// Tests for decrypting DRM-infested content using containerized helper applications
//
// This is split out into a different file from the tests in content_protection.rs in order to be
// able to disable the tests on ARM64 MacOS CI runners on Github. These runners don't currently
// enable nested virtualization, and thus Podman/Docker don't work.
//
// To run tests while enabling printing to stdout/stderr
//
//    cargo test --test content_protection_containerized -- --show-output
