Hands-On Server-Side Web Development with Swift

Adding a unit test to your project

Now you're ready to add your own unit tests to the Vapor 3 project you created in the last chapter. Previously, you added a new route called "student" and your web application allows a user to query for a student's record that was stored in the array studentRecords. You can add a unit test to AppTests.swift and check if this feature works as expected:

@testable import App // [1]import XCTestimport Vapor // [2]final class AppTests: XCTestCase {        func testNothing() throws {        // add your tests here        XCTAssert(true)    }    func testStudent() throws { // [3]            let myApp = try app(Environment.testing) // [4]                let studentRecords = [ // [5]            "Peter" : 3.42,            "Thomas" : 2.98,            "Jane" : 3.91,            "Ryan" : 4.00,            "Kyle" : 4.00        ]
