Full report

From about 7 credits for a typical project

  • AI-written edge cases for the riskiest files
  • Every untested file ranked
  • Up to 20,000 files

Who it is for

QA engineers and developers

  • Decide which tests to write first
  • Show test risk in a sprint review
  • Start testing a project that has none

Why use this instead of Coverage tools (Istanbul, Codecov)?

  • Works before you have any test setup
  • Ranks untested files by risk, not just percentage
  • Suggests the concrete edge cases to write first

How it works

  1. Match source files to test files
  2. Score risk by size and exports
  3. Suggest edge cases for the top modules

What we read

File names and the first lines of the riskiest untested files.

Limits: Coverage is matched by file name, not measured. Suggested cases are not executed.
