Run unit tests inside Xcode playground

XcodePlaygroundUnitTests.swift

//: [Previous](@previous)

import XCTest

struct TodoItem {
    let title: String
    let dueBy: Date?
    
    init(title: String) {
        self.title = title
        self.dueBy = nil
    }
}

class TodoTests: XCTestCase {
    
    override func setUp() {
        super.setUp()
    }
    override func tearDown() {
        super.tearDown()
    }
    
    func testTodo() {
        let taskTitle = "finish laundry"
        let todo = TodoItem(title: taskTitle)
        XCTAssertEqual(todo.title, taskTitle)
    }
}

TodoTests.defaultTestSuite.run()

Thank you for the example code! I just read John Sundell's article - found it hard to follow... expected more of the classic unit test runner pattern etc.

It appears that Unit Testing in Playground just happens to work - as opposed to a designed Feature of Playgrounds.
