I have an automation framework running in MAC which open a simulator trough Appium. I want to open multiple iOS simulator in order to run different test cases at the same time, what are the options that I have?

Since Xcode 9 and Appium 1.7, this is now possible. The key is the wdaLocalPort capability. Each simulator needs its own port.

Here's an example, I use ruby, but it will be similar in other languages as well:

require 'appium_lib'

opts = {
  caps: {
    automationName: 'XCUITest',
    platformName: 'iOS',
    deviceName: 'iPhone 7',
    wdaLocalPort: 8001,
    app: 'Example.app',
  },
}

10.times do
  driver = Appium::Driver.new(opts, true)
  driver.start_driver.manage.timeouts.implicit_wait = 10
  driver.find_element(:name, 'Button').click
  driver.driver_quit
end

I couldn't be bothered to implement the concurrency, so you'll have to manually execute the next script at the same time as the first one.

require 'appium_lib'

opts = {
  caps: {
    automationName: 'XCUITest',
    platformName: 'iOS',
    deviceName: 'iPhone 8',
    wdaLocalPort: 8002,
    app: 'Example.app',
  },
}

10.times do
  driver = Appium::Driver.new(opts, true)
  driver.start_driver.manage.timeouts.implicit_wait = 10
  driver.find_element(:name, 'Button').click
  driver.driver_quit
end

I haven't played with this too much, but when I used two simulators, I ran twice the amount of tests in the same time. Would be interesting to see how well it scales.

EDIT: Turns out that I could be bothered to implement the concurrency:

require 'appium_lib'

device_names = [
  'iPhone 6',
  'iPhone 6s',
  'iPhone 7',
  'iPhone 8',
]

def test(device_name, port)
  opts = {
    caps: {
      automationName: 'XCUITest',
      platformName: 'iOS',
      deviceName: device_name,
      wdaLocalPort: port,
      app: 'Example.app',
    },
  }
  driver = Appium::Driver.new(opts, true)
  driver.start_driver.manage.timeouts.implicit_wait = 10
  driver.find_element(:name, 'Button').click
  driver.driver_quit
end

device_names.each_with_index do |device_name, i|
  fork {
    10.times do
      test(device_name, 8000+i)
    end
  }
end

Process.waitall

The above will launch as many simulators as you specify in the device_names array and run 10 tests on each of them. I also wrote a more complicated script for benchmarking. Between 3 and 4 simulators I had less than a 10% increase in performance, so running more than 4 doesn't seem worth while, but I suppose that depends on your system.

As you launch more and more simulators, you will likely run out of system resources. Here's how you deal with that: https://stackoverflow.com/a/46819409/310121

The technical limitation of appium of 1 device in 1 mac can be solved by using Sauce Lab's mobile cloud which presents running multiple simulators/devices at the same time. you need to enroll/signup to use them

Check this library https://github.com/facebook/FBSimulatorControl, it will give you the ability to run multiple IOS simulators in the same host.
