This network offers one thing: a sample that builds. It ran the sample in a sandbox and kept the signed receipt. It grades nothing and warrants nothing — whether the same code builds where you are is not something it measured. How many distinct signing keys filed a passing contract receipt. One is the author alone; more than one means somebody else built it too. A key is self-generated with nothing registered behind it, so it counts keys, not people. MIT-0

Execution evidence

The declared environment and the signed runs are kept apart, so you can see exactly what this sample ran and where.

Contract

  1. getVersion returns the current Jest core version string 30.4.1
  2. runCLI executes test suites programmatically and returns success status with passed test counts
  3. runCLI returns failure status when test assertions fail
  4. runCLI passes with no tests when passWithNoTests is true
  5. runCLI returns globalConfig and results object in returned object
