The Docker image to automatically run tests on Wren solutions submitted to Exercism.

You'll need to install Wren Console and Wren Package.

Then install the Wren packages we depend on and inject our custom testie wrapper into wren_modules:

wrenc package.wren install
./bin/post-install.sh

You may need a few missing tools:

brew install jq
# for sponge
brew install moreutils

To run the tests of an arbitrary exercise, do the following:

1. Open a terminal in the project's root
2. Run ./bin/run.sh <exercise-slug> <solution-dir> <output-dir>

Once the test runner has finished, its results will be written to <output-dir>/results.json.

This script is provided for testing purposes, as it mimics how test runners run in Exercism's production environment.

To run the tests of an arbitrary exercise using the Docker image, do the following:

1. Open a terminal in the project's root
2. Run ./bin/run-in-docker.sh <exercise-slug> <solution-dir> <output-dir>

Once the test runner has finished, its results will be written to <output-dir>/results.json.

To run the tests to verify the behavior of the test runner, do the following:

1. Open a terminal in the project's root
2. Run ./bin/run-tests.sh

These are golden tests that compare the results.json generated by running the current state of the code against the "known good" tests/<test-name>/results.json. All files created during the test run itself are discarded.

When you've made modifications to the code that will result in a new "golden" state, you'll need to generate and commit a new tests/<test-name>/results.json file.
