Coverage Check

Determine if a text sample has full alphabet coverage. A sample with full coverage uses every letter of the alphabet at least once. The best-known example is: > The quick brown fox jumps over the lazy dog.

Coverage Check
Step 1
Clone the starter repo
Candidate gets the full project locally — README, source, tests, runner config.
Step 2
Run the visible tests
Public test file is right there. Expectations are explicit from minute one.
Step 3
Make tests pass, push
Candidate works in their own style, pushes reviewable commits for your team.
