[Bug]: Jest coverage is reporting a line as untested

[Shereef]

Version

28.1.3

Steps to reproduce

Steps:

1. Clone https://github.com/Shereef/graphql-jest-coverage-attribute
2. run npm run test:cov

Expected behavior

Should get 100% coverage

Actual behavior

It's reporting 85.71% because of an attribute @Query(() => String)

Additional context

If you look at this file and delete the attribute parameter to @Query() you will get 100% coverage but the project will not work.

import { Resolver, Query } from '@nestjs/graphql';

@Resolver()
export class AppResolver {
  @Query(() => String)
  getHello(): string {
    return 'Hello World!';
  }
}

Environment

System:
    OS: macOS 13.0.1
    CPU: (10) arm64 Apple M1 Pro
  Binaries:
    Node: 16.14.2 - /usr/local/bin/node
    npm: 8.19.2 - ~/node_modules/.bin/npm
  npmPackages:
    jest: 28.1.3 => 28.1.3

I didn't know which package introduced this so I also filed this https://github.com/istanbuljs/istanbuljs/issues/707

Did you find a solution?

No sir, just put /* istanbul ignore next */ before the arrow function

P.S. I hand typed this comment from my phone Please spell check the code

Hey, thanks for answering, but my issue was regarding an nx/Angular project, so a case different from yours.
