Mobile App Performance Testing: A Detailed Guide

If you are a Quality Analyst (QA), you want to know how the App works before it goes live in the market. Hence, you may be worried that the App will not handle the vast number of users, cope with large volumes of data, or it will perform well under some critical conditions.

However, the user wants to avoid the poor usability of mobile app development. Users are also not ready to compromise the performance of mobile apps. This article will discuss the strategy for testing the app development process.

Global Consumer Spends on Mobile Apps

In the recent quarter, the total value of the global consumer spending on mobile applications is expected to be 68.7 billion U.S. dollars, a decrease of 2% compared to the previous quarter, 2021. However, between 2019 and 2021, the user’s time spent on mobile apps has experienced a constant increase, rising to 170 billion U.S. dollars during 2021. Hence, in 20222, customer spending on mobile apps was approximately 167 billion U.S. dollars.

What is Mobile App Performance Testing?

Mobile app testing is executed in the simulated environment to predict the user’s experience after deploying the application. It will aid you in ensuring that your App will generally perform between a range of devices, even if there are peak traffic loads and poor internet connectivity. However, mobile app performance is usually measured in three distinct categories.

Pillars of Mobile App Performance

The mobile app performance has three pillars for testing the App.

1. Device Performance

In this, you will check whether the App is slow or not is done to perform the device test. In the device performance testing, you have to check some elements like App startup time, Battery time while utilizing the App, Memory consumption, variation in hardware or software, and its usage with other apps.

2. Server or API Performance

It will check whether response time increases or decreases when the App interacts with an API server. In this, the server performance will review the data to and from the server, API calls generated from the App, and server downtime.

3. Network Performance

Carry out the test on the various networks to find the network performance of the mobile App.

For the network performance, check Jitters, Network speed, and Packet loss in the development.

What are the advantages of Mobile App Testing?

1. Ensure the Proper functioning of the App

The primary target of the QA procedure is to make sure that the solution is performing seamlessly. However, the QA engineers will test whether the users can successfully download the program to many gadgets. It uses real devices to test an app that comes up with a correct functioning product or service.

2. Predicts User’s Experience

Here, the experts will put themselves in the place of end users and identify the application’s look and feel. They utilize an app to examine whether its navigation is in-built and logical. In addition, it will check whether the usage of apps is convenient for the app users in varied situations. In this manner, it predicts whether a consumer will prefer using that App or will uninstall it from the mobile.

3. Increase Customer Loyalty

Customer satisfaction will rise if you ensure an application’s easy usability and accurate functioning. In this manner, the analytics will help you reach a broader audience and have a good reputation for the industry.

4. Promises Higher Revenue

The testing procedure demands an initial investment, but it helps you ignore the fixed issues and will rebuild the product at the last stage. It will save time, reduce the total cost, and permit rapid time-to-market. In this way, it cooperates with the testing expertise, and you might get high reviews in the future.

5. Reduce Testing Time in the Development Phase

Manual tests demand much time and effort. The QA becomes capable of running multiple tests in a short period. The significant advantage of automation testing is that it improvise testing speed and efficiency.

6. Cost-effective app development

Automated app testing is used efficiently, lowering your project’s cost. However, thorough testing is the primary reason behind cost savings, which reduces the emergence of bugs found after deployment. 

Therefore, launching the App n the market has defective functionalities that might lead to negative user reviews and a wrong impression of your brand. So, you must remember to test your App thoroughly from the initial stages of app development.

How Many Types of Mobile Apps Are Required to Test?

1. Native Apps

These apps are specially created for the mobile platform, iOS or Android, and are usually downloaded and installed through the Google Play Store or Apple App Store. It has native apps which the Objectiove-C/Swift builds for iOS or Java/Kotluin for Android. It also has cross-platform native apps created with frameworks like Flutter, NativeScript, and React Native.

2. Hybrid Apps

You must test your App for its expected functionality, consistency, usability, and performance before launching it in the market. Let’s see the below types of testing: 

1. Manual Testing 

Testing the software manually without using automation tools is called manual testing. The principal target is identifying bugs or defects and making the app error-free.

However, developers usually choose this type of testing approach to test particular features initially in the application development process.

Types of Manual Testing

1. White Box Testing

The developers do this testing to check each line of code before it goes to the QA team. As developers view the code during the testing phase, and that’s why it is called white box testing.

2. Black Box Testing

The QA will check in this testing that an app or software performs as per the customer’s needs. As this code is not visible while conducting the testing and due to this, it is referred to as black box testing.

3. Gray Box Testing

A combination of white and Black box testing is known as Gray testing. This testing is done by a person who knows coding and testing. Hence, there is an opportunity that gives the product high-quality features.

2. Automated Testing

2. Smoke Testing

Ensures software application stability which is internally error-free. After creating an app release, QAs perform the smoke testing.

3. Regression Testing

It ensures that an existing function will remain unaffected rather than the codebase changes and does not trigger any instability. It re-runs the test successfully in the App’s older version. It will guarantee that the new code has not recreated the old errors. As regression testing is conducted repeatedly, they are perfect for automation.

4. Sanity testing

It is typically performed after smoke testing, and this testing verifies all chief App’s functionalities that are working correctly, individually and with other elements.

5. Beta Testing

In the production environment, consumers will test the product in this phase. It will verify that how is the user interface and will assist you in further code improvements. It also identifies response speed, working in multi-tasking mode, Logic, layout, text clarity, ad size, and the look of buttons and icons.

6. Integration testing

Ensures individual models perform as expected when running in the combination.

5. Security testing

Testing unveils the application’s threats, vulnerabilities, and risks and will prevent the intruder’s malicious attacks.

The objective is to point out a software system’s possible weaknesses and loopholes that might lead to revenue loss, data, etc. Security testing identifies cookies, protection against attacks, file caching, login, and password encryption systems.

Types of Security Testing
