Black Box Testing:
1. It is also called the functional testing wherein we
check the functionality of the applicaion through the
input and check what is the expected output.
2. The tester need not have any programming knowledge
3. the tester legally gives input and see the expected
output and need not worry about how the application arrived
at the output.
4. Testing is done by using outward facing iterface GUI
(Graphical user interface)
5. By black box testing we cannot make sure testing is done
completly.
White box testing:
1. It is also called Clear box testing wherein the tester
needs to examine the internal workings of the component or
items to be tested.
2. The tester should have programming knowledge.
3. Testing is done by using internal application
programming interface(API).
4. By this testing we make sure all codes of application
is being tested ie the Loop, Branch, Path coverage is
tested atleast once.

Black Box Testing:
Testing input/output without knowledge and/or regard of the internal code.
Commonly designed/executed by test team.
Black Box testing is also known as behavioural or closed box testing.
It is a software testing technique in which the internal workings of the item to be tested are not known to the tester or they are not taken into consideration.
Testing based on an analysis of the specification of a piece of software without reference to its internal workings.
The goal is to test how well the component conforms to the published requirements for the component.
White (Glass) Box Testing:
Testing input/output with full knowledge and/or regard of the internal code.
Commonly designed/executed by Developers.
White Box Testing is also known as structural,open box, clear box or glass box testing.
It is a software testing technique in which an explicit knowledge of the internal workings of the item to be tested are tested.
Testing based on an analysis of internal workings and structure of a piece of software.
Includes techniques such as Branch Testing and Path Testing.
Also known as Structural Testing and Glass Box Testing.
The basic difference between black box and white box testing is that in Black box testing we test only the external features by giving different combinations of inputs and their responses.
Black box testing is otherwise known as Specification based testing or Functional based testing.
