MCQs On Software Testing Through Software Life Cycle

This set of multiple choice question on software testing through software life cycle includes the collections of MCQ questions on different test levels such as component testing, integration testing, system testing and acceptance testing. It also includes objective questions on different test types such as functional testing, non-functional testing, structural testing, regression testing and their characteristics. You will also get additional questions about maintenance testing, black-box testing, component testing, confirmation testing etc.
