Testing on the MoonScript track is exactly like testing on the Lua track.
From an exercise directory, enter:
$ busted
Pending tests
This track follows Exercism's Test-Driven Development methodology.
You are given a complete test suite, but only the first test is "active".
To enable the tests, change a test's command from pending to it.
For those of you that like to run all the tests all the time, you can use a command-line tool to change them all at once.
Here's an example using perl (which is installed just about everywhere):
$ perl -i -pe 's/^\s+\Kpending\b/it/' two_fer_spec.moon
When you are working in the online editor, the test runner will automatically run all the tests.
Using LuaRocks
Lua by itself is a very small language.
LuaRocks is the package manager for Lua modules.
You are free to use any module in your solutions, but not all of them will be available in the online test-runner.
The test-runner provides these:
