收到笑话：序列化为同一字符串

Question

开玩笑地说，出于某种原因，你会得到类似的东西

expected: "test"
received: serializes to the same string

如果你这样做.toContainEqual

expected: "test"
received: "test"

这似乎只发生在将 mongoose 与 jest 一起使用时，但我认为问题与 uriEncoding 和解码有关

Answer 1

如果您正在测试请求的响应，请尝试

expected = decodeURI(encodeURI("test"))
result = [...] // equals "test"

expect(result).toEqual(expected)

这也可能有效，但有时会因为 JSON 字符串解析而出现问题

expected = <some object>
result = <object that serializes to the same string>
expect(result.toString()).toEqual(expect.toString())

如果您只是将文档的结果与对象或聚合的输出进行比较，请尝试

expect(result).toEqual(expected)
