BDD (Business-Driven Development), an expansion of Test-Driven Development (TDD) that highlights emerging features based on a writing code and user story provides an output to actual barriers. This implies that the customer or product manager describes a concept, and the developer then interpret those practices to meet affirmed business objectives. At that point, the tester comes in to check whether this new component meets the "why" behind the code. Due to the changing mindset of testers, it requires mastering unique skills and more importantly, developing the attitude, and the method of working.
BDD, TDD, and ATDD are the major expressions which have transformed the software tester's world in agile and have gained an impulse too. Nowadays, software testing industries are rapidly moving towards Shift Left testing to modify their quality engineering efforts with the rising acceptance of BDD and Agile methodologies.
Creating tests is considered as not a good practice but is being considered as the provisions to the code. Therefore, these expressions may follow these approaches in development. And, Dan North recommended that instead of creating tests, you should think of stipulating behavior or the method, the user wants the app to perform.
This strategy changes the testers’ role substantially. At the point when generally testers look out for errors after the work is done, some or the other requirement issues gets reflected. And, this is where the BDD approach comes with a crucial phase. Software testers can practice their skills amid the early stages of the development process in order to examine the requirements.
It is maintained by building executable scenarios. In other words, the scenarios mentioned by users are transformed into executable tests. BDD frameworks adapts with it perfectly. As the entire team is generating a set of scenarios, it gives close collaboration between product proprietors, project managers, software developers, business analysts and software testers. This results in a higher level of customer satisfaction.
Let's look at these methods for BDD testers that are becoming increasingly prominent and determine how it's helping different teams drive the up-to-date software.
1. Try to Understand BDD Concept Thoroughly
BDD requires a completely different position for software testers and they should realize that as per this approach, “bug is a missing scenario”, if something doesn't get worked after execution, then it implies that you haven't built such scenario. To know the BDD process for software testers, it means knowing that their aim is not to discover bugs, however, to counteract them in the beginning period of development.
2. Get a Clear & Precise Specification
It is really very essential to get clear and precise requirements from the product owner, need to have a complete understanding of the system’s behavior and consider all possible scenarios. At various discussions on specifications issues the testers’ objective is to think on how to break the system and building such scenarios is an approach to stop them after the project execution.
3. Jot Down the Feature Lists
After having an in-depth conversation with an enterprise, you need to scribble down all scenarios, requirements and expectations in the form of feature lists. The team of software testers should be a part of this process in order to make feature lists as wide as possible. You can draft better feature lists using Gherkin Language and its “background” feature which helps to avoid redundant tasks in each scenario, as well as “Data Tables” which allows setting certain data as a precondition to the tests. For better organization of scenarios and features, you can utilize sub-folders and tags.
4. Recognize the Implementation Process
You need to go through the implementation process of that specific feature lists and should collaborate with software developers. Comprehending each and every detail of the test code speeds up the complete process as you won't require extra time and efforts to figure out what would be the situation and what if something goes wrong.

5. Ensure Developers doesn't modify Feature Lists
Sometimes, it may happen that software developers like to modify something in feature lists assuming that it would make the code simple or more powerful. Such modifications means modifying requirements, and this must be acknowledged by the entire team and entrepreneurs/business owners.
6. Try to Understand the Missing Scenarios
If there arise an occurrence of inadequate understanding of a project concept and not looking on all potential outcomes, then the collection of scenarios probably won't be considered as sufficient. In BDD practice, a missing scenario is recognized as a bug, and that is the reason team should work on the missing scenarios as it is considered as an essential part of the project.
The biggest challenge for all the software testers is to work with BDD methodologies, but their involvement would be very important for the high-quality product.
So, these are few of the effective Behavior-driven development testing strategies that we considered are best in the market. Feel free if you have utilized anything other than the ones mentioned above.
