RSpec: top failing specs report
You just made a big change that broke a lot of tests and you would love to know which specs have the most failing tests? Here is how to add a breakdown of the files with the most failing specs.
Create a spec/support/top_failing_specs.rb:
RSpec.configure do |config|
failed_examples = {}
config.after(:each) do |group|
if group.example.instance_variable_get("@exception")
failed_examples[group.example.metadata[:file_path]] ||= 0
failed_examples[group.example.metadata[:file_path]] = failed_examples[group.example.metadata[:file_path]] + 1
end
end
config.after(:suite) do
if failed_examples != {}
puts '------------------------------------------------'
puts ' Top failing specs '
puts '------------------------------------------------'
failed_examples.sort_by {|k,v| v}.reverse.each do |k,v|
puts "#{v.to_s.rjust(3)} | #{k}"
end
puts '------------------------------------------------'
end
end
end
Example of output:
------------------------------------------------
Top failing specs
------------------------------------------------
18 | ./spec/models/my_model_spec.rb
4 | ./spec/models/your_failing_model_spec.rb
Please note that if you have a shit load of failing tests, that will work better with some custom RSpec formatter like Fuubar.
Go fix your tests now!
