// These tests are the only ones that we put *in* the package. The rest of our tests live in Assets/Tests and run separately
// from our CI and not through upm-ci. This also means that IntegrationTests is the only thing we put on trunk through our
// verified package.
//
// Rationale:
// (1) Our APIVerificationTests have extra package requirements and thus need a custom package manifest.json. This will not
//     work with upm-ci.
// (2) The tests we have in Assets/Tests exercise the input system in isolation. Having these run on trunk in addition to our
//     CI in the input system repo adds little value while adding extra execution time to trunk QV runs. This is unlike
//     the integration tests here which add value to trunk by making sure the input system is intact all the way through
//     to the native input module.
// (3) If we added everything in Assets/Tests to the package, we would add more stuff to user projects that has no value to users.
//
// NOTE: The tests here are necessary to pass the requirement imposed by upm-ci that a package MUST have tests in it.
