See the should_not gem for a way to enforce this in RSpec and the should_clean gem for a way to clean up existing RSpec examples that begin with 'should.' before :each do # expect の場合、メソッドが実際に呼ばれないとエラーになる expect(Foo).to receive(:foo).and_raise(FooError) expect_any_instance_of(Bar).to receive(:bar).and_raise("message") # allow の場合、メソッドが実際に呼ば Given a class TheClass, TheClass.any_instance returns a Recorder, which records stubs and message expectations for later playback on instances of TheClass. If tests are too hard to write, you won't write them. but that's not available in the version of rspec I am using. Use any_instance.stub on a class to tell any instance of that class to. and_return ( " Wibble " ) expect_any_instance_of ( Widget ) .

Nearly all strategies for testing automation depend on some fundamentalconcepts. If no instance. configuration ⇒ Object Mocks specific configuration, as distinct from RSpec.configuration which is core RSpec configuration. Here is the code from the section on RSpec Doubles − おそらく、 expect_any_instance_of はどのインスタンスも対象にとるが、対象のインスタンスは1つに限るということなのだと思います。 どうするか そのため、stub を使って Hoge .new でつくられる インスタンス を同じにして、その インスタンス の Hoge #say が合計2回呼ばれるということを … stub (do_something: 23) Cependant, le dernier joyau de la version de rspec (1.1.11, octobre 2008) n'ont pas ce patch en elle. これは、継承の親クラスに対してany_instance指定し、実際には子クラスのメソッドが呼び出された場合に発生します。 仕様のようです。 https 仕様のようです。 # File 'lib/rspec/mocks.rb', line 69 def self. configuration ⇒ Object Mocks specific configuration, as distinct from RSpec.configuration which is core RSpec configuration. Is there another way to access and stub @bar? RSpec の should/stub から expect/allow の早見表. I hope to get around to addressing it at some point, but it's not simple to add this in a way that doesn't break existing spec suites that use any_instance with a block implementation, because we would start yielding an additional argument (e.g. I've added support for and_raise got a passing build on 1.9.2-p136 and 1.8.7-p330.. 1.8.6-p399 fails on line 103 of any_instance.rb because of the changes to blocks passed to block syntax. RSpec does not explicitly require the use of test spies to make message expectations. to receive ( :name ) . I run rspec spec/example_spec.rb.
