# 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()` 和 `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/server/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。
