Feature: minitest support

  minitest is supported by Bogus both with the classic assert-style syntax and the minitest/spec expectation syntax.

  Background:
    Given a file named "library.rb" with:
    """ruby
    class Library
      def self.books
      end

      def checkout(book)

      def return_book(book)

    end

    Given a file named "book_index.rb" with:
    """ruby
    class BookIndex
      def self.by_author(author)
        Library.books.select{|book| book[:author] == author}
      end
    end
    """

    Given a file named "student.rb" with:
    """ruby
