Inheriting Validation decorators

Description

From the docs:

If a property is redefined in the descendant class decorators will be applied on it both from that and the base class.

I’m not sure it works as it should.

Reproduction

import { MinLength, IsUppercase } from "class-validator";
import { validate } from "class-validator";

class BaseClass {
    @MinLength(10)
    someProperty: string;
}

class ChildClass extends BaseClass {
    @IsUppercase()
    someProperty: string;
}

const someObj = new ChildClass();
someObj.someProperty = 'HELLO';

validate(someObj).then(result => {
    console.log(result);
});

// the output is empty array []

From what I’m reading in docs, I thought @MinLength(10) is used alongside @IsUppercase(), but I don’t see it. Moreover, I’m not sure what empty array means.

Environment

• nodejs: v12.17.0
• typescript: 3.9.5

Any update on this? I got hit by it again today. It’s quite confusing at the moment as some decorators are inherited (e.g. @IsOptional) and others aren’t.
