Functional Testing:

Functional Testing is performed to verify application functionality correctly working or not. Functions correctly according to design specification, text input, test dealing (copy, paste and editing), string dealing, etc. Functionality Testing requires validating that an application program follows its stipulations and right executes all its involved functions. It implies a serial of tests which perform a feature-by-feature validation of behavior, using a broad range of normal and wrong input data. Some functional testing techniques include smoke testing, white box testing, unit testing and user acceptance testing etc.


Types of Functional Testing:

Functional testing defines in to two forms:

1. Positive functional testing: - This testing expect working out the application’s functions with valid input data and also verifying that the outputs results are correct or not.



2. Negative functional testing: - This testing requires working out application functionality using a combining of invalid inputs data, some unexpected working conditions and by some other “off-limits” scripts.

In the types of functional testing following testing types should be cover:

Unit Testing 
Smoke testing 
Sanity testing 
Integration Testing 
Interface Testing
System Testing 
Regression Testing
User Acceptance Testing (UAT) 

Unit Testing:

It is done by the development team or team having knowledge of code where they checked internal structure of codes, whereas testers are partly evolved in this type of testing where testing is done unit by unit. Unit testing is a software development process where which one has knowledge of code where individual units/component of software is tested. Or we can say that one by one and severally for proper operation. Unit testing is performed by the white box testing. Unit testing test specific pieces of code. Usually methods.


Method-
Unit testing is performed by using the white box testing method.

When it is performed?
Unit testing is the first level of testing and is performed anterior to integration testing.

Who perform unit testing?

Unit testing is mostly executing by independent software testers.

Tasks:

Prepare unit test plan and unit test case-
In unit test plan prepare document, review document, rework and base line.
In unit Test cases/scripts
Prepare test case/scripts, Review test cases/scripts, rework and baseline.

Unit Test-Perform testing
