Difference between System Testing and End to end 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.
- In system testing Product is tested against the requirement specification while in end to end testing, testing is done as per the business requirements.
- In system testing covers all functional and non-functional aspects while in end to end testing covers end to end flow.
- System testing executed when Integration testing is done while end to end testing executed after system testing.
- Manual and automation both testing is performed in System testing while in end to end testing automation is complex to perform. Hence manual testing is preferred.
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.
