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 the external interfaces. The main purpose of end-to-end testing is to identify the system dependencies and to make sure that the data integrity and communication with other systems, interfaces and databases to exercise complete productions.
2. Unit Testing :
Unit Testing is the type of software testing level in which each individual components of a software are tested separately. It is generally performed by developer. It can’t be used for those systems which have a lot of interdependence between different modules. It does not allow for parallel testing.
Difference between End-to-end Testing and Unit Testing :
|End-to-end Testing||Unit Testing|
|In end-to-end testing, the behavioral flow of the software is tested.||Unit testing generally focuses on functional verification.|
|It tests the software system and the connected systems both combine.||In unit testing, software’s module are tested separately.|
|It is generally performed manually.||It is performed both manually and automated.|
|End-to-end testing is not cost efficient.||Unit testing is cost efficient.|
|End-to-end testing is performed for all testing processes at end.||Unit testing is performed for testing processes first.|
|Defects are not identified easily in end-to-end testing.||Defects are identified easily in unit testing.|
|Flow from end-to-end is tested.||Unit testing comprise of independent modules.|
|Knowledge about interconnected systems is required.||Knowledge of interconnected systems is not required.|
