Testing

We run our tests against a Substrate Docker image. You can choose to run the tests within a tests-dedicated Docker container or without a container.

make test-dockerized

Run tests within a docker container of its own against the Substrate docker container.

make test

Run the tests locally against the Substrate docker container. Note that it expects the Substrate docker container to be up and running to execute the whole test suite properly.
