Functional Testing
• Transforming the way, you do functional testing by adapting reusability and automation to reduce time to market as well provide a holistic formula within your organization to bring this function of testing to the level it is required to advance your business.
• We bring an element of extending TDD (Test Driven Development) to include Functional TDD (Test Driven Development). While Extending the Product Specification to take full advantage of Behaviour Driven Development & Domain Specific Languages to enable a common shared language between the Core technologies and disciplines.
• Extending the life cycle of the Functional Test from Functional Test-Driven Development to Operation Support and coupling with DevOps processes can also provide important and fruitful advantages to reducing costs, time to market and tailored testing that is a true reflection of your software quality, enabling you to make the right decisions at the right time.

Functional Testing, at its basic level, is used to determine if the user-facing functions of a system perform correctly. It’s less concerned about back-end processing and more about outcomes: does a user get the expected result when interacting with the system? As such, Functional Testing is typically done manually, by human testers, but can also include a certain degree of automation.
• Functional Testing will only succeed if it aligns with the rest of the business in terms of strategy, values and fundamentals. It is most effective as part of a broader testing strategy that includes Test Automation, Exploratory Testing and Performance Testing, making sure every aspect of a system or software works as intended on the front-end, back-end, and through expected and unexpected conditions.
• While Functional Testing doesn’t require quite as much coding knowledge as more automated forms of testing, it can still be done using industry standard open-source tools like Selenium, which is similarly used for different types of testing, including Test Automation.
Following a similar pattern of discovery to other types of testing, Functional Testing is usually a linear process that takes into account:
• Identifying the test parameters and data
• Calculating expected outcomes based on the identified data
• Running test cases of typical system functions, based on client requirements
• Comparing the actual data to expected data
• Taking next steps to rectify any issues, or noting successful tests.
Functional Testing is usually done in conjunction with more formal, scripted testing and Test Automation. It should not be used as a substitute to other types of testing, rather as a complement. Some examples of when Functional Testing is typically done include:
• When a new system is developed and there is limited data on previous issues with the system.
• When you want to ensure the system performs optimally for its intended purpose, using human interaction and intuition on how it would typically be used.
• To get a better understanding of how a system works, and uncover any issues that deviate from those expectations.
• When it is absolutely critical that every precaution has been taken against potential issues, or when quality is the number one priority
