Functional Software Testing: What, Why and How?

If any functionality glitch or frame loss is noticed, it can be detrimental to its existence in the user’s favourite list. The Mashable.com uploaded a post in July 2017 which was about the upcoming most thrilling and addictive games like Destiny 2, Assassin's Creed, Mario+, and much more. It got viral as lots of people read, installed, tried and finally, loved them. When a certain application is installed on a device (computer or smart phone), it is expected to work smoothly without any glitches and create a never-forgetting impact. If any functionality glitch or frame loss is noticed, it can be detrimental to its existence in the user’s favourite list.

To avoid such situations, functional software testing comes into the picture. Do you know what actually is functional testing? How are functional testing services provided and in which fashion? No worries as we are going to discuss the same in this article.

What?
Functional testing is all about checking every function and feature of a software, whether they are in proper sync and at par with the developer’s expectations or not. All the functionalities of a software program are ideally tested by bestowing adequate input, evaluating the output and differentiating the current/actual results with the expected results. Either automated functional testing services or manual testing services can be performed to achieve the final goal. The whole process involves examining the APIs, user interface, server/client applications, security, database, and application’s functionality.

Why?
The basic objective of testing is to examine and be sure that the particular program is capable of seamlessly performing the fundamental activities for which it has been created or designed. The pin points where functional testing emphasizes on are:

● Mainline Testing
When every main function of a certain software application is checked, it is called mainline functional testing.

● Usability Check
On this level, an application’s basic usability is examined whether the user is able to navigate through the screens and reach the expected point without any hassle or not.

● Checking of Error Conditions
At this stage, the various testing techniques are used to check for error conditions. A tester evaluates whether suitable and relevant error messages are displayed at right point in time or not.

The process is highly critical to perform for the testers. A certain scope is aimed at the developer for a software program and in case a user doesn’t experience the same what was expected, the results can be catastrophic.

How?
Functional testing is a piece of cake for professional and experienced software testers but it isn’t a child’s play either. In order to perform the process without errors, the below mentioned steps are a must to follow:

1. Acknowledge the actual requirements
2. Recognize test data (test input)
3. Calculate the final input values with the expected outcomes/results
4. Execute time-to-time test cases
5. Compare actual results with expected results.

The automated functional testing is critical to perform as it may fail to deliver the expected results of an application. Teams practicing the same need to ensure that whichever functional testing strategy they are using is in place and runs efficaciously, giving the desired results.
