Fix the following issues in unit test runner: * Tests cannot start when application is not installed on device * Karma does not start when there are no .js files in app dir (initial state of TypeScript projects). * `tns test <platform> --watch` is not working for TypeScript projects * `tns test <platform> --debug-brk` does not debug. Change the way unit-tests are started. The current code was: 1) Start karma server 2) When start method of `karma-nativescript-launcher` is called, it spawns new CLI process (calls `tns dev-test` command with some arguments). 3) The new CLI process writes down some files in `node_modules/nativescript-unit-test-runner` 4) The new CLI process prepares the project. 5) The new CLI process changes the entry point of the application to point to nativescript-unit-test-runner's main-page. 6) The new CLI process calls livesync-base which should restart the application. 7) In case `--watch` option is used, karma launcher will listen for `file_list_modified` event and spawn new CLI process to run the tests. Problems were in all the steps. New way: 1) When `tns test <platform>` is called, first step is to prepare the project. 2) Initialize devices service, so we are sure all devices are detected. 3) Prepare livesync data - here we set canExecuteFastSync to false, so any change will restart the application and tests will be started again. 4) Fork new process, which should start karma server. 5) When `karma-nativescript-launcher`'s start method is called in the forked process, it will send required information to current CLI process. 6) CLI process receives the data and writes the required files in `node_modules/nativescript-unit-test-runner`. 7) CLI process calls livesync. In case --debug-brk is specified, debugService is called instead. 8) karma-nativescript-launcher no longer listens for `file-list-modified` event. CLI is alreday doing this (livesync logic). 9) Entry point of application is change by `nativescript-unit-test-runner` via after-prepare hook. The new behavior depends on the livesync - when app is not installed on the device, it will be installed. In case `--watch` is used, livesync will detect changes, prepare the project and restart the app - this will start the tests again. With this change `tns dev-test` command will stop working. As I consider it not-usable, I've deceided to skip its fixing for later.
…unner2 Fix unit test runner
Fix LiveSync of platform specific / configuration specific files. Currently mappedFilePath does not respect the platform/configuration name. Add base class that can parse the files and return correct on device filename. Add unit tests for the provider.
