Overview

Autotest continuously scans the files in your project for changes and runs the appropriate tests. Test failures are run until they have all passed. Then the full test suite is run to ensure that nothing else was inadvertantly broken.

If you want Autotest to start over from the top, hit ^C once. If you want Autotest to quit, hit ^C twice.

Rails:

The autotest command will automatically discover a Rails directory by looking for config/environment.rb. When Rails is discovered, autotest uses RailsAutotest to perform file mappings and other work. See RailsAutotest for details.

Plugins:

Plugins are available by creating a .autotest file either in your project root or in your home directory. You can then write event handlers in the form of:

Autotest.add_hook hook_name { |autotest| ... }

The available hooks are listed in ALL_HOOKS.

See example_dot_autotest.rb for more details.

If a hook returns a true value, it signals to autotest that the hook was handled and should not continue executing hooks.

Naming:

Autotest uses a simple naming scheme to figure out how to map implementation files to test files following the Test::Unit naming scheme.

  • Test files must be stored in test/

  • Test files names must start with test_

  • Test class names must start with Test

  • Implementation files must be stored in lib/

  • Implementation files must match up with a test file named test_.*implementation.rb

Strategy:

  1. Find all files and associate them from impl <-> test.

  2. Run all tests.

  3. Scan for failures.

  4. Detect changes in ANY (ruby?. file, rerun all failures + changed files.

  5. Until 0 defects, goto 3.

  6. When 0 defects, goto 2.

    .autodiscover  ⇒ Object 
  

  

  




  

    

Automatically find all potential autotest runner styles by searching your loadpath, vendor/plugins, and rubygems for “autotest/discover.rb”. If found, that file is loaded and it should register discovery procs with autotest using add_discovery. That proc should return one or more strings describing the user’s current environment. Those styles are then combined to dynamically invoke an autotest plugin to suite your environment. That plugin should define a subclass of Autotest with a corresponding name.



Process:


  1. 

    All autotest/discover.rb files loaded.
    

  2. 

    Those procs determine your styles (eg [“rails”, “rspec”]).
    

  3. 

    Require file by sorting styles and joining (eg ‘autotest/rails_rspec’).
    

  4. 

    Invoke run method on appropriate class (eg Autotest::RailsRspec.run).
    




Example autotest/discover.rb:



Autotest.add_discovery do
  "rails" if File.exist? 'config/environment.rb'
end

For example, if test_helper.rb is modified, rerun all tests:



at.add_mapping(/test_helper.rb/) do |f, _|
