How to mock axios requests with jest and enzyme?

Hi. I have simple Rails API and i want to test my axios requests.

How to mock post, delete and e.t.c?

My goal is:

• 1.Test response code

• 2.Test response body

• 3.Test that request sent only once

Here's my test:

 it('should add have ok response', async () => {
    mockAxios.get.mockImplementationOnce(() =>
      Promise.resolve({
        list: {
          board_id: 1,
          title: "Sample list"
        }
      })
    );

    const response = await postList(1);

    expect(response).toEqual({ board_id: 1, title: "Sample list" });
    expect(mockAxios.post).toHaveBeenCalledTimes(1);
    expect(mockAxios.get).toHaveBeenCalledWith(
      "https://localhost:8080/api/v1/lists",
      {
        params: {
          board_id: 1,
          title: "Sample list",
        }
      }
    );
  });

And postList function:

export const postList = async (board_id) => {
  try {
    const result = await FetchHelpers.post(`${API_ROOT}/lists`, {
      list: {
        board_id: board_id,
        title: "Sample list"
      }
    });
    return result;
  } catch (error) {
    console.error(error);
  }
}

But i get this error in test:

  ● CreateListButton › should add have ok response

    expect(received).toEqual(expected) // deep equality

    Expected: {"board_id": 1, "title": "Sample list"}
    Received: undefined

What's wrong here and how to fix that?
