Mobile app testing is an intricate process that involves the right selection of automated tools, devices, frameworks, and simulators to meet user’s expectations. In today’s technological world, a mobile phone is not just a tool for communication anymore, but it has completely transformed into a multi-functional device. Being a device that comes with various platforms, technologies, networks, browsers, and operating systems, it comes with a lot of mobile applications too that has converted the world into a smaller place with quicker provisioning of products and services with better networking. But it has put the developers and testers tasks under strain.

Digital transformation is making rapid progress in our lives. And mobile applications have become its crucial lever. We need to have better quality apps and that needs conducting rigorous mobile application testing. Automation testing or quality assurance is a software testing technique that uses an automation tool to conduct an automation test, which is used to identify any defects in the system of an app by the automation tools.

Quality assurance is not only essential for the success of an app while being in the development stage, but it is also useful in post-development evaluation. Below is an informative step-by-step guide on the mobile application testing process.

Guidelines on the Mobile App Testing Process

Stage 1: Planning

After the completion of the development stage of the app, reviewing the strategy steps involved in the mobile app testing automation is crucial. Below are the factors to be considered –

  • Does the app interact with other apps?
  • Are all the features functional?
  • Is the app Native, Hybrid, or Mobile-web?
  • Is the app’s testing limited to the front-end?
  • Does the app include back-end testing?
  • Is it compatible with a variety of networks?
  • How frequently space/data based Usage is
  • How is load maintained?
  • Is the application flow affected by any change in phone status?

Stage 2: Identify Mobile Application Testing Types

The developer must be decisive on the specific test to conduct on a device in terms of compatibility, performance usability, functionality. Also, the developer must choose a targeted device in terms of the type of devices the app will support or decide to test the apps on real devices or emulators.

Stage 3: Test Case and Script Design

In this stage, we make a case document for each feature and functionality, such as battery usage, memory, data requirements, and app speeds. It’s also critical to know which combination of automation or manual test to conduct.

Stage 4: Manual and Automated Testing

The fourth stage involves the execution of both manual and automation tests and Basic functionality done to confirm the lack of breakages.

Stage 5: Usability and Beta Testing

This stage requires the maintenance of a cross-platform matrix to ensure that the coverage is achieved by beta testers, considering the essential functions tested. After the in-house test, the beta version of the app is ready for market release. Type of beta testing that we perform at Scalex are –

Compatibility testing – This test involves mobile devices from different platforms having different operating systems compatible with the app.

User Interface testing – This test consists of checking usability issues like navigation flow, test menus, options, settings, etc.

Interface testing – Testing consists of testing menu options, navigation flow, buttons, bookmarks, etc.

External factors testing – Consists of testing the app with other device features like networks, device settings, phone calls, SD cards, etc.

Accessibility testing – The test involves the accessibility of the apps in terms of demographics.

Functional Testing – The test targets vital features such as installation, upgrade tests, sign up and log-in tests, operational tests, offline Testing, etc.

Stage 6: Performance Testing

This test focuses on the app performance in terms of battery consumption on devices, the flexibility of switching, and working efficiently on different network coverage like 2G, 3G, 4G, or even WiFi.

Stage 7: Security and Compliance Testing

Users need to have all their data secured from threats. This test involves validation of SQL injection, session hijacking, data dumps, SSL, and packet sniffing.

Apart from the tests conducted, the developer must ensure that the app has the following; security certificates, fewer restrictions for users who forgot login details, and lastly, secured network protocols.

Stage 8: Device Testing

The device testing involves all the apps compatible devices being tested using the cloud or physical devices or using the testing tools.

Stage 9: Control and Summary

This final stage of Testing usually involves polishing up to stabilize the app by rectifying small defects; once the control test gets completed, the app is officially made available to the users.

Test Summary Report

The summary is an official comprehensive report done to show the entire process. It’s should always include the following information:

  • Important information uncovered during Testing
  • Quality of Testing
  • Quality of the mobile app
  • Statistics from the incident reports
  • Different types of tests performed
  • Where the app is fit for use
  • If it meets all the requirements

After the intensive evaluation, Scalex Project Manager decides whether to release the app to the final users or not.

6 Tools for Mobile App Testing used by Scalex

1. Selenium

Scalex uses this tool, which is an enhanced software. Not just a single instrument, selenium is a free open source testing automated suit used to focus on automated test web-based applications.

2. Appium

Appium is a tool used by Scalex, and it is an open-source automated tool used to test mobile apps. Native, mobile webs, and hybrid apps tested with Appium using a web driver library.

3. Jmeter

Jmeter is a tool useful for load test running, plan to build, and load analysis test. Result viewing is also allowed using GUI mode, to add to that, it also allows you to manually create test plans and also choose from a variety of templates.

4. Pytest

It is a tool used to test frameworks that allow developers to write test codes by using python. Pytest is mostly used to write tests for APIs, but it is a tool that can also write a database or UI-based system, among others.

5. Soapui

Scalex is also known to use this popular and leading open source cross-platform tool useful for API testing. It allows developers typically to carry out regression, load tests on different APIs, and also automated function.

6. Jest

Jest is also one useful tool that is an open-source JavaScript code library, usually maintained by Facebook. It’s well-known for performing react code testing, considering it has strength in snapshot testing. Jest can also quickly test any JavaScript code.

5 Challenges of Mobile App Testing

Mobile app testing is usually a daunting task when compared to Web or Desktop apps. This is because of the complexity of the Testing involved. Below are the five main challenges of mobile app testing-


The automation test is based on the decision the operating system belongs to, it can be free or paid, none the less you ask yourself if it’s worth it in terms of performance delivery, making it a challenge for most of the app testers.

Network compatibility

The app tester needs to make sure that the app is not only compatible with Network connectivity but also works efficiently in all the networks, To effect this, the tester needs to cross-check the app on all the systems available in the market.

Changing Market

The changing device trends in the market keep the testers on their toes as they always have to stay updated with the current testing innovations, which include all the new functionalities and testing methodologies.

Building User Experience

For the apps to be successful, a highly competent team of experts is mandatory that includes designers, analysts to developers. Also, investing in market research is critical in terms of keeping up with dynamic users and changing trends.

Device-based Testing

The device-based Testing usually is costlier and the app’s performance is checked using a variety of devices. Also, you need to keep up with the current device updates is also essential; app testers, therefore, need to have a test lab with all the variety of devices for Testing.


In conclusion, automated testing is reliable and highly versatile. It is mostly used for software testing as it supports the execution of repeated test cases. At Scalex, we help clients accelerate mobile app testing success. Clients are guaranteed to end up with a fully functioning product; Our mission is to deliver solutions allowing customers to work their full potential.
