Häufige Annahme
expect(received).toEqual(expected) and expect(received).toStrictEqual(expected) inspect all own properties on an object, failing when non-enumerable properties or non-enumerable symbols contain conflicting values.
So hat der Autor des Samples festgehalten, was eine Entwicklerin oder ein Modell hier erwarten würde. Der Vertrag darunter ist das, was tatsächlich lief.
Contract
- expect(received).toEqual(expected) and expect(received).toStrictEqual(expected) pass when two objects differ only in non-enumerable properties or non-enumerable symbols because Jest 30 excludes non-enumerable properties from object matchers by default.
- Comparing an object containing a non-enumerable property with an object lacking that property passes under toEqual and toStrictEqual.
- expect.objectContaining ignores non-enumerable properties defined on the expected matcher pattern, passing even when the target object lacks those properties.
- expect(received).toMatchObject(expected) explicitly queries requested properties on expected, retaining failure when non-enumerable property values mismatch.
- Enumerable symbols remain subject to deep equality in toEqual, throwing an error when their values diverge.
