7/25 Opscode Code Review


#1

We’ve been a bit remiss in not communicating well about the importance
of testing and what we’re doing. I want to write up a wiki page but I
keep putting it off. What’s most important right now are the RSpec
tests that are in the spec/ folder of the Chef, Ohai, and some of the
smaller projects. When merging a contribution we rebase the topic
branch against master and then run the spec tests. If they fail, we
usually go back and reopen the ticket without merging to master. Once
we merge to master and push it up to github, it triggers our Jenkins
CI to run the spec tests against Ruby 1.8 and 1.9 on Linux and Ruby
1.9 on Windows. If one of these tests fail, we have a few options.
Usually we fix the tests ourselves rather than revert. Sometimes we’ll
reach out the contributor to see if they can fix it right away.

These tests got crufty recently and I just finished going back through
and getting them all passing. There are a couple failures that aren’t
occurring on our CI but sometimes do on a workstation. I think some of
them have to do with data leaking from one test to the next. You can
sometimes see this by running rspec against a single file, then all of
the unit tests, then running ‘rake spec’ which also runs some
functional tests.

If you haven’t run the spec tests before, please do so now. Throw it
off, see how it works.

The Chef unit tests are run from inside of the chef directory. Here
are a few examples:

/src/chef/chef rake spec # Runs both the functional tests and the unit tests /src/chef/chef rake spec:unit # Runs just the unit tests
/src/chef/chef rake functional # Runs just the function tests /src/chef/chef rspec -cb spec/unit/* # Runs just the unit tests,
with a nice color output and provides a full backtrace on failure
/src/chef/chef $ rspec -cb spec/unit/cookbook_loader_spec.rb # The
same as above but against a single set of tests

If you’re having trouble, make sure you’re running a recent version of
rspec. Using bundler usually helps, despite being magical duct tape.

I’ll be merging the backlog into chef/master shortly. Then we’ll be
forking an 0.10-stable branch in preparation for incoming Chef 11
work.

These are the combined notes from a Cook review we did on Tuesday
