Requirements coverage without tracebabilty matrix

How to check whether the test case has covered all the requirements开发者_运维问答 other than tracebaility matrix.

There is no tool for this, if this is what you are looking for. Having said that 100% test coverage of requirements in unattainable. Your coverage should always be driven by specific situation, including the desires of the stakeholders. I recommend you read about context driven testing.

You can use a mix of traceability matrix and code coverage to get a reasonable idea if you want.
