assertNotSame() is a built in JUint function to test your java programs before deploying the application on your production environment/server. In this tutorial, we are going to share the junit assertNotSame example.
assertNotSame() function checks two objects do not refer to the same object. If they do refer to the same object, an AssertionError is thrown.
Example 1. assertNotSame() Function.
