    Re: Bug

    An uncovered or unidentified bug which is existing in the system over a period of time is referred as Latent Bug. The bug may exists in the system for one or more versions of the software and may also be identified after its release.

    The problems caused by the Lateral bugs will not cause damage as of now, but they are just waiting to reveal themselves later.

    One good example of a Latent bug the reason for the Y2K problem. At the beginning the year was given only 2 numeric fields, but actually it needs 4 numeric fields. The problem prevails in the system for a long time and identified later and then fixed. Also the problem does not cause the damage all of a sudden and it caused only by the year 2000, which certainly needs 4 numeric field.

    It is very diffucult to identify the Latent Bug by using conventional testing techniques, it can be identified by doing code review or by usability testing which foresees the forth coming problems earlier.

    Re: Bug

    Big bang testing is end to end testing of entire application before just final release of the project.
    In short: Testing all at once!

    Hi Sudha rani,

    Big Bang Testing is one of the type of Integration Testing. Integration Testing in one in which the software units of an application are combined and tested for a communication interfaces between them.

    In Big bang approach every module is unit tested in isolation from other module and then each modules are combined all at a once and tested. For example, if there are Modules A, B, C, D and E then the Modules A is unit tested in isolation from other, B is unit tested in isolation from other....Like that all the modules till E are unit tested in isolation. Then all the Modules A through E were combined and integrated and then tested. This approach is called as Big Bang Approach.

    In Integration testing there are also other two approaches Bottom up and Top down approach.

    Re: Latent Bug

    Latent bug is nothing but a hidden bug which exists even after several releases of a build.

    Latent bugs are identified with time and use of software.
