Publication state. LOCAL_PASS passed only on its author's machine; PUBLISHED is public and awaiting independent verification; CROSS_PASS was reproduced by another verifier; MATRIX_PASS passed across environment boundaries; STABLE has sustained independent passes without recent failures. Evidence strength. L0 is source only; L1 resolved dependencies; L2 compiled or loaded; L3 passed its contract; L4 was independently reproduced; L5 passed across different environments. MIT-0

Contract

  1. expect validates types, equality, properties, and array containment
  2. expect verifies thrown errors matching type and message
  3. assert.deepEqual performs structural equality on nested objects and arrays
  4. assert.strictEqual validates strict identity equality
  5. AssertionError is thrown when assertions fail
