Continuous Testing: Integrating Testing Throughout the Software Development Process

Published On: April 28, 2023

The goal of continuous testing is to improve deployment management throughput by integrating automated feedback at several points in the SDLC. By enhancing code quality, preventing expensive bottlenecks, and speeding up DevOps operations, continuous testing is a huge factor behind the success of CI/CD (continuous integration/continuous delivery) methods that helps shorten SDLC deadlines.

A practical DevOps methodology should aim to close the gap between fast software deployment and high-quality user experiences. However, the traditional approach of manually acquiring feedback at each software development phase (i.e., project design, programming, running tests, deployment, and maintenance) has led to inadequate and inefficient use of organizational resources, and thus, relatively long integration cycles and interrupted product updates.

Continuous Testing

Continuous testing helps DevOps teams “shift left” by automating manual testing procedures and decreasing human error, hence mitigating these inefficiencies.

Automated tools load predefined QA scripts at any point in the production process, allowing for continuous testing. These scripts systematically verify source code efficiencies and ensure any pertinent input is quickly sent to the appropriate teams, all without the need for regular human participation while running QA tests.

When automated tests fail, the responsible team is alerted at the appropriate stage of development so that they can fix the code “before” it affects other teams working on various parts of the software development life cycle. A sustainable delivery model that optimizes productivity and promotes interdepartmental collaboration is possible when automated tests are performed and passed upon project completion.

Strategies of Continuous Testing

To guarantee system dependability, security, operational performance, and usability, continuous testing encompasses a wide range of tests. The following are examples of spectrum tests:

Shift-left testing

The term “shift-left testing” refers to a methodology that emphasizes testing at the beginning of the software development life cycle (SDLC) with the hopes of minimizing or eliminating costly bugs later on.

Shift-Right testing is an approach that emphasizes testing towards the tail end of the software development life cycle (SDLC), with the goal of enhancing the user experience, overall performance, fault tolerance, and functionality of the product.

Smoke tests

Smoke tests are an initial, quick check for obvious problems in software; they can be performed manually or automatically. Smoke tests are not particularly complex, but they do help find and fix the most obvious bugs in software quickly and cheaply.

Unit tests

Unit tests are great for checking for regressions across builds in the form of stress, load, volume, or memory leaks at a small scale.

Integration Testing

Testing strategies like integration and messaging look for flaws in how different parts of a program interact with one another. Teams can evaluate the functionality of end-to-end processes and scenarios by using the virtualization capabilities made possible by continuous testing. The resulting composite code is compiled and runs at runtime to ensure it behaves as expected.

Performance Testing

Evaluating the performance of application software in isolation may not replicate the conditions of the final production system, such as the hardware and middleware. To accurately evaluate the solution’s overall effectiveness, integrated system testing is essential.

Functional Testing

The goals of functional testing are to ensure that the software operates as intended in terms of the user experience and the flow of business processes. One function of good supply chain management software is to notify shipping vehicles when the product is ready to be loaded. (In contrast, non-functional testing evaluates how prepared the program is to provide the expected user experience by measuring metrics like performance, usability, dependability, response time, load time, scalability, etc.)

Regression Testing

The purpose of regression testing is to ensure that the system continues to function as expected after mistakes have been fixed in any dependent software.

User-acceptance testing

User-acceptance testing, also known as application testing or end-user testing, is when a fraction of the app’s target audience uses the software in a realistic setting. User acceptability testing might be likened to a product’s beta phase.

System Frameworks For Continuous Testing

For test suites to be consistent across modules in an application, their connectors (or APIs and containers), platforms, infrastructure, and the scenarios that describe their needs, a continuous testing framework is required.

There are two possible orders for the testing suites: sequential (e.g., regression tests come after unit tests) and concurrent

  • A continuous testing framework encapsulates the suite of tests to ensure they are consistently applied and pave the route for eventual automation. It’s important for developers to make sure that the method they use for one module is consistent with the methods used for other, similar modules. Many tests for associated software also change as the modules develop.
  • Testing scripts and functions can be easily customized with the help of frameworks. Gains from automation will materialize if discrepancies in testing are eliminated, without which the automation will produce a string of false positives.

The Importance of Continuous Testing

There are numerous gains for developing businesses that adopt continuous testing as part of their DevOps practices.

Improved productivity and enhanced reliability in deployments

At each phase of the software development life cycle, continuous testing automates the management of quality assurance and quality interoperation between processes (SDLC).

Developers can gain the actionable knowledge they need to enhance the code’s compatibility and performance before it’s deployed by adding continuous feedback loops into user and unit testing modules. Its effectiveness helps link various parts of the DevOps team and speeds up product releases.

Finding and fixing mistakes quickly across distributed projects

Modern software designs have many moving parts and layers. By using a scalable, automated testing solution, development teams are able to simplify these complexities and shorten the time it takes to find and fix bugs.

Improved User Satisfaction

Modern continuous testing techniques allow us to replicate and analyze user reactions to a wide range of use cases and troubleshooting scenarios. By running these simulations beforehand, designers may fix any usability issues with the product’s interface before it goes live and spare customers any unpleasant surprises.

Minimal cost

Particularly in big networked systems, an error in even a single application module can have far-reaching consequences, including unscheduled downtime that has an adverse effect on production and profitability.

As an example, cloud service providers frequently claim that localized failures can bring down an entire area and generate outages that can linger for hours. Organizations that rely on consistently reliable service availability may be hit particularly hard. Grain-level continuous testing finds flaws in massive software systems that would otherwise go undetected, saving money and reducing downtime.

The Significance of Continuous Testing In DevOps

Together, continuous integration and testing are used in a DevOps setting to check all newly added code and ensure quality throughout the software development life cycle (SDLC).

Each time new code is added to an application, the preloaded testing scripts will run to ensure everything still works as expected. Integration testing is often performed first, followed by system testing, regression testing, and finally user acceptance testing.

Each application module’s data feed is generated and inspected in the tests to make sure the updated code doesn’t break anything. When tests fail, the code is sent back to the developers to be fixed, after which it is reintegrated and the testing process begins again.

After successful completion of testing, the software development life cycle (SDLC) normally advances to the next phase, continuous delivery.

Continuous Testing And Virtualization

Due to the following features, IT systems and applications are more prone to mistakes:

  • Cloud computing, the Internet of Things (IoT), software-defined networking, and augmented reality are just some of the new technologies that are being combined with them (AR)
  • They are spread out in many different areas, with no gaps between the central and peripheral parts of the network. Such an architecture is useful for applications like “smart cities,” “autonomous vehicles,” and “smart utilities.”
  • Due to the lack of a centralized development environment, continuous testing becomes more labor-intensive in these scenarios. Some of the system’s components could be supplied by other parties, such as distributed teams. APIs can be used to connect the system with other programs (APIs).
  • Each development team uses a unique set of information technology (IT) tools, some of which are outdated. It is impractical to conduct continuous testing since it would require recreating the unique physical conditions of each team.

The good news is that the entire system may be replicated virtually in a single interface via virtualization, making continuous testing a viable option. Changing the configuration of a virtual machine to test for a new IT system or an updated one that fixes bugs is quick and simple.


Quality assurance would not be complete without software testing. It helps businesses save money, time, and energy while ensuring a high-quality final product. The productivity and efficacy of any software application can be greatly improved by the use of test automation.

DevOps relies on a pipeline of processes that includes continuous integration and deployment, one of which is continuous testing. Code in the CI/CD pipeline is continuously tested, integrated, and released with the help of continuous testing. By allowing teams to investigate crucial issues early on in the development process, continuous testing can reduce the likelihood of bugs and the associated costs for businesses.
