Converting your tests from Test::Unit to RSpec is a drag when done by hand. This utility intelligently converts them to get you (hopefully) 90% of the way there.

NOTE: This gem is not essentially unusable and is being continually worked on - more of a proof of concept for now.

The gem comes with a thor task that you can use to print out a converted version of any Ruby file containing Test::Unit Code.

$ rspecify cat test_project.rb

This is built on the tree-walking base class RubyTransform::Transformer from the ruby_transform project. The principal transform, which is a composite of other more granular transforms, is RSpecify::Transformer. Here’s how it can be used in conjunction with ruby_parser:

sexp = RubyParser.new.parse(File.read(path))
sexp = RSpecify::Transformer.new.transform(sexp)

emitter = RubyScribe::Emitter.new
emitter.methods_without_parenthesis += ["it", "describe", "context", "should", "should_not"]
emitter.emit(sexp)

• assert_equals

• assert_not_equals

• assert_not_nil

class MyClass < ActiveSupport::TestCase
  def test_should_be_one
    assert_equals something, 1
  end

  def test_should_not_be_one
    assert_not_equals something, 1
  end

  def test_should_not_be_nil
    assert_not_nil something
  end
end

describe MyClass do
  it "should be one" do
    something.should == 1
  end

  it "should not be one" do
    something.should_not == 1
  end

  it "should not be nil" do
    something.should_not be_nil
  end
end
