Exercism Java test runner

A test runner automatically verifies if a submission passes all the tests.

This repository contains the Java test runner, which implements the [test runner interface][test-runner-interface].

Run the test runner

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

Open a terminal in the project's root
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.

Run the test runner on an exercise using Docker

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:

Open a terminal in the project's root
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.

Run the tests

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

Open a terminal in the project's root
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>/expected_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>/expected_results.json file.
