Independent Software QA Testing Services
Functional testing is a type of software testing that seeks to establish whether or not an application feature works as per its intended requirements. A function is always compared to its corresponding requirement, ascertaining whether its output or action response is consistent with the end user’s expectations. The testing is usually executed by providing sample inputs, capturing the resultant outputs, and verifying them with the expected outcomes.
Some functional testing instances – High Priority
Do Remember…
Much unlike its non-functional testing counterparts, functional testing isn’t necessarily concerned with investigating the quality, security, or performance of the application’s source code. And it is not intended to gauge its speed, scalability, and reliability.
Rather, functional testing solely focuses on the outcomes or results of input processing and not the mechanics of it, determining whether the application accords with the basic minimum end user criteria and expectations.
The Cardinal Steps of Functional Testing
A functional testing plan usually follows 6 basic stages:
Identification Of Testing Goals
Functional testing goals are usually set toward the expected software features based on the project requirements. Testing goals include validating that the application works as intended to and handles errors and unexpected scenarios perfectly.
Create Test Case Scenarios
Developing a list of all possible (or at least the most important) test scenarios for a given feature. Test scenarios entail mapping the different pathways the feature will be used. For instance, in a payment module, the test scenarios may include currency conversion, notifying invalid or expired card numbers, and auto generating a PIN on a successful transaction completion along with a Billing ID.
Generating Test Data
Create test data that simulate normal feature use conditions based on the test scenarios identified. Test data can be entered manually (e.g. from an MS Excel spreadsheet or a printout) or via a script or test automation tool that auto inputs the data from a database, flat file, XML, or spreadsheet. Each set of collected data should also have associated datasets that log in the expected result that the earlier dataset should have generated.
Designing Test Cases
Involves creating test cases based on the different desired outcomes for the given inputs. Like entering an invalid credit card number, the application should ideally display an error message.
Executing Test Cases
Run the test cases through the application and compare actual outcomes against expected results. If actual and expected outputs are different, the feature has failed the test and a defect should be recorded.
Documentation, Tracking, and Resolving Defects
Once a defect is identified, it should be recorded on a formal tracking system that’s accessible to the entire project team. The requisite changes should be made to the application and the test case executed again to confirm resolution before a defect is marked as closed.
Early test case creation
Application or module coding should not be completed before starting to create test cases. Always remember, in the early phases of the project, the user requirements will be the most detailed. One can always come back and amend test cases later as and when needed.
Automation
Functional testing can often be arduous, repetitive, and time intensive. Automation can ensure desired functionality- identify defects, and save on test time and costs in the app delivery process. I Although it may not be possible, or even desirable, to automate all test cases, just getting the most important test cases off the manual list can nevertheless vastly improve test ROI.
Understanding the User’s POV
Functional testers must have a deep acknowledgment of the end user’s thought process. There are often many different types of users for each application (buyers, sellers, administrators, admins, data entry clerks, supervisors, etc.). And the typical navigation pathways of the application must be taken into account prior to creating each test plan.
Priorities
Having finite time and resources. All features can’t be tested. However, certain cardinal application functions are tagged high-priority and must, therefore, take higher testing precedence over low priority features.
At Thought Frameworks the two popular techniques for functional testing protocols are testing based on requirements and testing based on business scenarios.
Different provisions for functional testing solutions deployed are smoke testing, regression testing, integration testing, usability testing, functional system testing, end-to-end testing, cross browser functional testing, and multi version and concurrent testing.
Definition
The purpose of functional testing for a software application is to test each of its features and aspects by providing the appropriate input and re-verifying the expected outputs against the functional requirements.
Software functional testing involves a black box testing procedure. This does not take into consideration the source code of the application. Functional testing also checks user interface, APIs, database, security, and client and server communication. It can be performed both manually or can be fully automated.
A good functional testing protocol avoids defect leakage ensuring the quality of the end product.
The two most popular functional testing techniques deployed are:
Requirement based testing is a series of tests performed according to functional specifications provided by the client and verifying the product against the same.
Business scenario-based testing is a series of tests performed as per the industry functionality solely from a business perspective.
A functional testing plan or FTP is a quality measurement matrix of the functional components of a system. It is testing the application from the end user’s viewpoint

A Typical Functional Testing Service Environment at Thought Frameworks requires
1. How do you cover multiple browsers & mobile devices when you have less time?
We use smart test execution when there is less time and when the sprint duration is short, to ensure that we test based on the priority.
2. Communication between clients & QA team?
We communicate on Slack or Skype to clarify queries regularly if any and ensure that communication between the development team and testing team are always on the same page.
3. How does TF manage the regular test cycles?
We send Daily status reports, Weekly status reports and have weekly calls with clients.
4. How do we design test cases?
Refer to wireframe tools like Figma and design test cases with test case design techniques such as equivalence partition, Boundary value analysis, and error guessing.
5. How do we cover multiple mobile device testing?
We have a mobile test lab along with that we are using Browser stack for all the projects.

You know how you wouldn’t leave your front door wide open, right? Well, security testing is quite the same thing, like making sure your digital world is locked up tight so no one sneaks in and wreaks havoc unintended, (or maybe intended).(Sike!)
Okay, let’s be real. Procurement solutions sounds like a pretty dry topic at first, right? But here’s the catch—when you’re dealing with a solution as powerful and complex as iValua, quality isn’t something you can compromise on.
Implementing SAP systems can be a game-changer for businesses. It can streamline processes, improve productivity, and provide deeper insights into your operations.
Investing in an independent software testing team is not just a step in the ERP implementation process, it’s a strategic investment in the future success of the system.
