The log shows that WDA is still in the build process. Is it the full log?

This is an issue with finding the correct Unix Domain Socket to talk with the device. I will look into it a bit.

@mykola-mokhnach I had truncated the logs because it went into a fast loop looking for a app PID. I created a new git which is not truncated. https://gist.github.com/sadafyadegari/4e5020e752e8fcad2ad00275bf0298e2

Actually, it seems that launching Safari with the url as an argument does not work for these sims.

[sadafyadegari]

tested the xcode-10.2 beta 4 that came out on March 4th. Same results happen again. See logs:

[imurchie]

Update: In addition to the url not being correctly set, the Webkit Protocol has been compressed. I am investigating our implementation and should have some results by EOD.

[imurchie]

Update: I have a few things to iron out but tests in general are working. Once they all work for 12.2 I will move to making sure they still work for other platforms.
