Jest with globalsetup doesn't see tests

Say I have the following test:

describe('foo', () => {
    it('bar', () => {
        expect(1).toBe(2)
    })
})

in a file named foo.application.test.ts

And the following command in my package.json:

jest --testRegex '.*.application.test.ts'"

Running these tests fails, as you would expect. However, changing my command to:

jest --globalSetup ./tests/support/instantiateApplicationTests.ts --testRegex '.*.application.test.ts'"

Results in no tests being run at all ( the global setup file does exist), with the following log:

yarn run v1.22.4
$ jest --globalSetup ./tests/support/instantiateApplicationTests.ts --testRegex '.*.application.test.ts'
✨  Done in 0.81s.

How am I misusing globalsetup here?
