There are various reports we normally prepare in QA:
-> Test summary Report – It is a report that has a list of the total test cases, list of executed test cases, remaining test case to be executed, executed date, pass/fail
-> Defect Report – In this report, we normally prepare a list of a defect in spreadsheet e.g. to defect #001
-> Traceability Matrix [also called RTM (Requirement Traceability Matrix)] Report – the document which shows the relationship between the functionalities or the business rules and the test cases. So, with the help of Traceability Matrix, we make sure that we include all the functionalities in our test cases according to the requirement document.
