Learn how to test your Crystal exercises on Exercism
When you are in the directory for an exercise, you should see two subdirectories:
src
contains your solution to the exercisespec
contains the tests to run for the exerciseIf you're in the right directory (i.e. the one containing src
and spec
), you can run the tests for that exercise by running crystal spec
:
$ pwd
/Users/johndoe/Code/exercism/crystal/hello-world
$ ls
GETTING_STARTED.md README.md spec src
$ crystal spec
This will run all of the test files in the spec
directory.
In each test file, all but the first test have been skipped.
Once you get a test passing, you can unskip the next one by changing pending
to it
.
Before submitting, it's recommended that you run crystal tool format
on your solution.
You can format everything in your current directory with:
$ crystal tool format ./
Or you can selectively format files with:
$ crystal tool format ./<path>/<to>/<file>
Be sure to submit the source file in the src
directory when submitting your solution:
$ exercism submit src/<exercise>.cr
