This makes it easy to dynamically create rake tasks. Essentially, this is method_missing for rake! <br /><code> <br />rule "" do |t| <br /> t.name <br /> # ... do something with the name of the task <br />end <br /></code> <br />I experimented by writing a rule that will take a task with the format of controllername_testname and automatically run a single test from the relevant functional or unit test. <br /><code> <br />## <br /># Run a single test in Rails. <br /># <br /># rake blogs_list <br /># => Runs test_list for BlogsController (functional test) <br /># <br /># rake blog_create <br /># => Runs test_create for BlogTest (unit test) <br /> <br />rule "" do |t| <br /> if /(.*)_([^.]+)$/.match(t.name) <br /> file_name = $1 <br /> test_name = $2 <br /> if File.exist?("test/unit/#{file_name}_test.rb") <br /> file_name = "unit/#{file_name}_test.rb" <br /> elsif File.exist?("test/functional/#{file_name}_controller_test.rb") <br /> file_name = "functional/#{file_name}_controller_test.rb" <br /> else <br /> raise "No file found for #{file_name}" <br /> end <br /> sh "ruby -Ilib:test test/#{file_name} -n /^test_#{test_name}/" <br /> end <br />end <br /></code> <br /> <br />Update from : http://mentalized.net/journal/2006/07/28/run_specific_tests_via_rake/ <br />This modified version uses a different syntax (rake test:foo:bar instead rake foo_bar) and regex matching for test names. <br /> <br />Usage <br /><code> <br />$ rake test:blog <br />=> Runs the full BlogTest unit test <br /> <br />$ rake test:blog:create <br />=> Runs the tests matching /create/ in the BlogTest unit test <br /> <br />$ rake test:blog_controller <br />=> Runs all tests in the BlogControllerTest functional test <br /> <br />$ rake test:blog_controller:create <br />=> Runs the tests matching /create/ in the BlogControllerTest functional test <br /></code> <br /> <br />Code <br /><code> <br /># Run specific tests or test files <br /># <br /># rake test:blog <br /># => Runs the full BlogTest unit test <br /># <br /># rake test:blog:create <br /># => Runs the tests matching /create/ in the BlogTest unit test <br /># <br /># rake test:blog_controller <br /># => Runs all tests in the BlogControllerTest functional test <br /># <br /># rake test:blog_controller <br /># => Runs the tests matching /create/ in the BlogControllerTest functional test <br />rule "" do |t| <br /> # test:file:method <br /> if /test:(.*)(:([^.]+))?$/.match(t.name) <br /> arguments = t.name.split(":")[1..-1] <br /> file_name = arguments.first <br /> test_name = arguments[1..-1] <br /> <br /> if File.exist?("test/unit/#{file_name}_test.rb") <br /> run_file_name = "unit/#{file_name}_test.rb" <br /> elsif File.exist?("test/functional/#{file_name}_test.rb") <br /> run_file_name = "functional/#{file_name}_test.rb" <br /> end <br /> <br /> sh "ruby -Ilib:test test/#{run_file_name} -n /#{test_name}/" <br /> end <br />end <br /></code> <br />Do whatever you want with the above code, it’s yours now. <br /> Fri, 28 Jul 2006 18:21:06 GMT http://snippets.dzone.com/posts/show/2337 MattScilipoti (Matt Scilipoti)
