Note
Don't use reruns as a mean to work around flaky tests. You should always try to fix those instead of rerunning them regularly.
Setup
Configure RSpec to persist the result of your test runs to a file. This is necessary to be able to rerun examples.
Add this to your spec/spec_helper.rb
:
config.example_status_persistence_file_path = 'spec/examples.txt'
Rerun all failed examples using --only-failures
bundle exec rspec --only-failures
(or g rs --only-failures
with geordi) will rerun all examples which failed in the last run.
Rerun a single failed example using --next-failure
bundle exec rspec --next-failure
(or g rs --next-failure
with geordi) will rerun only the first previously failed example.
Once you fixed this spec and it´s green again the next run of g rs --next-failure
will run the next failed example. This will continue until all specs are green and can be very useful if you just implemented your new feature and now need to fix all the specs it broke.
