Difference between End-to-end Testing and Sandwich Testing
1. End-to-end Testing :
End-to-end testing is the type of software testing used to test entire software from starting to the end along with its integration with external interfaces. The main purpose of end-to-end testing is to identify system dependencies and to make sure that the data integrity and communication with other systems, interfaces and databases to exercise complete production.
2. Sandwich Testing :
Sandwich Testing is also called as the hybrid integration testing. It comprise the bottom-up approach testing and top-down approach testing, therefore it uses the advantage of both bottom up approach and top down approach. It also can not be used for those systems which have a lot of interdependence between different modules and it allows parallel testing.
Difference between End-to-end Testing and Sandwich Testing :
|S.No.||End-to-end Testing||Sandwich Testing|
|1.||In end-to-end testing, the behavioral flow of software is tested.||In sandwich testing, Top-down approach and Bottom-up approach is used for testing.|
|2.||It validated all the interfaces of the software.||It follows the specification of modules.|
|3.||It is generally performed manually.||It generally focuses on functional verification.|
|4.||It is cost efficient.||It is not cost efficient.|
|5.||In this, knowledge about interconnected systems is required.||In this, knowledge of interconnected systems is not required.|
|6.||In this, there is need of fewer resources for testing.||In this, there is need of large number of resources.|
|7.||It does not allow parallel testing.||It allows parallel testing.|
|8.||It validated all the interfaces of the software.||It validates the software system as per standards and specifications.|
