Unit testing Swift code that uses async/await | Swift by Sundell
Articles, podcasts and news about Swift development, by John Sundell. Writing robust and predictable unit tests for asynchronous code has always been particularly challenging, given that each test method is executed completely serially, line by line (at least when using XCTest). So when using patterns like completion handlers, delegates, or even Combine, we’d always have to find our way back to ou
Unit testing Combine-based Swift code | Swift by Sundell
Articles, podcasts and news about Swift development, by John Sundell. Testing asynchronous code is often particularly tricky, and code written using Apple’s Combine framework is no exception. Since each XCTest-based unit test executes in a purely synchronous fashion, we have to find ways to tell the test runner to await the output of the various asynchronous calls that we’re looking to test — othe
私が（iOS エンジニアの）採用でコードチェックする時何を見ているのか - Qiita
2021-10-17 追加 弊社の Android 採用課題も公開されましたので、そのリンクを追加しました。 2020-05-18 追加 本日から弊社の採用課題がこちらに変更されました。これまではアプリをゼロから作成していただく課題でしたが、今後は既存のコードをリファクタリングしてもらう課題となりました。ただし我々が確認する項目はそれほど大きく変更するわけではありませんので、本記事の内容の多くは引き続き有効です。 ここ数ヶ月は、iOS のエンジニア採用のコードチェックにもよく参加していますので、そろそろ良さそうと思って、ここで私がコードチェックする時に一体何をチェックしているのかを共有し、皆さんの転職活動やキャリア設計に役に立てればと思います。 Disclaimer この記事の内容はあくまで株式会社ゆめみの iOS エンジニア採用のものです。弊社以外の iOS エンジニア採用や、弊社でも
How to write unit tests for SwiftUI apps
unit and acceptance testing, automation, productivity How do you write unit tests for a SwiftUI application? SwiftUI, with its declarative approach to UI development and its opaque types, doesn't lend itself to writing unit tests. Are UI and snapshot tests our only option? Should we generate multiple Previews for every behavior permutation of our views? The answer is simpler and doesn't require an
StoreKit Testing in Xcode 12: Getting Started
While building iOS apps is a fun process, testing in-app purchases, or IAPs, can be finicky and prone to errors. You used to first create sandbox testers, then log into your testing devices to test purchases in the sandbox environment. A tedious process that often caused unnecessary frustrations. With Xcode 12, Apple introduced local StoreKit testing in Xcode. Now you can test different IAP scenar
