Unit Tests

Hi, If you have (say) 50 unit tests how do you run them all and check that there are no failures. I have a script that runs all the tests but it is difficult to spot failures in the mass of output....

Just plain 'rake' should run all your tests and count up the
successes/failures

For running all test files, run 'rake' command. For more specific tests:

rake test # Test all units and functionals rake test:functionals # Run the functional tests in test/functional rake test:integration # Run the integration tests in test/integration rake test:plugins # Run the plugin tests in vendor/plugins/**/test (or specify with PLUGIN=name) rake test:recent # Test recent changes rake test:uncommitted # Test changes since last checkin (only Subversion) rake test:units # Run the unit tests in test/unit

You can see available rake test tasks, by running 'rake -T test' from your project directory.

You can also run a test file with ruby:

ruby test/unit/model_test.rb

Or even just a test method by passing it's name to -n switch:

ruby test/unit/model_test.rb -n test_method

Thanks that is exactly what I needed. I was sure there must be a better way than a script! G

A tip if you want nicely colored and formatted output:

        gem install turn         gem install facets

And then in test_helper.rb:

        require 'turn'

It is somewhat more verbose than the default test/unit output, so it's a matter of taste. I'm not sure the coloring works on windows though, the formatting is still good.
