    Test Harness

    What is Test Harness?

    Anybody have come across Test Harness. Well It is kind of code written in the form of WhiteBox Testing. In SDLC Model i.e V Model there is one Level for Testing called as Integration Testing where each modules are been broken into sub modules for testing and integrating components.
    One Level in Integration Testing is System Integration Testing. Further in it there are different Strategies in it i.e Top Down approach and Bottom Up analysis.
    Here in Top Down approach, Stubs are used and in Bottom Up analysis Drivers are used.
    Stubs and Drivers are nothing but set of codes written unless the entire Code is not yet developed.
    So if Developer has not yet completed his part of work these Stubs and Drivers are written in functions and procedures.
    Hence this set of codes are called as Test Harness.

    Tracebility Matrix in Software Testing

    What exactly is Traceability Matrix?

    First of all by name itself Trace gives the meaning that something has to be traced. Similarly for Software Testing everything has to be traced. In large projects each and every data has to be maintained for future reference. So there is a concept called Traceability Matrix.

    So while preparing Traceability Matrix it can be done using Excel sheet or any other Test Management Tool  like Quality Center also. While preparing  Traceability Matrix in Excel these are the main things which need to be concentrated i.e,
    Sample Template
    Requirements ID  Req ID1.1  Req ID1.2  Req ID1.3  Req ID1.4  Req ID1.5 

    Test Cases id

    If a Tester leaves the organization and if he doesnot fill the report of   Traceability Matrix, how will the New Tester come to know what and all Test Cases have been written to which Requirement IDs.

    So  Traceability Matrix  gives the entire coverage of How many Test Cases have been written, how many Test Cases executed, which defect has been raised on which Test Cases etc.

    In Quality Center Test Coverage analysis prepares automatically all the reports and generates it after linkage is done by Testers of Test Cases to Requirements.
