Contract

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