Mocks for Racket testing.
raco pkg install mock raco pkg install mock-rackunit # RackUnit integration
This library defines mocks, which are "fake" implementations of functions that record calls made to them.
Two separate packages are provided, the main package
mock and the RackUnit checks package
In standard uses, the
mock-rackunit dependency is needed only for test code. For a thorough introduction, see The Mock Guide. For a full API reference, see The Mock Reference.
