Test suite
|
||||
==========
|
||||
|
||||
This test suite is implemented on top of the [Bats](https://github.com/sstephenson/bats/blob/master/README.md) test framework.
|
||||
|
||||
It is intended to verify the correct behavior of the Docker image `jwilder/nginx-proxy:bats`.
|
||||
|
||||
Running the test suite
|
||||
----------------------
|
||||
|
||||
Make sure you have Bats installed, then run:
|
||||
|
||||
docker build -t jwilder/nginx-proxy:bats .
