What is functional testing and how does it work?

Recognize the requirements:

The first stage in the functional testing process is to have a comprehensive understanding of the business requirements. This is a critical stage in ensuring the success of subsequent steps.

Prepare a test plan:

A good test plan is essential for successful functional testing. Test engineers must work on the test objectives so that scheduling and organizing test operations becomes easier.

Create functional test cases:

After analyzing the requirements and creating a test plan, another crucial step is to create functional test cases. Test data, test input, and test output are three significant factors that must be addressed here.

Create input data based on requirements:

In order to test specific functionality, testers should create data and use it as input to test the application’s functioning. This form of data is referred to as input data, and the data used to test applications is referred to as test input data.

Execute test cases:

The next step is to run the tests using the test input data that was identified during the meticulous test case construction process. This ensures thorough coverage and accurate validation of the system’s functionality and performance.

Compare the actual and expected results through result validation:

This is the most important stage, where the actual test output is compared to the expected test result to determine whether the tests are passed or failed.

When comparing actual and predicted outputs, log faults are defined as the variance of the difference found between them. Defects are reported by testers to development teams so that they can be fixed as soon as possible.
