`tns test <platform>` does not work in case the application is not installed on the device.

[rosen-vladimirov]

In case application is not installed on the device, instead of running the tests, the original app is stared.

Steps to reproduce

• Create new app - tns create myApp
• Navigate to the app - cd myApp
• Initialize test structure - tns test init
• Run the tests (make sure you do not have org.nativescript.myApp installed on the device): tns test <platform>

Workaround

Install the app first:

• tns run <plartform> --justlaunch

Also we must prepare the project first and start Karma launcher after that - in case the project is TypeScript, we will not have the .js files and the tests will not run. Preparing the project will generate the .js files :)

Scenarios that must be tested:

• Application is not installed on device:
  • tns test <platform> - should prepare the project, deploy it on device and start the tests
  • tns test <platform> --watch should prepare the project, deploy it on device and start the tests. When change is applied, test must be restarted. NOTE: Test must be restarted no matter if .xml, .css or .js is changed.
• Application is installed on device:
  • tns test <platform> - prepare the project and run the tests
  • tns test <platform> --watch should prepare the project, deploy it on device and start the tests. When change is applied, test must be restarted. NOTE: Test must be restarted no matter if .xml, .css or .js is changed.
• TypeScript application
  • tns test <platform> - make sure that you do not have .js files in your app folder before testing - this command should transpile the files, prepares the project and runs the tests
  • tns test <platform> --watch - make sure changing of .ts files does not lead to infinite loop
• Debug:
  • tns test <platform> --debug-brk should break and allow you to debug the application
  • tns test <platform> --debug-brk --watch should fail - these two flags cannot be used simultaneously.
• Additional tests
  • tns test <platform> and after that tns run <platform> - first call should run the tests, the second one should run the real application
  • tns test <platform> and after that tns livesync <platform> - first call should run the tests, the second one should deploy changed files on device and start the REAL application.
