## Running tests

In order to run the tests, issue the following command from the exercise
directory:

```bash
$ rebar3 eunit
```

### Test versioning

Each problem defines a macro `TEST_VERSION` in the test file and
verifies that the solution defines and exports a function `test_version`
returning that same value.

To make this test pass, add the following to your solution:

```erlang
-export([test_version/0]).

test_version() ->
  1.
```

The benefit of this is that reviewers can see against which test version
an iteration was written if, for example, a previously posted solution
does not pass current tests.

## Questions?

This covers the basic information on setting up the development
environment expected by the exercises.
