End to End Testing Vs System Testing
|End to End Testing||System Testing|
|Validates the software system as well as interconnected sub-systems||Validates just the software system as per the requirements specifications.|
|It checks the complete end-to-end process flow.||It checks system functionalities and features.|
|All interfaces, backend systems will be considered for testing||Functional and Non-Functional Testing will be considered for testing|
|It’s executed once System Testing is completed.||It’s executed after Integration Testing.|
|End to End testing involves checking external interfaces which can be complex to automate. Hence Manual Testing is preferred.||Both Manual and Automation can be performed for System Testing|
In Software Engineering, End to End Testing is the process verifying a software system along with its sub-systems. The biggest challenge in this testing is to have enough knowledge of the whole system as well as an interconnected sub-system.
