Open too many simulators (I wrote only 2 destinations)

[amesandy-zz]

Using this
pxctest
run-tests
--destination 'name=iPad Air,os=iOS 10.2'
--destination 'name=iPad Air,os=iOS 10.2'
--testrun "/Users/username/Library/Developer/Xcode/DerivedData/MyApp-erqmuczdcogowjdmkomhdxdfgnfa/Build/Intermediates/CodeCoverage/Products/MyApp_iphonesimulator10.2-x86_64.xctestrun"

I see more than 5 simulator opening and it keeps opening more, I have to kill command line to stop it.

It runs all test targets in parallel. You can limit that via --only targetname.
