What is the difference between Test Case and Test Scenario?

A test case can be explained as a document that consists of a set of different variables and several conditions under which the feasibility of application software is to be aforehand determined as a way to verify its functionality. It aids testers to ascertain whether an application or system is actually functioning to the capacity of the demand and requirement of clients.

The test scenario is the sequence of several test cases needed to be executed each by each, to determine the functionality of a system or an application. A test case involves a single test that begins with a few steps that are performed one at a given time to test the output so as to verify if the application or system functions as required. The test scenario is just a test procedure or process of test cases, which is created by the tester based on the requirement of the business.
