In RSpec you can tag examples or example groups with any tags you like simply by saying
describe ReportCreator, slow: true do
# ..
end
describe ReportCreator do
it 'generates reports', slow: true do
# ...
end
end
You can then only run examples with these tags.
rspec --tag slow
rspec -t slow
# Using the parallel_tests gem
rake "parallel:spec[,,--tag slow]"
Or you can run all examples except the ones with a certain tag:
rspec --tag ~slow # note the ~
rspec -t ~slow
# Using the parallel_tests gem
rake "parallel:spec[,,--tag ~slow]"
You can also assign values to tags, and only run or exclude those tags where the values match a given string.
describe ReportCreator do
it 'generates reports', speed: 'slow' do
# ...
end
end
rspec . --tag speed:slow # Only run examples tagged with speed: 'slow'
rspec . --tag ~speed:slow # Run examples except the ones tagged with speed: 'slow'
You can use the tags for hooks and includes, too.
RSpec.configure do |config|
config.before(:each, slow: true) do
# Do one thing here
end
end
RSpec.configure do |config|
config.include SlowHelpers, type: :slow
end
Note that RSpec will, although it prints your tags inclusion/exclusion config before the suite run, ignore tag config when you pass it a spec file with a line number. That's even when the line number references a describe or context block, where only some examples should be excluded.
