What is real meaning of suiteName in UserDefaults initializer?

I attempting to grasp some kind of unit tests, so we create mock user defaults.

class MockUserDefaults: UserDefaults {
var gameStyleChanged = 0
override func set(_ value: Int, forKey defaultName: String) {
if defaultName == "something" {
  someStyleChanged += 1
}
}
}

right after in setup() i create 

mockUserDefaults = MockUserDefaults(suiteName: "testing")!

So i confused i can't understand full meaning of suiteName i've read official documentation but it is not clear enough, please help

suiteName:is kind of an identifier which helps you create preferences(UserDefaults) store. By using a particular suiteName, you are creating a preferences store, that is not bounded to a particular application (whereas standard UserDefaults are different for every application). Because of this reason, you can create a store, that can be shared between different app/extensions.
