XCUI Testing
A test for this code:
func test_using_text_strings3() throws {
let app = XCUIApplication()
app.launch()
app.buttons["Hello, World!"].tap()
let heading2 = app.staticTexts["Two"]
XCTAssertEqual(heading2.label , "Two") // heading label
app.buttons["Hello, World #2!"].tap()
let heading3 = app.staticTexts["Three"]
XCTAssertEqual(heading3.label , "Three") // heading label
app.buttons["Pop to root"].tap()
let heading1 = app.staticTexts["Root"]
XCTAssertEqual(heading1.label , "Root") // heading label
}
A better test using accessibility Identifiers
func test_using_accessibilityID() throws {
let app = XCUIApplication()
app.launch()
app.buttons["button1"].tap()
let heading2 = app.staticTexts["Two"]
XCTAssertEqual(heading2.label , "Two") // heading label
app.buttons["button2"].tap()
let heading3 = app.staticTexts["Three"]
XCTAssertEqual(heading3.label , "Three") // heading label
app.buttons["button3"].tap()
let heading1 = app.staticTexts["Root"]
XCTAssertEqual(heading1.label , "Root") // heading label
}
Testing NavigationView Links
Here's some code for simple testing of XCUI Testing.
//
// ContentView.swift
// Nav_Example_Test
//
// Created by David on 2/6/21.
//
import SwiftUI
struct ContentView: View {
@State var isActive : Bool = false
var body: some View {
NavigationView {
NavigationLink(
destination: ContentView2(rootIsActive: self.$isActive),
isActive: self.$isActive
) {
Text("Hello, World!")
.accessibility(identifier: "button1")
}
.isDetailLink(false)
.navigationBarTitle("Root")
}
}
}
struct ContentView2: View {
@Binding var rootIsActive : Bool
var body: some View {
NavigationLink(destination: ContentView3(shouldPopToRootView: self.$rootIsActive)) {
Text("Hello, World #2!")
.accessibility(identifier: "button2")
}
.isDetailLink(false)
.navigationBarTitle("Two")
}
}
struct ContentView3: View {
@Binding var shouldPopToRootView : Bool
var body: some View {
VStack {
Text("Hello, World #3!")
Button (action: { self.shouldPopToRootView = false } ){
Text("Pop to root")
.accessibility(identifier: "button3")
}
}.navigationBarTitle("Three")
}
}
struct ContentView_Previews: PreviewProvider {
static var previews: some View {
ContentView()
}
}
Your Mission - see which test are brittle - change something - experiment...
Here's a new implementation code:
//
// ContentView.swift
// Nav_Example_Test
//
// Created by David on 2/6/21.
//
import SwiftUI
struct ContentView: View {
@State var isActive : Bool = false
var body: some View {
NavigationView {
VStack {
Text("It's a small world, afterall...")
.accessibility(identifier: "smallworld")
Spacer()
NavigationLink(
destination: ContentView2(rootIsActive: self.$isActive),
isActive: self.$isActive
) {
Text("Hello, World!")
.accessibility(identifier: "button1")
}
.isDetailLink(false)
.navigationBarTitle("Tap-Root")
.toolbar {
ToolbarItem(placement: .navigationBarLeading) {
Button(action: {}) {
Image(systemName: "bell.fill")
.padding(.horizontal)
}
.accessibility(identifier: "bell")
}
ToolbarItem(placement: .bottomBar) {
Button(action: {}) {
Text("Bing Me")
.padding(.horizontal)
}
.accessibility(identifier: "bingme")
}
}
Text("accessibilityIdentifier = button1")
.fontWeight(.light)
.font(.footnote)
.italic()
Spacer()
}
}
}
}
struct ContentView2: View {
@Binding var rootIsActive : Bool
var body: some View {
NavigationLink(destination: ContentView3(shouldPopToRootView: self.$rootIsActive)) {
Text("Hello, World #2!")
.accessibility(identifier: "button2")
}
.isDetailLink(false)
.navigationBarTitle("Two")
}
}
struct ContentView3: View {
@Binding var shouldPopToRootView : Bool
var body: some View {
VStack {
Text("Hello, World #3!")
Button (action: { self.shouldPopToRootView = false } ){
Text("Pop to root")
.accessibility(identifier: "button3")
}
}.navigationBarTitle("Three")
}
}
struct ContentView_Previews: PreviewProvider {
static var previews: some View {
ContentView()
}
}
XCUI Test improved
I've not been using XCUI Test for quite some time... they were too difficult to get working. It seems in 2022 that the Accessibility Identifier issue has been fixed. I see all the cool kids using it now.
