Containerizing Tests with Docker
Containers != mini-VMs https://twitter.com/rhein_wein/status/662995114235678720
Motivation
#1 If tests (except unit tests) are hard to run
locally, developers will not run them. ¯\_(ツ)_/¯
#2 Sometimes, it’s really hard to configure a test environment.
“Docker delivers a predictable, reproducible testing environment." ❤ (Laura Frank,
Codeship)
