使用jest测试axios拦截器

npm install jest axios --save-dev

import axios from 'axios';
import { interceptRequest, interceptResponse } from './axios.interceptor';

describe('interceptRequest', () => {
  it('should add an authorization header to the request', () => {
    const config = {
      headers: {},
    };
    const modifiedConfig = interceptRequest(config);
    expect(modifiedConfig.headers.Authorization).toBeDefined();
  });
});

describe('interceptResponse', () => {
  it('should handle successful response', () => {
    const response = {
      data: {
        success: true,
      },
    };
    const modifiedResponse = interceptResponse(response);
    expect(modifiedResponse.data.success).toBeTruthy();
  });

  it('should handle error response', () => {
    const response = {
      data: {
        success: false,
        message: 'Error occurred',
      },
    };
    const modifiedResponse = interceptResponse(response);
    expect(modifiedResponse.data.success).toBeFalsy();
    expect(modifiedResponse.data.message).toBe('Error occurred');
  });
});

npx jest axios.interceptor.test.js
