Before an application is put into production, it must undergo QA testing. LST makes use of both automated and manual testing tools and procedures to ensure quality. We can perform different types of testing such as functional, performance, stress or regression testing. LST uses a customized tool to create test plans that set the conditions for testing and then develop test scripts to ensure all conditions are tested. This procedure ensures that the application goes through a stringent testing environment before it is put into production.
