Typeorm unit tests

[irakli anta]

I'm trying to write test. I'am using supertest and jest. This is my user create method.

export const createUser = async (req: Request, res: Response) => {  try {    const { firstname, lastname, email, password } = req.body;    let fileName;    if (req.files) {      const avatar = req.files!.avatar;      fileName = uploadOne(avatar, 250, 250);    } else {      fileName = "avatar.jpg";    }    const user = new User();    user.firstname = firstname;    user.lastname = lastname;    user.email = email;    user.password = password;    user.avatar = fileName;    await user.save();    return res.json({      success: true,      user,    });  } catch (e) {    if (e instanceof Error) {      return res.status(400).json({        message: e.message,      });    }  } };

and i want to test it. this is my test.

import request from "supertest"; import app from "../src/app"; describe("test create route", () => {  test("Should have success and user", async () => {    const res = await request(app).post("/api/v1/users").send({      firstname: "John",      lastname: "Gotti",      email: "[e-mail]",      password: "123@Saiuo09!",    });    expect(res.body).toHaveProperty("success");    expect(res.body).toHaveProperty("user");  }); });

But when i run test am getting this error. message": "DataSource is not set for this entity. I searched this error but didn't get anything useful. can someone please help me with this...

Welcome to the Ranch.

I'm not familiar a lot with JavaScript, Node.js etc.. And what I found isn't exact answer to your question, however, it may give an idea what needs to be done: https://stackoverflow.com/questions/35005001/loopback-testing-with-supertest-mocha-and-models

In order to use a database you need some kind of datasource.  Is it a database, a file? Show your code where you set the datasource or some kind of connection string.
