检查 MockedProvider 的 options 中的 mocks 是否正确设置，并确保 mock 数据与查询的数据类型和结构匹配。例如：

// mocks.js
const mocks = [
  {
    request: {
      query: GET_USER_QUERY,
      variables: { userId: 1 },
    },
    result: {
      data: {
        user: {
          id: 1,
          name: "John Smith",
          email: "john.smith@example.com",
        },
      },
    },
  },
];

// MyComponent.test.js
import { MockedProvider } from "@apollo/client/testing";
import MyComponent from "./MyComponent";
import { GET_USER_QUERY } from "./queries/mutations";
import { render, waitFor } from "@testing-library/react";

it("renders user data after loading", async () => {
  const mocks = [
    {
      request: {
        query: GET_USER_QUERY,
        variables: { userId: 1 },
      },
      result: {
        data: {
          user: {
            id: 1,
            name: "John Smith",
            email: "john.smith@example.com",
          },
        },
      },
    },
  ];

  const { getByText } = render(
    
      
    
  );

  await waitFor(() => expect(getByText("John Smith")).toBeInTheDocument());
});
