a.) Test Methodology
Testing methodology determines how an application will be tested and what will be tested. Example of methodologies: waterfall, agile etc.

b.) Test Scenario
Test scenario is a logical grouping of test cases and it mentions the sequence in which the test cases are to be executed.

c.) Test Case
A test case is a unit level document describing the inputs, steps of execution and the expected result of each test condition for every requirement from the BRD. Testers determine whether the application is working correctly or not based on the test case that is being executed. A test case is marked as "Pass" if the application works as expected and is marked as "Fail" if otherwise. Test cases also aide in generating test status metrics.

d.) Requirement traceability matrix
RTM is a matrix tying up requirements with the testcases. It is a way of making sure that every requirement has a corresponding testcase which will be tested thereby ensuring complete requirements coverage.
