Mobile app testing is practiced to deliver customers and the app’s target audience a delightful experience. The question now becomes what goes on behind the scenes of the mobile testing of an application? This blog comprises of a synopsis of the subjects associated with mobile app testing.

Mobile Application Testing: What is it & Why it Matters

The process of thoroughly evaluating an application, created for a mobile device, is known as machine application testing. It involves the activity of evaluating the app while concentrating on factors like effectiveness, adaptability, stability, etc.

Why testing is important? Testing mobile applications is vital since it is necessary for an app to survive in the market. Post-release, it is important to ensure the app satisfies the technical requirements as well as the needs of the end customers. That is why, in the mobile testing phase, a mobile app is examined from all the UI, performance, and security angles.

Types of Mobile App Testing

There are a variety of Mobile applications that are introduced to the market every day. Amongst these, there are three different categories of mobile apps, and each category has a unique coding structure.

  • Native applications that are explicitly designed for iOS or Android devices,
  • Hybrid applications that are cross-platform and compatible with every operating system and
  • Progressive Web Applications that use standard web technologies like HTML and CSS to function on any device.

For these different types of applications, there are a few common testing models. Given below are the most popular ones:

1. Functional App Testing

Functional App Testing

Functional Testing checks whether the mobile application is working according to the predetermined requirements or not. The combination of manual and automated methods in functional testing is best suitable to check this. Functional testing is conducted at an initial stage of the testing process by individuals or groups involved in the app development. This is an important testing phase and a priority because the user will quickly uninstall it if doesn’t find it functional.

A functional test strategy for mobile apps usually assesses the following significant factors:

  • Core and business-critical features
  • Basic user flows
  • Taking action in response to disruptions [incoming calls, low battery, loss of internet connections, etc.
  • Payment portals
  • Warning signs

2. Performance App Testing

Performance App Testing

In Performance testing, an app is tested to see if it can handle a large number of users, database requests, or server removals. This requires testing the model under minimum average and peak user numbers, with adequate network coverage. Developers or testers undertake this testing in order to find any application bottlenecks or errors.

This testing is done beforehand to avoid uninstalls on the user end. If the user discovers the application is not functioning properly in accordance with events, he or she may become irate and uninstall the app in less than a minute.

A mobile app performance test strategy usually assesses the following significant factors:

  • App responsiveness and startup times
  • Memory data and data usage
  • Interaction with other apps
  • Network conditions and adjustments are ongoing.

3. API Testing

API testing

Application Programming Interface, or server API, is a common interface used by applications. An API facilitates data exchange between the separated software parts. A QA expert examines whether or not the response time between the API and server is accurate.

An API test plan for mobile apps should assess the following crucial factors:

  • Server data transfer
  • API calls
  • Server time-off

4. Usability App Testing

Usability App Testing

An app must be intuitive enough for users to navigate. Thus, usability testing counters users’ opinions on layout design and overall interaction of the app.

A usability test plan for mobile apps should assess the following crucial parts:

  • Consistency in design and layout between portrait and landscape modes
  • User flow logic
  • The interface’s intuitiveness of Graphic components’ positioning
  • Readability and simplicity of text

5. Compatibility App Testing

Compatibility App Testing

The screen resolutions, internal hardware configurations, operating systems, and software versions of contemporary mobile devices vary widely. As a result, an app is tested on as many different devices as feasible, so a product owner can be sure that it works on various smartphones.

A mobile app compatibility testing plan should assess the following crucial elements:

  • Performance & user interface on multiple screen sizes
  • Operating systems and browsers

6. Localization App Testing

Localization App Testing

It’s a well-known fact that the more people feel comfortable with your app, the wider audience you get. The process of localization testing can help in adapting the app to the target markets and increase reach.

The following factors are usually assessed by a mobile app localization test strategy:

  • Default language
  • Data format
  • Metric system
  • Text input parameters
  • Currency

Benefits of Mobile App Testing

1) QA experts examine solutions (apps) on actual devices rather than simulators to make sure they work as intended.
2) Testing enables experts to comprehend the feelings of end users and forecast whether people will keep using a product (app).
3) Deep analytics can help businesses build a good reputation and reach a larger audience through proper functioning and usability.
4) Testing can cut down on time, expense, and time-to-market. In the long run, it generates greater profits.

One must reach out for mobile app testing services to obtain more advantages. Their comprehensive services can give businesses impeccable solutions.

Mobile App Testing Challenges and Its Solutions

1. Device fragmentation

Device fragmentation is a significant challenge for mobile app testing because there are more and more active devices running an app. Teams of testers must guarantee that app must be installed on various operating systems and versions of the same operating system.

Solutions for overcoming device fragmentation:- It is simpler to use a cloud-based mobile app testing interface to:

  • Upload the application, with simply one click
  • Test the app on several iOS simulators and Android emulators
  • Monitor the apps’ quality
  • Count on the cloud for quick deliveries and other things

2. Varying screen sizes

Businesses create smartphones with different screen specifications, to appeal to a wider audience of customers. This necessitates the creation of apps in conjunction with every new screen specification released in the market. Developers now need to concentrate on mobile screen adaptation, including resizing and adjusting to various screen resolutions. Unless an application is well-tested, this can be difficult.

3. Battery usage

Testing mobile apps for heavy battery utilization requires testing for high battery consumption, which is difficult given the increase in battery-intensive apps. Stronger batteries have been offered by mobile manufacturing businesses as a solution, however, consumer discontent is still a problem. To ensure a fantastic user experience, apps must be tested to make sure they are not using too much power.

4. Browser Fragmentation

Even though your mobile application is a progressive web app, you must test it on popular browsers to make sure it functions properly.

5. Third-party integrations

Third-party integrations should be verified to guarantee they function properly in the current app context, due to the fact that they are not a part of the source code and have their own set of requirements.

Steps to Follow in Mobile App Testing

After compiling the checklist of testing, thereafter follow the given step-by-step process to conduct mobile application testing:-

1. Developing a successful plan and strategy

Making a plan and a strategy to implement is the first step of testing mobile apps. This stage is crucial since all subsequent steps rely on this one. This process entails determining the app type, setting the requirements, locating the intended devices, and performing additional tasks.

2. Recognising the necessary test type

Although every person’s mobile device is different, the ultimate objective should be, for the application, to run smoothly and support iOS and Android. It is required to execute a combination of manual, automated, and cloud simulator testing to obtain validated results regarding the same. Putting this into practice reveals all the flaws and faults.

3. Developing test cases and scripts

At this level, creating test cases for each app function is the main priority. The documentation consists of test cases of the app’s features and functions. Additionally, it includes a few exceptional cases that are also discussed.

A distinct suite of manual test cases and automated test scripts must be created depending on the situation. Identify the reusable automation scripts and tweak them as necessary.

4. Creating the testing environment

Follow these procedures to set up the testing environment:

Stage 1: Determine the type of testing for implementation

Manual and automated test cases for the ILL application must be run on each supported browser. Manual and automated test cases must be used for usability, functional, and compatibility testing.

Stage 2: Executing manual and automated testing

Agile testing is utilized to test the mobile application, with the developers releasing the product and the testing team conducting test cases in Quality Assurance. The new functionality is tested manually, and JIRA is used to record and re-verify faults and set acceptance criteria. The client confirms any issues and the application’s functionality during beta testing.

Stage 3: Beta Testing

Following regression testing, the quality assurance team re-verifies defects to ensure the application functions as expected on approved browsers.

Stage 4: Performance evaluation

The effectiveness of online applications can be evaluated using JMeter and increasing loads.

Stage 5: Testing in browsers

Real mobile devices and simulation tools can be used for browser testing.

Stage 6: Launch Plan

At the conclusion of the fourth week, testing is moved into staging to ensure the product is prepared for production and going Live.
