Fast tests mean a fast feedback loop when doing TDD. Let’s make our tests fast with Guard.
A Jasmine spec in CoffeeScript:
describe 'A suite', ->
it 'contains spec with an expectation', ->
expect(true).toBe(true)
Gemfile:
source 'https://rubygems.org'
gem 'jasmine'
gem 'guard'
gem 'guard-coffeescript'
gem 'guard-livereload'
Guardfile:
guard :coffeescript, output: 'javascripts' do
watch(%r{^src/(.*)\.coffee})
end
guard :coffeescript, output: 'spec/javascripts' do
watch(%r{^spec/src/(.*)\.coffee})
end
guard 'livereload' do
watch(%r{^spec/javascripts/.*/(.*)\.js})
watch(%r{^spec/javascripts/(.*)\.js})
watch(%r{^javascripts/.*/(.*)\.js})
watch(%r{^javascripts/(.*)\.js})
end
This compiles CoffeeScript, watches our specs or Javascript files for changes, and reloads our browser automatically.
Start a jasmine server:
rake jasmine
Visit localhost:8888. See the results of the specs.
Change the specs or Javascript files and the browser will automatically reload.
