3. WHAT IS SOFT WARE TESTING ?
0 3
Software testing is a critical process within the realm
of software development that helps to identify
defects or bugs in a program or application. It
involves running the software in different scenarios
to ensure that it meets the specified requirements
and functions as intended. Testing can be done
manually by a tester or automated using specialized
tools. The goal of software testing is to ensure the
quality, reliability, and performance of the software
before it is released to end-users. It is an essential
part of the development cycle that helps in delivering
a seamless and error-free user experience.

1.Unit Testing: Testing individual units or components of the
software to ensure they function correctly.
2.Integration Testing: Testing how different units or components
work together when integrated.
3.System Testing: Testing the entire system as a whole to verify
that it meets the specified requirements.
4.Acceptance Testing: Testing the software from the end-user's
perspective to ensure it meets their needs.
5.Regression Testing: Testing to ensure that new changes do not
negatively impact existing functionality.

Unit testing is vital in software development, where
individual units are tested independently to identify bugs
early, enhance code quality, ease debugging, and
improve software reliability. It acts as a safety net for
future changes and helps teams create more robust
software applications.
Integration testing combines and tests individual
units to uncover inconsistencies in software
development. It ensures smooth functioning of
different components interacting, leading to a
robust and reliable end product.

7. INTERFACE TESTING REGRESSION TESTING
TYPES OF FUNTIONA L TESTING

Interface testing in software development
ensures components interact correctly. It
detects data communication issues,
protocols, and integration points to
enhance reliability and performance of
software applications.
Regression testing in software development
ensures recent changes do not impact existing
features. It helps identify defects introduced
during modifications, maintaining software quality
and reliability. Developers can confidently update
software while ensuring existing functionalities
remain intact through this iterative process.

System testing is essential in software
development to evaluate functionality and
performance, ensuring requirements are met. It
helps detect and fix issues before software
release, enhancing user experience and product
quality.
Sanity testing, or smoke testing, is a vital initial
software testing step to check basic functionality after
updates. It focuses on critical features, helps identify
early defects, and ensures software stability before
more testing. This testing phase saves time and
resources, instills confidence in software quality, and
aids informed decisions on further testing and
deployment.

9. USER ACCEPTAN CE
TESTING
TYPES OF FUNTIONA L TESTING

User acceptance testing (UAT) is vital in software
development as end-users validate the system to
ensure it meets requirements. It involves simulating
real-world scenarios to test usability, performance, and
user experience, identifying issues before the official
launch. Involving end-users provides valuable
feedback for refining the software to meet user needs.

10. COMPATA BI LI TY TESTING

Compatibility testing ensures
software functions well across various
devices, operating systems, browsers,
and networks. It helps developers
identify and fix issues, leading to a
better user experience.
COMPLIANCE TESTING
Conducting compliance testing ensures
adherence to rules and standards, identifies
deviations, and mitigates risks. It maintains
integrity, trust, ethical practices, and legal
obligations within organizations. Safeguards
against non-compliance, promotes
accountability, and transparency.

15. SOFT WARE TESTING LEVEL S
There are different levels of software testing that are crucial in ensuring the quality and
functionality of a software product. These levels include unit testing, integration testing, system
testing, and acceptance testing.
1.Unit Testing: This level involves testing individual components or modules of the software to
ensure that each unit functions correctly in isolation.
2.Integration Testing: Integration testing focuses on testing the interaction between different
units or modules to uncover any issues that may arise when they are integrated.
3.System Testing: System testing involves testing the entire software system as a whole to
validate that it meets the specified requirements and functions correctly in the intended
environment.
4.Acceptance Testing: Acceptance testing is the final level where the software is tested by end-
users to ensure that it meets their expectations and is ready for deployment.
By conducting thorough testing at each of these levels, software developers can identify and
address any issues early in the development process, ultimately leading to a more reliable and
high-quality software product.
