For example, the complete product may include features like leave application, reports, employee details, performance tracker, etc. Outsource time consuming and critical software components. After determining if the software is doing what it should, non-functional testing can measure how well it performs in various circumstances. Doing it correctly the first time can eliminate costly and time-consuming repairs later and help keep customers happy. Determining who is better at manual testing vs. scripting and using automated functional testing tools is key to successful testing. If you get different results from the tests than you expected, you should record it. Create input data for functionalities to be tested according to specified requirements. Functional testing on every functionality takes place by offering proper input. 8. The tests also drive a more modular architecture with subsystems that have clear responsibilities. Verify that End user gets a notification email with proper reason upon payment failure. Functional Testing Checklist |Professionalqa.com Determine which functionality of the product needs to be tested.
