预期阿雷拉,但收到雅斯特阵列
原标题:Expected Array but received array in Jest

我在雅斯特建立了单位(Aync)测试。 但是,当我从服务器得到回复时:

[
    {
        name: "My name"
    },
    {
        name: "Another name"
    }
]

并测试:

test( Response from server , () => {
    get( my-url ).end(error, response) => {
        expect(response.body).toBe(expect.any(Array))
    }
})

出现一些错误:

Comparing two different types of values. Expected Array but received array.

在我使用<代码>expect(response. person).any(Array)时进行工作。 但<代码>expect.toBe()是否有任何固定办法?

最佳回答

您应使用<代码>toEqual(nottoBe)比较物体和阵列。 仅限微量数据类型使用to Be。 如果您要检查回复数据类型的使用,>

问题回答

我认为,上述答案确实是有助益的,因此我如何在我的考验中加以执行。

describe("GET /api/books", () => {
  it("should get all books", () => {
    return request(app)
      .get("/api/books")
      .expect(200)
      .expect("Content-Type", /json/)
      .then((res) => {
        expect(res.body).toEqual(expect.any(Array));
      });
  });
});
