Have you ever heard of functional testing? if you know it or you don’t know and want to know more information about it then this article is for you. We will provide you with information about what is functional testing, types, and examples in details.

What is Functional Testing 

Functional Testing is simply a quality assurance process to measure how good is the system also it is made to verify the functionality of the products. This testing is made only when system integration testing is complete including both the functional and non-functional requirements.

Functional Testing Types & Examples

 Alpha Testing

It is the most common type of testing used in the Software industry. The objective of this testing is to identify all possible issues or defects before releasing it into the market or to the user.

Acceptance Testing

It is performed by the client and verifies whether the end to end the flow of the system is as per the business requirements or not and if it is as per the needs of the end user. Client accepts the software only when all the features and functionalities work as expected.

Ad-hoc Testing

The name itself suggests that this testing is performed on an ad-hoc basis i.e. with no reference to the test case and also without any plan or documentation in place for such type of testing. The objective of this testing is to find the defects and break the application by executing any flow of the application or any random functionality.

Accessibility Testing

The aim of accessibility testing is to determine whether the software or application is accessible for disabled people or not. Here disability means deaf, color blind, mentally disabled, blind, old age and other disabled groups. Various checks are performed such as font size for visually disabled, color and contrast for color blindness etc.

Beta Testing

Beta Testing is a formal type of software testing which is carried out by the customer. It is performed in the Real Environment before releasing the product to the market for the actual end users.

Back-end Testing

Whenever an input or data is entered on front-end application, it stores in the database and the testing of such database is known as Database Testing or Backend testing. There are different databases like SQL Server, MySQL, and Oracle etc. Database testing involves testing of table structure, schema, stored procedure, data structure and so on.

Backward Compatibility Testing

It is a type of testing which validates whether the newly developed software or updated software works well with older version of the environment or not.

Black Box Testing

Internal system design is not considered in this type of testing. Tests are based on the requirements and functionality.
