General info

XCTest is the default testing framework for unit tests, performance tests, and some level of UI tests for iOS apps.

XCTest framework is a testing framework that enables developers write basic unit tests, performance tests, and some level of UI tests for iOS apps.

QUnit is a JS Unit testing framework.

QUnit is especially useful for regression testing of jQuery, jQuery UI and jQuery Mobile projects
xUnit
