Unit & Parallel testing

Hai All,

Can anyone tell me the difference between Unit testing and Parallel testing.

Thanks in advance,



I understand that Unit Testing is the first step in the testing process, and is usually conducted by the programmer to ensure that a program operates as defined by the User. The programmer generally creates their own test cases, inputs the data to the program and verifies the results.

Parallel Testing is managed by the Users and is usually the last test before a system goes live. If the new system is replacing an existing one, both systems are operated side by side for a pre-determined period of time to ensure that the output from both systems is the same, or that any differences are expected.

If the application is a new one, then Parallel Testing is usually combined with a Simulated Work Environment.

Hope it helps.
