Supertest: Cannot inject the dependency at position #0 of

[gleysonabreu]

I try create a test but this error persist. Maybe any incompatibility? ( On Insomnia all works fine.)
When I use .get('/products') always returns code 404 page not found.

This is my code:

/* eslint-disable @typescript-eslint/camelcase */
import '@shared/infra/typeorm';
import request from 'supertest';
import app from '@shared/infra/http/app';

describe('Authentication', () => {
  it('should authenticate with valid credentials', async () => {
    const response = await request(app).post('/session').send({
      login: 'email',
      password: 'sss',
    });
    expect(response.status).toBe(200);
  });
});

The error happened because connection not initialized yet so create a async await connection and now works fine.

Could you please write your example? I'm facing the same issue. Thanks!

I changed my connection to async/await, like this:

const connection = async (name = 'default'): Promise<Connection> => {
  return createConnection(
    Object.assign(ormConfig, {
      name,
    }),
  );
};
export default connection;

And changed my tests to:

import createConnection from '@shared/infra/typeorm';
import { Connection, getConnection } from 'typeorm';
let connection: Connection;

describe('Tests', () => {
  beforeAll(async () => {
    connection = await createConnection();
  });

  afterAll(async () => {
    const myConnection = getConnection();
    await connection.close();
    await myConnection.close();
  });

 it('should be anything', async () => {
  //TODO
});

});

This way I can solve the connection problem with the tests.

This worked perfectly to me! Thank you @gleysonabreu !

@gleysonabreu pode mostrar o formato do seu ormConfig ? Tentei da forma que comentou porém continuo com problemas, agora retorna o seguinte erro:

@gleysonabreu pode mostrar o formato do seu ormConfig ? Tentei da forma que comentou porém continuo com problemas, agora retorna o seguinte erro:

@gdlopes Meu código do ORM eu fiz com typescript:

import { ConnectionOptions } from 'typeorm';
import dotenv from 'dotenv';

dotenv.config({
  path: process.env.NODE_ENV === 'development' ? '.env.development' : '.env',
});

const ormConfig: ConnectionOptions = {
  type: 'postgres',
  host: process.env.TYPEORM_HOST,
  port: Number(process.env.TYPEORM_PORT),
  username: process.env.TYPEORM_USERNAME,
  password: process.env.TYPEORM_PASSWORD,
  database: process.env.TYPEORM_DATABASE,
  synchronize: process.env.TYPEORM_SYNCHRONIZE === 'true',
  logging: process.env.TYPEORM_LOGGING === 'true',
  entities: [String(process.env.TYPEORM_ENTITIES)],
  migrations: [String(process.env.TYPEORM_MIGRATIONS)],

  cli: {
    migrationsDir: process.env.TYPEORM_MIGRATIONS_DIR,
  },
};

export = ormConfig;

As variáveis de ambiente são:

# TYPEORM
TYPEORM_CONNECTION=postgres
TYPEORM_HOST=localhost
TYPEORM_USERNAME=postgres
TYPEORM_PASSWORD=password
TYPEORM_PORT=5432
TYPEORM_SYNCHRONIZE=false
TYPEORM_LOGGING=false
TYPEORM_DATABASE=password
TYPEORM_ENTITIES=./src/modules/**/infra/typeorm/entities/*.ts
TYPEORM_MIGRATIONS=./src/shared/infra/typeorm/migrations/*.ts
TYPEORM_MIGRATIONS_DIR=./src/shared/infra/typeorm/migrations

Cara, muito estranho, fiz exatamente dessa forma mas o erro continua:

Porém se eu deixar assim, funciona:

import "reflect-metadata";
import { createConnection } from 'typeorm';

createConnection();

O problema é que dessa forma está dando erro nos testes de integração. Mas a aplicação em si funciona perfeitamente.

Tem ideia do que pode ser @gleysonabreu ?

@gdlopes o problema que eu estava tendo era justamente esse funcionava normal mas com os testes não funcionava e como resolvi foi transformar a conexão em async/await e coloca o método beforeAll como async await e importar a conexão em cada arquivo de teste e resolveu meu problema. Dei uma pesquisa aqui agora para vê se encontrava algo novo sobre mas não achei nada de útil relacionado ao problema.

e necessario importar o container no primeiro arquivo da sua aplicacao

ex: import "./shared/container"
