The testing process ensures successful applications by taking care of three aspects:
Quality Assurance: An ongoing process within the software development life cycle that routinely checks the developed software to ensure it meets desired quality measures.
Functional Testing: The process of validating and verifying that a software program works as expected by meeting the business and technical requirements that guided its design and development.
Test Automation: The use of special software tools to control the execution of tests and comparing actual test results with predicted or expected results with minimum manual intervention.
