I'm trying to run tests in my NestJS application using NodeJS native test runner, but I'm having some trouble.
1 - I can't run multiple test files with this script "test": "node -r tsconfig-paths/register -r ts-node/register --test ./test". It only works if I put the full path to a specific test file in the script, like "test": "node -r tsconfig-paths/register -r ts-node/register --test ./test/auth.test.ts", but this way I would have to create a script for each test file.
2 - I don't know why, but the "assert" object is undefined during the test. I saw people importing it as import assert from "node:assert" or import assert from "node:assert/strict", but if I try to import like this I get this error TypeError [Error]: Cannot read properties of undefined (reading 'strictEqual'). I had to import it as import { strict as assert } from "node:assert" and so it worked, but the other imports are way better.
This is my test code in case someone wants to see, but I still need to finish it.
import * as request from 'supertest';
import { INestApplication } from '@nestjs/common';
import { Test } from '@nestjs/testing';
import { AppModule } from '@src/app.module';
import { describe, before, after, it } from 'node:test';
import { strict as assert } from 'node:assert';
import { SignupDTO } from '@src/entities/user/user.type';
describe('Auth', () => {
let app: INestApplication;
before(async () => {
const moduleRef = await Test.createTestingModule({
imports: [AppModule],
}).compile();
app = moduleRef.createNestApplication();
await app.init();
});
it('/POST signup', async () => {
const body = new SignupDTO();
body.name = 'Miguel O Hara';
body.email = 'spiderman2099@testmail.com';
body.password = 'spiderman2099';
body.password_confirmation = 'spiderman2099';
await request(app.getHttpServer())
.post('/auth/signup')
.send(body)
.then((response)=>{
assert.strictEqual(response.statusCode, 200);
});
});
after(async () => {
await app.close();
});
});
If someone is working with node test runner and NestJS, I would really enjoy some tips. I just started using node native test runner instead of Jest, so I'm pretty new in this.
