As well as using Autotest to run Cucumber scenarios I have also been looking into integrating lower level test into the Autotest cycle.
My first attempt at this is a small module to run Javascript Lint on all the javascript files within a project any time any file changes.
The module below hooks in to Autotest just before the tests are normally run. It runs javascript lint over all the *.js files in the project, outputs the results to the autotest results object and the standard output, and finally fires a new ran_javascript_lint hook
Errors and warnings found by Javascript Lint will also be notified through Growl (if Growl and autotest-growl are installed). If there are no errors or warnings than no Growl notification is shown. This keeps distracting popups to a minimum.
Installing Autotest Javascript Lint
First up, download Javascript Lint. Extract the jsl executable to lib/autotest/ within your project.
Copy the code below to lib/autotest/javascript-lint.rb within your project (the same directory where you have the jsl execuatable).
javascript-lint.rb
# Run Javascript Lint as part of autotest # Supports Growl notifications if using autotest-growl # # Version 1.0 require 'autotest' module Autotest::JavascriptLint @@js_dir = '' @@jsl_dir = File.dirname(__FILE__) + '/' @@config_file = '' def self.js_dir=(string) @@js_dir = string end def self.jsl_dir=(string) @@jsl_dir = string end def self.config_file=(string) @@config_file = string end Autotest.add_hook :run_command do |at| # run javascript lint results = `#{@@jsl_dir}jsl -conf "#{@@config_file}" -process "#{@@js_dir}*.js" +recurse` puts results at.results = [] if at.results.nil? at.results.concat(results.split("\n")) at.hook :ran_javascript_lint end end module Autotest::Growl @@show_js_lint_success = false def self.show_js_lint_success=(bool) @@show_js_lint_success=bool end # Growl results of Javscript Lint Autotest.add_hook :ran_javascript_lint do |autotest| gist = autotest.results.grep(/\d+\s+error.*,\s+\d+\s+warning.*/).join(" / ").strip() if gist == '' growl @label + 'Cannot run javascript lint.', '', 'error' else if gist =~ /[1-9]\d*\s+(error)/ growl @label + 'Lint: Some files have errors.', gist, 'failed' elsif gist =~ /[1-9]\d*\s+(warning)/ growl @label + 'Lint: Some files have warnings.', gist, 'pending' elsif @@show_js_lint_success growl @label + 'Lint: All files are clean.', gist, 'passed' end end false end end |
Then add Autotest Javascript Lint to your .autotest configuration file within the base of your project.
require 'lib/autotest/javascript-lint' |
To Do
This could be packaged as a gem for easy installation, and it could possibly be modified to only run over changed files.
