Here's the output I get:
qatest -> dalek tests/mytest.js -b ios:safari
Running tests
Port must be greater than 0 and less than 65536
Invalid argument for param callbackPort: undefined
I have a Dalekfile.js also, in my project directory ('qatest'), with the following content:
{
"browsers": {
"ios": {
"portRange": [6100, 6120]
}
}
}
