The quality of software systems may be expressed as a collection of Software Quality Attributes. When the system requirements are defined, it is essential also to define what is expected regarding these quality attributes, since these expectations will guide the planning of the system architecture and design.
Software quality attributes may be classified into two main categories: static and dynamic. Static quality attributes are the ones that reflect the system’s structure and organization. Examples of static attributes are coupling, cohesion, complexity, maintainability and extensibility. Dynamic attributes are the ones that reflect the behavior of the system during its execution. Examples of dynamic attributes are memory usage, latency, throughput, scalability, robustness and fault-tolerance.
Following the definitions of expectations regarding the quality attributes, it is essential to devise ways to measure them and verify that the implemented system satisfies the requirements. Some static attributes may be measured through static code analysis tools, while others require effective design and code reviews. The measuring and verification of dynamic attributes requires the usage of special non-functional testing tools such as profilers and simulators.
In this talk I will discuss the main Software Quality attributes, both static and dynamic, examples of requirements, and practical guidelines on how to measure and verify these attributes.
Integration testing verifies the interfaces between software modules. It has two categories: bottom-up integration starts with unit testing, then subsystem testing, and finally system testing; top-down integration starts with the main routine and tests subroutines in order, using stubs. Automated tools can help with integration testing, such as module drivers, test data generators, environment simulators, and library management systems.
This document provides an overview of software testing concepts and definitions. It discusses key topics such as software quality, testing methods like static and dynamic testing, testing levels from unit to acceptance testing, and testing types including functional, non-functional, regression and security testing. The document is intended as an introduction to software testing principles and terminology.
This document discusses software quality assurance (SQA). It defines SQA as a planned set of activities to provide confidence that software meets requirements and specifications. The document outlines important software quality factors like correctness, reliability, and maintainability. It describes SQA objectives in development and maintenance. Key principles of SQA involve understanding the development process, requirements, and how to measure conformance. Typical SQA activities include validation, verification, defect prevention and detection, and metrics. SQA can occur at different levels like testing, validation, and certification.
Software testing is an important phase of the software development process that evaluates the functionality and quality of a software application. It involves executing a program or system with the intent of finding errors. Some key points:
- Software testing is needed to identify defects, ensure customer satisfaction, and deliver high quality products with lower maintenance costs.
- It is important for different stakeholders like developers, testers, managers, and end users to work together throughout the testing process.
- There are various types of testing like unit testing, integration testing, system testing, and different methodologies like manual and automated testing. Proper documentation is also important.
- Testing helps improve the overall quality of software but can never prove that there
This document discusses different process models used in software development. It describes the key phases and characteristics of several common process models including waterfall, prototyping, V-model, incremental, iterative, spiral and agile development models. The waterfall model involves sequential phases from requirements to maintenance without iteration. Prototyping allows for user feedback earlier. The V-model adds verification and validation phases. Incremental and iterative models divide the work into smaller chunks to allow for iteration and user feedback throughout development.
Black box testing is a software testing technique where the internal structure and implementation of the system is not known. It focuses on validating the functionality of the system based on requirements and specifications. Some key techniques of black box testing include equivalence partitioning, boundary value analysis, and error guessing. Equivalence partitioning divides test cases into equivalence classes based on expected behavior. Boundary value analysis tests values at the boundaries of equivalence classes. Error guessing involves creating test cases based on intuition about potential errors. Black box testing is applied at various levels including unit, integration, system, and non-functional testing.
The document discusses software estimation and project planning. It covers estimating project cost and effort through decomposition techniques and empirical estimation models. Specifically, it discusses:
1) Decomposition techniques involve breaking down a project into functions and tasks to estimate individually, such as estimating lines of code or function points for each piece.
2) Empirical estimation models use historical data from past projects to generate estimates.
3) Key factors that affect estimation accuracy include properly estimating product size, translating size to effort/time/cost, and accounting for team abilities and requirements stability.
The document discusses the key characteristics of software quality assurance (SQA), including the high complexity of software, limited opportunities to detect defects, and need for teamwork and coordination. It defines important SQA terms like software quality, errors, faults, and failures. The document outlines nine common causes of software errors and provides definitions for SQA and its objectives to systematically ensure software meets requirements and is developed within schedule and budget.

A brief of that is try to explain here..
A Trust of the Customer on Product is solely based on the Effective QA
QA and testing are both important for software quality but have different goals. QA is a preventative, process-oriented activity aimed at preventing bugs, while testing is product-oriented and aimed at finding bugs. Key differences between QA and testing are outlined. The document also defines terms like quality control, verification and validation. It describes various testing types like unit, integration, system and acceptance testing as well as techniques like black-box vs white-box testing and manual vs automated testing. Concepts covered include test plans, cases, scripts, suites, logs, beds and deliverables. The importance of a successful test plan is emphasized.
Testing is the process of executing software to find defects and verify requirements are met. It involves executing a program or modules to observe behavior and outcomes, and analyze failures to locate and fix faults. The main purposes of testing are to demonstrate quality and proper behavior, and to detect and fix defects. Testing strategies include starting with individual component tests and progressing to integrated system tests. Different techniques like black-box and white-box testing are used at various stages. Manual testing is time-consuming while automated testing is faster and more reliable. Testing continues until quality goals are met or resources run out. Debugging locates and removes defects found via testing.
Testing is the process of validating and verifying software to ensure it meets specifications and functions as intended. There are different levels of testing including unit, integration, system, and acceptance testing. An important part of testing is having a test plan that outlines the test strategy, cases, and process to be followed. Testing helps find defects so the product can be improved.

Group #8, represented by Haris Jamil, discussed various types of software testing for their information technology project. They will review object-oriented analysis and design models, conduct class testing after coding, and integration testing within subsystems. The types of testing included are: object-oriented testing, requirement testing, analysis and design testing, code testing, user testing, integration tests, and system tests. Stages of requirement-based testing were defined as well as analysis testing, design testing techniques, code-based testing, integration testing strategies, system testing purposes, and user acceptance testing. Scenario-based testing was also explained.
Unit 8 discusses software testing concepts including definitions of testing, who performs testing, test characteristics, levels of testing, and testing approaches. Unit testing focuses on individual program units while integration testing combines units. System testing evaluates a complete integrated system. Testing strategies integrate testing into a planned series of steps from requirements to deployment. Verification ensures correct development while validation confirms the product meets user needs.
This is the most important topic of OOAD named as Object Oriented Testing. It is used to prepare a good software which has no bug in it and it performs very fast. <a href="https://harisjamil.pro">Haris Jamil</a>
The document discusses various topics related to software testing such as the testing life cycle, requirement traceability matrix, test planning, different types of testing, challenges in testing, test team approaches, and cost aspects. It emphasizes that testing is an important process to identify defects and improve quality but is often undervalued. A structured approach and clear policies are needed to make testing effective. Tracking metrics like defect trends and test team efficiency can help optimize the testing process.
Software testing involves verifying that a software program performs as intended. There are different types of testing including black box, white box, unit, integration, system, and acceptance testing. The goal is to detect bugs and ensure the software functions properly before it is released to end users.
This document discusses software testing practices and processes. It covers topics like unit testing, integration testing, validation testing, test planning, and test types. The key points are that testing aims to find errors, good testing uses both valid and invalid inputs, and testing should have clear objectives and be assigned to experienced people. Testing is done at the unit, integration and system levels using techniques like black box testing.

The Design and Analysis of Algorithms.pdfSaqib Raza
Here are the key points made in the preface:
- Algorithms play a central role in both computer science and practice. There are two main approaches to presenting algorithms in textbooks - by problem type or by design technique.
- The author believes organizing by design technique is more appropriate for an introductory algorithms course. This is because it provides tools for designing new algorithms, classifies known algorithms by underlying idea, and the techniques have general problem-solving utility.
- However, the traditional classification of design techniques has shortcomings from theoretical and educational perspectives. Specifically, it fails to classify many important algorithms.
- This limitation has forced other textbooks to depart from the design technique organization and include chapters by problem type instead.

• Software Testing?
• Software Testing Goals?
• Defects and Failures?
• Static VS Dynamic Testing?
• Types of Software Testing?
• Software Testing Life Cycle?
• Testing and Inspection?
• Stages of Testing?
3. What is Quality?
“A distinctive attribute or characteristic possessed by
someone or something or Degree of excellence
achieved”
Oxford Dictionaries definitions
4. What is Software Quality?
• Pressman's definition:
“Conformance to stated functional and performance requirements”
• IEEE Definition:
“The degree to which a system, component, or process meets specified
requirements”
• German Industry Standard:
"Quality comprises all characteristics and significant features of a product or an
activity which relate to the satisfying of given requirements“
5. What is Software Quality Assurance?
• Software quality assurance (SQA) consists of a means of monitoring
the software engineering processes and methods used to ensure
quality.
• The function of software quality that assures that the standards,
processes, and procedures are appropriate for the project and are
correctly implemented.
• Specified standards are used to define the development criteria that
are used to guide the manner in which software is engineered
6. Software Testing
• Software testing is a method of assessing the functionality of a
software program
• 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
• Testing is intended to show that a program does what it is intended to
do and to discover program defects before it is put into use.
8. Defects and Failures
• Not all software defects are caused by coding errors
• Expensive defects are requirement gaps
• Non-functional requirements such as usability, performance, and
security.
• A programmer makes an error (mistake), which results in
a defect (fault, bug)
• Defect can turn into a failure
9. Static VS Dynamic Testing
• Reviews, or inspections are referred to as static testing
• Actually executing programmed code with a given set of test cases is
referred to as dynamic testing
• Static testing involves verification, whereas dynamic testing
involves validation
10. Types of Software Testing
• Compatibility testing
• Smoke testing (basic problems that will prevent it from working)
• Regression testing (old bugs that have come back after change)
• Acceptance testing(User)
• Alpha Testing (simulated or actual operation) and Beta Testing
• Functional Testing (specific action or function of the code)
• Non-functional Testing (behavior under certain constraints)
• Performance Testing (responsiveness and stability under a particular
workload)
11. Types of Software Testing
• Usability testing (User interface is easy to use and understand)
• Accessibility testing (Under Certain Code or Standard)
• Security testing (Penetration)
• A/B testing (effect of one and other)
• Concurrent testing (basic operations and basic input to determine
basic faults)
• Many More
12. Software Testing Life Cycle
• Total Quality Assurance
• QA in every phase of development V&V Model
• There is a typical cycle for testing:
1. Test planning:
Test strategy, test plan. Since many activities will be carried out during
testing, a plan is needed. Priority, sensitivity etc.
2. Test development:
Test procedures, test scenarios, test cases, test datasets, test scripts to
use in testing software.
13. Software Testing Life Cycle
3. Test execution:
Testers execute the software based on the plans and test documents then
report any errors found to the development team.
4. Test reporting:
Once testing is completed, testers generate metrics and make final reports
on their test effort and whether or not the software tested is ready for
release.
5. Test result analysis:
Or Defect Analysis, is done by the development team usually along with the
client, in order to decide what defects should be assigned, fixed, rejected
(i.e. found software working properly) or deferred to be dealt with later.
14. Software Testing Life Cycle
6. Defect Retesting:
Once a defect has been dealt with by the development team, it is
retested by the testing team.
7. Regression Testing:
In order to ensure that the latest delivery has not ruined anything.
8. Test Closure:
Once the test meets the exit criteria, the activities such as capturing
the key outputs, lessons learned, results, logs, documents related to
the project are archived and used as a reference for future projects.
15. Testing and Inspection
• Software inspections Concerned with analysis of the static system
representation to discover problems (static verification)
• Inspections mostly focus on the source code of a system but any
readable representation of the software, such as its requirements or
a design model, can be inspected.
• When you inspect a system, you use knowledge of the system, its
application domain, and the programming or modeling language to
discover errors.
• Software testing Concerned with exercising and
observing product behaviour (dynamic verification)
• The system is executed with test data and its operational
behaviour is observed.
17. Inspection
• During testing, errors can mask (hide) other errors. Because inspection is a
static process, you don’t have to be concerned with interactions between
errors.
• Incomplete versions of a system can be inspected without additional costs.
If a program is incomplete, then you need to develop specialized test, to
test the parts that are available.
• As well as searching for program defects, an inspection can also consider
broader quality attributes of a program, such as compliance with
standards, portability and maintainability.
• Inspections and testing are complementary and not opposing verification
techniques.
• Both should be used during the V & V process.
• Inspections can check conformance with a specification but not
conformance with the customer’s real requirements.
18. Stages of Testing
• Development testing, where the system is tested during
development to discover bugs and defects.
• Release testing, where a separate testing team test a complete
version of the system before it is released to users.
• User testing, where users or potential users of a system test the
system in their own environment.
19. 1. Development Testing
• Development testing includes all testing activities that are
carried out by the team developing the system.
• Unit testing, where individual program units or object classes are
tested. Unit testing should focus on testing the functionality of
objects or methods.
• Component testing, where several individual units are integrated
to create composite components. Component testing should focus
on testing component interfaces.
• System testing, where some or all of the components in a system
are integrated and the system is tested as a whole. System testing
should focus on testing component interactions.
20. i. Unit Testing
• Unit testing is the process of testing individual
program in isolation.
• It is a defect testing process.
• Units may be:
• Individual functions or methods within an object
• Object classes with several attributes and methods
21. Object Class Testing
• Complete test coverage of all the features of the class
• Testing all operations associated with an object
• set and check the value of all attributes associated with
the object;
• put the object into all possible states. This means that you
should simulate all events that cause a state change.
• Inheritance makes it more difficult to design object
class tests as the information to be tested is not
localised.
22. ii. Component or Integration Testing
• Software components are often composite components that
are made up of several interacting objects.
• You access the functionality of these objects through the
defined component interface.
• Testing composite components should therefore focus on
showing that the component interface behaves according to
its specification.
23. iii. System Testing
• System testing of software or hardware is testing conducted on a
complete, integrated system to evaluate the system's compliance with
its specified requirements.
• System testing falls within the scope of black box testing, and as such,
should require no knowledge of the inner design of the code or logic.
• System testing tests the overall behavior of a system.
24. 2. Release Testing
• Release testing is the process of testing a particular release of a
system that is intended for use outside of the development team.
• The primary goal of the release testing process is to convince the
supplier of the system that it is good enough for use.
• Release testing, therefore, has to show that the system delivers its
specified functionality, performance and dependability, and that it
does not fail during normal use.
• Release testing is usually a black-box testing process where tests are
only derived from the system specification.
25. Release Testing and System Testing
• Release testing is a form of system testing.
• Important differences:
• A separate team that has not been involved in the system
development, should be responsible for release testing.
• System testing by the development team should focus on
discovering bugs in the system (defect testing).
• The objective of release testing is to check that the system meets
its requirements and is good enough for external use (validation
testing).
.
26. 3. User Testing
• User or customer testing is a stage in the testing process in which
users or customers provide input and advice on system testing.
• User testing is essential, even when comprehensive system and
release testing have been carried out.
• The reason for this is that influences from the user’s working
environment have a major effect on the reliability, performance,
usability and robustness of a system. These cannot be replicated in a
testing environment.
27. User Testing
• Alpha testing (Generic Software)
• Users of the software work with the development team to test the software
at the developer’s site.
• Beta testing
• A release of the software is made available to users to allow them to
experiment and to raise problems that they discover with the system
developers.
• Acceptance testing (Particular Company)
• Customers test a system to decide whether or not it is ready to be accepted
from the system developers and deployed in the customer environment.
Primarily for custom systems.
