前言
自动化Test可以通过编写代码、或者是记录开发者的操作过程并代码化，来实现自动化测试等功能。接下来几篇我们就说一下该技术的使用。感兴趣的可以看下面几篇。
1. 自动化Test使用详细解析（一） —— 基本使用（一）
2. 自动化Test使用详细解析（二） —— 单元测试和UI Test使用简单示例（一）

源码
1. Swift
首先看下工程组织结构
下面就是测试部分源码了
1. AmountFormatter.swift
import Foundation
enum AmountFormatter {
private static let amountFormatter: NumberFormatter = {
let formatter = NumberFormatter()
formatter.minimumFractionDigits = 2
formatter.maximumFractionDigits = 2
return formatter
}()
static func string(from decimal: Decimal) -> String? {
return amountFormatter.string(from: decimal)
}
static func decimal(from string: String) -> Decimal? {
return amountFormatter.number(from: string)?.decimalValue
}
}
extension NumberFormatter {
func string(from decimal: Decimal) -> String? {
return self.string(from: decimal as NSDecimalNumber)
}
}
2. Account.swift
import Foundation
struct Account {
let name: String
var balance: Decimal = 0.0
mutating func updateBalance(by amount: Decimal) {
balance += amount
}
}

@ObservedObject private var viewModel = AccountsViewModel()
init() {
UITableView.appearance().separatorStyle = .none
}
var body: some View {

List {
ForEach(viewModel.accounts.indices, id: \.self) { index in
// swiftlint:disable:next multiline_arguments
NavigationLink(destination: UpdateBalanceView {
self.viewModel.updateBalance(at: index, by: $0)
}) {
AccountView(account: self.viewModel.accounts[index])
}
}
.onDelete(perform: delete)
}
.navigationBarTitle("BudgetKeeper")
// swiftlint:disable:next multiple_closures_with_trailing_closure
.navigationBarItems(trailing: Button(action: {}) {
// swiftlint:disable:next multiline_arguments
