Abstract:
Many teams struggle with fitting in testing activities inside of a Sprint. They end up doing primarily development activities in a Sprint and push testing activities to run in dedicated testing Sprints following the coding Sprints or have a coding and testing Sprint running in parallel. However, in Scrum, the output of every Sprint is a potentially shippable product increment. This means the product increment should be well tested within the Sprint and ready to be delivered. Come to this presentation to learn how to tackle testing on an Agile team, what kind of tests to execute, what to automate and what not to automate, the different test responsibilities, and when to run which tests. Leave with a testing strategy that you can start applying the next day to gradually get a team to start testing from day 1 of the Sprint and deliver a true product increment at the end of each Sprint.

Storyboarding is a visual technique used in software requirements engineering to help understand user needs and system functionality. It involves creating a series of illustrations that show how a user will interact with a proposed system. Storyboards have benefits like communicating design ideas clearly and allowing feedback before development. Prototyping creates a mock-up of a proposed system to help validate requirements with users. Use cases are written descriptions of how users will perform tasks with a system. They define the actors, scenarios, and goals to help specify requirements.

Algorithm ExampleFor the following taskUse the random module .docxdaniahendric
Algorithm Example
For the following task:
Use the random module to write a number guessing game.
The number the computer chooses should change each time you run the program.
Repeatedly ask the user for a number. If the number is different from the computer's let the user know if they guessed too high or too low. If the number matches the computer's, the user wins.
Keep track of the number of tries it takes the user to guess it.
An appropriate algorithm might be:
Import the random module
Display a welcome message to the user
Choose a random number between 1 and 100
Get a guess from the user
Set a number of tries to 0
As long as their guess isn’t the number
Check if guess is lower than computer
If so, print a lower message.
Otherwise, is it higher?
If so, print a higher message.
Get another guess
Increment the tries
Repeat
When they guess the computer's number, display the number and their tries count
Notice that each line in the algorithm corresponds to roughly a line of code in Python, but there is no coding itself in the algorithm. Rather the algorithm lays out what needs to happen step by step to achieve the program.

I. INTRODUCTION
Object-oriented design and development are popular concepts in today’s software development
environment. They are often heralded as the silver bullet for solving software problems. While
in reality there is no silver bullet, object-oriented development has proved its value for systems
that must be maintained and modified. Object-oriented software development requires a
different approach from more traditional functional decomposition and data flow development
methods. This includes the software metrics used to evaluate object-oriented software.
The concepts of software metrics are well established, and many metrics relating to product
quality have been developed and used. With object-oriented analysis and design methodologies
gaining popularity, it is time to start investigating object-oriented metrics with respect to
software quality. We are interested in the answer to the following questions:
• What concepts and structures in object-oriented design affect the quality of the
software?
• Can traditional metrics measure the critical object-oriented structures?
• If so, are the threshold values for the metrics the same for object-oriented designs as for
functional/data designs?
• Which of the many new metrics found in the literature are useful to measure the critical
concepts of object-oriented structures?

Abstract- This paper proposes a new technique in the
domain of Agent oriented software engineering. Agents
work in autonomous environments and can respond to
agent triggers. Agents can be very useful in requirement
analysis phase of software development process, where
they can react towards the requirement triggers and
result in aligned notations to identify the best possible
design solution from existing designs. Agent helps in
design generation process, which includes the use of
Artificial intelligence. The results produced clearly
shows the improvements over the conventional
reusability principles and ideas.
1. INTRODUCTION
Agent oriented software engineering is a new
emerging technique which is growing very
rapidly. Software development industries have
invested huge efforts in this domain and results
published by many of them are very exiting [1].
The autonomous and reactive nature of agents
makes it possible for the designers to visualize
in terms of real life problem solving scenarios
where socio-logical [2] characteristics of agents
automatically activate the timely checks for any
problem in domain and to solve the same using
agents.
Agents are very helpful in the software
development life cycle. Experiments carried out
in past have shown [2][9][10] the improvement
in the SDLC and conclusion is that agents can be
very helpful in cost and effort minimization; if
tuned properly. Fine-tuning of agents and SDLC
process-state-plug-in for two-way
communications results in agent based software
development process where intelligent agents
will take decisions for better time and resource
utilization.
Fine-tuning of agents and SDLC process-state-
plug-in for two-way communications results in
agent based software development process
where intelligent agents will take decisions for
better time and resource utilization. Agents are
capable of storing historic data, which helps in
decision-making using heuristic based approach.
This paper discusses the details of one such
experiment conducted to improve the
requirement analysis process with the help of
proactive agents. Agents automatically sense the
requirement environment and propose their own
set of important requirement checklist. This is
sort of intelligent assistance with domain
heuristic, which leads to cover all possible
requirement entities of the problem domain.

Dandelion Hashtable: beyond billion requests per second on a commodity serverAntonios Katsarakis
This slide deck presents DLHT, a concurrent in-memory hashtable. Despite efforts to optimize hashtables, that go as far as sacrificing core functionality, state-of-the-art designs still incur multiple memory accesses per request and block request processing in three cases. First, most hashtables block while waiting for data to be retrieved from memory. Second, open-addressing designs, which represent the current state-of-the-art, either cannot free index slots on deletes or must block all requests to do so. Third, index resizes block every request until all objects are copied to the new index. Defying folklore wisdom, DLHT forgoes open-addressing and adopts a fully-featured and memory-aware closed-addressing design based on bounded cache-line-chaining. This design offers lock-free index operations and deletes that free slots instantly, (2) completes most requests with a single memory access, (3) utilizes software prefetching to hide memory latencies, and (4) employs a novel non-blocking and parallel resizing. In a commodity server and a memory-resident workload, DLHT surpasses 1.6B requests per second and provides 3.5x (12x) the throughput of the state-of-the-art closed-addressing (open-addressing) resizable hashtable on Gets (Deletes).

zkStudyClub - LatticeFold: A Lattice-based Folding Scheme and its Application...Alex Pruden
Folding is a recent technique for building efficient recursive SNARKs. Several elegant folding protocols have been proposed, such as Nova, Supernova, Hypernova, Protostar, and others. However, all of them rely on an additively homomorphic commitment scheme based on discrete log, and are therefore not post-quantum secure. In this work we present LatticeFold, the first lattice-based folding protocol based on the Module SIS problem. This folding protocol naturally leads to an efficient recursive lattice-based SNARK and an efficient PCD scheme. LatticeFold supports folding low-degree relations, such as R1CS, as well as high-degree relations, such as CCS. The key challenge is to construct a secure folding protocol that works with the Ajtai commitment scheme. The difficulty, is ensuring that extracted witnesses are low norm through many rounds of folding. We present a novel technique using the sumcheck protocol to ensure that extracted witnesses are always low norm no matter how many rounds of folding are used. Our evaluation of the final proof system suggests that it is as performant as Hypernova, while providing post-quantum security.

Essentials of Automations: Exploring Attributes & Automation ParametersSafe Software
Building automations in FME Flow can save time, money, and help businesses scale by eliminating data silos and providing data to stakeholders in real-time. One essential component to orchestrating complex automations is the use of attributes & automation parameters (both formerly known as “keys”). In fact, it’s unlikely you’ll ever build an Automation without using these components, but what exactly are they?
Attributes & automation parameters enable the automation author to pass data values from one automation component to the next. During this webinar, our FME Flow Specialists will cover leveraging the three types of these output attributes & parameters in FME Flow: Event, Custom, and Automation. As a bonus, they’ll also be making use of the Split-Merge Block functionality.
You’ll leave this webinar with a better understanding of how to maximize the potential of automations by making use of attributes & automation parameters, with the ultimate goal of setting your enterprise integration workflows up on autopilot.

Analyze User Stories and Epic
Applying requirements engineering techniques allows Agile teams to polish the user stories and epics, add context,
consider impacts and dependencies, and identify any gaps, such as missing non-functional requirements.
Although the majority of the requirements engineering techniques come from traditional development approaches,
they are also effective in Agile development.
Generally, in traditional projects, requirements engineering activities and techniques are formalized, performed
sequentially, and are the responsibility of designated people such as Business Analysts, Functional Analysts,
Technical Architects, Enterprise Architects, and Process Analysts.
As a tester, to be able to assist in clarifying (and possibly improving) user stories, epics, and other Agile
requirements, it is necessary to know, understand, select and use the various requirements engineering techniques
that support this.
Example of such techniques are storyboards, story mapping, personas, diagrams, and use cases.

Analyze User Stories and Epic
Storyboards: A Storyboard (not to be confused with Agile task board or Agile user story board) provides a visual
representation of the system. Storyboards help testers to:
See the thought process behind the user stories, and the overall “story”, providing context, making it possible
to quickly see the functional flow of the system and identify any gaps in the logic.
Visualize groups of user stories related to a common area of the system (Themes) which can be considered for
inclusion in the same iteration, as they will likely be touching the same piece of code.
Assist in Story Mapping and prioritization of epics and related user stories in the product backlog.
Assist with identifying acceptance criteria for user stories and epics.
Assist with selecting the right test approach based on the visual aspect on the system design.
Along with Story Mapping, assist in prioritizing tests and in identifying needs for stubs, drivers and/or mocks.

Analyze User Stories and Epic
Story Mapping: Story Mapping (or user story Mapping) is a technique which consists of using 2 independent
dimensions to order user stories. The horizontal axis of the map represents the order of priority of each of the user
stories, whilst the vertical axis represents the sophistication of the implementation. Use of Story Mapping can help
testers to:
Determine the most basic functionalities of a system to distillate a smoke test.
Identify the order of functionalities to determine test priorities.
Visualize the scope of the system.
Determine the risk level of each user story.
Personas: Personas are used to define fictional characters or archetypes that illustrate how typical users will
interact with the system. Use of personas can help testers to:
Identify gaps in user stories by identifying different types of users that may use the system.
Identify inconsistencies in user stories on how a particular type of user may use the system compared to others.
Elicitate user story acceptance criteria
Discover additional test paths during exploratory testing
Reveal test conditions, especially those related to particular user group

Analyze User Stories and Epic
Diagrams: Diagrams such as entity relationship diagrams, class diagrams, and (other) UML diagrams can show the
structure or flow of data and the functional attributes or behavior of the system, and may be used to identify gaps
in system functionality.
Use Cases: Use Cases (diagrams and specifications) can assist testers to:
Ensure user stories are testable and properly sized.
Determine whether the user stories need to be refined or decomposed.
Reveal forgotten stakeholders.
Identify interfaces and integration points, which should be considered during test design.
See the relationships between epics and user stories, to check that the epic doesn’t have any missing user
stories.

Identifying Acceptance Criteria
Requirements engineering is a process consisting of the following steps:
Elicitation: The process of discovering, understanding, documenting, and reviewing the users’ needs and
constraints for the system. Elicitation techniques should be used to derive, evaluate and enhance the
acceptance criteria.
Documentation: The process of documenting the users’ needs and constraints clearly and precisely. User
stories and acceptance criteria should be documented to level corresponding to the team adherence over the
principles of the Agile manifesto. The type of documentation depends on the team’s and stakeholders’
approach. Acceptance criteria can be documented using natural language, using models (e.g., state transition
diagrams) or using examples.
Negotiation and Validation: For every user story, multiple stakeholders might have other insights or
preferences. As these insights and preferences might be inconsistent or even conflicting, so can each
stakeholder’s acceptance criteria. Each of these conflicts should be identified, negotiated, and resolved
between all impacted stakeholders. Every forgotten or non-resolved conflict might endanger the success of the
project. At the end of this step, the content of each user story is validated by the impacted stakeholders (e.g.
as a Definition of Ready).
Management: As projects progress, opinions and circumstances might change. Even though acceptance criteria
were properly elicited, documented, negotiated, and validated, acceptance criteria are still subject to
change. Because of the potential for changes, user stories should be managed by using good configuration and
change management processes.

Identifying Acceptance Criteria
For identifying acceptance criteria, multiple elicitation techniques are at the disposal of the tester, including the
following:
Quantitative Questionnaires: Using quantitative data culled from closed-ended questions is an excellent way of
making clear comparisons between various data points. This will often provide numerical data that can be included in
a numerical conclusion for an acceptance criterion. Best used for large number of stakeholders
Qualitative Questionnaires: Open-ended questions are an extremely effective way to add more quality to
quantitative research. Open-ends are best used as a follow-up to key questions. This could generate additional
information for which new User Stories have to created or has to be added to existing ones. Best used for small
number of stakeholders
Qualitative Interview: The qualitative interview is more flexible than a quantitative query and is mainly used to
acquire information about backgrounds, contexts and causes. It is unlikely to return hard data, but acceptance criteria
can be derived from the responses regarding the context of a user story. The qualitative interview can be the follow-
up of any type of questionnaire, to deepen the derived acceptance criteria.

Identifying Acceptance Criteria
Multiple other elicitation techniques exist, in the range of observation techniques (e.g. apprenticing), creativity
techniques (e.g. 6 Thinking hats) and supporting techniques (e.g. low-fi prototyping). The technique toolset of the
tester will influence the quality of the elicitated acceptance criteria.
