What is the difference between Functional testing and Non functional testing? Give some examples in support of your answer?

Functional testing ensures that the function's and features of the application work properly,Non functional testing examines other aspect of how well the application works,Functional testing test the functionality of an application,Non functional tests the performance of these functions.

Example:

Example of Functional testing:

Imagine you are testing a web application that requires user to log in,In this case,functional testing simply is used to check if the login page is working as expected.

Example of Non Functional testing:

It focuses on the non functional aspect's of the application,For example using performance testing is a type of non functional testing that lets you check the performance of an application under heavy traffic of user load,Also it ensure that your application is stable and can handle heavy loads.

Boundary Value Analysis?

BVA involves software testing data near the specified limits or boundaries in the input specification,The aim is to test the input data's extreme values and boundary condition's,This include minimum and maximum values,Test input's at or near the defined minimum and maximum limits.

Decision Table Testing?

A decision table testing is the tabular representation of several input values,cases rules & test condition's,The decision table is a highly effective tool utilized for both requirement management & complex software testing,Through this table we can check and verify all possible combination's of testing condition.

Use Case testing?

Its a type of black box testing that helps in indentifying test cases that cover the entire system transaction by transaction from start to finish,It is a description of how a specific user uses the system,This method is widely used in developing test at systems or acceptance level'a.

LCSAJ Testing?

It means Linear Code Sequence & Jump & its a white box testing methodolgy used to determine the code coverage means what percentage of the code is executed with the existing test cases,It helps in designing new test cases,which can increase the coverage of the code under test.

Testing Techniques

1.Boundary Value Analysis.
Its based on testing the boundary values of valid and invalid partition's,the behaviour at the edge of the equivalence partition is more likely to be incorrect than the behaviour within the partition,So boundaries are an area where testing is likely to yield defect's,

It checks for the input values near the boundary that have a higher chance of error,Every partition has its minimum & maximum values,and these minimum & maximum values are the boundary values of a partition.

2.Decision Table Testing.
Decision table testing is a software testing technique used to test system behavior for different input combination and their corresponding system behavior( Output ) are captured in a tabular form & its also called as cause-effect table where cause and effects are captured for better test coverage

3.Use Case Testing.
Use case is a list of action taken by actor while interacting the system to achieve a goal,Here actor can be anyone either human user's or any other external system,Basically it is a technique that helps to identify test cases that cover the entire system,on transaction by transaction basis,from start to finish.

4.LCSAJ Testing.

It stands for Linear Code Sequence & Jump,its a white box testing methodology used to determine the code coverage i.e what percentage of the code is executed with the existing test cases,It helps in designing new test cases which can increase the coverage of the code under test.

What is Software testing ?
Software testing fundamental requirement is to deliver quality software on time & within the planned budget or even lesser than the planned,
Software testing is nothing but the process of executing the program with the intention of finding errors which is ultimate for a software tester to complete his or her expected tasks from the project.
What we need to know about software testing?
The important 2 terms we must know in software testing is Verification & Validation:
It means are we built or developed the software perfect as per the expectation then error free without any bugs& lastly have we built the software right & meets customer needs
What is the relevance of software testing?
It identify defects,
Reduce flaws,
& increase the overall quality of the system.
