## Legacy integration tests
`./integration` contains Docker's legacy integration tests.
It is DEPRECATED and will eventually be removed.
### If you are a *CONTRIBUTOR* and want to add a test:
* Consider mocking out side effects and contributing a *unit test* in the subsystem
you're modifying. For example, the remote API has unit tests in `./api/server/server_unit_tests.go`.
The events subsystem has unit tests in `./events/events_test.go`. And so on.
* For end-to-end integration tests, please contribute to `./integration-cli`.
### If you are a *MAINTAINER*
Please don't allow patches adding new tests to `./integration`.
### If you are *LOOKING FOR A WAY TO HELP*
Please consider porting tests away from `./integration` and into either unit tests or CLI tests.
Any help will be greatly appreciated!
