Mobile App Testing Types

The wide range of mobile apps available in the marketplace has allowed smartphones to transcend their purely utilitarian origins. With over 4 million mobile applications accessible for download, consumers have a plethora of alternatives.

Due to these extremely competitive market forces, you should guarantee that your mobile application’s reliability, accessibility, and privacy not only match but surpass expectations.

The mobile application market is constantly expanding as a result of increased competition. Each app faces fierce competition from other apps that accomplish the same task or serve the same user demographic.

Multiple apps are available to do the same job. As a result, apps must be appropriately designed and tested in order to compete in the global market and maintain a competitive edge.

What Is Application Testing for Mobile Devices?

Performing mobile app testing is the technique of evaluating apps for smartphones. The primary objective is to evaluate the applications’ performance, applicability, and reliability.

To provide the highest possible level of quality for end customers, the app is also examined on a variety of additional factors, including UI, UX, and Security.

The Different Types Of Mobile Applications

Mobile apps are classified into three broad categories:

Types of Mobile Applications

Native Applications:

Native applications are those that are built for a particular environment or OS. Because they are OS-centric, they have the extra benefit of being quicker and more dependable in terms of reliability but are also more expensive to maintain.

Web Apps:

Web applications are identical to native applications with the primary distinction being that they may be accessed via a mobile device’s browser. It has modest development costs but is completely dependent on the smartphone’s browser.

Hybrid Applications:

Hybrid apps combine native and web based applications. They make use of a web view control to display the HTML and JavaScript scripts in full-screen mode.

While these applications are inexpensive and easy to produce, they lack the strength and performance of native apps.

There are several benefits to automated testing of a mobile application, such as reducing the amount of time and effort spent on testing and increasing the return on your investment. This requires investing in a solution that automates your mobile application.

Why Is Mobile Testing Critical For Your Application?

A mobile application development business that is not committed to quality is likely to fail, resulting in the waste of all the work and effort.

Mobile Testing Tools

The majority of negative reviews on the app stores are for malfunctions, lack of performance, or battery drain, most of which might be prevented if the application had been fully tested.

For the following reasons, mobile apps must be thoroughly tested before they are released:

Without Errors & Bugs

It is possible for an application to have bugs or faults. Such an app will undoubtedly have a detrimental effect on its intended audience. No user enjoys using an application that contains bugs since they make the in-app experience extremely frustrating and unsatisfying.

Before launching, testing significantly minimizes the likelihood of such faults and failures in the software. Consumers always prefer apps that are bug-free.


Evaluating an app enables developers to determine the app’s performance. If the performance is still not adequate, developers can make adjustments to the software.

User Opinions

Nowadays, mobile app testing also includes providing select users with access to the app before its formal debut. This enables developers to collect reviews about their products from actual users.

These critiques are extremely beneficial to developers since they operate as feedback from the general public. The designers can make modifications to the in-app interface depending on user feedback.

Check for Security

When a user’s personal data is stored on a smartphone, it must be protected against hackers and snoopers. Testing serves as an extra layer of defense against assaults by malware or unauthorized users. This assures the application’s safety throughout the operation.

Increased Revenues

There is an initial investment, but it is necessary if you want to reap greater rewards in the long run from mobile testing.

Today, even small businesses may afford to do testing through collaboration with assessment service providers, which is typically less expensive than hiring a full-time tester.

Compatibility Between Diverse Networks

Users’ mobile phones do not share the same network. Due to the presence of many networks, the app must be interoperable with all of them.

Testing enables coders to interact with the application on a variety of different connections and ensure that it works on the majority of them.

Compatible with a variety of Mobile Devices

There are several types of mobile gadgets in use today. Every one of them is unique, and some of them fall into more than one category.

As a result, it is critical to test the app on a variety of mobile devices to guarantee that it functions properly on the majority of them. This ensures compatibility and, as a result, expands the user base.

The Different Types of Mobile Application Testing

1. Functional Testing

Functional testing determines whether or not the features meet the criteria. For instance, it validates user activities with the application, such as starting it, signing in, playing music, and examining account balance, among other common user flows.

As functional testing communicates with the user interface parts of the application, the database layer, the network layer, and much more, it is a time-consuming and sophisticated procedure in general. In order to get the most out of this, you’ll need to balance out the various functional testing methods.

Mobile Application Testing

2. Regression Testing

As the name implies, regression testing verifies that new feature updates, fixes, or system updates did not result in the introduction of new regressions, or vulnerabilities. Regression testing verifies that any modifications made by the developmental process actually result in an enhancement.

For instance, with each software upgrade, numerous SaaS companies may improve existing features or add new capabilities to their offers. These businesses will do regression testing to guarantee their core product is not impacted by new feature additions.

3. Performance Testing

Performance testing is the practice of assessing how a system performs under a certain workload or a specific job. Performance testing examines a program’s responsiveness, dependability, and scalability. It occurs on both the server and client sides.

On the server side, it monitors responsiveness, resource-intensive packet buffering, communication delivery delays, and application failures, among other things.

Types of Performance Testing

On the client side, it verifies the common inconsistencies in implementation details across platforms and phones, memory and CPU use, startup speed, and battery life.

The numerous forms of performance testing are listed below:

Load Tests

The app’s performance is evaluated using the load that it is anticipated to handle on a daily basis. This signifies that the app is validated by simulating the predicted user population.

This entails evaluating the application in many areas in order to maximize the number of users and sessions each day. Load testing verifies that the application operates normally under such conditions.

Stress Tests

This entails stress testing the product in harsh conditions. This refers to instances where the number of users exceeds expectations. Occasionally, such stress conditions may arise during the application’s lifespan. As a result, these stress tests assist in ensuring that the application functions well in these conditions as well.

Endurance Tests

These tests are used to determine how well an application performs when subjected to an elevated workload over an extended period of time.

These ensure that even when the workload surpasses the average for an extended period of time, the app can continue to function normally.

For instance, during events or festivals, individuals engage in more talks than usual. At this point, messaging apps should not fail. This can be accomplished by conducting well-designed tolerance tests.

Volume Tests

This is accomplished by increasing the number of transactions/data that the program must handle. This enables the application to cope with instances where the amount of data/transactions is significantly greater than the average.

Spike Tests

These tests evaluate the app’s performance when the number of users suddenly increases or decreases. For instance, when college admissions results are released publicly, the app is certain to see a spike in user requests and activity. Spike testing is designed to guarantee that such occurrences are carried out properly.

4. Unit Testing

This test entails the evaluation of the software’s component units of code. A single unit is the tiniest component of code that could be tested.

These units are tested to ensure that each block or combination of units performs as intended and meets all applicable criteria. For example, in a messaging application, unit testing should be limited to the send unit.

5. Security Testing

Mobile app testing must include security testing since it might be business-critical, like in the case of hackers stealing consumer data. Security testing is a complicated subject that necessitates expertise in a variety of fields, including client-server communication, software design, and the architecture of the system.

Due to the complexity of security testing and the particular skill set necessary, it is best left to professionals. It entails human or automated vulnerability scanning using man-in-the-middle techniques, as well as heuristic analysis, analyzing, and auditing the application.

Penetration testing is a technique for identifying security flaws in a program that permits unauthorized access to its functionality and contents. Numerous open-source and commercial tools are available for testing applications for security flaws. Security testing encompasses the following parameters:

#1. Data Security:

The app should be able to safeguard data and prevent it from being accidentally exposed to other apps.

#2. Hacking:

Malicious actions are rampant in the modern-day, and hence the app must safeguard itself from such attackers. The program must be free of vulnerabilities that might be exploited by hackers.

#3. Authentication & Authorization:

To avoid malicious behavior, the application should provide adequate authentication and authorization.

6. Usability Testing

Real users evaluate the capabilities and performance of the mobile application during usability testing. The central emphasis of this testing is on the ease and speed with which an app may be used, the simplicity of enrollment, and the user’s pleasure with the whole experience.

Users are assigned tasks in a testing phase and expected to express them aloud while they attempt to complete them. They monitor a variety of user behaviors, including attitudinal, preference, and situational, in order to optimize the app’s consumer experience.

7. Recovery Testing

These tests examine the app’s recovery capabilities. This implies that the software must be able to recover data if it becomes unresponsive for any reason.

This type of failure might be caused by a software fault, a network issue, or a device issue. Such tests are intended to evaluate an application’s capacity to recover from such problems.

8. Compatibility Testing

Mobile apps must be tested for compatibility with a wide range of devices and operating systems. Compatibility testing is used to ensure that the application operates consistently across a range of gadgets.

The following procedures aid in covering the greatest possible number of devices during compatibility testing:

  1. Prepare the Device Compatibility Repository: For each device or model on the marketplace, gather the data about the platform, the technical features offered by the device, the hardware features contained in the device, and the network recognized by the device.
  2. To ensure that the device list covers the largest number of users in the region, narrow the device list according to the region’s or country’s idiosyncrasies.
  3. Split all gadgets into two categories: Those that are totally compatible and those that are only partially compatible. Perfectly compatible devices offer all technical features necessary to ensure that all application functions operate flawlessly, however partially compatible gadgets may lack one or more characteristics, resulting in error messages.

9. Localization Testing

These tests are typically conducted on apps that are targeted at a particular geographic location. These tests guarantee that the program is compatible with every element of the location to which it is aimed. Its primary objective is to convey the impression that the app was created expressly for the demands of the location.

While conducting localization tests, the following aspects must be considered:

  • The region’s currency.
  • Languages are indigenous to the area.
  • Religions and Customs.
  • Regulations by the government.
  • The region’s time zone and date formats.
  • Symbols, emblems, and other identifiers exclusive to an area.

10. End to End testing

End-to-End Testing is a mechanism for determining whether an app’s flow is working as intended from beginning to end. End-to-end testing is used to detect system dependencies and to guarantee that the correct data is sent across various system modules.

The entire program is tested in a realistic environment, including interaction with the databases, networks, infrastructure, as well as other services.

11. User Acceptance Testing (UAT)

User acceptance testing (UAT), often known as beta testing, is a process that is carried out by actual users and is frequently employed as the last checkpoint before a product’s deployment.

It enables people to evaluate your application and determine if it is user-friendly, performs as intended, and is capable of handling tasks in real-world situations (or not). Generally, project leaders, programmers, the QA team, and stakeholders are present for the final inspection during UAT.

12. Installation Testing

These tests evaluate both the deployment and deletion processes of software. These evaluate the installation process’s simplicity and effectiveness. This guarantees that all folders on the smartphone are properly installed when the setup is finished. Moreover, this guarantees that any associated files are deleted from the device upon the application’s uninstallation.

Additionally, these tests ensure that future upgrades are deployed without incident. Further, the program should be able to pause in the process of setup without impairing the device’s other functionalities.

The following parameters are used to do installation testing:

  • The directory in which the program is saved.
  • Compatibility with a variety of operating systems, gadgets, connections, and web browsers.
  • Notifying the user appropriately if memory is insufficient.
  • Keeping the app compatible with an earlier version for as long as possible.

Automated Mobile Device Testing

Mobile test automation enables the rapid and effective testing of mobile applications while increasing test coverage. After a test has been automated, it can be run at a high rate and continuously.

It is virtually always the most cost-effective solution for software products with a lengthy lifecycle of software support and maintenance. The actual value of automation is not just in terms of test repetition, but also in terms of the capacity to run tests that would be impossible to run manually.

Given that the majority of businesses adhere to agile development practices, automation testing is a suitable match for the agile process.

The ability to run tests in parallel, such as nightly sessions, is a big benefit of test automation. The tests will be completed the following morning, and the outcomes of the most recent regression will be available for evaluation.

Early resolution of an issue saves valuable time and enables engineers to complete the product more quickly and more significantly, it results in a higher-quality product with fewer flaws.


To create an app that is great in every way – from design to functionality to usability is no easy task. Numerous variations of application testing would undoubtedly be taxing.

However, by ensuring that your mobile app functions well on all frontiers, you increase your chances of consumer satisfaction.
