Top 10 Mobile Testing Trends to Look out for in 2021

Mobile Testing Trends

Trying to find out the top 10 mobile testing trends in 2021?

Mobile is one of the leading markets in software development. Everyone has a smartphone – an estimated 3.5 billion people.

The demand for mobile apps, games, and software is leading to another issue: rapid development.

Developers must be able to patch bugs and push new releases rapidly.

Rapid development can lead to bugs and instability, so testing needs to be initiated from the very start of the development cycle. You need to rely on automation and processes to make sure that your mobile software runs as smoothly as possible when releases are pushed in record time.

It’s important to stay on top of mobile testing trends so that you can provide the best software for your customers and/or audience.

As 2021 rolls in, you’re going to see some trends from 2020 still realizing their potential, especially automation. Let’s take a look at the trends that we project will rise alongside our usability testing services.

Top 10 Mobility Testing Trends in 2021

The following are the key trends in mobile testing for 2021 that are changing the face of Mobile Testing.

#1. Artificial Intelligence

Artificial Intelligence Machine Learning

Artificial intelligence (AI) is the next step forward for virtually every aspect of the development cycle. When something can be automated with the same quality as a manual test, it should be automated.

AI is expected to grow for the foreseeable future.

Using both AI and machine learning will help stabilize rapid releases and will also help with everything, from improving testing strategies to catching bugs. Reporting and analytics can also help.

Through AI and machine learning developers can determine:

  • Which tests require prioritization
  • Optimization of test coverage
  • Redundancies in current tests

When enough data is collected, machine learning turns even more powerful because it can help you find issues and areas in testing that you would overlook otherwise. The intelligence of machine learning, big data, and artificial intelligence will allow for forecasting, predictive analytics, and explore deeper into applications that manual testing misses.

#2. Quality Assurance Automation

Quality Assurance

Consumers want quality. In a world where there are new apps hitting the market daily, there needs to be an increasing focus on quality assurance (QA). Automating the QA process is a major part of development, but there is always going to be some form of manual QA too.

According to one survey, around 12% of companies have fully automated their quality assurance.

Some 35% of respondents said that they’re at least half-way to automating all of their QA. It’s important to be able to compete with these companies. An agile approach allows for bugs and defects to be corrected rapidly.

These quick, agile approaches take some of the work out of the QA process, too.

QA requires multiple forms of testing to truly be efficient and effective. There needs to be:

When all of the right practices are in place, it’s possible to start automating more of the QA process. Manual testing, when they’re still in place, can focus on the most integral functions and features of the apps.

If testing is streamlined, the apps run smoothly and users will become happy. 

#3. Security Testing Will Grow Increasingly Important

Security Testing

Mobile apps have grown at a massive rate, yet a lot of companies failed to focus on security.

Financial apps, for example, must be as secure as possible compared to a gaming app that survives on microtransactions.

Data flow is rising to its highest rates, and leaks can cost a developer millions of dollars.

Security is always going to be a very important part of development, but there needs to be even more focus on it in the future. When you have more than 80 percent of stakeholders agreeing that security needs to be prioritized, it’s time for your team to make it a priority.

A few of the practices that need to be put in place are:

  • Penetration testing ensures that all apps are hardened and allow you to find vulnerabilities that can lead to data breaches
  • Cybersecurity testing to ensure that systems and internal servers are properly secured

Multiple forms of testing may be employed with security testing, from robust penetration to scriptless test automation.

When you focus on security testing this year, it will allow you to create apps that maintain a high level of user data with less risk of data leaks.

#4. Scriptless Test Automation

Scriptless Test Automationn

Scriptless automation frameworks will continue to rise in popularity in 2021 as more companies look to leverage their resources more effectively. There’s no need for coding or scripting knowledge to produce these tests, so they can be pushed off to non-senior developers to free up high-end resources.

Frameworks and customization will reign supreme because a one-size-fits-all approach will not be viable for most mobile apps.

What does this mean?

A lot of the code will be provided via the framework, but to achieve higher levels of customization, we need to have some custom coding in place. Scriptless testing will remain only one part of the testing cycle and will need to be used alongside:

  • Manual coded or scripted tests
  • Automated and AI testing

While there are a lot of scriptless test automation tools being developed, some of the most common include:

  • TestCraft
  • Kobiton
  • Zap Test

Cloud-based testing allows for many of these scriptless testing options to be run without additional hardware. With a SaaS solution, it’s possible to implement scriptless testing rapidly into any mobile development environment.

#5. API and Service Testing

API Testing

A lot of mobile apps and development are derived from full-scale non-mobile environments. For example, a lot of SaaS companies are building out websites with top-end features because they cater to PC users.

These sites have the logic and functionality in place to be used through an API to rapidly develop mobile apps.

API and service testing will be on the rise this coming year due to the high development on the Client-Server side of things. APIs can quickly cut down on coding requirements and allow for apps to be rapidly deployed.

APIs will need to be hardened, and this functionality will need increasing testing to ensure top-end security with as few bugs as possible. Test automation will be put in place to help make API more efficient and robust.

Test teams will have to focus heavily on the communication between apps and the API. Of course, independent testing will also be required even when API is in high use because UI, features, and functions will still have to exist in the app that isn’t provided through the API.

#6. Outsourcing to Usability and Quality Testing Centers


A lot more companies will be outsourcing their quality assurance and usability testing needs. There’s no need to do everything in-house, and these centers offer a lot of perks that only dedicated teams could offer:

  • Teams can be deployed to focus on your product’s usability and quality
  • Outsourcing to companies allows for easy scaling and access to the latest tools and practices
  • More time can be spent on the actual development of your product

Outsourcing is safer in the usability and QA phases because there’s no need to share source code. These entities won’t have access to proprietary algorithms or IP that can be mishandled or sold to competitors.

We expect a lot of companies to put their trust in third-party testing companies because it lightens the burden on internal teams and ensures that quality and usability are maintained.

#7. Continuous Integration and Continuous Delivery Will Continue to Grow


Rapid development remains the cornerstone of the mobile industry. Developers are working night and day to find bugs, respond to tickets, and fix bugs. Entire teams are working together to get new patches and versions to app stores.

Continuous integration (CI) and continuous delivery (CD) are two of the most integral parts of large-scale app development.

Using automated tests, CI and CD are able to fit into each stage of the development cycle. Bugs are able to be found and corrected almost instantly as the automated tests work in the background.

Since code is added to a shared repository often, automated tools and builds are used to verify the code and its stability. Problems can be detected early on in the process so that they can be rectified as quickly as possible.

Keep in mind that CI and CD are about creating a culture where it’s possible to deliver changes to code faster and more reliably. Mobile demands fast releases and CI and CD can be the backbone of these releases.

#8. DevOps and Agile Testing

Agile DevOps

DevOps and Agile approaches are already well-integrated into a lot of the development lifecycle and environment already, but we’re expecting an even deeper integration of the two. Testers and developers are going to have closer working relationships, with QA testers expected to acquire even more coding skills this year.

The new coding skills will help QA testers and developers collaborate on projects with a higher appreciation and less friction.

Since the time to market is expected to remain short – maybe becoming even shorter – it will be vital for agile testing and DevOps to work closer together. But this doesn’t mean that QA is going to take over the job of a developer. Instead, we’re simply going to see the two working together in an even greater capacity.

#9. Real Device Cloud Testing

Cloud Testing

Annually, over 1 billion smartphones are sold. The market is massive, and these devices will pose their own issues for developers. A lot of users will be running devices, such as the iPhone and Pixel, but there are a lot of foreign phones that are sold, mostly at cheaper prices, that are running older versions of Android.

Testing teams cannot test every single device, keep them charged, and run through a battery of tests for each smartphone. But there’s another way that will allow you to test your real devices on the cloud.

When you use real device cloud testing, you’ll be able to:

  • Tests dozens of different devices
  • Scale up or down using the cloud

You can have your team test their apps on devices and operating systems around the world. Real device cloud testing allows for mobile apps that are more robust and don’t have the same high level of bugs that other apps have.

When it comes to quality assurance, testing on the cloud using real devices allows for:

  • Differences in performance across different devices and operating systems
  • Learning key issues that can impact the app or user experience
  • Network failure identification and other issues

Manual and automated testing can be done using this approach. When automated testing is in place, it’s possible to conduct large-scale testing that’s not possible with a room full of devices.

#10. IoT Testing Focus

IoT Devices

If your app isn’t going to be a part of the Internet of Things (IoT), you can skip this section because it doesn’t pertain to you. But since wearables are becoming growingly popular, there are going to be more apps that connect and interact with them.

IoT devices are connecting to smartphones, causing a new variable to be added to the testing process.

Testing will need to be more complex when IoT connects to your app, including:

  • Data security testing and sanitization
  • Protocol and procedures for data transfer and operation
  • Power consumption concerns
  • Issues with connection and communication failure

If your app will use IoT communication alongside AI, AR, or VR, it’s important for QA engineers to use real devices and cloud approaches. For every new wearable, it’s possible that some functionality will cease working in the app or may not act as expected.

Diversity is a growing problem because there are just so many devices and differences to consider.

Your team will want to sit down and determine which IoT device that the app should work with. Cloud testing solutions enable you to test the app on new devices and currently supported devices in a way that owning physical devices would make it difficult to do.
