Current behavior

When using https://github.com/nestjs/nest/tree/master/sample/01-cats-app example, doing POST / with empty body doesn’t trigger validation/doesn’t result in 400 Bad Request error.

Expected behavior

Test fails, as HTTP request returns error 400 (as described in https://docs.nestjs.com/techniques/validation).

Minimal reproduction of the problem with instructions

I have changed create method to

@Post() //@Roles(‘admin’) async create(@Body() createCatDto: CreateCatDto) { //this.catsService.create(createCatDto); }

and added a test case

it(/POST cats, () => { return request(app.getHttpServer()) .post(‘/cats’) .expect(201); });

to https://github.com/nestjs/nest/blob/master/sample/01-cats-app/e2e/cats/cats.e2e-spec.ts

What is the motivation / use case for changing the behavior?

Because request validation is importtan and critical feature (and according to documentation it supposed to work).

Environment

Nest version: Cloned repo from https://github.com/nestjs/nest/commit/5e2727bf905cc3a4ca26267c6a385793088ff43e

Create a helper function which takes app as an argument and applies configuration (pipes etc).

Tests aren’t using ValidationPipe, see https://github.com/aeremin/nest/blob/a519f02b4482e28f6e93a355593a703a682bc927/sample/01-cats-app/e2e/cats/cats.e2e-spec.ts#L12-L21 Add:

app = module.createNestApplication();
app.useGlobalPipes(new ValidationPipe());
