Travis task to run tests against example solutions

[kytrinyx]

This will require a couple of small things:

• auto-rewriting the require statement to include example instead of the actual file name.
• getting rid of skips (either by deleting the skip lines, or requiring a file that redefines skip to be an empty method).

This may not be the simplest thing to do, I have noticed that the required file is not always the same as the test file... the pattern doesn't hold, for example, for the leap_year exercise. They have leap_test.rb but the required file is year, rather than leap... This makes sense for the exercise, but not for matching for automated testing.

[kytrinyx]

Yeah, that's part of the reason why I haven't done it yet.

I would be OK with changing the name of the require, actually, if that would help, though it pains me a bit to have a leap.rb that defines a Year constant (another reason why I've been putting this off).

Another option would be to add a marker to the line to be replaced as a trailing comment. That would allow us to have any name for the file and still recognize it consistently.

Whatever the plugin says, it could be thusly done (pseudo-code):

begin
  require '_test'  
rescue LoadError
  'File not created yet, using example.rb'
  require 'example.rb'
end
class Minitest::Test
  def skip ; end
end

The last monkey patches the skip method so that all tests run. The prior makes it so that example.rb that is required anyway per the API is accounted for. The consistency is provided by example.rb

[kytrinyx]

Oh, yeah, that would totally work.

[kotp]

I believe this has been effectively addressed...

Yepp. Thanks!
