Feature: Global fake configuration In an ideal world, all the fakes would follow the tell-don't-ask principle, which would eliminate the need for stubbing, and would be instances of classes that match the fake name, which would eliminate the need for configuration of things like (`as: :class` / `as: :instance`). However, in reality we often need to add this kind of configuration to our fake definitions, and the more collaborators a fake has, the more duplication we introduce this way. To eliminate this duplication, Bogus comes with a DSL to configure the fakes in one place, and unify their use in all your tests. To globally configure your fakes, all you need to do is to place code like this: Bogus.fakes do fake(:fake_name, as: :class, class: proc{SomeClass}) do method_1 { return_value_1 } method_2 return_value_2 end end in your spec helper, or a file required from it. Background: Given a file named "foo.rb" with: """ruby class PublicLibrary def self.books_by_author(name) end end """ Given a file named "fakes.rb" with: """ruby Bogus.fakes do fake(:library, as: :class, class: proc{PublicLibrary}) do books_by_author [] end end """ Scenario: Globally configured fakes have all the properties configured Then spec file with following content should pass: """ruby require_relative "fakes" describe "The library fake" do fake(:library) it "is a class" do # because of the as: :class specified in the fake definition library.should be_an_instance_of(Class) end it "is a copy of PublicLibrary" do # because of the block passed into configuration library.name.should == "PublicLibrary" end it "returns has stubbed books_by_author" do # because of the inline-stubbed books_by_author library.books_by_author("Mark Twain").should == [] end end """ Scenario: Overwriting stubbed methods using fake macro Then spec file with following content should pass: """ruby require_relative "fakes" describe "The library fake" do fake(:library, books_by_author: ["Some Book"]) it "can be overridden in the shortcut definition" do library.books_by_author("Charles Dickens").should == ["Some Book"] end end """ Scenario: Overwriting stubbed methods using fake helper function Then spec file with following content should pass: """ruby require_relative "fakes" describe "The library fake" do it "can be overridden in the helper" do library = fake(:library, books_by_author: ["Some Book"]) library.books_by_author("Charles Dickens").should == ["Some Book"] end end """
