Functional Testing

What is Functional Testing?

Functional Testing is the process by which expected behaviour of an application can be tested. Web Functional testing is a process to test Web applications to detect if your web application is functionally correct. The main purpose of this testing is to test the functions of the software by giving suitable inputs, and getting the outputs against the software requirements.

As the source code of the application is not considered during the testing process, for that Functional testing is also known as Black box testing.

In other words, this test verifies whether the software performs the way users expect. It is also known as Specification-based testing, as this type of testing is specifically based on Specifications requirements of the program.

Why Functional Testing
is required?

Functional Testing is an integral part of software testing and quality assurance process and also helps in validating how well the software functionalities are working based on user requirements.

This form of testing helps to check if the system is fixed for release and is error-free. The need for functional testing is vital in validating the quality and functionality of the software.

Through this testing technique, Quality assurance teams verify the software functionality based on Software Requirements Specifications (SRS).

How to perform
Functional Testing?

1. Identify function that is to be performed

Before moving ahead for the functional testing process, the existing step is to have a deep understanding of the business requirements.

2.Create input data based on the specifications of functions

For specific functionality testing, testers should create data and use it as an input to test the application functionality. This data which is used to test the application is known as test input data.

3.Determine the output based on the specifications of functions

   The output must be well developed and concise otherwise the quality and performance of the completed development may be compromised.

4. Execute the test cases

  The next step is to executing the test cases by using the test input data identified during the creation of test cases.

5.Compare the actual and expected output

This is the crucial steps where the actual output is been compared against the expected output.

Tools used for Functional: Selenium, SoapUI


Our Functional Testing as a Service ensures that your system is ready for release

By analysing the Business Requirements and system identification, testcases are created for examine the functionality of application. Whether we perform Black Box or White Box testing, our aim is to deliver the final software product as expected by the end user.
