In today’s quickly changing environment of software development, the adoption of Continuous Delivery (CD) strategies has become vital for businesses that want to effectively provide high-quality software to their customers.
A solid test automation approach is an absolute must if you want to reap the benefits of continuous Delivery (CD), which include quicker release cycles and fewer manual interventions. Nevertheless, there is more to successful test automation in a CD pipeline than simply automating test cases. It entails using an approach that has been given considerable thought and is consistent with the CD principles.
This article takes a deep dive into the most important tactics and best practices for efficient test automation in an environment that uses Continuous Delivery.

Continuous Delivery, often known as CD, is a process that is integrated, organized, and automated, and it is used to rapidly incorporate code updates into production environments. However, human interaction is required in order to decide whether or not to deploy.
Benefits of Continuous Delivery
Continuous Delivery makes it possible to send software changes to the production environment in a timely and regular manner. It offers a multitude of benefits to companies, development teams, and end-users alike. The following is a list of the primary advantages that Continuous Delivery offers. Please take a look at it with me.
Faster Time to Market
Continuous Delivery drastically cuts down the amount of time needed to create new code, incorporate that code into the product, and validate that code. It might be anywhere from a few days to many weeks or even months. The CD also greatly increases the release frequency, moving away from massive yearly and semi-annual upgrades and toward daily or weekly releases of targeted fixes and improvements. This transition occurs as a direct result of the CD.
Creating the Right Product
Frequent releases with short lead periods aggregate rapid input from customers, allowing teams to evaluate whether or not brand-new features are suitable for the market. In contrast to the situation before the implementation of continuous Delivery, the months spent developing and testing a feature won’t be squandered even if it doesn’t meet the necessary criteria.
The CD is very dependent on automated deployments. Developers are freed from the responsibility of setting and maintaining the test environment as a result. As a result of the Continuous Delivery process’s increased level of automation, troubleshooting efforts are also significantly reduced. In addition to this, the CD pipeline will immediately push the newly developed software to production as soon as it is ready. This shortens the time it takes to go through the phases of development, testing, and release.
Better Customer Satisfaction
All of these advantages help to produce a product of high quality and boost the consumers’ confidence in the functionality and dependability of the program.
Because it ensures thorough and consistent testing across the development and deployment processes, test automation is an essential component of CD. It makes it possible for developers to receive rapid feedback on changes made to the code, which enables them to identify and resolve issues early on in the development cycle. Because of this, having a solid plan for test automation is essential to the accomplishment of continuous Delivery (CD) in software development.
Effective Strategies to Automate Tests in CD
Continuous Delivery (CD) that is successful is dependent on a pipeline of automated tests that functions well; nevertheless, test automation is a specialist field that stands on its own. Let’s analyze several successful approaches to test automation in CD by breaking them down as follows:
- Imagine a timeframe in which software development takes place. Now, think about shift-left testing. The testing activities should be moved earlier on this timetable, which is what “shift left” suggests. Examples of this strategy include test-driven development (also known as TDD) and behavior-driven development (also known as BDD). Before developing the actual code, developers in TDD and BDD first construct tests of the system. This compels them to consider how to test their code, which ultimately results in software that is more focused and more easily tested.
- Testing that is Driven by Behavior in Development (also known as BDD): BDD is a technique that evolved from TDD. It takes elements from TDD, domain-driven design, and object-oriented analysis and merges them into one cohesive methodology. For the purpose of describing how the program should act, BDD makes use of a particular language that is similar to natural English. It helps teams interact more successfully and is beneficial when dealing with difficult situations.
- Automated tests are typically used to check that software functions appropriately. One type of automated test is known as cross-browser testing. It is not always practical, due to time restrictions, to personally test an application on every web browser and operating system. The most well-known and widely employed web browsers and operating systems are the primary targets of practical testing. Data on usage compiled by applications such as Google Analytics can assist in determining which web browsers are utilized the most frequently.
- Tools such as Maven and Jenkins are examples of continuous build tools. These tools may be used to construct and execute the most recent test scripts against the most recent application version. Continuous testing like this guarantees that the program operates properly and helps detect problems at an earlier stage.
- Non-Functional Testing: This kind of testing focuses on elements other than functionality, such as performance and security. The difference between performance testing and security testing is that performance testing evaluates how quickly and effectively the program functions, whereas security testing looks for flaws. Although performance testing is often part of the CD pipeline, additional non-functional tests, such as security testing, can also be helpful and should not be overlooked.
- Testing in Production: This strategy entails delivering a new feature to a limited set of users (for example, 10%) and watching how they react to it. After that, a different version is made available to a different group of users, and their preferences are compared. Before a new version of a feature is made available to all of the users, this technique, which is also referred to as A/B testing or Online Controlled Experiments, helps decide which version of the product is preferable.
The way we develop and test software has changed a lot with the emergence of CI/CD. Developers need timely feedback on the quality of their software changes. Because of this, testing teams are reevaluating their procedures in an effort to increase efficiency without compromising quality.
But there’s a catch: comprehensive testing and fast testing aren’t necessarily compatible. How, then, do these groups adapt to the new circumstances? They don’t simply need improved technology; they need to modify how they think about testing. It’s not about using expensive equipment but rather adjusting their mindsets and methods while testing and collaborating.

To illustrate how HyperExecute may be utilized to accelerate a CI/CD pipeline, consider the following scenario:
A group employs a continuous integration/continuous delivery pipeline to roll out an updated version of their web application. Each commit triggers the pipeline’s battery of automated tests. They discover that it takes too long for the pipeline to finish, which slows down the rollout of new features.
Their CI/CD pipeline now includes HyperExecute. Automatically assigning test machines and dividing the tests among them is a breeze using HyperExecute. As a result, automated tests in the pipeline may be completed significantly faster. The team can now speed up the rollout of new features to production without sacrificing test coverage or rigor.
