Feature: Argument matchers
Bogus supports some argument matchers for use, when you don't really care about exact equality of arguments passed in or spied on.
Background:
Given a file named "catalog.rb" with:
"""ruby
class Catalog
def self.books_by_author_and_title(author, title)
end
end
"""
Scenario: Stubbing methods with any arguments
Then the following test should pass:
"""ruby
require_relative 'catalog'
stub(Catalog).books_by_author_and_title(any_args) { :some_book }
expect(Catalog.books_by_author_and_title("Arthur Conan Doyle", "Sherlock Holmes")).to eq(:some_book)
"""
Scenario: Stubbing methods with some wildcard arguments
Then the following test should pass:
"""ruby
require_relative 'catalog'
stub(Catalog).books_by_author_and_title(any_args) { :some_book }
stub(Catalog).books_by_author_and_title("Mark Twain", anything) { :twains_book }
expect(Catalog.books_by_author_and_title("Mark Twain", "Tom Sawyer")).to eq(:twains_book)
expect(Catalog.books_by_author_and_title("Mark Twain", "Huckleberry Finn")).to eq(:twains_book)
expect(Catalog.books_by_author_and_title("Arthur Conan Doyle", "Sherlock Holmes")).to eq(:some_book)
"""
Scenario: Stubbing methods with proc arguments matcher
Then the following test should pass:
"""ruby
require_relative 'catalog'
stub(Catalog).books_by_author_and_title(any_args) { :some_book }
stub(Catalog).books_by_author_and_title(with{|author| author =~ /Twain/ }) { :twains_book }
expect(Catalog.books_by_author_and_title("Mark Twain", "Tom Sawyer")).to eq(:twains_book)
expect(Catalog.books_by_author_and_title("M. Twain", "Huckleberry Finn")).to eq(:twains_book)
expect(Catalog.books_by_author_and_title("Arthur Conan Doyle", "Sherlock Holmes")).to eq(:some_book)
"""
Scenario: Stubbing methods with proc argument matcher
Then the following test should pass:
"""ruby
require_relative 'catalog'
stub(Catalog).books_by_author_and_title(any_args) { :some_book }
stub(Catalog).books_by_author_and_title(matches{|author| author =~ /Twain/ }, "Tom Sawyer") { :twains_book }

"""
Scenario: Stubbing methods with argument type matcher
Then the following test should pass:

stub(Catalog).books_by_author_and_title(any(String), any(String)) { :twains_book }
