I am using rspec-mock for test-driven-development.
I am starting implementing a single class and mocking/stubbing the other
classes using rspec-mock. Mocking only objects of classes yet to be
implemented works well. However when I try to mock a class method and
instance methods for objects of the same class I am not sure how the
preferred way to do this looks like.
I have code that e.g. looks like this:
new_book = Book.new
content = new_book.read_page(5)
I now want to mock out everything that has to do with the class "Book". In
this example this would mean "Book.new" and "new_book.read_page"
Would I first mock the object using
book_object = double("Book")
allow(book_object).to receive(:read_page).and_return(...)
and then mock the class by
book = class_double("Book")
allow(book).to receive(:new).and_return(book_object)
Is this the way to go?
