RSpec: run a single spec (Example or ExampleGroup)
RSpec allows you to mark a single Example/ExampleGroup so that only this will be run. This is very useful when using a test runner like guard.
Add the following config to
RSpec.configure do |config| # These two settings work together to allow you to limit a spec run # to individual examples or groups you care about by tagging them with # `:focus` metadata. When nothing is tagged with `:focus`, all examples # get run. config.filter_run_including :focus => true config.run_all_when_everything_filtered = true ... end
Now you can mark a single Example/ExampleGroup with the "focus"-tag so only the tagged spec will be run:
describe SomeClass do it 'does great stuff', :focus do ... end ... end
Alternatively you can prepend
f to any of
context which will result in
describe SomeClass do fit 'does great stuff' do ... end ... end
Analogously you can exclude Examples or Example Groups from being run by prepending
xcontext). Good thing is that those will be shown as
pending in the RSpec output, so you won't be tempted to commit excluded Examples to source control.
