//! Port of the test application attribute of the upstream headless project.
//!
//! The original is an assembly attribute, read through reflection by the
//! session of a test assembly. There are no assembly attributes: the value
//! is a field of the [`FerroTestAssembly`](crate::FerroTestAssembly) that a
//! test crate hands to
//! [`HeadlessUnitTestSession::get_or_start_for_assembly`](crate::HeadlessUnitTestSession::get_or_start_for_assembly).
