The landscape of mobile applications is expanding in all industries in the modern world. Why? Billions of mobile users find these apps to be incredibly useful and businesses are willing to do whatever it takes to attract and retain this large group of mobile users by developing apps that appeal to them.

When developing mobile apps at break-neck speed, it is imperative to establish a mobile app testing strategy that is geared to help achieve the goals of the company and the needs of the client. Because testing is unavoidable before releasing any software product, testers are tasked with finding innovative ways to test quickly and at scale. However, being able to test on a wide variety of mobile devices and operating systems like Android, iOS, and Windows presents its own set of challenges in terms of cost optimization.

Due to frequent OS updates, the introduction of new device models, new releases to maintain competitiveness on mobile features, etc., testing must be performed more frequently. Automated testing mobile accelerates the process and reduces the number of mistakes that usually happen with manual testing. Of course, nowadays, there are a lot of automation testing tools out there, and it can be hard to choose the right one for your team.

In this article, Svitla System’s very own Person X, Person Title, will walk us through a curated and thorough overview of some of the best mobile automated testing tools that can help your business cut expenses and come out on top in the mobile app testing space.

What is Automated Mobile Testing?

Mobile apps very often have a complicated internal logic that needs to be tested very carefully for every change in the source code. Automated testing for mobile apps is such a powerful tool that there are projects that build all their QA system around it by covering each screen and each user workflow with it.

So, what is automated mobile testing? As the name suggests, mobile automation is "automation" that is done on mobile devices. And in the context of testing, automation is the process of testing an application automatically with tools, which helps cut down on testing time by using computers rather than people.

Why is Automated Testing a Must for Mobile Development?

Mobile automated testing has revolutionized software development and is largely responsible for the recent app expansion. Let's have a look at the key advantages of automated testing that allow businesses to speed up their testing and development processes.

Enhancing Regression Testing

Having to manually test for bugs in software updates is a time-consuming operation. To validate that a mistake has been solved, testers must perform testing multiple times using the same set of test cases. Developers and testers have long found this to be a major source of frustration.

Testing Across Multiple Environments

It is crucial to test applications for cross-platform compatibility early on in the development cycle. Automated testing allows testers to test a mobile application across several platforms, operating systems, and devices. This is particularly helpful as testers only need to create a single universal automated test that can work on multiple environments without the challenges of having it be compatible across diverse platforms.

Test Cases Can Be Reused

The ability to reuse test scripts is a significant benefit of automated testing because creating test cases is time-consuming and labor-intensive. When putting in place a cross-platform test, testers must always write fresh test scripts for each new operating system or device. Because automated test scripts may be reused, testers can make better use of their time.

Improved Test Results

By analyzing the data produced by test automation technologies, testing teams may keep tabs on the status of the entire testing procedure. By using these insights, engineers can minimize the likelihood of making mistakes.

Scalability

Automated testing requires much less resources and people involved, which makes it easier to scale. In stark contrast, manual testing requires a lot more people because it involves a high volume of instances. Automated testing makes the process more scalable and with very scarce human involvement.

Best Tools for iOS Automated Testing

XCTest/XCUITest

Platforms: iOS exclusively.

Available programming languages for testing: Limited to build with Objective-C or Swift.

Background: Like Android Studio, Xcode gives developers iOS automated testing with plenty of options for testing software, which can greatly help to make the software more stable. Also, Xcode comes with XCTest and XCUITest, which are very helpful tools for making and building better software. Apps that have been well tested, whether at the unit level or at the user interface (UI) level, improve the user experience and make it easier for people to use those kinds of apps.

Documentation/community: Professional, sleek, and thorough, this iOS-based testing framework’s documentation delivers plenty of value to testers thanks to its definitions of test cases, methods, test assertions, UI tests, asynchronous tests, and much more. See documentation and resources here.

Getting started: Get up and running with XCTest here.

Pros:

Easy to use and only needs knowledge of Swift
Since the grammar is similar to English, it's easy to read and write tests in this language
You can write unit tests, performance tests, and even tests to see how well your app works with other apps and services with XCTest

Cons:

Most of the time, Apple builds everything so that it can only be used on its own tools, devices, and environments. Since this makes sense when testing APIs and functions as a whole, many testers prefer cross-platform test automation frameworks so that they only need to write one test script that works on both Android and iOS.
Developers can only use Objective-C or Swift.

KIF – Keep-It-Functional

Availability: Free.

Platforms: iOS, exclusively.

Available programming languages for testing: Objective-C.

Background: KIF, which stands for "keep it functional," is an iOS integration test framework that uses XCTest test targets and is closely related to them. Any subclass or XCTestCase itself can be used to run KIF tests. KIF makes it easy to automate iOS apps by taking advantage of the features that make the OS accessible for people with visual impairments.

Documentation/community: In honor of its name, KIF’s documentation is also easy to follow and understand, providing users with plenty of resources around projects, security, releases, and more. See KIF’s resources here.

Getting started: Get up and running with KIF here.

Pros:

Easy to learn. iOS app developers can choose between Swift and Objective-C.
KIF works directly with Xcode projects, so testers don't have to install any packages, set up any extra servers, or work with any other instances.
KIF offers user-like inputs, and all automation events and interactions are similar to how a real person would use the app being tested.

Cons:

Can be buggy at times, especially with newly-released versions of iOS.
