According to Bizreport, around 77% of mobile users are concerned about the app’s performance. This means the app’s performance is one of the most crucial factors which you need to consider while developing a mobile app.

But how would you determine whether your app is performing to the expectations or not? For this, executing mobile app testing by quality analysts during the app development process is essential. Hence, we have created this complete guide with the help of our mobile app testers.

Let’s get started.

What is the Importance of Mobile App Testing?

To understand why mobile app testing is important, let’s discuss a scenario. What if a user is making a purchase on your mobile app and the amount has been debited from your user’s account, but the application shows the failure of the transaction. Don’t you think this incident will leave a bad impression on the user’s mind about your application?

Here are the benefits of proper mobile app testing:

  • Make sure everything is working properly for the end-users so that you focus on monetization instead of resolving bugs and complaints.
  • Testing a mobile app on real devices reduces the chances of rejection from app stores and brings your app faster in the marketplace.

Apps with any UI UX issues, crash reports, or security breaches lead to the uninstallation of mobile applications from the user’s mobile device.

Mobile Application Testing Process

Here is the testing process our QA team follows before launching mobile applications.

Requirement Analysis to Understand Client Expectation

This is the very first stage where a quality analyst gets involved to understand the project requirements. It allows testers to clear the queries of application flow and requirements in a better way.

Requirements analysis is an important factor and directly impacts the success of the project. Knowing the clear requirements helps our testers to understand the expectations of the client.

Our QA also determines the criteria based on different questions for testing the application. And we have listed down some of the questions below:

  • Does the application have all the functional features?
  • Is the mobile app native or hybrid?
  • Does the application include back-end testing?
  • What is the load on handheld mobile devices?
  • Does the application work as designed whenever it is functioning?

Once the criteria are determined, then the QA team moves further to create the planning of the test cases with documentation. It allows them to set the target and makes the methods clear before moving to the actual testing process. This allows completing the product or project testing within the deadline. This helps the team to avoid delays in mobile app release on the app store market.

Defining the Test Cases and Documentation

In this stage, our QA team creates documentation of the test cases of the mobile app testing. With this, we divide the test process into small sections. While creating the test cases, we consider all possible positive and negative scenarios.

Creating a document lets our QA team define the scope of mobile application testing. Parallelly, identifying the testing types is critical, so our QA team gets a clear idea of what they will do in the whole testing process.

For example, if the design of the mobile application is getting ready, then we start writing the test cases of the graphical user interface of the mobile application. It enables the team to check whether the application is performing as expected or not while it is in the development phase.

How does our QA team create the test cases of the mobile application?

Depending on the SRS (Software Requirement Specifications), our QA team conducts the analysis and creates test cases of the application. The QA team prepares the test cases depending on the functionality and features mentioned in SRS. Writing test cases is all about “What are we going to test in the application?” and “How are we going to perform the tests on the application?”.

Once the test cases are written, the document is shared with the project manager, developers, and business analyst team. This helps to ensure that the process is going at its pace according to requirements and feedback is added at regular intervals.

While creating a document of test cases, the QA team ensures the test cases are written by considering the WBS document as well.

In fact, this is the reason many of our clients have praised us for our app development services. Check this testimonial from Ashish Fernandez.

Creating Sections to Perform Testing of Mobile Applications

Before we actually start working on a project, we divide the project into different modules. It enables the team to complete the project in the decided timeframe. According to that, the test cases are divided into two sections of development. First, designing the mobile application, and second, developing functionalities in the mobile app.

In the initial stage, our QA team writes test cases on the UI designing and navigational phase. Before moving to development, the design and navigation of the application are tested. If both the stages work properly, then only the team will work on developing functionalities.

Executing the Different Types of Testing in Mobile Application

There are 11 types of testing that our QA team performs parallelly during the development of the mobile application. To give you an in-depth idea about each type of testing, we have described it in the following table.

Testing Type Description
Functional Testing · Enables to check mobile application specifications

· This is one type of black-box testing that allows doing mobile testing on functional requirements

· Testing to check the validation of inputs against the determined functional requirements

· This testing mainly focus on primary functions, basic usability, error conditions, and accessibility

· This testing can be done manually as well as automation

Unit Testing · Various coded individual components are validated if they are functioning properly

· Unit testing is executed to check the piece of code if it’s logically working accurately by software developers

· Ensures software code is performing as expected

· Unit tests help to fix bugs of code at the early stage of the software development life cycle

Integration Testing · The different software modules integrated logically and tested as a group

· Helps to find the defect in code during the interaction of different software modules

· Generally there are different approaches to perform integration mobile testing, such as big bang, top down, bottom up, incremental

· Ensures that all the different modules are working properly

Usability Testing · Allows testing user interface to ensure that it is user-friendly and easy to use

· To measure the competence and user’s convenience of using mobile applications to match its expected results

· Ensures the application’s look and feel is appealing to users with ease of navigation

Compatibility Testing · To know application’s compatibility on a mobile device

· Allows identifying that mobile app is working stably on different platforms and environments

· Helps to know if a mobile app is compatible with different hardware, networks, operating systems, browsers, mobile devices, and service providers

Interruption Testing · This test is performed to know whether the application’s state remains the same while interruptions

· It can be applied to any mobile web app, or mobile application, web application

· Allows QA team to check on how a mobile application reacts to interruption

· Helps to improve the performance of the app and escalate the errors during interruption, such as app crashes and unnecessary loading

Network Testing · Network configuration testing allows checking whether the mobile application is working properly with different networks like 2G, 3G, 4G, 5G, and Wifi or not
Reliability Testing · Reliability test allows knowing QA team whether the mobile app is reliable to perform with the purpose it is made

· This test is conducted to identify the mobile app’s ability under certain conditions and helps to know the issues on design and software functionality

· Allows the QA team to ensure the quality of the software application on which users can rely, and it ensures the standardization of the product

Localization Testing · Performed to know the application’s behaviour in a certain culture or locale

· Two majorly affected areas through localization testing are content and UI

· Helps to customize the mobile application as per target countries

· Usually in localization tests UI, language vocabulary, currency format, date & time for that specific country

Orientation Testing · It allows knowing whether the mobile application is performing on the landscape as well as on portrait mode
Regression Testing · Confirms that recent code changes are not affecting the previously build features and functionalities

· Needed for this testing when there is a requirement for changes in the code of an application

· There are three types of regression testing – unit, partial, and complete

· A testing process in which existing tests are reperformed to know that old functionalities are working fine

Tracking Issues Detected in a Mobile Application

While performing the testing in a mobile application, the QA team tracks and keeps a record of the issues which are found in the mobile application. Certainly, it ensures issues found in the mobile application do not get missed while resolved. For this, our QA team uses a Mantis bug tracker tool to report the issues and further those issues are assigned to a respective developer.

Once the developer gets the issues, then s/he starts resolving the issues. After resolving the issues, the developers again assign back the application to the testing team for verification.

Moving ahead the tester authenticates detects found in a mobile application and leaves comments (closed, reopen) in the tool. It makes things easier for developers and the QA team to manage and work simultaneously without missing out on any critical problems of the application.

Build Release of Mobile Application To Client

Before giving the build to the client, our QA team makes sure to create the release notes, if any. Moving further, the project manager shares the build (version) with the client along with the release notes.

Thereafter, the client checks the application to make sure everything is in line with the expectations.

Get Feedback from Client

In most cases, our sent build is accepted by clients but sometimes we get suggestions if the application’s functionality doesn’t match client expectations. When the client gives the QA team feedback, they analyze them and bifurcate them into two categories.

  1. Bug
    B. Change Request

If bugs are reported by clients, our developers instantly resolve them. Moreover, if it is a change request, our developers perform the changes in the mobile application and deliver the application to the client based on their requirements. These issues are fixed within the deadline as per the discussion with the client and project manager.

To keep a record of the feedback received from the client, our QA team maintains a sheet that has several categories defined in it. So, it becomes easier to track the changes and feedback given by the client.

  • Bug
  • Not a bug
  • Feature enhancement
  • Change request of a new feature
  • Change request of enhancement


Final Phase of Mobile Testing

The final stage of testing is similar for both Android and iOS apps. After solving all the errors received from the clients, our QA team starts the system testing.

It is performed as manual testing because it includes various types of tests from scratch to end and here are a few of them:

  • Usability Testing
  • Reliability Testing
  • Sanity Testing
  • GUI Testing
  • Functionality Testing
  • Performance Testing
  • Load Testing
  • Interoperability Testing
  • Regression Testing
  • Recovery Testing
  • Device Compatibility Testing

When a mobile application passes all the testing, then it is released on the respective mobile app stores like Google Play Store or Apple App Store.

Executing the system testing reduces the chances of rejection of a mobile application from the app stores. It helps to deliver the product to the client on time with standard quality.

As we have discussed the process of mobile testing, now let’s check out the best mobile app testing tools.
