What is Functional Testing?
Functional testing is a form of testing and is a quality assurance process that helps to validate the system or components against various functional specifications and requirements outlined. Functional testing is a type of black-box testing as the source code of the application is not considered during the testing process.
The main purpose of this form of software testing is to test each functionality of the application by providing certain inputs and validating the outputs against the functional requirements.
In simpler words, this form of testing verifies whether the software performs in a way the users expect. As this type of testing is completely based on program specifications, it is also known as specifications-based testing. In this testing process, QA engineers focus on validating the system against the functional specifications and verifies the features against specified set of user specifications.
Why Functional Testing is required?
The need for functional testing is vital in validating the quality and functionality of the software. Through this software testing technique, quality assurance teams verify the software functionality based on the Software Requirements Specification (SRS) and ensures the system functions as per the user specifications.
This form of testing helps to check if the system is fixed for release and is error-free. This testing does not depend on any assumptions about the structure of the system, however, it ensures to deliver high-quality product. Basically, this testing method is used to test usability features, specific error conditions, checks accessibility features along with testing other important functions of the software.
How to perform Functional Testing?
Understand the requirements:
Before moving ahead for the functional testing process, the initial step is to have a thorough understanding of the business requirements. This is one of the very important steps to make further steps successful.
Prepare a test plan:
For successful functional testing, a good test plan is very important. Test engineers have to work on the test objectives so that it becomes easier to schedule and organize the test activities.
Write test cases:
Another important step after analysing the requirements and having a test plan is the creation of functional test cases. Here, three important aspects have to be worked upon which includes test data, test input, and test output.
Create input data according to requirements:
To test specific functionality, testers should create data and use it as an input to test the functionality of the application. This type of data is known as input data and this data which is used to test the applications is known as test input data.
Execute test cases:
The next step is executing the test cases by using the test input data identified during the creation of test cases.
Compare actual and expected outcome through result validation:
This is the major step where the actual test output is verified against the expected test result to mark pass or fail of the tests.
Log defects:
When comparing both actual and expected outputs, the variation of the difference identified between them is noted as log defects. Testers log defects to notify the development teams so that the defects get fixed at the earliest.
