3. What is Software ?
Software is a general term for the various kinds of Programs
used to operate Computers and related devices.
What is Testing ?
 Software testing is a process of executing a program or
application with the intent of finding the software bugs. It
can also be stated as the process of validating and verifying
that a software program or application or product: Meets the
business and technical requirements that guided it's design
and development.

4. Why Testing Tools Are Used
As the software industry grows, it becomes more and more
competitive and advanced for businesses to produce such good
quality software.
Testing plays a big part in the case of deadlines as testing can
take a long time on the software.
The production of the software and the quality together must
be increased for businesses to produce the Best possible
software.
With the aid of testing tools this can Increase efficiency and
get the deadlines met.

5. OBJECTIVES
Uncover as many as errors (or bugs) as possible in a given
product.
Demonstrate a given software product matching its
requirement specifications.
Validate the quality of a software testing using the minimum
cost and efforts.
Generate high quality test cases, perform effective tests, and
issue correct and helpful problem reports.

6. Error, Bug, Fault & Failure
 Error : It is a human action that produces the incorrect
result that produces a fault.
 Bug : The presence of error at the time of execution of the
software.
 Fault : State of software caused by an error.
 Failure : Deviation of the software from its expected result.
It is an event.

7.  Standard model used word wide to develop a software.
 A framework that describes the activities performed at
each stage of a software development project.
 Necessary to ensure the quality of the software.
 Logical steps taken to develop a software product.
SDLC(Software Development Life
Cycle)

8. Feasibility Study
Requirements Analysis & Specification
Design
Coding & Unit Testing
Integration & System Testing
Maintenance
Classical Waterfall Model
It is the oldest and most widely used model in
the field of software development.

9. Project Initiation
System Study
Summary Reports
Analysis
Regression Test
Report Defects
Execute Test Cases
( manual /automated )
Design Test Cases
Test Plan
Testing Life Cycle

10. Test Plan
 It is a systematic approach to test a system i.e.
software. The plan typically contains a detailed
understanding of what the eventual testing workflow will
be.

11. Test Case
 It is a specific procedure of testing a particular
requirement.
It will include:
Identification of specific requirement tested
Test case success/failure criteria
Specific steps to execute test
Test data

12. • Verification: The software should confirm to its
specification (Are we building the product right?)
• Validation: The software should do what the user really
requires (Are we building the right product?)
Verification vs. Validation

13. Testing Methodologies
 Black box testing
 White box testing

14. Black box testing
 No knowledge of internal program design or code
required.
 Tests are based on requirements and functionality.
requirements
input
events
output

15. White box testing
 Knowledge of the internal program design and code
required.
 Tests are based on coverage of code statements,
branches, paths, conditions.
Component
code
Test
outputs
Test data
DerivesTests

16. Testing Levels

17. UNIT TESTING
Tests each module individually.
Follows a white box testing (Logic of the program).
Done by developers.

18. INTEGRATION TESTING
Once all the modules have been unit tested, integration
testing is performed.
It is systematic testing.
Produce tests to identify errors associated with
interfacing.
Types:
 Big Bang Integration testing
 Top Down Integration testing
 Bottom Up Integration testing
 Mixed Integration testing

19. SYSTEM TESTING
 The system as a whole is tested to uncover
requirement errors.
 Verifies that all system elements work properly
and that overall system function and performance
has been achieved.
Types:
Alpha Testing
Beta Testing
Performance Testing

20. Alpha Testing
 It is carried out by the test team within the developing
organization .
Beta Testing
It is performed by a selected group of friendly customers.
Performance Testing
It is carried out to check whether the system meets the
nonfunctional requirements identified in the SRS document.

21. Acceptance Testing
 It is performed by the customer to determine whether to accept
or reject the delivery of the system.
Acceptance testing, a testing
technique performed to
determine whether or not the
software system has met the
requirement specifications. The
main purpose of this test is to
evaluate the system's
compliance with the business
requirements and verify if it is
has met the required criteria for
delivery to end users.

22. Types of Performance Testing:
Stress Testing
Volume Testing
Configuration Testing
Compatibility Testing
Regression Testing
Recovery Testing
Maintenance Testing
Documentation Testing
Usability Testing

23. Stress testing
It is the process of determining the ability of a computer
,network, program or device to maintain a certain level of
effectiveness under unfavorable condition. Such as
measuring the frequency of errors or system crashes.
Recovery testing
It is performed in order to determine how quickly the
system can recover after it has gone through system
crash or hardware failure. It is the forced failure of the
software in a variety of ways to verify that recovery is
properly performed.

24. Configuration testing
It is the process of testing the system with each one of
the supported software and hardware configuration.
The execution area support configuration testing by
allowing reuse of the created tests.
Compatibility testing
It is a type of software testing used to ensure
compatibility of the systems/application/website built
with various other object such as other web browser,
hardware platforms,users,operating system etc.This
type of testing helps to find out how well a system
perform in a particular environment.

25. Maintenance testing
It is a test that is performed to either identify equipment
problems, diagnose equipment problems or to confirm
that repair measures have been effective. It is uses system
performance requirements as the basis for identify the
appropriate components for further inspection or repair.
Usability testing
Usability testing is a technique used in user-centered
interaction design to evaluate a product by testing it on
users. This can be seen as an irreplaceable usability
practice, since it gives direct input on how real users use
the system.
