Do you have any knowledge about unit testing in software engineering?
Unit testing is one type of software testing.

Definition of Unit testing

Primary goal of unit testing is to test a smallest testable piece of system is called unit testing.
In STLC(Software testing life cycle) unit testing is performed before all types of testing described above.
Basically unit testing is performed by system developer. not by the system testing engineer.
When developer start to develop system, first of all he develop a unit of system one by one.
Then he have to test that unit or smallest piece developed by him is working fine as per requirement or not.
So unit testing is basic task of system.
