Example of Unit Testing in Swift

[ApplebaumIan]

1. First Thing you gotta do is import the Xcode Testing Library

import XCTest

2. Next add the Object you're planning on testing in setup:

private var ex : Example!
   override func setUp() {
	// Put setup code here. This method is called before the invocation of each test method in the class.
	self.ex = Example()
    }

here I am testing the class Example.
3. Write a test

/*
	For information on Unit Testing in Swift I found this website https://www.swiftbysundell.com/basics/unit-testing/
*/
    func testExample() {
        // This is an example of a functional test case.
        // Use XCTAssert and related functions to verify your tests produce the correct results.
		XCTAssert(ex.getExampleVal() == 10, "NOT 10")
    }

To run the test you can simply click on the diamond next to the function in Xcode or long click on the run button and click the test button.
