Trailblazer::Core::Utils

Convert Activity tests to Operation tests

In order to show users both Activity and Operation tests, we have a converter. This implies converted tests are written in a specific style.

We currently don't use a bin/ command.

require "trailblazer/core"
Trailblazer::Core.convert_operation_test("test/docs/model_test.rb")
Trailblazer::Core.convert_operation_test("test/docs/each_test.rb")
