A practical introduction to unit testing of Python applications using Mock library
Fake it till you make it
A talk by Ravi Chandra:
A practical introduction to unit testing decoupled, service-oriented, Python applications using with Mock library. A three-tiered (server, client, and view) Flask web application is used as a motivating example across the talk. Mock helps to isolate functionality specific to a layer to facilitate fast, compact, unit testing while avoiding writing specific mock classes or using fixtures.
