egg-pload1 v1.0.0

egg-node

$ back

Mock library for testing Egg applications, plugins and custom Egg frameworks with ease. egg-mock inherits all APIs from node_modules/mm, offering more flexibility.

Install

Usage

$ npm i egg-node --save-dev

Create testcase Launch a mock server with mm.app

$ app/middleware/error_handler

module.exports = () => {
    return async function errorHandler(ctx, next) {
        try {
            await next();
        } catch (err) {
            ctx.app.emit('error', err, ctx);
            const status = err.status || 500;
            const error = status === 500 && ctx.app.config.env === 'prod'
                ? 'Internal Server Error'
                : err.message;

            ctx.body = { error };
            if (status === 422) {
                ctx.body.detail = err.errors;
            }
            ctx.status = status;
        }
    };
};

Retrieve Agent instance through app.agent after mm.app started.

Using mm.cluster launch cluster server, you can use the same API as mm.app;

Test Application baseDir is optional that is process.cwd() by default.

$ app/middleware/jwt

const whiteList = ['/login', '/registry', '/getcaptcha','/getuser'];
const jwt = require('jsonwebtoken');
module.exports = () => {
    return async (ctx, next) => {
        if (whiteList.includes(ctx.path) || (ctx.method == 'GET' && ctx.path == '/list')) {
            await next();
        } else {
            let token = ctx.request.headers.token;
            if (!token) {
                ctx.body = {
                    code: 4,
                    mes: 'No access'
                }
                ctx.status = 401;
                return;
            }
            try {
                jwt.verify(token, ctx.app.config.keys);
                await next();
            } catch (error) {
                ctx.body = {
                    code: 5,
                    mes: 'Verification failed',
                    error
                }
            }
        }
    }
}

Test Framework

framework is optional, it's node_modules/egg by default.

$ app/service/list

'use strict';

const Service = require('egg').Service;

class ListService extends Service {
    async add(obj) {
        return await this.app.mysql.insert('list', obj);
    }
    async getlist(page,pageSize,search){
        let startIndex = (page-1) * pageSize;
        let total = await this.app.mysql.query(`select count(*) from list where name like '%${search}%'`);
        let res =await this.app.mysql.query(`select * from list where name like '%${search}%' limit ${startIndex},${pageSize}`);
        return {
            total:total[0]['count(*)'],
            data:res
        }
    }
    async edit(obj){
        return await this.app.mysql.update('list',obj);
    }
    async del(obj){
        return await this.app.mysql.delete('list',obj);
    }
}

module.exports = ListService;

Test Plugin

If eggPlugin.name is defined in package.json, it's a plugin that will be loaded to plugin list automatically.

You can also test the plugin in different framework, e.g. test aliyun-egg and framework-b in one plugin.

If it's detected as an plugin, but you don't want it to be, you can use plugin = false.

$ app/service/user

'use strict';

const Service = require('egg').Service;

class UserService extends Service {
    async getuser(name) {
        return await this.app.mysql.get('ykuser', { name });
    }
    async registry(obj) {
        return await this.app.mysql.insert('ykuser', obj);
    }
    async login(obj) {
        return await this.app.mysql.select('ykuser', {
            where: obj
        });
    }
}

module.exports = UserService;

API

mm.app(options) Create a mock application.

mm.cluster(options) Create a mock cluster server, but you can't use API in application, you should test using supertest.

$ app/router

'use strict';

/**
 * @param {Egg.Application} app - egg application
 */
module.exports = app => {
  const { router, controller, validator } = app;
  validator.addRule('phone', (rule, value) => {
    if (!/^1[3456789]\d{9}$/.test(value)) {
      return 'Mobile phone number verification failed'
    }
  })
  router.get('/', controller.home.index);
  router.post('/registry', controller.user.registry);
  router.post('/login',controller.user.login);
  router.get('/getcaptcha',controller.user.getcaptcha);
  router.get('/getuser',controller.user.getuser);
  router.post('/upload',controller.user.upload);
  router.resources('list','/list',controller.list);
};

You can disable coverage, because it's slow.
