Hey, I’m Diljith.

A passing test determines whether a student can progress to the next stage. We designed black-box checks to reduce false positives, looking beyond a successful response to whether the implementation satisfies the stage’s requirements.

We separated reusable test functions from stage definitions. This keeps the addition of stages and tests manageable without duplicating test logic or making widespread changes.

We chose central hosting over individual installations to simplify use for teaching assistants. That choice made concurrent usage and shared infrastructure key architectural considerations.
