Mock/Stub/Spy library for Python

Project description

FlexMock is a mock/stub/spy library for Python.

It takes inspiration from a Ruby library of the same name, and as a result introduces much simpler syntax than other Python mocking libraries that are largely ported from Java. The aim of Python FlexMock is to be able to provide full support for mocking Python-specific features, and make the creation of fake objects as unobtrusive as possible.

More details, along with comparisons to other Python mocking libraries, are available here:

SUPPORTS:

  • test runner integration, i.e. automatic expectation checking on tearDown
  • advanced argument matching, including matching types and user-defined classes
  • expectations on number of times called, including at_least/at_most
  • mocks returning custom values, including different values on successive invokations
  • mocks raising custom exceptions
  • simple syntax for generating new mock objects
  • overriding new instances (on new-style objects)
  • parameter shortcuts for even terser syntax
  • proxying/spying using the and_execute expectation modifier
  • mocking a generator using and_yield
  • enforcing expectations ordering
