# 测试
测试基于 [Jest](https://jestjs.io/) 测试框架。为了方便的编写测试,提供了 `mockDatabase()``mockServer()` 用于数据库和服务端应用的测试。
## `mockDatabase()`
默认提供一种完全隔离的 db 测试环境
```ts
import { mockDatabase } from '@nocobase/test';
describe('my db suite', () => {
let db;
beforeEach(async () => {
db = mockDatabase();
db.collection({
name: 'posts',
fields: [
{
type: 'string',
name: 'title',
}
]
});
await db.sync();
});
afterEach(async () => {
await db.close();
});
test('my case', async () => {
const repository = db.getRepository('posts');
const post = await repository.create({
values: {
title: 'hello'
}
});
expect(post.get('title')).toEqual('hello');
});
});
```
## `mockServer()`
提供模拟的服务端应用实例,对应的 app.db 为 `mockDatabase()` 实例,同时还提供了便捷的 `app.agent()` 用于测试 HTTP API针对 NocoBase 的 Resource Action 还封装了 `app.agent().resource()` 用于测试资源的 Action。
```ts
import { mockServer } from '@nocobase/test';
class MyPlugin extends Plugin {
}
describe('my suite', () => {
let app;
let agent;
beforeEach(async () => {
app = mockServer();
agent = app.agent();
// 添加待注册的插件
app.plugin(MyPlugin, { name: 'my-plugin' });
// 加载配置
app.load();
// 清空数据库并安装
app.install({ clean: true });
});
afterEach(async () => {
await app.destroy();
});
test('my case', async () => {
await agent.resource('posts').create({
values: {
title: 'hello'
}
});
await agent.get('/users:check').set({ Authorization: 'Bearer abc' });
});
});
```
## 示例
我们以之前在 [资源与操作](development/guide/resources-actions) 章节的功能为例,来写一个插件的测试:
```ts
import { mockServer } from '@nocobase/test';
import Plugin from '../../src/server';
describe('shop actions', () => {
let app;
let agent;
let db;
beforeEach(async () => {
app = mockServer();
app.plugin(Plugin);
agent = app.agent();
db = app.db;
await app.load();
await db.sync();
});
afterEach(async () => {
await app.destroy();
});
test('product order case', async () => {
const { body: product } = await agent.resource('products').create({
values: {
title: 'iPhone 14 Pro',
price: 7999,
enabled: true,
inventory: 1
}
});
expect(product.data.price).toEqual(7999);
const { body: order } = await agent.resource('orders').create({
values: {
productId: product.data.id
}
});
expect(order.data.totalPrice).toEqual(7999);
expect(order.data.status).toEqual(0);
const { body: deliveredOrder } = await agent.resource('orders').deliver({
filterByTk: order.data.id,
values: {
provider: 'SF',
trackingNumber: '123456789'
}
});
expect(deliveredOrder.data.status).toBe(2);
expect(deliveredOrder.data.delivery.trackingNumber).toBe('123456789');
});
});
```
编写完成后,在命令行中允许测试命令:
```bash
yarn test packages/samples/shop-actions
```
该测试将验证:
1. 商品可以创建成功;
2. 订单可以创建成功;
3. 订单可以发货成功;
当然这只是个最基本的例子,从业务上来说并不完善,但作为示例已经可以说明整个测试的流程。
## 小结
本章涉及的示例代码整合在对应的包 [packages/samples/shop-actions](https://github.com/nocobase/nocobase/tree/main/packages/samples/shop-actions) 中,可以直接在本地运行,查看效果。
