Containerizing Tests with Docker Compose
WAT?
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. ¯\_(ϑ)_/¯
#2 Sometimes it’s really hard to configure a test environment.
“Docker delivers a predictable, reproducible testing environment.” (Laura Frank, Codeship)
