Bob Silva posted Testing Gotchas in Rails in mid-October. I had fallen across this error myself a few times.
Well, today I had a huge code base I needed to check. I wrote the following Rake task:
lib/tasks/find_missing_fixtures.rake
1 # Find missing fixtures declarations from Rails tests 2 # Code by Francois Beausoleil (francois@teksol.info) 3 # Released in the public domain. Do as you wish. 4 desc "Finds missing fixtures declarations from your tests" 5 task :find_missing_fixtures do 6 state = :find_test_case 7 test_case = nil 8 9 Dir['test/*/*_test.rb'].each do |file| 10 File.open(file, 'r') do |f| 11 f.each do |line| 12 case state 13 when :find_fixture 14 case line 15 when /def test_/ 16 printf "%s: %s\n", file, test_case 17 state = :find_test_case 18 when /fixtures/ 19 state = :find_test_case 20 when /class (\w+) < Test::Unit::TestCase$/ 21 test_case = $1 22 state = :find_test_case 23 end 24 25 when :find_test_case 26 case line 27 when /class (\w+) < Test::Unit::TestCase$/ 28 test_case = $1 29 state = :find_fixture 30 end 31 end 32 end 33 end 34 end 35 end
Run it like this:
1 $ rake find_missing_fixtures 2 (in D:/wwwroot/wpul.staging.teksol.info) 3 test/unit/name_test.rb: NameTest 4 test/unit/application_helper_test.rb: ApplicationHelperTest 5 test/unit/application_helper_test.rb: ApplicationHelperTruncationTest
Why do I report both the file and TestCase name ? Because I put more than one TestCase per test file, as I reported in Test fixtures and behavioral testing
Of course, if I could do away with fixtures altogether…
