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. assert a t with only Errorf satisfies assert.TestingT and does not satisfy require.TestingT
  2. assert a failed assert.NotNil returns false, records one failure, and calls FailNow zero times
  3. assert the statement after that failed assert still runs and panics with a runtime nil pointer dereference
  4. assert a failed require.NotNil records the same single failure and calls FailNow exactly once
  5. assert require abandons the body before the dereference, so nothing panics, and deferred cleanup still runs
  6. assert a FailNow that returns instead of calling runtime.Goexit turns require back into assert and the panic returns
  7. assert Equal rejects 1 against int64(1) and prints both types in the message, while EqualValues converts and passes
  8. assert ObjectsAreEqual compares slices by order and calls a nil slice unequal to an empty one
  9. assert the []byte shortcut in ObjectsAreEqual compares equal contents equal but still calls a nil slice unequal to an empty one, even though bytes.Equal calls those equal
  10. assert a named type over []byte never compares equal to a plain []byte in either direction, while still comparing equal to itself
  11. assert ElementsMatch ignores order but counts multiplicity, where Equal does neither
