A software system is more than the code; it is a set of related artifacts; these may contain defects or problem areas that should be reworked or removed; quality-related attributes of these artifacts should be evaluated
Reviews allow us to detect and eliminate errors/defects early in the software life cycle (even before any code is available for testing), where they are less costly to repair
Most problems have their origin in requirements and design; requirements and design artifacts can be reviewed but not executed and tested
A code review usually reveals directly the location of a bug, while testing requires a debugging step to locate the origin of a bug
Adherence to coding standards cannot be checked by testing
Software testing is an investigation conducted to provide stakeholders with information about the quality of the product or service under test. I hope this ppt will help u to learn about software testing.

Intro to Unit Testing with test Driven DevelopmentJoel Cochran
Test Driven Development is a technique that requires Unit Tests for code to be written before the code itself. By placing the emphasis on testing, developers can define success before code is written. This helps us answer that elusive question of "when is code done?" TDD offers additional benefits such as only writing code you need to satisfy your requirements (YAGNI), and enhanced maintainability.

When Web-based business applications communicate with each other, producer applications ENQUEUE messages and consumer applications DEQUEUE messages. Advanced Queuing provides database-integrated message queuing functionality. Advanced Queuing leverages the functions of the Oracle database so that messages can be stored persistently, propagated between queues on different machines and databases, and transmitted using Oracle Net Services, HTTP(S), and SMTP.
An SQL JOIN clause combines columns from one or more tables in a relational database. It creates a set that can be saved as a table or used as it is. A JOIN is a means for combining columns from one (self-table) or more tables by using values common to each.
Constraints are the rules enforced on the data columns of a table. These are used to limit the type of data that can go into a table. This ensures the accuracy and reliability of the data in the database.
Constraints can be divided into following two types:
Column level constraints : limits only column data
Table level constraints : limits whole table data
Aggregate Functions
Generic programming is a style of computer programming in which algorithms are written in terms of types to-be-specified-later that are then instantiated when needed for specific types provided as parameters.
Generics are a facility of generic programming that were added to the Java programming language in 2004 within version J2SE 5.0. They were designed to extend Java's type system to allow “a type or method to operate on objects of various types while providing compile-time type safety”
The Java collections framework supports generics to specify the type of objects stored in a collection instance.
In computer science, a stream is a sequence of data elements made available over time. A stream can be thought of as items on a conveyor belt being processed one at a time rather than in large batches.
Streams are processed differently from batch data :
*Normal functions cannot operate on streams as a whole, as they have potentially unlimited data, and formally
*Streams are codata (potentially unlimited), not data (which is finite).
This contains:
*Getting started with New Dynamic Web Project
*Starting the tomcat server
*Running your project
*Changing the context root
*Changing welcome pages of your website
A business group is the highest level of organization and the largest grouping of employees across which you may report. A Business Group holds a complete, self-contained set of information on work structures, remuneration policies and employees. Each Business Group can have just one particular set of segments defined for its Job, Position, Grade, Employee Group and Cost Allocation key flex fields.
A business group is a basically Human Resources organization to which you assign employees. You assign each operating unit to a business group in the financial options setup. You can assign the same business group to different operating units including to operating units in different financial sets of books. You can setup a separate business group for each operating unit if you want to segregate and maintain each group of employees separately. Oracle provides one setup business group you can use.
Locations are shared across Business Groups in HRMS and with two other Oracle applications: Inventory and Purchasing. HRMS does not use some of the fields in the Location window. These fields are disabled for HRMS users. For example, the Legal Address check box is read-only and supports future functionality in Oracle Financials.
By default, the “Approvals Management Administrator” and “Approvals Management Business Analyst” responsibilities do not have any functions associated with them, because their access is restricted by Role Based Access Control (RBAC).

Cosmetic shop management system project report.pdfKamal Acharya
Buying new cosmetic products is difficult. It can even be scary for those who have sensitive skin and are prone to skin trouble. The information needed to alleviate this problem is on the back of each product, but it's thought to interpret those ingredient lists unless you have a background in chemistry.
Instead of buying and hoping for the best, we can use data science to help us predict which products may be good fits for us. It includes various function programs to do the above mentioned tasks.
Data file handling has been effectively used in the program.
The automated cosmetic shop management system should deal with the automation of general workflow and administration process of the shop. The main processes of the system focus on customer's request where the system is able to search the most appropriate products and deliver it to the customers. It should help the employees to quickly identify the list of cosmetic product that have reached the minimum quantity and also keep a track of expired date for each cosmetic product. It should help the employees to find the rack number in which the product is placed.It is also Faster and more efficient way.

Hierarchical Digital Twin of a Naval Power SystemKerry Sado
A hierarchical digital twin of a Naval DC power system has been developed and experimentally verified. Similar to other state-of-the-art digital twins, this technology creates a digital replica of the physical system executed in real-time or faster, which can modify hardware controls. However, its advantage stems from distributing computational efforts by utilizing a hierarchical structure composed of lower-level digital twin blocks and a higher-level system digital twin. Each digital twin block is associated with a physical subsystem of the hardware and communicates with a singular system digital twin, which creates a system-level response. By extracting information from each level of the hierarchy, power system controls of the hardware were reconfigured autonomously. This hierarchical digital twin development offers several advantages over other digital twins, particularly in the field of naval power systems. The hierarchical structure allows for greater computational efficiency and scalability while the ability to autonomously reconfigure hardware controls offers increased flexibility and responsiveness. The hierarchical decomposition and models utilized were well aligned with the physical twin, as indicated by the maximum deviations between the developed digital twin hierarchy and the hardware.

An Approach to Detecting Writing Styles Based on Clustering Techniquesambekarshweta25
An Approach to Detecting Writing Styles Based on Clustering Techniques
Authors:
-Devkinandan Jagtap
-Shweta Ambekar
-Harshit Singh
-Nakul Sharma (Assistant Professor)
Institution:
VIIT Pune, India
Abstract:
This paper proposes a system to differentiate between human-generated and AI-generated texts using stylometric analysis. The system analyzes text files and classifies writing styles by employing various clustering algorithms, such as k-means, k-means++, hierarchical, and DBSCAN. The effectiveness of these algorithms is measured using silhouette scores. The system successfully identifies distinct writing styles within documents, demonstrating its potential for plagiarism detection.
Introduction:
Stylometry, the study of linguistic and structural features in texts, is used for tasks like plagiarism detection, genre separation, and author verification. This paper leverages stylometric analysis to identify different writing styles and improve plagiarism detection methods.
Methodology:
The system includes data collection, preprocessing, feature extraction, dimensional reduction, machine learning models for clustering, and performance comparison using silhouette scores. Feature extraction focuses on lexical features, vocabulary richness, and readability scores. The study uses a small dataset of texts from various authors and employs algorithms like k-means, k-means++, hierarchical clustering, and DBSCAN for clustering.
Results:
Experiments show that the system effectively identifies writing styles, with silhouette scores indicating reasonable to strong clustering when k=2. As the number of clusters increases, the silhouette scores decrease, indicating a drop in accuracy. K-means and k-means++ perform similarly, while hierarchical clustering is less optimized.
Conclusion and Future Work:
The system works well for distinguishing writing styles with two clusters but becomes less accurate as the number of clusters increases. Future research could focus on adding more parameters and optimizing the methodology to improve accuracy with higher cluster values. This system can enhance existing plagiarism detection tools, especially in academic settings.
Hybrid optimization of pumped hydro system and solar- Engr. Abdul-Azeez.pdffxintegritypublishin
Advancements in technology unveil a myriad of electrical and electronic breakthroughs geared towards efficiently harnessing limited resources to meet human energy demands. The optimization of hybrid solar PV panels and pumped hydro energy supply systems plays a pivotal role in utilizing natural resources effectively. This initiative not only benefits humanity but also fosters environmental sustainability. The study investigated the design optimization of these hybrid systems, focusing on understanding solar radiation patterns, identifying geographical influences on solar radiation, formulating a mathematical model for system optimization, and determining the optimal configuration of PV panels and pumped hydro storage. Through a comparative analysis approach and eight weeks of data collection, the study addressed key research questions related to solar radiation patterns and optimal system design. The findings highlighted regions with heightened solar radiation levels, showcasing substantial potential for power generation and emphasizing the system's efficiency. Optimizing system design significantly boosted power generation, promoted renewable energy utilization, and enhanced energy storage capacity. The study underscored the benefits of optimizing hybrid solar PV panels and pumped hydro energy supply systems for sustainable energy usage. Optimizing the design of solar PV panels and pumped hydro energy supply systems as examined across diverse climatic conditions in a developing country, not only enhances power generation but also improves the integration of renewable energy sources and boosts energy storage capacities, particularly beneficial for less economically prosperous regions. Additionally, the study provides valuable insights for advancing energy research in economically viable areas. Recommendations included conducting site-specific assessments, utilizing advanced modeling tools, implementing regular maintenance protocols, and enhancing communication among system components.

Software Testing and Quality Assurance (BTCS-905)
Assignment 2
2. 2 | P a g e B y G u r p r e e t S i n g h
http://gsbprogramming.blogspot.in/
Very short questions
Q1: What is stress testing?
A: Stress testing is a software testing activity that determines the robustness of software by testing
beyond the limits of normal operation. Stress testing is particularly important for "mission critical"
software, but is used for all types of software. Stress tests commonly put a greater emphasis on
robustness, availability, and error handling under a heavy load, than on what would be considered
correct behavior under normal circumstances.
Q2: What is Cyclomatic complexity?
A: Cyclomatic complexity is a software metric (measurement), used to indicate the complexity of
a program. It is a quantitative measure of the number of linearly independent paths through a
program's source code. It was developed by Thomas J. McCabe, Sr. in 1976.
It is calculated by producing a ControlFlowGraph of the code, and then counting:
E = number of edges in the graph.
N = number of nodes in the graph.
P = number of nodes that are exit points
(last instruction, return, exit, etc.)
Then,
Cyclomatic complexity = E - N + P
The metric tries to capture the number of paths through the code, and thus the number of required
test cases. It is widely used, but has been criticized for not capturing the additional complexity
implied in nested control structures.
Q3: Define Object Oriented Testing
A: Object Oriented software testing has to deal with new problems introduced by the powerful OO
features such as en-capsulation, inheritance, polymorphism, and dynamic binding. A test strategy
can be defined as the order to unit testing and integration testing of the classes in an OO program.
The test order problem for the classes in an OO program can be stated as finding an order to test
the classes so that the effort required is minimum.
3. 3 | P a g e B y G u r p r e e t S i n g h
http://gsbprogramming.blogspot.in/
Q4: What is regression testing? When it is done?
A: Regression testing is a type of software testing that seeks to uncover new software bugs, or
regressions, in existing functional and non-functional areas of a system after changes such as
enhancements, patches or configuration changes, have been made to them. The intent of regression
testing is to ensure that changes such as those mentioned above have not introduced new faults.
One of the main reasons for regression testing is to determine whether a change in one part of the
software affects other parts of the software.
Regression testing has traditionally been performed by a

Q5: How loop testing is different from the path testing?
A: Loop testing a white box testing technique performed to validate the loops.
Path Testing is a structural testing method based on the source code or algorithm and NOT
based on the specifications. It can be applied at different levels of granularity.
Q6: What is client server environment?
A: Client server environment means that client computers (computers forming part of the network)
contact a server, generally a very powerful computer in terms of input/output, which provides
services to the client computers. These services are programs which provide data such as the time,
files, a connection, etc.
The services are used by programs client programs which run on client computers. This is why the
term "client" is applied (FTP client, email client, etc.), where a program is designed to run on a
client computer, capable of processing data received from a server (in the case of the FTP client
we are dealing with files whereas for the email client we deal with email email).
Q7: What is graph based testing?
A: Graph based testing is useful to represent a transaction or work flows. Cause and effect graphs
are generated and cyclometric complexity considered in using the test cases.
Q8: How security testing is useful in real applications?
A: Security testing is a process intended to reveal flaws in the security mechanisms of an
information system that protect data and maintain functionality as intended. Due to the logical
limitations of security testing, passing security testing is not an indication that no flaws exist or
that the system adequately satisfies the security requirements.

Q9: What are main characteristics of real time system?
A: A real-time system is one that must process information and produce a response within a
specified time, else risk severe consequences, including failure. Main characteristics of real time
system:
Large and complex: vary from a few hundred lines of assembler or C to 20 million
lines of Ada estimated for the Space Station Freedom
Concurrent control of separate system components: devices operate in parallel in the
real-world; better to model this parallelism by concurrent entities in the program
Extreme reliability and safety: embedded systems typically control the environment in
which they operate; failure to control can result in loss of life, damage to environment or
economic loss
Mixture of Hardware/Software: some modules implemented in hardware, even whole
systems, SoC
Q10: What are the benefits of data flow testing?
A: Data Flow testing helps us to pinpoint any of the following issues:
A variable that is declared but never used within the program.
A variable that is used but never declared.
A variable that is defined multiple times before it is used.
Deallocating a variable before it is used.

Q2: Assuming a real time system of your choice, discuss the concepts. Analysis and
design factors of same, elaborate
A: A real-time system is one that must process information and produce a response within a
specified time, else risk severe consequences, including failure. An example of real time system is
real time operating system.
A real-time operating system (RTOS) is an operating system (OS) intended to serve real-time
application process data as it comes in, typically without buffering delays. Processing time
requirements (including any OS delay) are measured in tenths of seconds or shorter.
Analysis & Design Factors:
An RTOS has an advanced algorithm for scheduling. Scheduler flexibility enables a wider,
computer-system orchestration of process priorities, but a real-time OS is more frequently
7. 7 | P a g e B y G u r p r e e t S i n g h
http://gsbprogramming.blogspot.in/
dedicated to a narrow set of applications. Key factors in a real-time OS are minimal interrupt
latency and minimal thread switching latency; a real-time OS is valued more for how quickly or
how predictably it can respond than for the amount of work it can perform in a given period of
time.
The most common designs are:
Event-driven which switches tasks only when an event of higher priority needs servicing, called
preemptive priority, or priority scheduling.
Time-sharing designs switch tasks on a regular clocked interrupt, and on events, called round
robin.
Time sharing designs switch tasks more often than strictly needed, but give smoother multitasking,
giving the illusion that a process or user has sole use of a machine.
Early CPU designs needed many cycles to switch tasks, during which the CPU could do nothing
else useful. For example, with a 20 MHz 68000 processor (typical of the late 1980s), task switch
times are roughly 20 microseconds. (In contrast, a 100 MHz ARM CPU (from 2008) switches in
less than 3 microseconds.) Because of this, early OSes tried to minimize wasting CPU time by
avoiding unnecessary task switching.
Scheduling
In typical designs, a task has three states:
Running (executing on the CPU);
Ready (ready to be executed);
Blocked (waiting for an event, I/O for example).
Most tasks are blocked or ready most of the time because generally only one task can run at a time
per CPU. The number of items in the ready queue can vary greatly, depending on the number of
tasks the system needs to perform and the type of scheduler that the system uses. On simpler non-
preemptive but still multitasking systems, a task has to give up its time on the CPU to other tasks,
which can cause the ready queue to have a greater number of overall tasks in the ready to be
executed state
Algorithms
Some commonly used RTOS scheduling algorithms are:
Cooperative scheduling
Preemptive scheduling
Earliest Deadline First approach
Stochastic digraphs with multi-threaded graph traversal

Q3: How testing in multiplatform environment is performed?
A: Software designed to run on more than one platform must undergo two tests. The first test is to
validate that the software performs its intended functions. The second test is that the software will
perform in the same manner regardless of the platform on which it is executed.
Each platform on which software is designed to execute operationally may have slightly different
characteristics. These distinct characteristics include various operating systems, hardware
configurations, operating instructions, and supporting software, such as database management
systems. These different characteristics may or may not cause the software to perform its intended
functions differently. The objective of testing is to determine whether the software will produce
the correct results on various platforms.
Testers face three major challenges when testing in a multiplatform environment. These challenges
are:
Determining the type of platform that users operate for the processing
Determining which software packages are available to those users
Determining the type of processing users will perform in a multiplatform environment
The following six tasks should be performed to validate that software performs consistently in a
multiplatform environment:
1. Define platform configuration concerns.
2. List needed platform configurations.
3. Assess test room configurations.
4. List structural components affected by the platform(s).
5. List interfaces platform affects.
6. Execute the tests.
Define Platform Configuration Concerns
The first task in testing a multiplatform environment is to develop a list of potential concerns about
that environment. The testing that follows will then determine the validity of those concerns. The
recommended process for identifying concerns is error guessing.

The testers need to determine whether the platforms available in the test room are acceptable for
testing.

List Structural Components Affected by the Platform(s)
Structural testing deals with the architecture of the system. Architecture describes how the system
is put together. It is used in the same context that an architect designs a building.
List Interfaces the Platform Affects
Systems tend to fail at interface points—that is, the points at which control is passed from one
processing component to another (for example, when data is retrieved from a database, output
reports are printed or transmitted, or a person interrupts processing to make a correction). The
purpose of this task is to identify those interfaces so that they can be tested.
Execute the Tests
The platform test should be executed
Q4: Explain graph based testing in detail
A: Graph based testing is useful to represent a transaction or work flows. Cause and effect graphs
are generated and cyclometric complexity considered in using the test cases.
Graph-based testing first builds a graph model for the program under test, and then tries to cover
certain elements in the graph model.
Each and every application is buildup of some objects. All such objects are identified and graph is
prepared. From this object graph each object relationship is identified and test cases written
accordingly to discover the errors.
The software engineer begins by creating a graph- a collection of nodes that represent objects;
links that represent the relationships between objects; node weights that describe the properties of
a node(e.g., a specific data value or state behavior); and link weights that describe some
characteristic of a link.

General outline for graph based testing with respect to language processor is:
Identify the grammar for the scenario. In some cases the scenario can be context-free
grammar, which may require a more sophisticated representation of a “state diagram”
Design test cases corresponding to each valid state-input combination
Design test cases corresponding to the most common invalid combination of state-input.
Q5: Differentiate between Equivalence partitioning and boundary value analysis
A: Boundary value analysis and equivalence partitioning both are test case design strategies in
black box testing.
Equivalence Class Partitioning
In this method the input domain data is divided into different equivalence data classes. This method
is typically used to reduce the total number of test cases to a finite set of testable test cases, still
covering maximum requirements.
In short it is the process of taking all possible test cases and placing them into classes. One test
value is picked from each class while testing. Using equivalence partitioning method above test
cases can be divided into three sets of input data called as classes. Each test case is a representative
of respective class. Test case values are selected in such a way that largest number of attributes of
equivalence class can be exercised.
Equivalence partitioning uses fewest test cases to cover maximum requirements. It can be used at
any level of software for testing and is preferably a good technique to use first. In this technique,
only one condition to be tested from each partition. Because we assume that, all the conditions in
one partition behave in the same manner by the software. In a partition, if one condition works
11. 11 | P a g e B y G u r p r e e t
S i n g h
http://gsbprogramming.blogspot.in/
other will definitely work. Likewise we assume that, if one of the condition does not work then
none of the conditions in that partition will work.
Equivalence partitioning is a testing technique where input values set into classes for testing.
Valid Input Class = Keeps all valid inputs.
Invalid Input Class = Keeps all Invalid inputs.
Boundary Value Analysis
It’s widely recognized that input values at the extreme ends of input domain cause more errors in
system. More application errors occur at the boundaries of input domain. ‘Boundary value
analysis’ testing technique is used to identify errors at boundaries rather than finding those exist
in center of input domain.
Boundary value analysis is a next part of Equivalence partitioning for designing test cases where
test cases are selected at the edges of the equivalence classes.
Boundary value analysis is often called as a part of stress and negative testing. Boundary value
analysis is a test case design technique to test boundary value between partitions (both valid
boundary partition and invalid boundary partition). A boundary value is an input or output value
on the border of an equivalence partition, includes minimum and maximum values at inside and
outside boundaries.
Using Boundary Value Analysis technique tester creates test cases for required input field. For
example; an Address text box which allows maximum 500 characters. So, writing test cases for
each character once will be very difficult so that will choose boundary value analysis.
