Mutation testing is a process to verify the correctness of our tests. It adds a new metric, "mutation coverage", that complements the line coverage to improve our software.
Kill the mutants and test your tests - Roy van RijnNLJUG
Quis custodiet ipsos custodes? Better known as: *Who watches the watchmen?* We are all writing tests, doing TDD, BDD. We measure the quality of the tests with line coverage or (even better) branch coverage. This gives you a false sense of security. I've seen projects with tests which have 100% branch coverage but not a single assertion! This is where mutation testing helps out. By creating broken mutated instances of your codebase (mutants) this should result in failing unit tests. This way we can verify that slight code changes (like real life bugs) actually break your tests. In this talk I'll explain what mutation testing is and how it works. We'll also compare some Java frameworks (PIT, Jester, Jumble) that enable automatic mutation testing in your continuous build and how you can start doing mutation testing *right now*.

What are the prerequisites of a successful retrospective? What impediments should be analysed during this meeting? Does the goal of the retrospective influence its format? What are some retrospective formats and what kind of activities do they require for each step? These are some of the questions I will answer during this talk.
Expect a lot of examples which will generate insights on how to create custom retrospectives fit for your team.
Create Software Design with unit testing, build user experience with UX testing, check definition of done with functional testing – all these are my day-to-day activities. Indeed, I am a developer who has found the value of testing to deliver quality software.
In this presentation I share with you how I have come to use tests for: understanding the features, choosing the best user experience design, choosing the best technical solution, implementing the features and test them to create a reliable system.
You will see practical examples of how tools like Jasmine, Spock, Geb are used for the above types of tests. You will see a project with test code and we will discuss how testing can effectively enhance your professional performance.

A tale of scale & speed: How the US Navy is enabling software delivery from l...sonjaschweigert1
Rapid and secure feature delivery is a goal across every application team and every branch of the DoD. The Navy’s DevSecOps platform, Party Barge, has achieved:
- Reduction in onboarding time from 5 weeks to 1 day
- Improved developer experience and productivity through actionable findings and reduction of false positives
- Maintenance of superior security standards and inherent policy enforcement with Authorization to Operate (ATO)
Development teams can ship efficiently and ensure applications are cyber ready for Navy Authorizing Officials (AOs). In this webinar, Sigma Defense and Anchore will give attendees a look behind the scenes and demo secure pipeline automation and security artifacts that speed up application ATO and time to production.
We will cover:
- How to remove silos in DevSecOps
- How to build efficient development pipeline roles and component templates
- How to deliver security artifacts that matter for ATO’s (SBOMs, vulnerability reports, and policy evidence)
- How to streamline operations with automated policy checks on container images

Why You Should Replace Windows 11 with Nitrux Linux 3.5.0 for enhanced perfor...SOFTTECHHUB
The choice of an operating system plays a pivotal role in shaping our computing experience. For decades, Microsoft's Windows has dominated the market, offering a familiar and widely adopted platform for personal and professional use. However, as technological advancements continue to push the boundaries of innovation, alternative operating systems have emerged, challenging the status quo and offering users a fresh perspective on computing.
One such alternative that has garnered significant attention and acclaim is Nitrux Linux 3.5.0, a sleek, powerful, and user-friendly Linux distribution that promises to redefine the way we interact with our devices. With its focus on performance, security, and customization, Nitrux Linux presents a compelling case for those seeking to break free from the constraints of proprietary software and embrace the freedom and flexibility of open-source computing.

Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).

Climate Impact of Software Testing at Nordic Testing DaysKari Kakkonen
My slides at Nordic Testing Days 6.6.2024
Climate impact / sustainability of software testing discussed on the talk. ICT and testing must carry their part of global responsibility to help with the climat warming. We can minimize the carbon footprint but we can also have a carbon handprint, a positive impact on the climate. Quality characteristics can be added with sustainability, and then measured continuously. Test environments can be used less, and in smaller scale and on demand. Test techniques can be used in optimizing or minimizing number of tests. Test automation can be used to speed up testing.
