How to put the above sentences in a better way ?
'recreate ' in the sentences means steps taken to create the error while testing of the functionality of the software.
Let me give you a clear picture . Let say a client using a software program, when click on the login button , he gets an error message.He could not figure out what has gone wrong and we would need to refer to us on how to solve this. So, we need to test this in our environment, whether we could be able to produce the same error message as the client did. To be able to create the error means that we could "recreate" this error.
