Difference between Test Scenario and Test Case in software testing

Test scenario:

• Test scenario is nothing but test procedure. A Test Scenarios have one too many relation with Test case, Means A scenario have multiple test case. Every time we have write test cases for test scenario
• Which will tells about functionality and it will be written by tester.
• During test analysis and design phase with the test basis as the input one would start identifying test condition and would determine high level test scenarios from these test conditions. At the later stages of test design 'concrete' test cases are defined from these test scenarios. One should be able to derive multiple test cases from one high level test scenario. 

Integration testing in software testing

Integration Testing

•       Testing the Integration of multiple units / modules

–      The objective is to test the application that is built by integrating the unit tested components

–      This tests interfaces between components, interactions with different parts of a system such as O.S, hardware and interfaces between systems.

–      Testers should concentrate solely on integration itself and not functionality of the individual modules to be integrated.

•       Performed by the Developer / Tester

•       Various approaches to Integration Testing could be :

Functional testing in software testing

Functional Testing

1.       Functional Testing is a Type of Testing conducted to – test the functionality of the application with respect to the requirements

2.       Also referred to as Black Box Testing

3.       Functional test cases are derived from the functional requirements of the software and are the basis for system testing. These help you in testing if the required functionality is working as per the specifications.

·         Ensure that the system under test is operational as per the customer requirements.

·         Verify whether the application is ready for release.
