Understand the requirements : Prior to conducting functional testing, it is necessary to thoroughly understand the business requirements. Understand the requirements document specification and clarify any doubts and queries if there are any.
Prepare a test plan : An effective test plan is critical for successful functional testing. Test engineers need to focus on the objectives of tests so that planning and organizing test activities will become easier.
Write test cases : Write the test cases considering the software requirements and keeping all of the test scenarios in mind.
Create input data according to requirements : Testers need to prepare input data to test specific functionality of software applications. When this type of data is used to test an application, it is referred to as test input data. From these inputs, determine what the expected outcome should be.
Execute test cases : Next, the test input data is used to execute the test cases.
Compare actual and expected outcomes through the result validation : In this step, the actual test results are compared with the expected results to determine whether the test has passed or failed.
Log defects : The variation of the difference between the actual and expected output is referred to as a log defect. It is the task of the testers to log defects so that the development teams can fix them as soon as possible.
