Added support TestUnit

[ordinaryzelig]

Since it's so easy, might as well add support for TestUnit.

Could also send a pull request to https://github.com/sunspot/sunspot to add this gem to the Help and Support, Tutorials and Articles section. This seems to be a cleaner solution than the article they list about testing with TestUnit by Type Slowly, which is how I found this gem in the first place.

I'm sorry for commenting on this one so so very late, but this will spin up solr on every startup, which can be really a nuisance when you want to run single tests that do not use solr.

I also find it confusing to have SunspotTest.stub, just to be contradicted right the next line with #setup_solr that unstubs the session.

My approach nowadays is:

# test_helper.rb

require "sunspot_test"
SunspotTest.stub

# since Test::Unit doesn't have the privileges of tags, I use a simple helper:

class ActiveSupport::TestCase # or MiniTest::Unit::TestCase or Test::Unit::TestCase

  def with_sunspot
    SunspotTest.setup_solr
    Sunspot.remove_all!
    Sunspot.commit
    yield
    SunspotTest.stub
  end

end

in my tests I make simple usage of it:

test "search works" do
  with_sunspot do
    create_model_records_that_will_be_indexed
    Model.search # works as expected
  end
end

test "this does not use search" do
  create_model_records_that_will_not_be_indexed
end
