With the increasing pace of the development cycle for software, it will be more important than ever that the quality of applications is maintained in addition to just “working” for some period of time (e.g., producing output). This is where a BDD (Behavior Driven Development) framework for Selenium can shine, and it does. The BDD approach helps bridge the gap between both technical and non-technical teams, enabling team members at all levels to understand and review test scenarios, without having to constantly interpret for each other (i.e., translating back and forth) what the tests are doing.
Building a new automated test framework or modifying an existing one with the use of a BDD framework in Selenium will result in improved collaboration among testing team members (technical and non-technical), expanding the coverage of your automated test suite, and providing for better overall software quality. Here are five primary reasons that organizations are moving to this style of testing in their Selenium test automation.
Improve Collaboration Between Team Members
An obvious benefit of using a BDD framework with Selenium is to provide a better opportunity for developers, testers, business analysts, and project stakeholders to communicate and align with one another.
BDD uses a simple, human-readable format called Gherkin that describes test cases using “given,” “when,” and “then” keywords; this means that every person involved in developing the software has a common understanding of requirements and expected outcomes before any development occurs.
Having everyone speak the same language helps to eliminate confusion. It helps ensure the completed application will meet the expectations of the business as originally envisioned (not how we thought it should be).
Easier Readability & Maintenance of Test Cases
As a project evolves, maintaining a set of scripts that automate testing can be difficult to manage; BDD frameworks make it easier because business logic is separated from the automation code.
You describe what the application will be able to do in feature files using everyday spoken language, while the step definitions contain the actual Selenium commands that will execute the tests. As a result of this separation, the test cases are much easier to refresh if requirements change or if a stakeholder decides he/she wants to make a small edit at the last minute.
Thus, teams will spend less time on script maintenance and have more time available to implement new features.
Promotes Reusable Testing Components
Reusable testing components are advantageous. The use of a BDD framework with Selenium allows for reusability!
If a step definition has already been created, it can also be reused in other feature files without having to recreate the same automation code again and again. This eliminates duplication, makes maintaining the framework less of a burden, and increases overall development productivity.
For larger automated testing projects with hundreds of test cases, the use of reusable components promotes common test patterns, but it will also contribute toward decreasing total execution effort versus creating each component individually; this is a subtle, yet significant, advantage.
Agile and Continuous Testing Support
Agile development combined with DevOps allows most software organizations to produce software on an earlier schedule than previously possible. By utilizing a BDD (Behavior Driven Development) testing methodology alongside traditional automation testing tools such as Selenium, Agile teams will be able to accomplish this because of the constant collaboration among team members as well as the integration of automated testing across all stages of the build process, rather than just during the last stage of the build process.
Automated testing scenarios designed based on BDD principles can easily integrate into CI/CD (Continuous Integration / Continuous Delivery) tools such as Jenkins, GitHub Actions, and Azure DevOps. Therefore, every time code is modified or built, one can execute their automated Selenium tests so that teams can identify defects before they reach production, thus allowing them to release higher quality products quickly as well. The continuous feedback loop created by automated testing will reduce the number of defects that go to production and increase release frequency at the same time.
Enhancing Software Quality with Test Coverage
The principal goal of any automation strategy is to create software that users can trust. A BDD framework, utilized with Selenium (an automation tool), can be of great assistance to a team in accomplishing this goal in that it compels them to think through what they want their application to do, prior to executing any coding to automate it.
By providing the ability to execute scenarios against the requirements defined for a project, the likelihood that business processes will get overlooked during the development phase is significantly reduced. This also allows testers to develop broader test scenarios that include both positive scenarios (i.e., happy paths) and negative scenarios (i.e., all of the things that could go wrong), thereby increasing overall test coverage.
When there is good test coverage (through automated validation of business processes), there will be opportunities for businesses to identify bugs earlier, reduce the risk of regression, and therefore improve user experience.
Conclusion
The choice of a BDD framework to work with Selenium is not only a technology choice but an important decision regarding strategy and investment in collaboration, maintainability, and software quality. Clear test scenarios that you can read properly, along with reusable automated components, combined with Agile and CI/CD rhythm integration, will produce teams with frameworks that provide good scalability and that are easier to maintain.
If your company is looking to enhance communication among stakeholders and produce reliable Selenium automated tests, then implementing a BDD framework in Selenium appears to be a logical step toward quicker releases and improved overall quality of software.
