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!

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.
