Morris is a simple Python library for creating notification mechanism similar to Qt signals or C# events. Application developers can create signals with a simple decorator (@signal), send signals by calling the decorated method or function, connect to and disconnect from signals with signal.connect() and signal.disconnect().

Morris comes with support for writing high-level unit tests using the SignalTestCase.{watchSignal,assertSignalFired,assertSignalNotFired}() methods. Appropriate ordering constraints on multiple signals can be tested using the SignalTestCase.assertSignalOrdering() method.

This package contains version of the library for Python 3
