Issue: Not able to run unit tests for nativescript-angular

[lambourn]

I am not able to run the unit tests inside the tests folder. Here is what I did:

Steps

1. Cloned the nativescript-angular repo
2. cd to tests folder
3. tns platform add android
4. tns test android (ran it on an emulator btw.)

Result

• Test runner application starts on emulator
• 95 tests get collected
• 10 test cases get executed, then the runner crashes

Error points to zone-nativescript.js. Here is the relevant stack trace from console:

[lambourn]

after some research it turns out that the error is caused by socket.io.js's call to JSONPPolling.doPoll

Something similar was already reported here

Out of interest: do the unit tests in nativescript-angular suppose to work out-of-the-box? Do they work for the NS team?
