Channel testing

Getting started

Testing framework uses the standard unittest python package. So you can write your tests as always in a tests package or a module visible from your project. To use pypeman specifics helpers, your test case classes must inherit from test.PypeTestCase.

To launch tests, just execute :

pypeman test

Specific helpers

PypeTestCase.get_channel(channel_name)

To get a channel in test mode from your project file by name.

Channel_instance.get_node(node_name)

To get a specific node by name.

Node_instance.mock(input=None, output=None)

Allows to mock node inputs or the output msg. If you mock output, the original process() is completely bypassed. You can also use a function that takes a msg argument as input or output mock to use or modify a message.

Node_instance.last_input()

Returns last input message of a node.

Node_instance.processed

Keeps a processed message count. Reset between each test.
