The CodeCrafters creators program is invite-only. Interested in building CodeCrafters challenges? Write to us at firstname.lastname@example.org.
Once you’ve pre-launched your challenge, you’re ready to start building out the stage instructions and test cases.
It’s upto you whether you want to build test cases first or stage instructions first. We recommend building both in parallel, one stage at a time. This allows you to think about how a learner will progress through your challenge, and what they’ll need at each stage.
For each stage defined in your
course-definition.yml file, you’ll need a corresponding test case. These are defined in your tester repository. Here
are some examples from our other challenges:
We recommend testing your test cases against a “reference” implementation. For example, in the Git challenge we test
git-tester by running it against the official
Stage instructions are present in the
course-definition.yml file (under the
description_md key). Here are some examples from our other challenges:
Note: we’re still building the external course authoring feature, so updates to your tester program might not be visible on
app.codecrafters.io immediately. Updates to the stage
instructions should be visible immediately once they’re “applied” from the admin area. Let Paul know if you run into any issues.
