GREY BOX TESTING

SOFTWARE TESTING

Grey box testing is also called as grey box analysis which is a strategy of software debugging.  It is based on black box testing and white box testing. It is a technique where test of a software product is done with the partial knowledge of the internal process of a system. Grey box testing is a process where errors related to web systems are identified first. Generally it is a combination of black box testing and white box testing.

In white box testing internal structure is known

In black box testing internal structure of system is unknown

In grey box testing internal structure of system is partially known

Grey box testing tests the both sides of an application, presentation layer and code part. It is performed for the below reasons

  • It provides benefits of black box testing and white box testing.
  • It combines the inputs of both developers and testers and provides a better quality result.
  • It reduces the all over long process of functional and non functional types.
  • It provides a lot of free time for a developer to correct his errors.
  • Testing is conducted from user’s point of view apart from designer’s point of view.

The techniques used in grey box testing are:

Matrix testing:

It defines all the variables in the programs which are designed by developers.

Regression testing:

To check whether the new defects are introduced in the software due to the change in the previous version of program and software environment.

Pattern testing:

Unlike black box testing the grey box testing reaches to the depth of the program code and determines the cause for the failure.

It is named as Grey box testing because the product which has to be tested by a tester is like a grey box which is translucent box where the tester sees partially in it. The tester will not require the access to the code that is why grey box testing is unbiased and non-intrusive. To test web service application grey box testing is usually used.

  11. 1.How Grey box testing is different from white box and black box testing?
    _ Grey Box Testing is a combination of Both White and Black Box testing. In Grey box testing we have only a partial view or partial knowledge of the internal structure of the programme. But in Black box testing we no need to have the code or programme knowledge. In White box testing normally done by the developers should have the knowledge of internal code.

    2. What are the techniques used in grey box testing?
    – In Grey Box we have
    * Matrix testing – we test every variable of the programme
    * Regression testing – we test any new defects introduced in the new version software
    * Pattern Testing –

  12. How Grey box testing is different from white box and black box testing?
    Grey-box testing is a testing approach when the testers have only a partial access to the internal structure. Often it includes databases and the information about algorithms used, though it depends on the case. Still, testing is done from the point of view of an ordinary user like in the case of black-box testing.

    What are the techniques used in grey box testing?
    The test design techniques based on grey box testing:
    o matrix testing

  19. White Box testing is done at the program or component level and interfaces between the programs while developers still conducting the programs and interfaces between the programs. It is also known as structural testing because the internal structure of the software program components is tested.
    Black Box testing is done by the QA team and end users. They do not have any knowledge about the internal structure of the system.
    Grey Box testing is a software debugging strategy. It is a combination of White Box testing and Black Box testing. Like its name Grey Box Testing has the characteristics of Black Box and White Box testing that has made this kind translucent where you can have the partial knowledge of internal system but can’t access the code but errors related to web systems are identified first.
    The Techniques used in the Grey Box testing are,
    Matrix Testing: The developers design all variables for testing.
    Regression testing: It checks if a new defect has developed in the program due to the change in the previous version of the program and software environment.

    Matrix testing
    Regression testing

  41. In white box testing, you see the code, and in black box testing you do not. Gray box is a combo of the two where the tester has partial knowledge of the internal structure. The techniques used are matrix testing (defining all the variables), regression testing (checking if new defects are introduced by fixes), and pattern testing.

  42. Grey box testing is a technique used to test both sides of an application presentation layer and code part. It is known as a combination of white box testing and black box testing.
    Different techniques used in grey box testing are:
    Matrix testing.
    Regression testing.
    Pattern testing.

  43. Grey box testing is a combination of white box and black box testing. The difference is in Grey box testing, the internal structure is partially known unlike in white box testing where the internal structure is known and in black box testing where the internal structure is unknown. Grey Box Testing = White box testing + Black Box Testing
    Difference:
    Grey Box testing: internal structure is partially known
    White Box Testing: internal structure is known
    Black Box Testing: the internal structure is unknown

  44. Grey box testing is a combination of white box and black box testing. The difference is in Grey box testing, the internal structure is partially known unlike in white box testing where the internal structure is known and in black box testing where the internal structure is unknown. Grey Box Testing = White box testing + Black Box Testing
    Difference:
    Grey Box testing: internal structure is partially known
    White Box Testing: internal structure is known
    Black Box Testing: the internal structure is unknown
    Techniques used in grey box testing:
    The techniques used in grey box testing are: Matrix Testing, Regression Testing, Pattern Testing. Matrix testing: defines all the variables in the programs which are designed by developers.
    Regression testing: checks whether new defects are introduced in the software due to the change in the previous version of program and software environment.
