    @ Nikhil- If you have basic idea of programming language then also you can do WBT. Just you need to learn on the fly each time on your project and need to get clear idea of the application working flow.
    It would be simple for you if you use any source code analysis tool if you have basic knowledge of the language in which your application is written.
    Source code understanding is most important for every white box test case as you modify the code to execute the test cases.
    White box testing can also be efficient just by seeing the source code of the application. When you know some weak points where you can think this code can break simply apply those cases manually as black box testing. This concept is referred as gray box testing.

    @ Shweta and Selvi: You can see a comprehensive list of testing tools listed on this page:

    The source code generally written by developers,but if a tester performs this WBT then :
    (i)How much in depth knowledge a tester should have abt a progg languge?
    (ii)If a another developer perform WBT for that module,will that be a better option?

    What should be done exactly??

    Hi friends,
    There are tools like nUnit,JUnit for white box testing.

    White box testing is done mainly by Developers , But If tester haves the required programing language knowledge then he can also perform white box testing.Tester should know the basics, like how to call function, pass parameters to function , store the values in database or text files… etc..

    not necessary that we should have white box knowledge to work in product based company… It depends on your role and type of testing…

    How to write test cases in White Box Testing??..

  13. Gaurav

    Swetha…firstly devide the testing into positive and negative testing.

    Determine the unit which is to be tested, then decide the positive test case input values, which includes the border inputs as well. Then set the expected results. And finally test them against the actual results.

    Same TBD with negative test cases.

    Can any1 answer dis question wid reason???

    Considering the following pseudo-code, calculate the MINIMUM number of test cases for statement coverage, and the MINIMUM number of test cases for decision coverage respectively.

    READ A
    READ B
    READ C
    PRINT “C must be smaller than at least one number”
    PRINT “Proceed to next stage”
    PRINT “B can be smaller than C”

    A 3, 3.
    B 2, 3.
    C 2, 4.
    D 3, 2.

  20. shivanand

    as there are 3 read statments(Read a,Read b,Read c) so we need 3 statment coverage
    consider C=3 B=2 and A=1,so if both IF condition satisfies than “PRINT “C must be smaller than at least one number” and “PRINT “B can be smaller than C”
    will be executed , and next if both IF condition fails than
    “PRINT “Proceed to next stage”
    PRINT “B can be smaller than C”
    will be executed .so we need min 2 branch coverage.

    so answer is D..
    let me know if m wrong….

    i think shiv you are wrong in explaining statement coverage. it means all executable codes should be executed atleast once.

    Hi Shiv,

    Following is a decision table to achieve decision coverage:

    Causes Values Combinations

    C>A T,F T T F F
    C>B T,F F T T F
    Effects/Results: 2 3 1 1


    1. B can be smaller than C
    2. Proceed to next stage
    3. C must be smaller than at least one number

    Now we can see that 3rd and 4th combinations are indifferent because, if the first condition fails, the result will be “B can be smaller than C” irrespective of the second condition. So we can reduce a combination and the table is as follows.

    Causes Values Combinations

    C>A T,F T T F
    C>B T,F F T –
    Effects/Results: 2 3 1

    So, we need 3 test cases for decision coverage. Please let me know if I am wrong.

    I am not sure how to write test cases for statement coverage. Should we write a test case for each line in the code? If so, what about projects where there are 10000 and more lines of code? Some one please elaborate!

    WBT is performed on develoer side i.e. if there is any errors during developing the code then they will conduct WBT.

    Generally, WBT is done by developers. so, I think we don’t worry about WBT.
    InCase If we have to do the WBT then just we have require basic knowledge on that particular domail/language.

    white box testing is not better in large application. i prefer black box testing better.

  29. Jitu

    @pinku – Type of testing is not decided by large or small application… It is decided at the level of testing..Levels like (unit testing ,Integration Test, System test,UAT Test)…White box is used mainly in Unit testing
