Does a mocked method's code actually run

Question

Hi I'm using Mocha for a Rails project. I'm new to TDD so please forgive me if this is a stupid question.

If I have this

@client.expects(:create_config).once.returns(true)

then am I right in assuming that the code in create_config() won't be run and instead true will just be returned?

Never used mocha, but this is indeed the case for all mocking frameworks i've worked with
