SO WHAT IS “NEGATIVE” TESTING ANYWAY?
GOALS OF NEGATIVE TESTING
NEGATIVE TESTING PROCESS
ADVANTAGES OF NEGATIVE TESTING
WHEN TO STOP NEGATIVE TESTING?
Why you cannot ignore negative testing?
Testing may show the defects are present, but cannot prove that there are no defects. After testing the system or product thoroughly we cannot say that the product is complete defect free. Testing always reduces the no of undiscovered defects remaining in the software.
In order to plan for automated or manual regression test execution, it's always efficient in the long run to prepare your regression testing framework. This paper presents a simple framework which can be followed on systems with any level of complexity.

False positives: automated testing’s arch nemesis.
When automated tests are written well, they are part of a healthy CI/CD process that can save developer time and company money. But when a team gets false positives from unreliable tests, the entire build can get derailed. What’s worse, too many false positives can erode an organization's belief in the value of using a test automation framework at all.
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.

Developing a web or mobile application takes a lot of effort, but all that effort can go down the drain quickly if you improperly load test the application or completely skip testing. Load testing applications is important and a necessary step in the pre-production stage.
New applications, ones that have not yet made it to the production stage, likely don’t have a performance benchmark established. You don’t typically know what to expect with a new app, which is why before you do a larger load test on any application you first do some baseline testing. This will allow you to establish some benchmarks and pick out any performance issues before you place a larger load on the app. For example, if your app crashes with just five users, you have a problem. Look to the application architects to determine if any service level agreements have been set for the application during design.
Once you have done some baseline testing you are ready to load test your application to determine its performance levels under heavier load. Here are 5 essential tips for starting load testing on an application.

TEST CASE PRIORITIZATION FOR OPTIMIZING A REGRESSION TESTijfcstjournal
Regression testing makes sure that upgradation of software in terms of adding new features or for bug
fixing purposes should not hamper previously working functionalities. Whenever a software is upgraded or
modified, a set of test cases are run on each of its functions to assure that the change to that function is not
affecting other parts of the software that were previously running flawlessly. For achieving this, all existing
test cases need to run as well as new test cases might be required to be created. It is not feasible to reexecute
every test case for all the functions of a given software, because if there is a large number of test
cases to be run, then a lot of time and effort would be required. This problem can be addressed by
prioritizing test cases. Test case prioritization technique reorders the priority in which test cases are
implemented, in an attempt to ensure that maximum faults are uncovered early on by the high priority test
cases implemented first. In this paper we propose an optimized test case prioritization technique using Ant
Colony Optimization (ACO) to reduce the cost, effort and time taken to perform regression testing and also
uncover maximum faults. Comparison of different techniques such as Retest All, Test Case Minimization,
Test Case Prioritization, Random Test Case Selection and Test Case Prioritization using ACO is also
depicted.

RCA on Residual defects – Techniques for adaptive Regression testingIndium Software
One of the important issues associated with a system lifespan view that we have ignored in past
years is the effects of enduring defects – defects that persist undetected – across several
releases of a system. Many studies performed to date have evaluated regression testing
techniques under the limited context such as short term assessment which do not fully account
for the industry based solutions.
Reports estimate that regression testing consumes as much as 80% of the overall testing
budget and can consume up to 50% of the cost of software maintenance.

Summary.
Agile software development is probably the most common methodology used by organizations today, as such; many people have started to ask more and more questions about this methodology that sometimes based on wrong assumptions.
In this presentation, I will review the most common Myths and Misconceptions that I encounter during agile training courses, hopefully, to help people to divide the truth from the assumptions.
The scrum master role contains many theoretical descriptions that do not provide an answer to the basic question of “What is the Day to Day activities of the scrum master?”
In this presentation, I will provide a short checklist that will try to answer that basic question while examining few of the main ceremonies and artifacts of the Scrum framework.
Expectations of scrum masters - How to choose a true great scrum master?David Tzemach
In Scrum, the Scrum Master (SM) owns the responsibility for the process. During his day-to-day activities, the Scrum Master must ensure the team is following the Scrum Spirit, process, and the different practices of this the scrum framework.
Selecting a Scrum team’s Scrum Master can be the difference between success or failure of the team’s ability in adopting scrum. Therefore, it is highly important to ensure the selected Scrum Master has the current qualities, Skills, and characteristics. This will assist the team to adapt to the different challenges they will face while adapting the Scrum framework.
In order to assist one to determine the most suitable person lead the team as the Scrum Master, I have prepared a list of Characteristics, Skills, and qualities that a good Scrum Master should have in his armory.
Top 10 challenges faced by the scrum masterDavid Tzemach
The Role of the Scrum Master (SM) is very challenging. SM responsibilities include Coaching, Training and facilitating both Agile practices and Spirits. In this Presentation, I will review some of the challenges faced by the Scrum Master during his day-to-day activities.
In this presentation, we will review the fundamental concepts of Software Development Life Cycle (SDLC) and Software test life Cycle (STLC) throughout the traditional development methodologies.

Securing your Kubernetes cluster_ a step-by-step guide to success !KatiaHIMEUR1
Today, after several years of existence, an extremely active community and an ultra-dynamic ecosystem, Kubernetes has established itself as the de facto standard in container orchestration. Thanks to a wide range of managed services, it has never been so easy to set up a ready-to-use Kubernetes cluster.
However, this ease of use means that the subject of security in Kubernetes is often left for later, or even neglected. This exposes companies to significant risks.
In this talk, I'll show you step-by-step how to secure your Kubernetes cluster for greater peace of mind and reliability.
Elevating Tactical DDD Patterns Through Object CalisthenicsDorra BARTAGUIZ
After immersing yourself in the blue book and its red counterpart, attending DDD-focused conferences, and applying tactical patterns, you're left with a crucial question: How do I ensure my design is effective? Tactical patterns within Domain-Driven Design (DDD) serve as guiding principles for creating clear and manageable domain models. However, achieving success with these patterns requires additional guidance. Interestingly, we've observed that a set of constraints initially designed for training purposes remarkably aligns with effective pattern implementation, offering a more ‘mechanical’ approach. Let's explore together how Object Calisthenics can elevate the design of your tactical DDD patterns, offering concrete help for those venturing into DDD for the first time!

Observability Concepts EVERY Developer Should Know -- DeveloperWeek Europe.pdfPaige Cruz
Monitoring and observability aren’t traditionally found in software curriculums and many of us cobble this knowledge together from whatever vendor or ecosystem we were first introduced to and whatever is a part of your current company’s observability stack.
While the dev and ops silo continues to crumble….many organizations still relegate monitoring & observability as the purview of ops, infra and SRE teams. This is a mistake - achieving a highly observable system requires collaboration up and down the stack.
I, a former op, would like to extend an invitation to all application developers to join the observability party will share these foundational concepts to build on:

All you need to know about regression testing | David Tzemach
1. ALL YOU NEED TO
KNOW ABOUT
REGRESSION TESTING
DAVID TZEMACH
WWW.DTVISIONTECH.COM
JAN 23 2016
2. OVERVIEW
THE PROBLEM WE HAVE AS SOFTWARE TESTERS, IS THAT THE LIFE CYCLE OF
A SOFTWARE IS A VERY DYNAMIC. THEREFORE, EVERY PART IN CODE MAY
CHANGE AND LEAD TO A NEW RISKS THAT ALREADY REMOVED DURING THE
PREVIOUS TESTING CYCLES.
THE SOLUTION FOR OVERCOMING THIS PROBLEM IS TO USE THE TESTING
METHOD OF “REGRESSION TESTING” THAT PROVIDE A GREAT SOLUTION TO
HANDLE THESE NEW RISKS
3. DEFINITION OF “REGRESSION” TESTING
THE MOST SIMPLIFIED DEFINITION OF THIS TESTING METHOD, IS THAT WE
USE IT TO “VALIDATE A FUNCTIONALITY THAT WAS ALREADY WORKING AND
TESTED BY THE QA TEAM, STILL WORKS AFTER A NEW CODE THAT WAS
ADDED OR AN OLD CODE THAT WAS MODIFIED”
4. WHEN TO USE THIS TESTING METHOD..?
YOU SHOULD USE REGRESSION TESTS, WHENEVER YOU HAVE RISK THAT A SOFTWARE
THAT ALREADY TESTED MAY BE AFFECTED BY A NEW CODE THAT WERE
ADDED/CHANGED, EXAMPLES:
• A NEW FEATURE THAT WAS ADDED.
• BUG FIXES.
• CHANGES IN ORIGINAL REQUIREMENTS.
• NEW REQUIREMENTS ADDED.
• NEW PATCHES OR UPDATED.
6. PHASE 1: ANALYZE THE CHANGE
IN THIS PHASE YOU NEED TO ANALYZE HOW THE NEW CODE THAT WERE
ADDED/MODIFIED IS AFFECTING THE APPLICATION, TO ACCOMPLISH THIS TASK, PLEASE
ANSWER THIS BASIC QUESTION:
• HOW THIS CHANGE EFFECT PREDEFINED TESTS FOR THE ORIGINAL CODE?
• IS THERE ANY INTEGRATED CODE THAT IS AFFECTED BY THE CHANGE?
• WHICH AREAS ARE MOST LIKELY TO BE AFFECTED BY THE CHANGE?
• HOW THIS CHANGE EFFECT THE SOFTWARE DOCUMENTATION?
7. PHASE 2: THE TESTING STRATEGY
BASED ON THE RISK THAT YOU ANALYZED ON PHASE 1, YOU HAVE THE FULL INFORMATION THAT
YOU NEED TO DETERMINE WHAT IS THE TESTING EFFORT THAT YOU NEED TO REMOVE THE RISK:
TEST THE ENTIRE CODE - THIS STRATEGY IS THE BEST WHEN YOU HAVE THE TIME, MONEY AND
HIGHLY TRAINED AUTOMATION TEAM THAT ALLOWING YOU TO RUN THE ENTIRE TEST PLAN
INCLUDING THE OLD AND NEW TESTS.
TESTING DONE IN HIGH RISK AREAS- THIS STRATEGY WILL BE USED WHEN THE TESTING TEAM
IDENTIFIES THE AREAS THAT MOST LIKELY AFFECTED FROM THE CHANGE AND PROBABLY CONTAIN
THE BIGGER RISKS.
8. PHASE 3: HOW TO RUN YOUR TESTS?
THE TEST EXECUTION CAN BE ACCOMPLISHED IN 3 DIFFERENT WAYS:
MANUAL TESTS – MANUAL TESTERS WILL RUN THE SELECTED TESTS MANUALLY, BUT FOR ME, IT’S
THE LESS PREFERRED WAY TO HANDLE THIS TYPE OF TESTS.
AUTOMATED TEST - THIS IS MY PREFERRED WAY, ALL TESTS WILL RUN AUTOMATICALLY AND
WITHOUT A MAJOR INTERFERING OF THE MANUAL TESTERS.
AUTOMATION AND MANUAL TESTING – COMBINATION OF THE TWO WORLDS, OLD TESTS WILL BE
COVERED BY AUTOMATION, THE NEW TESTS WILL BE COVERED MANUALLY.
9. PHASE 4: REPORTING
THE TESTING RESULTS PER REGRESSION CYCLE SHOULD BE
REPORTED AND ANALYZED, ACCORDING TO FAILURES, WE CAN
ADD/REMOVE/MODIFY TESTS TO INCREASE THE EFFICIENCY OF
FUTURE TESTING CYCLE.
11. WHAT IS THE TESTING COVERAGE..?
WE ARE USING REGRESSION TESTS TO VALIDATE THAT NOTHING IS BROKEN
IN THE APPLICATION WHEN CODE MODIFICATIONS ARE DONE, THIS FACTOR
HAS A MAJOR EFFECT ON WHAT COVERAGE DO WE WANT TO HAVE,
SHOULD WE ADD EVERY TESTS TO THE REGRESSION CYCLES OR NARROW IT
TO A SPECIFIC SET OF TEST CASES…?
12. HOW MUCH EFFORT IS NEEDED ..?
ASK YOURSELF THIS QUESTIONS:
1. WHAT IS THE AMOUNT OF TIME THAT IT WILL TAKE TO CREATE THE REGRESSION TESTS..?
2. WHAT IS THE AMOUNT OF TIME THAT IT WILL TAKE TO EXECUTE THE REGRESSION TESTS..?
3. WHAT ARE THE COSTS OF THIS EFFORT (BASED ON THE ANSWERS THAT YOU PROVIDE ON
Q1/2)..?
13. MAINTENANCE
CREATING THE REGRESSION TEST PLAN, IS PROBABLY THE EASY PART, THE
HARD PART IS TO MAKE SURE THAT THIS TESTS WILL REMAIN UPDATED
PERVERSION, THEREFORE, YOU NEED TO MAKE SURE THAT YOU
UNDERSTAND THE IMPACT OF THE MAINTENANCE COSTS AND THE EFFORT
THAT IT WILL TAKE FROM YOUR TEAM.
14. TEST PRIORITIZATION
REGRESSION TESTS MAY INCLUDE THOUSANDS OF TEST CASES, IN SOME
SITUATIONS YOU SIMPLY DON’T HAVE THE TIME TO EXECUTE THEM ALL.
THEREFORE, YOU MUST PRIORITIZE THE TESTS TO RUN IN THE ORDER THAT
WILL GUARANTEE THAT YOU COVER THE MOST CRUCIAL TESTS FIRST.
15. CAN YOU AUTOMATE..?
CAN YOU AUTOMATE YOUR TESTS OR NOT..? THE ANSWER TO THIS
QUESTION WILL DETERMINE HOW MANY TESTS YOU CAN WRITE
AND RUN PER TESTING CYCLE.
