The mobile application industry has become a very popular and breakneck-growing business in the past couple of years. The number of mobile apps downloaded in the year 2020 was more than 142 billion. The mobile application industry has been booming with full prominence. The amount of time spent on mobile applications increased significantly during COVID-19 due to remote work and recreational activities performed with the help of mobile phones; the demand for new and better mobile applications is ever increasing! 407 billion dollars- that’s what the mobile application industry is projected to be worth by 2026. So, providing a best-in-class quality mobile application experience to the target users is very critical. Hence, it has become very crucial to test mobile applications to sustain and thrive in this ever-growing business industry. Therefore, here we explain mobile app testing for 1st time app developers.

But first, let’s understand the meaning of Mobile Application Testing: –

A high-end and exquisite mobile application experience for target users is critical in today’s competitive market. If you fail at providing, customers will opt for another mobile application promising a much better experience than yours.

Examining the functionality, usability, consistency for errors and performance of the mobile application is the purpose of mobile application testing.

It is also a kind of A/B testing. This requires beta users/testers to use and provide feedback on apps or new features added to an existing mobile application. The feedback from the beta testers can either be positive or negative. Necessary changes are made in accordance with the feedback received. And if needed, even eliminate some features from the mobile application. Moreover, all this is done before the new update or mobile application is made available to everyone else to use.

As a result, this ensures that only a high-quality mobile application experience is guaranteed and delivered to target users

Mobile App Testing Guide For First Time App Developers

Steps for mobile app testing for 1st time app developers

1) Decide on Test Coverage

Before beginning mobile application pentesting, you will have to decide what you want to cover during the test for your application across mobile phones and OSes. Test coverage can cover many aspects. Strategic test coverage has a wide range of parameters consisting of the appropriate mixture of devices and OS variations to cover all requirements of your app testing.

Basic testing coverage should consist of:

– Device varieties

-Different OSes

-Multiple testing options

-Different test durations -Focus on general execution window

2) Frequent consultation with the users

Considering you are developing a mobile app for the first time. During mobile app testing for 1st time. you have to consult regularly with testers or users of your app. This results in deep insight into how your app feels to the users.

Moreover, multiple users or testers are required to perform mobile app testing. Thereby, you ensure that your app satisfies multiple audience types, rather than a single user base type audience.

3) Plan of mobile app testing

There are two basic types of testing available for any given IT product. Namely, Manual and Automated testing,

Manual vs. Automated: Recently, companies have been opting for both manual and automated testing to optimize and not neglect even a small error during mobile app testing. Automated testing eliminates repetitive operations required to perform during manual testing. However, the drawback being the tester must continuously write and update the test script accordingly; otherwise, small errors are missed.

Hence, most companies use both manual and automated tests to perform for the best security and user experience.

Writing Test Scripts: According to your test method, you first need to write the test scripts manually, then convert them into automation scripts later.

By contacting a QA and testing partner, you can be free from this hectic work.

4) Prioritize security testing

For 1st time app developers, the security parameters of the app should be intact. The mobile app must be fully secure. From penetration, QA, usability, to functionality testing, each and every test must focus on the security aspect of the mobile app.

Moreover, testing of the communications between the app and servers should be tested for vulnerabilities as well!

5) Executing test scripts

Execution of those testing scripts based on your test coverage is the next step. DevOps team conducting the tests generally uses the continuous integration (CI) or continuous delivery (CD) procedure while testing the mobile application.

6) Resolving detected threats

Completion of execution of the test scripts enables us to trace and resolve any application errors detected. A good QA team considers this a top priority.

-Low: App is functional and has no huge impact on app UI.

-Medium: Unsuccessful at achieving the app’s intended functionality.

-High: The application’s critical functionality has stopped working. All the other features of the application are still working.

-Blocker: Mobile application testing has resulted in the blockage of the app, and the user won’t have anything to work on.

7) Test early, test regularly

1st time, developers tend to make mistakes while coding. Therefore, testing done from early stages of app development leads to a safer and smoother mobile app.

Moreover, with multiple users and testers, you can gather a plethora of detailed information about the mobile app.

Conclusion`

Now, having explained mobile app testing for 1st time app developers. You grasp the importance of it as well.
