Testing on the Roc track

To download an exercise, for example hello-world, open a terminal and run:

exercism download --track roc --exercise hello-world

Then go to the exercise directory and edit the code to solve the exercise. For example:

cd {your Exercism folder}/roc/hello-world
edit HelloWorld.roc

Each exercise comes with a test suite. You can run the tests using the roc test command, for example:

roc test hello-world-test.roc

If you've solved the exercise, you should see 0 failed tests, for example:

0 failed and 1 passed in 583 ms.

However, if your code has any errors, they will look like this:

── EXPECT FAILED in hello-world-test.roc ───────────────────────────────────────

This expectation failed:

6│  expect hello == "Hello, World!"
    ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^


1 failed and 0 passed in 1264 ms.

This should help you fix your code. Once your code works, you can submit it using the exercism submit command (see HELP.md in the exercise directory for more details).
