RSpec Tags provide an easy way to run specific tests in your spec
files. By default, RSpec will run all tests in the spec files that it
runs, but you might only need to run a subset of them. Let’s say that
you have some tests that run very quickly and that you’ve just made a
change to your application code and you want to just run the quick
tests, this code will demonstrate how to do that with RSpec Tags.
You will see this output −
Run options: include {: slow = >true}
You will see this output −
describe "How to run specific Examples with Tags" do it 'is a slow test', :slow = > true do sleep 10 puts 'This test is slow!' end it 'is a fast test', :fast = > true do puts 'This test is fast!' end endNow, save the above code in a new file called tag_spec.rb. From the command line, run this command: rspec --tag slow tag_spec.rb
You will see this output −
Run options: include {: slow = >true}
This test is slow! . Finished in 10 seconds (files took 0.11601 seconds to load) 1 example, 0 failuresThen, run this command: rspec --tag fast tag_spec.rb
You will see this output −
Run options: include {:fast = >true} This test is fast! . Finished in 0.001 seconds (files took 0.11201 seconds to load) 1 example, 0 failuresAs you can see, RSpec Tags makes it very easy to a subset of tests!
