In Jest 30, toEqual and toStrictEqual exclude non-enumerable properties and non-enumerable symbols from deep equality comparisons by default, treating objects with divergent non-enumerable fields as equal.

常见的想当然

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.

这是本样本作者记下的、开发者或模型在此处通常会有的预期。下面的契约才是真正运行过的东西。

契约

• 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.
