End-To-End Testing

End to end Testing define that the flow of the software should be work as per the describe in the software requirement. End to end testing verifies that the for any input the right out put should be generated and that output used as a input to other system component to verifies the interaction between the component of the software.

End to end testing ensuring that the every component of the system and interaction between these component working in the real world scenario . We can say that there are proper communication between the Network, Databases, Hardware and with other applications which are connected with the software.

Lets give an example of end to end testing of a shopping site
  • User should be able to logged in
  • User should be able to search any product
  • User can be added that product into his/her cart
  • User can check out from that cart
  • User can able to payment with various payment method
  • User can be able to see the order detail page 
End to end testing perform after the Functional Testing and System Testing. End to end testing is similar to the System Testing with difference that End to end Testing also check the interconnection between the interfaces.

Causes of Software Defects

It is practically impossible that developer develop a bug free software and that software we can deliver without Testing. If the complexity of the software increased then there must be bugs that can harm the users who will use that software.
