Executing tests under Docker Compose

Now we're ready to execute some of the tests inside a container. We've used a Docker Compose file to describe the test environment for the Notes application, using the same architecture as in the production environment. The test scripts and configuration has been injected into the containers. The question is, how do we automate test execution?

The technique we'll use is to run a shell script, and use docker exec -it to execute commands to run the test scripts. This is somewhat automated, and with some more work it can be fully automated.

In test-compose, let's make a shell script called run.sh (on Windows, run.ps1):

docker-compose stopdocker-compose builddocker-compose up --force-recreate -ddocker ps
