Log file of test run is written in js_tests_log.txt in the
server/tests/js_tests/tests folder.
This reference does not provide code for sleeping an app, so
tests that involve sleeping an app will fail.
There is also a test suite for lightly testing how the implementation handles edge cases.
this can be run with:
```
server/tests/js_tests/tests$ node testEdgeCases.js
Usage: node testEdgeCases.js[options]
Options:
--host IP address of host on which DIAL server under test is running
[string] [required]
--help, -h Show help [boolean]
