Without a doubt, your mobile phone is far more than a “just-to-make-a-call” device. It is your multipurpose personal assistant for everyday use. No wonder that the mobile app market is a zone of constant competition growth.
App development companies catch current user requests to offer an effective solution right away. However, the users are rigorous about low-quality apps, so fast release is never a great idea. To make an app truly competitive, it must undergo a profound QA strategy.
This article below shows the mobile app testing process behind the scenes.
First and foremost, your mobile application should work as per the initial requirements set. Functional testing encounters industry and services your mobile app is designed for (e.g. games, banking, dating app). Once the business area is identified, it’s time to focus on your target audience (education, health, consumer) and indicate the distribution channel of your app (e.g. Google Play, Apple Store).
Usually, a combination of manual and automated methods works fine while conducting this testing type. The earlier testers check an app for functionality, the faster will you release it on the market.
QA engineers test the mobile app behavior under certain performance requirements. In particular, an app should handle a huge number of users or database server removal.
QA specialists ensure an app works under different although expected load conditions. They determine whether the app supports a minimum, average, and peak user levels with the appropriate network coverage. The response time should also be appropriate when the app handles the projected load volumes.
While checking mobile app performance, sofwtare testers also pay attention to its behavior when switching to WI-FI or 2G/3G network.
Apart from load requirements, testing focuses on device performance. These are the standard scenarios questioned by QA engineers while checking device behavior:
Users especially value this performance parameter. Good news if your app opens in 2 seconds max. after the user taps on it.
Memory consumption might increase if an app includes certain features (e.g. push notifications). If an app consumes too much memory, it is better to think over some implemented features before it goes on the market.
A mobile application may come pre-installed on the device, or the users may have to download it from the store. The installation and update processes of your app should run smoothly without breaking other apps already running the device.
Once you get back to your app after a while, it should remain the same as you left it in the back. The correct scenario prevents data loss and users don’t have to enter the data again. That is why the testers work thoroughly on this matter.
Often, applications interact with the server via API. Application Programming Interface is a set of background rules the application performs by. It enables data exchange between the separated software parts. So, the aim of QA here is to determine whether the response time between API and server are correct.
Once the server sends data, an app should efficiently handle it. The time for data load shouldn’t be long, as it slows down the overall app performance.
The number of API calls to the server should be minimized. In some cases, several API calls work for the same functionality. However, the lower number of calls, the better performance of an app.
There are times when the server is unreachable. However, the testers make sure the data isn’t lost and stores in the native database.
When launching an app, one must be clear with the product target audience and preferences of app end-users. The role of UI and UX to be intuitive enough for your users to navigate the app. Thus, usability tests encounter users’ opinion on layout, design, and overall interaction with an app. That is why it is performed manually to ensure the app is convenient.
Some of the priority aspects to check via usability testing:
The first question that might have come on your mind might be like “Why test mobile apps for compatibility?” The thing is that modern mobile devices have many version updates, changing screen resolution, size, and hardware so that the users get interested. That is why an app undergoes testing across all devices to ensure its desirable flow.
At this stage, QA engineers continue working with a user interface and check if it is per screen size of the hardware. They ensure the text is readable and accessible for the user with any device. Remember, when an app minimizes or suspends because you receive a call? That means that app running synchronizes with call functionality and compatibility testers have checked it.
The more people feel comfortable with your app, the wider audience you get. Localization testing helps to customize an app per targeted countries and language peculiarities. Default language, date format, currency are the common aspects to check while doing localization testing.
The tools for the effective mobile app QA vary by mobile OS or device. So, if you are confused among them and doubt which is the best, you’re not alone 🙂 To help you, we’ve prepared the list of our favorites.
This is the most common automation tool for testing mobile apps. Surely, it is also the simplest in execution for developers and QA experts.
Since Appium supports Chrome app on Android and Safari on iOS, it is a quality cross-platform automation tool for native, hybrid, and mobile apps. This feature enables QA engineers to write tests on several platforms, choose the test practices and frameworks that suit best for the project.
Moreover, Appium delivers access to APIs, test code, and data. Therefore, it automates any mobile app regardless of the programming language.
The tool runs tests on the devices connected to emulators or a PC. With the help of in-built APIs, Monkey Runner controls a device without Android code.
Robotium is a perfect tool for writing powerful black box test cases to test Android apps. It helps to make strong test cases and execute them fast. Moreover, Robotium supports testing on real devices saving the usual test cases execution.
The tool fits for iOS and Android app testing, helps to create and run UI tests for hybrid or local mobile apps. QA and programming experts believe that the toll is one of the quickest methods to tests apps with various OS versions, devices, and screen resolutions.
With Eggplant, QA engineers run tests from users’ perspective (UI). It enables checking image and text recognition without focusing on the software code. This is a visual testing tool with a simple interface to write the test scripts.
The tool contains three components: IDE, Agent, and scripts. IDE helps to record and playback the test scripts; Agent is a library to add and start testing, scripts help to check the functionality of an app. Thus, MonkeyTalk is a powerful functional testing tool that automates a wide range of tests – from smoke to data-oriented, suits for Android and iOS app testing.
Although used by diverse audiences, Lightshot is one of our favorite screening tools. It cannot record videos, but it is perfect for screen capturing. Besides reliability and quick response, it has several saving options. One of the best things is that you can use Lightshot as a Google Chrome extension without downloading and installing the app.
When testing mobile apps and games on Android, you can use DU Recorder. It is a functional tool that allows capturing of screen activity and editing videos. For iOS, the native recording tool will do just fine. It comes with fewer features but still covers the basic needs of a QA team.
Today’s world is delighted about tech innovations, although developing a truly useful application is never easy. But that’s not the reason to give up your ideas! Be it a fitness assistant, a funny game, a messenger or a bookstore – just keep your app of the best quality possible. Get inspired and inspire others with your innovations!
