Emulator:

Karma server

Debug console

To Reproduce
tns test android

Expected behavior
run tests and see output on chrome and emulator.

Please help me on this

Reproduce the failure with tns test android using the listed CLI, runtime, and Angular versions. Start with the Karma configuration and src/tests/**/*.ts entries, then inspect the Android NativeScript Unit Test Runner launch around the reported ReferenceError. Done means the Android test command starts and executes the suite without the window error.
