Smartwatch App Testing – watchOS

watchOS title - Adventures in QA

This is the second post of my smartwatch app testing series. In this post I will write about Apple’s watchOS. Apple introduced watchOS together with the first Apple Watch in April 2015. WatchOS is already available in the second version watchOS 2. If you are new to this smartwatch app testing series, in the first post I wrote about Tizen OS and the Samsung Gear S2 smartwatch.

Together with the watchOS release, Apple also released the watchKit for developers, an SDK to develop apps for the smartwatch. Apple Watch apps can either be written in Objective-C or Swift, the new open source programming language from Apple. If you want to get started with watchOS, I recommend you to read the following links:

If you want to setup watchOS on your system, you can download the latest version from here. To get an overview about the architecture and the application life cycle of watchKit apps read this link.

Smartwatch App Testing – Tizen OS

Tizen OS - App Testing

In the first blog post of the smartwatch app testing series I will write about Tizen OS. Tizen is an open source operating system built from scratch, developed and supported by a community of developers under open source governance. The main purpose of this new operating system is to address the needs of all different kind of stakeholders of the mobile and connected device world. This includes mobile device manufacturers, mobile operators or application developers. Tizen OS can be used for different use cases and scenarios, so called Tizen profiles. There are profiles for Tizen Mobile, Tizen TV, Tizen IVI (in-vehicle infotainment) and Tizen Wearable. For my series I will focus on the Tizen Wearable profile and will provide you with useful information to get to know this section of the Tizen operating system.

Tizen OS is a pretty new operating system and there are not as many manufacturers out there using Tizen Wearable on their smartwatches as Android Wear for example. Therefore, I will focus in this post on the Samsung Gear S2 smartwatch. If you want to get started with Tizen OS, I recommend you to read about the operating system on If you want to install and use the development SDK download it from here. In the getting started section you get all the details about the SDK. If you want to get more information about the architecture of Tizen, read more about here.

Smartwatch App Testing

Smartwatch App Testing - Adventures in QA

Smartwatches are available since a couple of years and they are becoming more and more important in the wearable industry. In 2015, more than 24 million smartwatches were sold worldwide and this number will likely increase in the next upcoming years. The first editions of the different smartwatches weren’t that mature and offered not that many apps and functionality. However, this might change in the near future and smartwatches can become the next big thing and will extend smartphones and tablets with useful functions. It may happen that you or your company decides to write an extension for your existing Android, iOS app also for the different smartwatch operating systems.

This extension to the mobile apps add more complexity to your environment from a development and testing perspective. In order to handle the new complexity and the challenges this series will help you to understand the different smartwatch platforms and provides you with useful testing ideas to handle this situation.

In the upcoming series I will focus on the following smartwatch platforms:
