coverage

What I do

• Run deno task coverage to collect coverage data for the codebase
• Can also collect coverage for a specific file using deno task coverage <filename>
• Use deno task coverage:check to enforce coverage thresholds defined in .denocoveragerc
• Use deno task serve:coverage to serve an HTML coverage report in the browser

When to use me

Use this when you want to measure or verify test coverage:

• After adding new tests
• Before submitting a pull request (coverage must meet 100% thresholds)
• When debugging which areas of the code are under-tested
• To inspect coverage gaps interactively

Notes

• Coverage thresholds are defined in .denocoveragerc (100% for lines, branches, and functions)
• Every test change must be accompanied by coverage that satisfies these thresholds
• The HTML report is helpful for visualizing failing areas in complex serialization paths
