kill/shutdown 1 simulator

[oliverhu]

Hey Johannes,

Suppose we have 5 simulators running, are you aware of any command to kill/shutdown only a single of them .. If you kill the process/simctl shutdown, all simulators will be killed :\

If you know the UDID, try this:

SimCtl.device(udid: "105D3EE7-BC54-4973-9C52-0719B95B2552").kill!

This assumes that you actually launched it via the simctl gem (looking for CurrentDeviceUDID in the process list).

Tried, not working. All sims are killed :(

#!/usr/bin/env ruby

require 'simctl'

runtime = SimCtl.runtime(name: 'iOS 9.2')
devicetype = SimCtl.devicetype(name: 'iPhone 5')

d1 = SimCtl.create_device 'Device 1', devicetype, runtime
d2 = SimCtl.create_device 'Device 2', devicetype, runtime

d1.wait! { |d| d.state == :shutdown }
d2.wait! { |d| d.state == :shutdown }

d1.launch!
d2.launch!

puts "d1: #{d1.udid}"
puts "d2: #{d2.udid}"

puts "Both devices launched..."
puts `ps auxww | grep Simulator.app`

d1.kill!

puts "One device killed..."

sleep 1

puts `ps auxww | grep Simulator.app`

Output:

d1: E75A557C-8080-4CC8-B468-1510028CE363
d2: 6E5A53D3-4856-497C-9BB0-D0DCFF121807
Both devices launched...

This works. But .. if I killed one in the middle of running tests in multiple simulators. All of them are killed.

Basically what i want to achieve is have a retry logic. If a simulator failed to start a test bundle, we can reset that and start testing on that simulator again :D

Try passing to xctool when you do run-tests: -noResetSimulatorOnFailure

If that doesn't help, I'm out of ideas...
