[Bug]: passWithNoTests flag ignored for empty test files

[Merovech]

Version

29.7.0

Steps to reproduce

1. Clone my repo at https://github.com/Merovech/jest-bug
2. Run npm i
3. Execute one of the below commands using npm run

Commands:

Name	Alias
test:noargs	jest --verbose
test:cmd	jest --passWithNoTests --verbose
test:config	jest --config=jest.testconfig.js
test:showconfig	jest --config=jest.testconfig.js --showConfig

Expected behavior

The passWithNoTests flag should treat an empty file as having no tests and not throw an error.

Actual behavior

All results are the same, regardless of whether I put the parameter on the command line, in a config file, or exclude it altogether.

No parameter

$ npm run test:noargs

> test:noargs
> jest --verbose

 FAIL  ./empty.test.js
  ● Test suite failed to run

    Your test suite must contain at least one test.

Additional context

I don't honestly know if this is a bug or deliberate behavior (in which this shouldn't be a bug report but rather a feature request) and I can't find out the answer. But I think it's a perfectly reasonable thing for a developer to create empty test files when adding a feature and fleshing them out later. And on a system where all test files are picked up automatically, this shouldn't fail.

The workaround is to add an empty test suite and a single test to it. But that seems clunky.

Environment

This command does not work in windows.  See https://github.com/tabrindle/envinfo/issues/238.  If anyone knows a workaround I'd be happy to update this report with it.
