I want to be able to run a single spec file's tests — for the one file I'm editing, for example. rake spec executes all the specs. My project is not a Rails project, so rake spec:doc doesn't work.
Don't know if this matters, but here is my directory structure.
./Rakefile ./lib ./lib/cushion.rb ./lib/cushion ./lib/cushion/doc.rb ./lib/cushion/db.rb ./spec ./spec/spec.opts ./spec/spec_helper.rb ./spec/db_spec.rb
Or you can skip rake and use the 'rspec' command:
bundle exec rspec path/to/spec/file.rb
In your case I think as long as your ./spec/db_spec.rb file includes the appropriate helpers, it should work fine.
If you're using an older version of rspec it is:
bundle exec spec path/to/spec/file.rb
The raw invocation:
rake spec SPEC=spec/controllers/sessions_controller_spec.rb \
SPEC_OPTS="-e \"should log in with cookie\""
Now figure out how to embed this into your editor.
To run all of your rspec files: rspec
note: you must be in the root of your project
To run one rspec file: rspec 'path_to/spec.rb'
note: replace 'path_to/spec.rb' with your path. Quotation marks optional.
To run one rspec test from one file: rspec 'path_to/spec.rb:7'
note: :7 is the line number where the test starts
If you installed rspec as a plugin rather than as a gem, then you won't have the spec executable.
At any rate, All you need to do is run the file using ruby. The rspec code is clever enough to run the tests for you.
eg:
ruby myclass_spec.rb
http://github.com/grosser/single_test lets you do stuff like..
rake spec:user #run spec/model/user_spec.rb (searches for user*_spec.rb)
rake test:users_c #run test/functional/users_controller_test.rb
rake spec:user:token #run the first spec in user_spec.rb that matches /token/
rake test:user:token #run all tests in user_test.rb that match /token/
rake test:last
rake spec:last
Alternatively, have a look at autotest.
Running autotest in a command window will mean that the spec file will be executed whenever you save it. Also, it will be run whenever the file you are speccing is run.
For instance, if you have a model spec file called person_spec.rb, and a model file that it is speccing called person.rb, then whenever you save either of these files from your editor, the spec file will be executed.
