Description
In Exercism v3, one of the biggest changes is that we'll automatically check if a submitted solution passes all the tests.
We'll check this via a new, track-specific tool: the Test Runner. Each test runner is track-specific. When a new solution is submitted, we run the track's test runner, which outputs a JSON file that describes the test results.
The test runner must be able to run the tests suites of both Concept Exercises and Practice Exercises. Depending on the test runner implementation, this could mean having to update the Practice Exercises to the format expected by the test runner.
Each track must build a test runner according to the spec. For tracks building a test runner from scratch, we have a starting guide and a generic test runner that can be used as the base for the new test runner.
