Testing React Native Apps · Jest
At Facebook, we use Jest to test React Native applications. Get a deeper insight into testing a working React Native app example by reading the following series: Part 1: Jest – Snapshot come into play and Part 2: Jest – Redux Snapshots for your Actions and Reducers. Setup​ Starting from react-native version 0.38, a Jest setup is included by default when running react-native init. The following con

Real World Mocking in Swift
About the content This talk was delivered live in March 2017 at try! Swift Tokyo. The video was recorded, produced, and transcribed by Realm, and is published here with the permission of the conference organizers. Mocks allow us to write fast tests that do not mess with production data. Without OCMock, we will need to write our own mocks, but it does not have to be much work. In this talk from try

Bad Testing Practices · objc.io
I've been writing automated tests for a few years now, and I have to confess that it's a technique that still fascinates me when it comes down to making a code base more maintainable. In this article, I'd like to share some of my experiences, as well as the lessons I've learned either from others or via trial and error. After all these years, I've heard many good (and bad) reasons to write automat

Async Testing with Quick and Nimble
unit and acceptance testing, automation, productivity In the previous two posts of the Practical Testing in Swift series we had a look at how to test asynchronous code using XCTest, both when dealing with callbacks and delegates. In this post we'll see how to do that using Quick and Nimble, a pair of Swift testing frameworks. In case you are not familiar with them, let me introduce these two frame
Unit Testing in Swift 2.0: The Before and After Story
About the content This content has been published here with the express permission of the author. With great power comes greater responsibility. Unit testing superpowers in Swift help write better, more expressive code, but can be tough to get the hang of. In this talk Jorge Ortiz introduces unit testing and explains three scenarios of unit testing with Swift, providing you with practical advice f
Testing Swift's ErrorType: An Exploration
In this post, we explore the nature of Swift’s new error type, looking at the possibilities and restrictions for testing error handling implementations. We end with an illustrative example, and some helpful resources. How to Implement the ErrorType Protocol If we jump to the definition of the ErrorType protocol in the Swift standard library, we see that it doesn’t contain many obvious requirements
