sql evaluator for mocking

Project description

https://travis-ci.org/abe-winter/pg13-py.svg?branch=master

install with pip install pg13

docs at http://pg13.readthedocs.org/en/latest/

pg13 is a SQL evaluator for python designed for testing. Normally when you want to test an application with database dependencies, you have three dangerous options:

  1. artisanal mocking: standard mocking frameworks make you specify the output of every DB call
  2. local db: have a running copy of the database
  3. everything but: test everything but the DB interaction

pg13 takes a different approach:

  • SQL is simulated in python
  • every test can create and populate its own lightweight database
  • tests are completely deterministic
  • parallelization is safe (because parallel tests have no chance of touching the same data)
  • performance: 200+ tests per second on my laptop

See the github readme for examples. https://github.com/abe-winter/pg13-py
