devniel/example-typeorm-testing

Added a test example using nestjs-typeorm-testing. By now, it's necessary to install.

• @nestjs/typeorm
• @nestjs/common
• @nestjs/core
• rxjs

Todo:

• Replace nestjs-typeorm-testing with a module only about typeorm to avoid installing the modules mentioned above.

Test example

The example is here, you don't need even PostgreSQL installed on your machine to check if a hook on your entities is called or not.

import {
  createFakeConnection,
  FakeConnection
} from "@devniel/nestjs-typeorm-testing";
import { Category } from "../entity/Category";
import { Post } from "../entity/Post";

describe("test", () => {
  let connection: FakeConnection;

  beforeAll(async () => {
    connection = await createFakeConnection({
      name: "test",
      type: "postgres",
      entities: [Category, Post]
    });
  });

  it("should invoke the before and after hooks before creating a new category", async () => {
    let category = new Category();
    category.name = "A new category";
    const spyBeforeInsert = spyOn(category, "beforeInsert");
    const spyAfterInsert = spyOn(category, "afterInsert");
    const repository = connection.getRepository(Category);
    await repository.save(category);
    console.log(`Category has been saved. Category is '${category.name}'`);
    expect(spyBeforeInsert).toHaveBeenCalled();
    expect(spyAfterInsert).toHaveBeenCalled();
  });
});

Example how to use TypeORM with TypeScript

1. clone repository
2. run npm i
3. edit ormconfig.json and change your database configuration (you can also change a database type, but don't forget to install specific database drivers)
4. run npm start
5. enjoy!

How to use CLI?

1. install typeorm globally: npm i -g typeorm
2. run typeorm -h to show list of available commands
