Functional testing is used to verify whether each of the function of the software application is operating in according to the requirement specification. Functional testing also shows “What the system does” and the main aim is to check as if the system is working perfectly or not.

There are 5 steps in Functional Testing:

  1. Preparation of test data based on the specifications of functions
  2. Business requirements are the inputs to functional testing
  3. Find out of output of the functions based on functional specifications;
  4. The execution of test cases
  5. Observe the actual and expected outputs.

You can even check out the details of the testing methodologies tool with the Software testing course certification.

Hope this justifies your query.

Functional testing is software testing aimed to check the ability of functional demands, that is the ability to do tasks necessary for the users.Functional testing is a type of software testing that evaluates the performance of individual functions of a software application. The purpose of functional testing is to ensure that the application and all of its individual functions work as they should in the real world and meet all requirements and specifications.

It’s typically approached from one of two perspectives:

  1. Requirements-focused testing, which prioritizes requirements based on risk criteria in order to evaluate the most critical and important features and functions first.
  2. Business-process-focused testing, which relies on knowledge of end-user business requirements to evaluate an application’s performance in the context of typical use cases.

There are several specific functional testing techniques. The two primary techniques include white box testing and black box testing, although there are additional techniques including:

  • Smoke testing.
  • Unit testing.
  • User acceptance testing.
  • Integration testing.
  • Interface testing.
  • System testing.
  • Localization testing.
  • Regression testing.
  • Globalization testing.

I hope this info is useful to u.

functional testing is the process through which QAs determine if a piece of software is acting in accordance with pre-determined requirements. It uses black-box testing techniques, in which the tester has no knowledge of the internal system logic.
