Argument Matchers

Not A Mock supports the use of RSpec’s patterns for argument matching in mocks, and extends them. The most useful are listed below.

Anything Matcher

The anything pattern will match any value. For example:

object.should have_received(:message).with(1, anything, 3)

will match the following calls:

object.message(1, 2, 3)
object.message(1, 'Boo!', 3)

but not:

object.message(3, 2, 1)
object.message(1, 2, 3, 4)

In Any Order Matcher

The in_any_order pattern will match an array argument, but won’t care about order of elements in the array. For example:

object.should have_received(:message).with(in_any_order([3, 2, 1]))

will match the following calls:

object.message([3, 2, 1])
object.message([1, 2, 3])

but not:

object.message([1, 2, 3, 4])
