1. The document discusses the objectives and principles of software testing. It defines testing as a process that evaluates the products and work related to software development, including both static and dynamic testing.
2. Testing aims to find defects, improve quality and confidence, and prevent defects from making it to production. While testing can show bugs exist, it cannot prove that no bugs remain since testing can only evaluate a finite set of cases.
3. The testing process is compared to a driving test, where the tester evaluates if the software satisfies requirements and is fit for purpose, similar to how an examiner evaluates a driver.
Simulation involves mathematically imitating real-world situations to study their properties and operating characteristics. The simulation process involves 11 steps: problem formulation, setting objectives, model conceptualization, data collection, model translation, verification, validation, experimental design, production runs and analysis, documentation, and implementation. Simulation offers advantages like flexibility to model complex systems, ability to study interactions of variables, perform "what if" analyses, and compress time without interfering with real systems. Simulation has applications in manufacturing, construction, military, logistics, transportation, education, business, healthcare, and networking.
1) Random numbers are used as inputs to simulation models and are generated using pseudo-random number generators like the linear congruential method. 2) Conceptual modeling involves describing the problem, inputs, outputs, components and their interactions of the system being modeled in a non-software specific way. 3) Data collection and simplification are important parts of conceptual modeling to develop the simulation model in a faster and more accurate manner.
The document outlines the seven stages of the software development process: analysis, design, implementation, testing, documentation, evaluation, and maintenance. It focuses on the analysis stage, explaining that analysts must understand the problem by interviewing clients, developing a software specification that clearly defines the problem and serves as a legal agreement between the analyst and client. Examples of questions analysts ask clients to determine program requirements like input/output details are provided.
A spreadsheet cell-meaning model for testing - Daniel Kulesz at Sems 2014semsworkshop
This document presents a new cell-meaning model for spreadsheet testing. The current "naive" model of classifying cells as input, intermediate, or output is too limited.

Assignment 2:
Creating a Use Case
Introduction
With this paper I will show how a use case diagram should be used. I base this paper from fig. 3
– 11 pages 78 – 80 in our textbook titled: System Analysis and Design in a Changing World, 6th
edition, by Satzinger, Jackson, and Burd. In the Use Case Diagram that I make, I will depict a
use case for a RMO CSMS subsystem. I will also be describing the overview of the diagram. I
will also provide an analysis of the characters.
Use Case Introduction
An activity that a system performs is known as a use case. It is mostly in response to the
user. Use case analysis is a technique that is used for identifying the functional requirements of
the software system. A use case is to designate the point of view from a client and customer, this
is a use cases main purpose. An analytical role in the development process is done by the
developer. The other definition of a use case is as an objective or as an actor. Actors are with a
particular system and they want to achieve. In the use case diagram that I create, I will show the
actors and use cases for the RMO CSMS subsystem for marketing.
Marketing Subsystem
RMO CSMS
Marketing Merchandising
Overview
The overview of this use case diagram has the following: It shows the system boundary,
the association and the actors. The one that does the interaction with the system by entering or
receiving data is called a group, actor, external agent or person. Another part of the whole system
are the system boundaries. System boundaries are the computerized part of the application along
with the users who operate it. When a customer places a relationship between certain things such
as a certain employee in a department and an order, this would be a logical association. In my
diagram I have included two actors, one is representing marketing and the other represents

The events and actions that define the interactions with a system and the role in order to
be able to discover a goal is a list of actions or steps in an event in a use case. The elements that
make up a use case diagram and the connections that are between a use case and the actors is an
association. This lets us know that there is communication between the actors and the use case.
On the marketing side they need to be able to update / add promotions, production and business
partners. On the merchandising side they need to be able to update / add production information

LF Energy Webinar: Carbon Data Specifications: Mechanisms to Improve Data Acc...DanBrown980551
This LF Energy webinar took place June 20, 2024. It featured:
-Alex Thornton, LF Energy
-Hallie Cramer, Google
-Daniel Roesler, UtilityAPI
-Henry Richardson, WattTime
In response to the urgency and scale required to effectively address climate change, open source solutions offer significant potential for driving innovation and progress. Currently, there is a growing demand for standardization and interoperability in energy data and modeling. Open source standards and specifications within the energy sector can also alleviate challenges associated with data fragmentation, transparency, and accessibility. At the same time, it is crucial to consider privacy and security concerns throughout the development of open source platforms.
This webinar will delve into the motivations behind establishing LF Energy’s Carbon Data Specification Consortium. It will provide an overview of the draft specifications and the ongoing progress made by the respective working groups.
Three primary specifications will be discussed:
-Discovery and client registration, emphasizing transparent processes and secure and private access
-Customer data, centering around customer tariffs, bills, energy usage, and full consumption disclosure
-Power systems data, focusing on grid data, inclusive of transmission and distribution networks, generation, intergrid power flows, and market settlement data
Elasticity vs. State? Exploring Kafka Streams Cassandra State StoreScyllaDB
kafka-streams-cassandra-state-store' is a drop-in Kafka Streams State Store implementation that persists data to Apache Cassandra.
By moving the state to an external datastore the stateful streams app (from a deployment point of view) effectively becomes stateless. This greatly improves elasticity and allows for fluent CI/CD (rolling upgrades, security patching, pod eviction, ...).
It also can also help to reduce failure recovery and rebalancing downtimes, with demos showing sporty 100ms rebalancing downtimes for your stateful Kafka Streams application, no matter the size of the application’s state.
As a bonus accessing Cassandra State Stores via 'Interactive Queries' (e.g. exposing via REST API) is simple and efficient since there's no need for an RPC layer proxying and fanning out requests to all instances of your streams application.
Lee Barnes - Path to Becoming an Effective Test Automation Engineer.pdfleebarnesutopia
So… you want to become a Test Automation Engineer (or hire and develop one)? While there’s quite a bit of information available about important technical and tool skills to master, there’s not enough discussion around the path to becoming an effective Test Automation Engineer that knows how to add VALUE. In my experience this had led to a proliferation of engineers who are proficient with tools and building frameworks but have skill and knowledge gaps, especially in software testing, that reduce the value they deliver with test automation.
In this talk, Lee will share his lessons learned from over 30 years of working with, and mentoring, hundreds of Test Automation Engineers. Whether you’re looking to get started in test automation or just want to improve your trade, this talk will give you a solid foundation and roadmap for ensuring your test automation efforts continuously add value. This talk is equally valuable for both aspiring Test Automation Engineers and those managing them! All attendees will take away a set of key foundational knowledge and a high-level learning path for leveling up test automation skills and ensuring they add value to their organizations.

TrustArc Webinar - Your Guide for Smooth Cross-Border Data Transfers and Glob...TrustArc
Global data transfers can be tricky due to different regulations and individual protections in each country. Sharing data with vendors has become such a normal part of business operations that some may not even realize they’re conducting a cross-border data transfer!
The Global CBPR Forum launched the new Global Cross-Border Privacy Rules framework in May 2024 to ensure that privacy compliance and regulatory differences across participating jurisdictions do not block a business's ability to deliver its products and services worldwide.
To benefit consumers and businesses, Global CBPRs promote trust and accountability while moving toward a future where consumer privacy is honored and data can be transferred responsibly across borders.
This webinar will review:
- What is a data transfer and its related risks
- How to manage and mitigate your data transfer risks
- How do different data transfer mechanisms like the EU-US DPF and Global CBPR benefit your business globally
- Globally what are the cross-border data transfer regulations and guidelines

2. Scenario Dar Es Salaam High School has recently been formed by joining together six smaller schools. The head teacher wants to have a modern ICT system to administer staff and student records. She has decided to employ a systems analyst to look at the existing systems and recommend a new system. The system will need to produce hundreds of reports in one session and should be able to find individual records very quickly. Using the results of the analysis of the current system the analyst will need to design the new system. Once the system has been designed and developed, user and technical documentation will need to be produced.
3. Question 6a Other than observation, describe the methods that the systems analyst could use to research the current systems.
4. Answer 6a Distribute/Hand out written questionnaires to system users (to complete) Interview current system users face to face Examining documents used in the current system
5. Examiner Feedback The answers provided were generally vague descriptions with little reference to teachers and the school. It is surprising to see that despite teachers being the focal point of this scenario as being the ‘system users’ candidates often referred to ‘workers’ or ‘employees’ thereby implying that everybody would be interviewed or given questionnaires rather than the staff concerned. Some candidates were able to answer the question well.
6. Question 6b Describe four different items that the systems analyst will need to include at the design stage. Using the scenario of Dar Es Salaam High School, explain the factors that will influence the choice of each item
8. Examiners Report Candidates were able to score highly on the part of the question which asked for items of design but, despite being told in the question to refer to the scenario, candidates frequently gave general answers not related specifically to the scenario when explaining the factors.
10. Answer 7a Two from: Produced specifically for systems analysts/programmers. Helps when the system needs further development/upgrading/improvements. Helpful should any errors occur in the system and system needs amending to get rid of these error
11. Examiners Feedback This was the part of the question which most candidates found straightforward with many scoring high marks.
12. Question 7b Describe the two types of technical documentation including details of the contents of each one
13. Answer 7b Eight from: Systems documentation.... ....provides a detailed overview of the whole system. Test data/test plans so that systems analyst can see the results of these/test results. Can use this data again to check if errors have been successfully removed. The results of the systems analysis/DFD diagrams. What is expected of the system/purpose of the system. Overall design decisions such as the choice of hardware and software/file, input and output structures. Systems flowcharts.
14. Answer (cont) Program documentation.... ....produced for program code that has been written. Description of the software/purpose of the software. Reasons for choosing those pieces of existing software that were used… ….. instead of the programmer having to write code. Input and output data formats. Program flowcharts/algorithms. Program listing – this will be a complete copy of the code used… …and annotation explaining what each module of code does. Notes that will help any future programmer to make modifications to the system
15. Examiners feedback This part of the question enabled candidates to score some marks with many getting quite high marks. It was, however, the question which was left unanswered by a substantial number of candidates.
16. Question 7c After the system has been developed it will be evaluated. Describe how test results are recorded and explain how they affect this evaluation
17. Answer 7b Three from: (A table) showing the type of test, test data, expected results, actual results and a comment on the results. (One mark for three column headings, two marks for 5 column headings.) Test results will help the systems analyst to make judgements. Comparison will be made of the actual results with the expected results. If the results are not as expected system will need to refined. Comments in the comparison table contribute to the evaluation
18. Examiners feedback Candidates found this the hardest question on the paper. Many were unable to visualise what a test plan would look like and instead concentrated on answering as if this was a question about types of test data with descriptions of normal/live and abnormal/extreme data
