Autotest::MerbRspec

This class maps your application’s structure so Autotest can understand what specs to run when files change.

Fixtures are not covered by this class. If you change a fixture file, you will have to run your spec suite manually, or, better yet, provide your own Autotest map explaining how your fixtures are set up.

Finds the proper spec command to use. Precendence is set in the lazily-evaluated method spec_commands. Alias + Override that in ~/.autotest to provide a different spec command then the default paths provided.

Autotest will look for spec commands in the following locations, in this order:

* default spec bin/loader installed in Rubygems
* any spec command found in PATH
# File lib/generators/templates/application/merb_stack/autotest/merb_rspec.rb, line 139
def spec_commands
  [File.join(Config::CONFIG['bindir'], 'spec'), 'spec']
