Is it compulsary that a tester should study a Design Document for writing integration and system test casses
Answer :
First of all i wanto to tell to all , According to my knoledge 'Integration Testing' is not done by 'Test Engineer'.But if there is a chance to Test Engineer to participate in 'Integration Testing'.
Next,it is a must to study both Functional Requirement Specification and Design Document to conduct System Testing.
One more thing for a type of 'Adhoc testing' or 'Exploratory Testing' it is not must to study the design document
