggering a rerun or, at run time, what files are being watched/not watched.
here's my .autotest contents
require 'autotest/growl'
Autotest::Growl::clear_terminal = false
# Skip some paths
Autotest.add_hook :initialize do |autotest|
%w{.git .DS_store db log tmp rerun.txt}.each { |e| autotest.add_exception(e) }
end
Ok, so I figured it out. I dove into autotest's source to get a better understanding of what was going on. It creates a Regexp.union out of all the exceptions and ignores files who's relative paths match the complied expression.
To better understand the bug I added everything in my project's directory to .autotest
except ./app
, ./lib
, ./public
, ./script
, ./spec
and ./features
. Something like this:
# .autotest - to troubleshoot
Autotest.add_hook :initialize do |at|
at.add_exception(%r{^\./\.git})
...
at.add_exception(%r{^\./db})
...
at.add_exception(%r{^\./rerun.txt})
...
end
When I did this I didn't get an infinite loop. After that I just began to comment out each exception. Turns out, the only file I had to manually ignore was Gemfile.lock
. For some reason this is either being changed or confusing autotest to the point where it makes cucumber loop.
Thus, this .autotest
solved the problem:
# .autotest - to fix
Autotest.add_hook :initialize do |at|
# Gemfile.lock is causing cucumber to run infinitely. Don't watch it.
at.add_exception(%r{^\./Gemfile.lock})
end
I'm going to report on the cucumber list to let them know they should add that to the built in autotest exceptions.
Just wanted to say thanks. Turns out, for me, it was the log directory. My .autotest
file looks like this.
# .autotest
Autotest.add_hook :initialize do |at|
# Log directory is causing cucumber to run infinitely.
at.add_exception(%r{^\./log})
end
For reference, see "Customizing Autotest Behavior" in http://github.com/aslakhellesoy/cucumber/wiki/Autotest-Integration, which talks about the infinite loop problem.
In Linux/Unix you can use the command:
$ find . -mmin -5
to figure out which files were modified in the last 5 minutes (or whatever lapse is appropiate). This can greatly help in finding the file which is triggering infinite loop. Then add the exception as explained in the other answers.
In my case, the culprit was webrat.log
.
It's worth noting that you can pass -v to autospec/autotest and it will print out what triggered it to run.
