Guard::JestRunner allows you to automatically run jest when you change a Javascript/ES6 file.
Unlike guard-jest, this guard runs just as directed by your Guardfile, which allows you to use it in a group and use a Red-Green-Refactor process.
Add this line to your application's Gemfile:
gem 'guard-jest_runner'And then execute:
$ bundle
Or install it yourself as:
$ gem install guard-jest_runner
Please read Guard usage doc.
For a typical Rails app with webpack:
guard :jest do
watch(%r{app/javascript/(.+)\.js$}) { |m| "spec/javascript/#{m[1]}.test.js" }
watch(%r{spec/javascript/.+\.js$})
end(Recommended) pair up with guard-eslint to get a Red-Green-Refactor process:
group :red_green_refactor_js, halt_on_fail: true do
guard :jest_runner do
watch(%r{app/javascript/(.+)\.js$}) { |m| "spec/javascript/#{m[1]}.test.js" }
watch(%r{spec/javascript/.+\.js$})
end
guard :eslint, formatter: 'codeframe' do
watch(%r{app/javascript/(.+)\.js$}) { |m| ""}
watch(%r{spec/javascript/(.+)\.js$})
end
