In the last few years, the state of the art of Software Testing and Quality Assurance has significantly evolved.

Cloud computing, Big Data, emerging technologies such as Blockchain, and the pressing need to focus on cybersecurity, have impacted considerably how Software Testing will be planned and executed in 2023. 

This article will focus on six trends that will shape how Software Testing will look in the upcoming year.

Artificial Intelligence, Machine Learning, and Big Data

Artificial Intelligence (AI) and Machine learning (ML) are among the leading change agents of the future. Applying AI and ML techniques to software testing is not new.

Still, recent developments in these areas, together with the vast amount of data available in the cloud (enabling Big Data testing solutions), present a unique scenario for AI and ML software testing approaches in 2023.

AI and ML predictive models will help companies make better decisions about what regions of their software platforms to test. Smart analytics and observability support development teams in detecting errors, identifying areas of high risk, and designing proper mitigation plans.

By using Machine Learning techniques, software development teams can also have AI systems to look for specific code checks in the development phase.

These tools can perform anti-patterns detection and best-practices suggestions based on trained models. 

ML-based tools can perform Log and Defect analytics to identity checks that should be done automatically and rank and evaluate regression tests unattended.

Notably, when using AI or ML testing approaches, the prediction of critical test configurations can be based on previous checks. 

In 2022, companies will increase their use of AI and ML in software testing, from user interface visual testing to self-healing mechanisms for cloud-based platforms. 

Internet of Things (IoT) Testing

Internet of Things (IoT) devices are usually small hardware devices that are digitally interconnected and streamline data flows over the network.

According to this Gartner forecast, active IoT devices will reach 21.5 billion units by 2025. With this expansion rate, software testing teams will focus on functional tests and IoT devices' firmware performance and security.

Critical aspects of testing on IoT devices include dealing with connection delays, data corruption, encryption, and distributed scalability. IoT testing teams will face plenty of challenges in 2023.

As more companies develop IoT solutions, software testers will have to apply traditional and new testing approaches to ensure final IoT products' software, hardware, and firmware quality. 

Scriptless Test Automation

Test automation has been around for quite a few years. However, as more companies adopt DevOps and Agile practices, testing automation becomes essential.

Automation plays a vital role in Agile practices, Continuous Integration & Delivery, and DevOps. As this trend progresses, the need for teams to automate their testing processes will significantly grow.

A robust approach in this area is Scriptless Test Automation.

With scriptless or codeless testing automation, testing teams can build and maintain automated tests without having strong coding skills.

Some codeless testing tools leverage AI and ML algorithms to enable testers to improve and reuse test suites.

Tools like Katalon and Perfecto Scriptless, to name a few, allow codeless test building for beginner testers and build scalable and extensible testing suites for advanced users.

Scriptless testing tools are usually user-friendly and help reduce the time and effort spent on maintenance. They can also help fill some skill gaps between developers and testing teams. 

Agile, DevOps and QAOps

Companies worldwide are adopting Agile and DevOps. Agile Methodologies help teams quickly adapt to changing requirements, and DevOps helps companies deliver quality software products with high throughput.

In the Agile approach, testing is no longer a phase done after development. Agile Software Testing happens in each iteration, alongside Software Development.

Moreover, as the Microservices architecture pattern continues to be widely implemented, Software Testers are often distributed across different development teams instead of being grouped in a Testing or QA department.

This pattern calls for testing teams to significantly improve their communication and collaboration skills and adaptability to constant change.

As DevOps is a combination of software development (Dev) and IT Operations (Ops), the term QAOps refers to the same phenomenon for Quality Assurance (QA) specialists. 

QAOps combines QA with the main ideas of DevOps, which are Continuous Integration (CI), and Continuous Delivery (CD). With this approach, Continuous Testing (CT) happens in the same software development pipeline. 

The QAOps practice implies three development pipeline actions: Trigger, Execute, and Report. Tests are built on the trigger phase, parallelly run on the execution phase, and a briefing of execution is produced on the report phase.

QAOps enables another Agile-fueled testing trend: Shift-left QA ("left" meaning "earlier" by convention when project phases are visualized in a workflow). In the "Shift Left" approach, teams strive to conduct tests as early as possible in the development pipeline.

With Shift-left, software development teams focus on collaboration and proactivity to ensure the feasibility of requirements upfront. This approach allows the Testing team to work side-by-side with Developers and Product Owners right from the beginning of a project.

The key to "shifting left" is to measure the effectiveness and correctness as soon as possible. The idea behind shifting left is simple: testing in the early stages helps save time and money.

As it happened with DevOps, QAOps and the Shift-left approach are exciting trends to look for in 2023.

API and Services Test Automation

Client and Server decoupling is an extended practice in current software architectures. Application Program Interfaces (APIs) are intensively reused in distributed microservices platforms.

These architectural patterns require QA and Testing Teams to test API and services independently from the clients consuming them. 

Given the increasing number of APIs used in distributed software, there is a pressing need for automated API testing. 

One of the most popular tools for API testing is Postman. With tools like Postman, teams can automate different API tests, including unit, functional, and integration tests.

Automated API testing tools allow integration with CI/CD pipelines, leveraging built test suits with every code change.

By adopting automated API tests, companies can save money on QA and lower communication lag between QAs and Developers. 

Performance, security, and Blockchain testing

Last but not least, in 2023, the industry will see an increase in what could be called non-traditional testing. Testing teams will have to up their game in testing non-functional attributes of software products such as Performance, Scalability, and Security. 

In particular, the growth Blockchain and other distributed ledger technologies have experienced in 2020 and 2021 will continue to speed up in 2023 exponentially.

Blockchain is considered one of the most advanced emerging technologies currently in the market. This technology has a strong probability of dramatically impacting distributed data, cryptography, and even currencies in the near future.

As more companies begin to develop blockchain-based software products, testing teams will have to add tools and practices to help development teams verify the correctness of their work.

As with any emerging technology, there are new risks to mitigate. Data security issues call for new effective distributed ledger testing strategies. This is an unsolved challenge that testing teams will face in 2023.

Security testing has become a pressing issue for organizations worldwide. Having employees, contractors, and partners with the right security expertise is critical to any organizations' well-being.

Testing teams increasingly have to deal with confidentiality, authentication & authorization, integrity, and other security requirements. There will be an increased demand for these testing skills in the following years. 


This article has covered six software testing trends that will significantly impact companies worldwide in 2023. To summarize:

  • Artificial Intelligence, Machine Learning, and Big Data. New tools enable software testing teams to detect and correct defects automatically. Predictive models can be used to improve test suites efficiency. Tools that leverage ML and AI algorithms can help Testers see common anti-patterns and apply best practices without much effort. By having AI systems analyze execution logs and track defects, some improvements can now happen in an unattended way.

  • Internet of Things (IoT) Testing. As millions of new small hardware devices connect to the Internet, there is a pressing need for companies to assess the quality of the firmware these devices run. IoT imposes on testing teams the need to test for encryption issues, data corruption, and connection problems, among others. 

  • Scriptless Test Automation. Codeless testing tools help testing teams to focus on functional aspects of testing without the need for high-level coding skills. These tools also use AI and ML solutions to automate testing tasks. They aim to be user-friendly for both technical and non-technical users.

  • QAOps and the "Shift-left" approach. As it happened with Development and IT Operations merging into the new DevOps approach, QAOps does the same for Testing and QA specialists. Companies can save time and money preventing software defects by integrating testing into the development pipeline and shifting testing activities as much to the left (earlier) as possible.

  • APIs and Services Test Automation. Having distributed APIs and Microservices is a typical architectural pattern nowadays. This requires QA teams to test APIs regardless of the client consuming them. As the number of APIs significantly increases, there is a need for automated tools to help testing teams on this task. Automated API Testing tools enable teams to integrate this type of testing into the CI/CD pipeline, improving communication between them and other Developers.

  • Performance, security, and Blockchain testing. Cybersecurity has become a top priority for companies worldwide, and distributed ledger technologies continue to be widely implemented. Testing teams in 2023 will need to add tools for testing security and encryption in general and in Blockchain and other distributed ledger technologies in particular. Performance testing and other non-functional testing skills will be in great demand soon. 

As the year 2023 unfolds, these and other trends will press on software development and testing teams to improve their skills to help companies protect their value propositions and meet the increasing demands for excellent quality software products.
