This video explains how to get started with unit testing in Swift using XCTest. It demonstrates how to write unit tests for different cases, including checking for errors.
00:00:00 In this video, "Getting Started With Unit Testing | XCTest | Swift", XCTest instructor Kyle Logg begins by explaining the importance of unit testing. He then demonstrates how to create a simple, realistic project and write unit tests for it using XCTest.
00:05:00 This video describes how to get started with unit testing using XCTest for Swift. The author shows how to refactor code to make it more testable and discusses how to add a validation service to a test class.
00:10:00 The video tutorial shows how to set up unit testing for Swift using XCTest. The first test case checks if a username is valid and the second test case checks if a username is valid with a different email address.
00:15:00 This video explains how to use unit testing in Swift by testing functions that may throw errors. XCTest assertions are used to determine whether the function throws an expected error.
00:20:00 The video demonstrates how to unit test Swift code using XCTest. The examples show how to test for errors in different ways, and how to check that the expected error and the error that is actually received are the same.
00:25:00 The video discusses how to write unit tests, and shows how to add a test to check the error description against the actual error that is received.
00:30:00 This video teaches how to start testing your Swift code using XCTest. The author provides a project and a link to the project files. The author encourages viewers to add more tests to their code.
