Top App Testing Techniques and Testing Scenarios for Web and Mobile

Introduction

The technology industry is rapidly evolving, leading the development of new web and mobile applications daily. This implies an increase in the need for web and mobile application testing services. This is why app developers use a variety of app testing methods to evaluate both mobile and web applications to stay competitive in this fast-paced technological environment and keep their apps well-integrated and flexible to changes. A complete app testing strategy is the only approach to assure that applications are fully functional. Testers accomplish this by following various test scenarios that the app is subjected to and employing the most appropriate app testing techniques. We’ll talk about mobile and Web app testing techniques, as well as various testing scenarios, as we progress through this blog.

Mobile App Testing Techniques and testing scenarios

We all know how mobile apps have become an integral part of today’s world. Statista shows that the number of mobile applications downloaded worldwide will reach 230 Billion by 2025. A majority of the world’s population is using mobile phones. To ensure that apps function properly, it becomes important for QA engineers to maintain the quality and functioning of mobile apps by performing mobile app testing to strengthen their usability, stability, and functionality.

What is mobile app testing and what are the various techniques used to perform mobile app testing? It is a process of evaluating mobile apps and websites by testing their compatibility across different devices and enhancing their performance in different scenarios. Different firms create different mobile applications based on various business requirements. The choice of mobile application testing techniques depends on the type of mobile application. There are native, mobile web apps, hybrid apps, and progressive web apps tested either on emulators or real devices.

Mobile and Web application techniques and scenarios:

The testing techniques for web and mobile apps are somewhat similar but there are some key differences as well. Let us look at the various Mobile App Testing Techniques broadly used by the testers:

1. Documentation Testing: This app testing method is used in the very early stages of mobile app testing when the testers examine the wireframes, navigational charts, and other elements for consistency and accuracy. All the issues are resolved before the actual testing starts. The documents related to functional requirements, product requirements, test cases, test plans, test coverage, and traceability matrix are covered in this testing stage.

2. Functional Testing: This mobile and web app testing technique is used to check all the specific functionalities of the mobile application to ensure that there is no error in the app and the quality of the app is maintained. Testers should keep the following factors in mind before performing functional testing:

-Business functionality of the app (like banking/ online shopping/ gaming/ social/ food ordering, etc.)

-Target Audience (consumer/ education/ enterprise/travelling, etc.)

– Application Distribution Channel ( App stores — Apple and Google Play/ Direct distribution, etc. )

Here is a list of the test scenarios that need to be covered in the functional testing stage:

-Validate that all the mandatory functions are working as specified.

-Check whether the mandatory fields are displayed distinctly from other fields.

-Check if the app works well in the specified device and OS versions.

-Check if the app downloads and installs smoothly for all users.

-Check if the device can multitask when the app is running in the background.

-Check if the app restricts the functioning of other apps on the device once installed.

-Check if the social networking features on the app work as expected.

– Check if the app accommodates payment gateway transactions like VISA, MasterCard, etc.

– Check if the page scrolling in the app works as expected.

-Does the app notify network error messages when there is any network issue?

-Is it easy to navigate between the relevant modules in the app?

-Validate if the truncation errors are within the manageable limit.

-Validate that the app resumes the last operation whenever there is a system crash or hard reboot.

-Validate that the app performs the auto start smoothly as specified in the requirements.

-Check whether the app performs well in all network versions of mobile i.e. 2G, 3G, 4G, and 5G.

-Check to see if the application provides a user guide to the users.

-Check to see if the app works as per the specified instructions in case of stop/start the action.

-Check to see if the app minimizes automatically when there is a phone call.

-Check to see that your phone SMS service is functional (store, process, receive SMS) when the app is running.

3. Performance Testing: This app testing technique assures that the app, whether web or mobile, runs well under any stress or workload situation. It is performed to validate how stable the app's performance is in terms of operability, resource utilization, etc. in extreme working conditions.

-Mobile app performance testing is performed to check its stability for normal vs. extreme loads.

-To check its ability to sustain a continuous period of stress so that it doesn’t crash.

-To check the App’s performance while handling a huge amount of data is also tested.

-Concurrency testing is also run to check the performance of the app in case of multiple user logins.

Here are a few of the test scenarios in performance testing:

-Validate how the app performs in different load and stress conditions.

-Check the app performance in the given network coverage when the user levels are at peak, average 7 and the lowest.

-Validate the performance of the existing client-server configuration set-up.

-Validate application response time as specified.

-Evaluate if the battery life performs well in extreme load conditions while using the app.

-Evaluate the app performance during the network switch from WiFi to 2G, 3G, 4G or vice versa.

-Validate app performance in intermittent connectivity.

4. Security Testing: This app testing technique is used to check how secure the app is against any security flaws, loopholes, and risks caused by viruses, malware, hackers, unauthorized access, etc. This type of testing will ensure the app’s data and network security requirements follow the set guidelines. Here are some of the testing scenarios to cover in security testing:

-Check to see if the app security system asks users to set a strong password.

– Ensure that the user data like login credentials, passwords, payment credentials, etc. are secured

– Ensure that the app does not allow any data access without user authentication.

-Ensure protection against Hackers, CSS, SQL injection, Denial of service, and distributed denial of service attacks.

-Check to see if the insufficient session expiration impacts the app.

-Check to see if the app prevents any insecure data storage in cookies, and the cache memory of the application.
