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. beforeEach executes before each test case within a suite
  2. beforeEach awaits returned promises from async hook callbacks before test execution
  3. beforeEach executes multiple hooks registered within the same suite in registration order (FIFO)
  4. beforeEach in parent suites executes before beforeEach in nested child suites
  5. beforeEach populates test context properties accessible within downstream test cases
  6. beforeEach cleanup callbacks returned from hook functions execute after each test finishes
