Run only one Jest test file with NX

nx run myproject:test --testFile=libs/myproject/src/lib/guards/role.guard.spec.ts

I expect only a single .spec file to be tested. However, the error output shows additional .spec files.

$ nx run myproject:test --testFile=libs/myproject/src/lib/guards/role.guard.spec.ts

Ran all test suites matching /libs\\myproject\\src\\lib\\guards\\role.guard.spec.ts/i.

Why are extra tests being run such as libs/myproject/src/lib/auth/secure.directive.spec.ts ?

I must have mis-read the output when I posted this. It looks like the nx jest commands I posted, were actually working.
