    Re: Test Coverage Matrix

    The test coverage is documented as simple matrix called as test coverage matrix. In this test coverage matrix the test implementation and operations are mentioned in column and the test cases are mentioned in row. It is a very good technique for test coverage. Traceability matrix is used in a software development process and is sued with high level requirements which correlate two base lined documents.

    Re: Test Coverage Matrix

    The answer was very useful but could you give a example of test coverage matrix. Also it would be nice if you could throw highlight on at what stages of software development life cycle the test coverage matrix and traceability matrix gets applied

    hi,

    traceability matix serves in mapping the test cases to the requirements. It serves as a checklist wherein all the requirements (of srs) are listed and the test cases covering the corresponding requirement is listed against each requirement. Every company may have their own template for rtm, but they serve the same purpose as described above.

    Test coverage matrix, on the hand, is also a checklist which ensures that the functionality of the given screen(unit) is checked in all possible combinations (positive and negative) which have not been covered in test cases. Test coverage matrix is usually prepared for a screen having large number of controls(textboxes, dropdowns, buttons etc) usually, test coverage matrix is prepared in a spread sheet having all the controls (textboxes, dropdowns, buttons etc) in the columns and then all possible entries in those fields in the rows with an ''yes'' or ''no'' in the rows against the controls listed in the columns. For example, consider a ''login'' screen wherein we have ''username'' and ''password" textfields.

    While preparing test coverage matrix, the first column will be ''s.no'' and the second will be ''username" and ''password" will be the third field followed by ''ok'' and ''cancel'' button. Then, in the first row for s.no 1, enter ''yes'' for both ''user name'' and ''password'' columns, ''yes'' implying that a value is entered in that field. In the second row, enter ''yes'' and ''no'' and in the third row, ''no'' and 'yes'' and so on.

    The complexity increases with the number of controls in the screen. Each of the row is considered as one condition and executed while testing. This is how we prepare test coverage matrix. (this is a black box testing technique). Hope i have made sense. Cheers

    the explination for traceabality matrics is correct. but it also includes all software development actvities include coding, design, etc but when come to test coverage matrics it only depends on how the testing is done on perticular madule in all the aspect, means different types of testing like functinal , system( performance, compatabality etc)

    Re: Test Coverage Matrix

    Hello all the discussion is really interesting. But it would be great if we could add all the types of matrix involved in Testing process so that we all could get knowledge shared about all the matrix. Could anyone initiate this. Since I am not aware of the matrix I am not initiating. Someone could take the lead.

    Re: Horizontal traceability Matrix

    hi

    Bidirectional is backward and forward tracebility.


    Forward tracebility starts from requirements, then the design and code


    Backward tracebility means the opposite or rather you can say reverse direction.We see that end product has met requirements or not!
    bye

    Re: traceability matrix

    tracability matrix is nothing but mapping between system requirements and test cases. it is used to check whether all the functionalities are covered or not.

    It is written by testers.

    s.no,tcd no,bdd no,fpd, something like this but its not complete..

    Re: traceability matrix

    A method used to validate the compliance of a process or product with the requirements for that process or product. The requirements are each listed in a row of the matrix and the columns of the matrix are used to identify how and where each requirement has been addressed.

    Re: What are the types of Metrix?

    Metrics are measurements. Measurements are inevitable in order to have project estimates(such as cost, time, man hours..)
    Basically there are two types of metrics from what i know.
    1. Process related metrics
    2. Product related metrics

    Re: traceability matrix

    The purpose of traceability matrix is to ensure that mapping in between requirements of the customer and test cases designed by testengineers.

    It is prepared by QA/TTL.

    By using this matrics we can find out
    1. whether all testcases are completed w.r.t requirements
    2. How many test cases are passed How many testcases are failed
    3. How many defects are fixed and how mnay are yet to be fixed when any of the testcases are failed

    So that this matrix consists of coloumns from BRD to until defects are resolved that means BRD, FRS, Testcase ID, Test cases description, test cases P/F, defect ID, defect description, Defect closed/fixed/resolved.
