Difference between System Testing and End to end testing

System Testing

System Testing is the third level of software testing performed after Integration Testing and before Acceptance Testing. Normally, independent Testers perform System Testing. Usually, Black Box Testing method is used.

End To End Testing

End to end testing is to cover complete work flow of application use case. to complete the end to end flow of any use case you may need to cover testing of other individual application also. eg. if you are using end to end flow of an e Commerce application your application final steps is to take user to a payment gateway for making payment. now testing request and response of the payment gateway integration functionality is part of system integration testing or end to end testing.


Often System Testing & End-to-End Testing are considered to be same but that is not true. Both of them are different forms of testing with different test coverage.
