Testing is needed to identify defects, provide confidence, and prevent defects. The objectives of testing include finding defects, providing information, and achieving confidence. Exhaustive testing is impossible, so risk-based testing is used instead of testing all combinations of inputs. Testing activities should start early in the software development life cycle and focus on defined objectives. Defect clusters are used to plan risk-based tests and test cases are regularly revised to overcome the pesticide paradox. The fundamental test process includes test planning, analysis and design, implementation and execution, evaluation and reporting, and closure activities. Independence is important for testing to provide an objective perspective.

Negative testing is all about ensuring that a product or application under test does NOT fail when an unexpected input is being fed. The purpose of Negative testing is to break the system and to verify the application response during unintentional inputs.
Basically this slid will help to Learn software quality testing on scratch level.
Software testing is the quality measures conducted to provide stakeholders with information about the quality of the product or service. Test techniques include, but are not limited to, the process of executing a program or application with the intent of finding software bugs. It is an important part of the entire Software Development ensuring that the functionalities of the system are tested to the finest and assures the quality, correctness and completeness of the product. Software testing, depending on the testing method employed, can be implemented at any time in the development process.
Stages of testing:
o Test planning
o Test Analysis
o Test verification & Construction
o Test execution
o Defect tracking and management
o Quality Analysis Bug tracking
o Report
o Final testing & implementation

June 3, 2024 Anti-Semitism Letter Sent to MIT President Kornbluth and MIT Cor...Levi Shapiro
Letter from the Congress of the United States regarding Anti-Semitism sent June 3rd to MIT President Sally Kornbluth, MIT Corp Chair, Mark Gorenberg
Dear Dr. Kornbluth and Mr. Gorenberg,
The US House of Representatives is deeply concerned by ongoing and pervasive acts of antisemitic
harassment and intimidation at the Massachusetts Institute of Technology (MIT). Failing to act decisively to ensure a safe learning environment for all students would be a grave dereliction of your responsibilities as President of MIT and Chair of the MIT Corporation.
This Congress will not stand idly by and allow an environment hostile to Jewish students to persist. The House believes that your institution is in violation of Title VI of the Civil Rights Act, and the inability or
unwillingness to rectify this violation through action requires accountability.
Postsecondary education is a unique opportunity for students to learn and have their ideas and beliefs challenged. However, universities receiving hundreds of millions of federal funds annually have denied
students that opportunity and have been hijacked to become venues for the promotion of terrorism, antisemitic harassment and intimidation, unlawful encampments, and in some cases, assaults and riots.
The House of Representatives will not countenance the use of federal funds to indoctrinate students into hateful, antisemitic, anti-American supporters of terrorism. Investigations into campus antisemitism by the Committee on Education and the Workforce and the Committee on Ways and Means have been expanded into a Congress-wide probe across all relevant jurisdictions to address this national crisis. The undersigned Committees will conduct oversight into the use of federal funds at MIT and its learning environment under authorities granted to each Committee.
• The Committee on Education and the Workforce has been investigating your institution since December 7, 2023. The Committee has broad jurisdiction over postsecondary education, including its compliance with Title VI of the Civil Rights Act, campus safety concerns over disruptions to the learning environment, and the awarding of federal student aid under the Higher Education Act.
• The Committee on Oversight and Accountability is investigating the sources of funding and other support flowing to groups espousing pro-Hamas propaganda and engaged in antisemitic harassment and intimidation of students. The Committee on Oversight and Accountability is the principal oversight committee of the US House of Representatives and has broad authority to investigate “any matter” at “any time” under House Rule X.
• The Committee on Ways and Means has been investigating several universities since November 15, 2023, when the Committee held a hearing entitled From Ivory Towers to Dark Corners: Investigating the Nexus Between Antisemitism, Tax-Exempt Universities, and Terror Financing. The Committee followed the hearing with letters to those institutions on January 10, 202

2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.

Embracing GenAI - A Strategic ImperativePeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.
The French Revolution, which began in 1789, was a period of radical social and political upheaval in France. It marked the decline of absolute monarchies, the rise of secular and democratic republics, and the eventual rise of Napoleon Bonaparte. This revolutionary period is crucial in understanding the transition from feudalism to modernity in Europe.

2. THE FUNDAMENTALS OF TESTING:
why testing is needed ?
its limitations, objectives and purpose;
the principles behind testing
the process that testers follow;
some of the psychological factors that testers must consider in their work.
3. why testing is needed ?
Software systems context
• Testing Principle - Testing is context dependent Testing
is done differently in different contexts. For example,
safety-critical software is tested differently from an e-
commerce site
4. why testing is needed ?
Causes of software defects
Do our mistakes matter?
• Let's think about the consequences of mistakes. We agree that any human being, programmers and testers included, can make an error. These
errors may produce defects in the software code or system, or in a document. If a defect in code is executed, the system may experience a failure. So
the mistakes we make matter partly because they have consequences for the products for which we are responsible.
When do defects arise?
• In Figure 1.1 we can see how defects may arise in four requirements for a product. We can see that requirement 1 is implemented correctly - we
understood the customer's requirement, designed correctly to meet that requirement, built correctly to meet the design, and so deliver that
requirement with the right attributes: functionally, it does what it is supposed to do and it also has the right non-functional attributes, so it is fast
enough, easy to understand and so on.
What is the cost of defects?
• As well as considering the impact of failures arising from defects we have not found, we need to consider the impact of when we find those defects.
The cost of finding and fixing defects rises considerably across the life cycle; think of the old English proverb 'a stitch in time saves nine'. This means
that if you mend a tear in your sleeve now while it is small, it's easy to mend, but if you leave it, it will get worse and need more stitches to mend it.
5. FIGURE 1.1 WE CAN SEE HOW DEFECTS MAY ARISE IN FOUR REQUIREMENTS FOR A PRODUCT.
why testing is needed ?
6. ROLE OF TESTING IN SOFTWARE DEVELOPMENT,
MAINTENANCE AND OPERATIONS
We have seen that human errors can cause a defect or fault to be introduced at any
stage within the software development life cycle and, depending upon the
consequences of the mistake, the results can be trivial or catastrophic. Rigorous
testing is necessary during development and maintenance to identify defects, in order
to reduce failures in the operational environment and increase the quality of the
operational system. This includes looking for places in the user interface where a user
might make a mistake in input of data or in the interpretation of the output, and
looking for potential weak points for intentional and malicious attack. Executing tests
helps us move towards improved quality of product and service, but that is just one of
the verification and validation methods applied to products. Processes are also
checked, for example by audit. A variety of methods may be used to check work, some
of which are done by the author of the work and some by others to get an
independent view.
why testing is needed ?
7. TESTING AND QUALITY
What is quality?
• Projects aim to deliver software to specification. For the project to deliver what the customer needs requires a correct specification. Additionally, the
delivered system must meet the specification. This is known as validation ('is this the right specification?') and verification ('is the system correct to
specification?'). Of course, as well as wanting the right software system built correctly, the customer wants the project to be within budget and
timescale - it should arrive when they need it and not cost too much.
What is root cause analysis?
• When we detect failures, we might try to track them back to their root cause, the real reason that they happened. There are several ways of carrying
out root cause analysis, often involving a group brainstorming ideas and discussing them, so you may see different techniques in different
organizations. If you are interested in using root cause analysis in your work, you'll find simple techniques described in [Evans], [TQMI] and [Robson].
For example, suppose an organization has a problem with printing repeatedly failing. Some IT maintenance folk get together to examine the
problem and they start by brainstorming all the possible causes of the failures. Then they group them into categories they have chosen, and see if
there are common underlying or root causes.
why testing is needed ?
8. HOW MUCH TESTING IS ENOUGH?
Testing Principle - Exhaustive testing is impossible
Testing everything (all combinations of inputs and preconditions) is not feasible
except for trivial cases. Instead of exhaustive testing, we use risks and priorities to
focus testing efforts.

COMMON OBJECTIVES OF TESTING. WE'LL
EXPLAIN HOW TESTING HELPS US TO FIND
DEFECTS, PROVIDE CONFIDENCE AND
INFORMATION, AND PREVENT DEFECTS. WE
WILL ALSO INTRODUCE ADDITIONAL
FUNDAMENTAL PRINCIPLES OF TESTING.
WHAT IS TESTING?
10. WHAT IS TESTING?
The driving test - an analogy for software testing
• We have spent some time describing why we need to test, but we have not discussed what testing is. What
do we mean by the word testing? We use the words test and testing in everyday life and earlier we said
testing could be described as 'checking the software is OK'
Defining software testing
• With that analogy in mind, let's look at the ISTQB definition of software testing.
Software test and driving test compared
• We can see that the software test is very like a driving test in many ways, although of course it is not a
perfect analogy! The driving examiner becomes the software tester. The driver being examined becomes the
system or software under test, and you'll see as we go through this book that the same approach broadly
holds.
11. When can we meet our test objectives?
•Testing activities should start as early as possible in the software or system development life cycle and should be focused on defined
objectives.
Focusing on defects can help us plan our tests
•Reviewing defects and failures in order to improve processes allows us to improve our testing and our requirements, design and development
processes. One phenomenon that many testers have observed is that defects tend to cluster. This can happen because an area of the code is
particularly complex and tricky, or because changing software and other products tends to cause knock-on defects. Testers will often use this
information when making their risk assessment for planning the tests, and will focus on known 'hot spots'.
The defect clusters change over time
•If the same tests are repeated over and over again, eventually the same set of test cases will no longer find any new bugs. To overcome this
'pesticide paradox', the test cases need to be regularly reviewed and revised, and new and different tests need to be written to exercise
different parts of the software or system to potentially find more defects.

14. THE PSYCHOLOGY OF
TESTING
Independent testing - who is a tester?
• The mindset we want to use while testing and reviewing is
different from the one we use while analyzing or developing.
2.Why do we sometimes not get on with the rest
of the team?
• As well as independence, separation of the tester role from the developer
role is also done to help focus effort and to provide the benefits of trained
and professional testing resources. In many organizations, earlier stages of
testing are carried out by the developers and integrators and later stages
independently, either by a specialist test group or by the customers.
