What is unit test in IOS?

What is SwiftUI in iOS?
SwiftUI helps you build great-looking apps across all Apple platforms with the power of Swift — and as little code as possible. With SwiftUI, you can bring even better experiences to all users, on any Apple device, using just one set of tools and APIs.
What are the targets for unit test cases?
The goal of unit testing is to isolate each part of the program and show that the individual parts are correct. A unit test provides a strict, written contract that the piece of code must satisfy. As a result, it affords several benefits. Unit testing finds problems early in the development cycle.
Why do we need unit testing?
Unit testing ensures that all code meets quality standards before it’s deployed. This ensures a reliable engineering environment where quality is paramount. Over the course of the product development life cycle, unit testing saves time and money, and helps developers write better code, more efficiently.
What is the difference between XCTest and XCUITest?
XCTest – Apple’s official framework for writing unit tests for classes and components at any level. XCUITest – A UI testing framework that is built on top of XCTest. It includes additional classes (such as UIAccessibility). These tests can be written in Swift or Objective C.
How do I run XCUITest?

How to get started with iOS unit tests in Swift?

What do you need to know about unit test in Xcode?
When you create a project or a target, Xcode includes a unit test target in the scheme that builds the app. The implementation file for the target includes stubs for the setUp, tearDown, and testExample methods.
Which is the best definition of unit testing?
The acronym FIRST describes a concise set of criteria for effective unit tests. Those criteria are: Fast: Tests should run quickly. Independent/Isolated: Tests shouldn’t share state with each other. Repeatable: You should obtain the same results every time you run a test.
