2. Software Testing ::
 Definition: Software testing can be stated as the
process of validating and verifying that a software
program/application/product:
1)meets the requirements that guided its design and
development;
2)works as expected;
3)can be implemented with the same characteristics.
4)satisfies the needs of stakeholders

3. Testing Classification::
Software testing can be classified as below
A) Verification
B) Validation
A) Verification:: It can be classified as below
a) Walkthrough (informal)
b) Inspection (formal)
c) Review (some formal)

4. Testing Classification::
 B) Validation: It can be classified as below
a) Black Box
b) White Box
a) Black Box: It also known as Behavioural Testing,
is a software testing method in which the internal
structure/design/implementation of the item being
tested is not known to the tester.
Example :A tester, without knowledge of the internal
structures of a website, tests the web pages by
using a browser; providing inputs (clicks,
keystrokes) and verifying the outputs against the
expected outcome.

5. Black Box Testing Classification::
Black box testing can be classified as below
 a) Functional
 b) Non-functional
 a) Functional: It can be classified as below
– 1)BVA(Boundary Value Analysis)
– 2)ECP(Equivalent Class Partitioning)
– 3)EG(Error Guessing)
– 4)UCBT

6. Black Box: Funational:BVA Testing::
 1)BVA:It can be classified as below
a) Book Reference
b) Indian Reference
a) Book Reference: Valid and invalid values
needs to be provided;Range::min-
1,min,max,max+1
Example:: Testing a number between 1 & 10
min=1,max=10
min-1=0;min=1;max=10;max+1=11
These values needs to be checked.

7. Black Box: Functional: BVA Testing ::
 b) Indian Reference :Valid range values
needs to provided:Range:min,min+1,max-
1,max
Example: Testing a number between 1 & 10
min=1
max=10
min=1,min+1=2,max-1=9,max=10
These values needs to be checked

8. Black Box: Functional: ECP Testing ::
 2)ECP:The input values needs to be divided into
invalid and valid values.
– Example:: date (dd/mm/yyyy) validation
Invalid inputs:1)blank; 2)whitespace;
3)35/12/2012; 4)12/15/2012; 5)12/12/20125;
6)121/121/121; 7)[whitespace] 12/12/2012;
8)12-12-2012; 9)2012/12/12;
10) 00/00/0000
Valid Input:17/06/1994

9. Black Box:Non Functional Testing ::
 GUI (Graphical User Interface)
 Usability
 Navigation
 Browser compatibility
 Hardware compatibility
 Regression
 Acceptance
 Sanity
 Smoke
 Alpha
 Beta

10. Black Box:Non Functional:GUI Testing
::
1)GUI:Below things needs to be checked
a) Spelling mistakes
b) Images width-height, title, text when images
showing disabled
c) Font
d) Resizing browser
e) Links color and text-decoration (visited;
unvisited; hover)
f) Check display components like links, texts,
radio button, check box ,i-frame

11. Black Box: Non Functional: Usability
Testing ::
2)Usability:
a) Application should be clean,sharp,easy to
look(color)
b) Proper messages should be there .Messages
should be meaningful and easy to understand
c) Application should be easy to use. Example:
login:: username and password fields height
gap is fine but submit button is too far from
those fields.The user then needs to wait to
think where is the submit button.

12. Black Box:Non Functional Testing ::
3) Navigation:
a)Links must redirect to particular page
b)Page navigation like previous and next button links
should be there for moving from one page to another
within the same application
c)Submit Button properly submits the application.
4) Browser Compatibility: A particular application
should be tested in different browsers and different
versions of the same browser.CSS and javascript
functionality should be tested.

13. Black Box:Non Functional Testing ::
5) Alpha: Testing performed by end-users with
developers.
6) Beta: Testing performed by end-users with end-
environment. There are no involvements of
developers.
7) Retest: Defects that are raised and after resolving
those defects while the build of the application
comes to testers, testers again test the resolved
defects.
8) Smoke: When a tester gets a build from developers,
he/she runs the application for first time to check if
there is any defects during start up of the application.

14. Black Box:Non Functional Testing ::
9) Regression: It is to ensure that a change, such as a
bugfix, did not introduce new faults.
10) Sanity: It is a combination of smoke and
regression testing. It is to test that the new built
delivered by developers is running successfully and
by going into deep in the application finding out
bugs. Example:If there is a form in the
application,first the application loads successfully
and then the form saves its data successfully
11) Acceptance: It is a test conducted to determine if
the requirements of a specification or contract are
met. Example: User Acceptance Testing (UAT) is
done by the people who give requirements for the
projects .If UAT is successful,the project is put on
