Differences between White Box Testing and Grey Box Testing.

As we know that testing is the most important stage in the process of delivery of any application or software as it is only testing which not only validate the quality of an application but also provides an opportunity to the developer to improve its product.

Every application is being developed in some high or low level language which means some code has been written for its development so on the basis of knowledge to the tester about the application there is classification of testing namely White Box Testing and Grey Box Testing.

Following are the important differences between White Box Testing and Grey Box Testing.

Sr. No.KeyWhite Box TestingGrey Box Testing
1DefinitionWhite box is the type of testing in which tester know the internal functionality of the application and thus does the testing on functional basis.On other hand Grey box testing is the type of testing in which the tester is not aware about end to end internal functionality of the system or application so testing is mainly focus on primary functionality of the system instead of end to end coverage of internal functionality.
2Also known asAlong with primary functionality testing internal functionality also covered in white box testing so it is also known as clear box testing, structural testing or code based testing.On other hand Grey box testing only covers the primary functionality testing of an application hence testing is also termed as Translucent testing
3PerformerAs mentioned white box testing requires knowledge about internal functionality of the application so generally performed by testers and developers who have such knowledge.On other hand in case of Grey box testing no such knowledge required so it is generally done by end users along with testers and developers.
4Basis of testingAs testers are aware of internal functionality of the application hence they prepare the test data accordingly and tried to test almost every code scenario through these test cases.On other hand in Grey box testing the primary functionality knowledge is provided through high level data flow diagrams and database flow diagrams so these are the basis for this type of testing.
5Execution timeIt is obvious that as internal end to end functionality along with primary functionality is tested in this type of testing hence time of execution for this testing is more as compare to Grey box testing.On other hand as mentioned in above point only primary testing is tested in this type of testing hence execution time for this testing is less as compare to White box testing.
6AutomationAs most the part of this type of testing is based on the internal implemented code hence automation of this testing is possible and also algorithms for this testing could be developed.On other hand in case of Grey box testing no exposure to the internal implemented code hence possibility of automation of this testing is less as compare to that of White box testing.
