NativeScript Unit Test Runner

The `nativescript-unit-test-runner` package provides the core infrastructure for executing unit tests within NativeScript applications. It is primarily consumed by the NativeScript CLI (`tns test`) and integrates with standard JavaScript testing frameworks like Karma, Jasmine, and Mocha. The current stable version is `4.0.1`, which includes support for NativeScript 9 and improved ES Module syntax handling. This package acts as the bridge between your test code, the NativeScript runtime, and the underlying test runner environment, facilitating the execution of tests directly on emulators, simulators, or physical devices. It addresses the complexities of running tests in a device-native context, a key differentiator from web-based test runners, and has an active release cadence with major version updates supporting new NativeScript versions.
