'Model Based Test Design' by Mattias ArmholtTEST Huddle
MBT (Model Based Testing) has been used within my department in Ericsson since 2007. As an MBT tool we have been using Conformiq Modeler, which is a commercially available tool. This has been a great success, and is now our main way of working when verifying functional requirements.
Until now, MBT has neither within Ericsson nor outside, only been used very rarely for verification of non-functional requirements, such as performance testing, load testing, stability and robustness tests and characteristics measurements.
This presentation covers the work of two Master Students, who in 2010 performed a study of the possibilities to use MBT for verifying non-functional requirements. One of the results of this study was a new method, inspired by MPDE (Model Driven Performance Engineering), where non-functional requirements can be covered by test models describing the functional behavior. Test Cases can then be generated from these models with an MBT tool.
The proposed method provides different possibilities to handle the non-functional requirements. The requirements can, for example, be introduced with new dedicated states in the behavioral model, or be introduced by extending the existing state model. Another possibility is to implement the non-functional requirements in the test harness, and by that keeping the model simple. The most realistic scenario, however, is a combination of all the above. The grouping and allocation of both functional and non-functional requirements should be considered already in the early test analysis phase.
The new method has been tried out and evaluated. It has been proved useful and fully applicable, and there are clear indications that it is beneficial, and that project lead time can be reduced by using it. We have therefore now started to apply this method in our new development projects.
The presentation includes examples of real cases where MBT has been used for verifying non-functional requirements.

'Automated Reliability Testing via Hardware Interfaces' by Bryan BakkerTEST Huddle
The case study described in this presentation has taken place at a medical equipment manufacturer. The product developed was a medical x-ray device used during surgery operations. The system generates x-rays (called exposure) and a detector creates images of the patient based on the detected x-ray beams (called image acquisition). The image pipeline is real-time with several images per second, so the surgeon can e.g. see exactly where he is cutting the patient.
The presentation describes the approach that has been taken to develop an automatic testing framework in order to execute reliability test cases and identify reliability issues. To achieve the control of the system under test, the existing hardware interfaces (physical buttons of the different keyboards, handswitches and footswitches) were used to inject the system with actions (with the use of LabVIEW). This has been done to minimize the so-called probe effect.
The expected results of the test cases have been automatically retrieved from the log files generated by the system. This way the test framework could react on system failures immediately, without wasting valuable test time on scarce test systems. The log files were used to extract information about the performed actions and failures in order to measure the MTBF (Mean Time Between Failures) of different critical system functions (like start-up of the system, and image acquisition). The Crow-AMSAA model for reliability measurements has been chosen to report reliability metrics to the organization. A Return-On-Investment calculation has been performed to get buy-in from senior management who provided additional funding to further develop the testing framework, and to apply the same ideas to different products and projects.
The presentation explains the points which were crucial for the success of this approach to automated reliability testing and briefly explains future plans and extensions (e.g. operational profiles).

Testing Applications—For the Cloud and in the CloudTechWell
As organizations adopt a DevOps approach to software development, they work to shorten test cycles, begin testing earlier, and test continuously. However, one challenge still remains―the unavailability of complete and realistic production-like test environments. Technologies like service virtualization help, but there comes a time when you need additional computing resources to deploy and test the application. Today's cloud technology allows teams to spin up test labs on demand. Join Al Wagner as he describes the various clouds―public, private, and hybrid―and the cloud services available today. By combining the cloud with service virtualization, teams can now test applications end-to-end much earlier in the delivery lifecycle. Learn how teams can use today’s SaaS offerings, deployed on cloud technology, to manage their test effort and drive test execution. Explore how you can use clouds throughout the delivery lifecycle as your organization works to migrate and virtualize legacy applications. Take testing to a new level and test with greater efficiency―in the cloud.

Adding Value in the Cloud with Performance TestRodolfo Kohn
System quality attributes such performance, scalability, and availability are among the main concerns for cloud application developers and product managers. There are many examples of notable system failures that show how a company business can be affected during key events like a Cyber Monday. However, many difficulties come up when a team intends to consciously manage these type of quality attributes during development and operations. It is possible to group these difficulties in two main aspects: human aspects and technical aspects. During this presentation, I will share main technical difficulties we had to deal with in the last seven years working with different cloud services as well as key technical performance, scalability, and availability issues we were able to find and solve. It is about cases that are relevant through different products, technologies, and teams.
A Year of “Testing” the Cloud for Development and TestTechWell
Jim Trentadue describes the first year his organization used the cloud for its non-production needs: development, testing, training, and production support. Jim begins by describing the components of a cloud environment and how it differs from a traditional physical server structure. To prove the cloud concept, he used a risk-based model for determining which servers would be migrated. The result was a win for the organization from a time-to-market and cost savings perspective. Jim shares his do’s and don’ts for moving to the cloud. Do’s include ensure you identify all costs associated with the new cloud infrastructure, implement a risk-based approach to cloud migration, define a governance model, and define Service Level Agreements for your cloud vendor. Jim warns against creating an open-ended environment without a charge-back model to allocate costs and failing to continuously monitor the overall environment. Take back practical and proven recommendations and practices to make your move to the cloud a breeze.

Lessons from Large-Scale Cloud Software at DatabricksMatei Zaharia
Keynote by Matei Zaharia at SOCC 2019
Abstract:
The cloud has become one of the most attractive ways for enterprises to purchase software, but it requires building products in a very different way from traditional software, which has not been heavily studied in research. I will explain some of these challenges based on my experience at Databricks, a startup that provides a data analytics platform as a service on AWS and Azure. Databricks manages millions of VMs per day to run data engineering and machine learning workloads using Apache Spark, TensorFlow, Python and other software for thousands of customers. Two main challenges arise in this context: (1) building a reliable, scalable control plane that can manage thousands of customers at once and (2) adapting the data processing software itself (e.g. Apache Spark) for an elastic cloud environment (for instance, autoscaling instead of assuming static clusters). These challenges are especially significant for data analytics workloads whose users constantly push boundaries in terms of scale (e.g. number of VMs used, data size, metadata size, number of concurrent users, etc). I’ll describe some of the common challenges that our new services face and some of the main ways that Databricks has extended and modified open source analytics software for the cloud environment (e.g., designing an autoscaling engine for Apache Spark and creating a transactional storage layer on top of S3 in the Delta Lake open source project).
Bio:
Matei Zaharia is an Assistant Professor of Computer Science at Stanford University and Chief Technologist at Databricks. He started the Apache Spark project during his PhD at UC Berkeley in 2009, and has worked broadly on datacenter systems, co-starting the Apache Mesos project and contributing as a committer on Apache Hadoop. Today, Matei tech-leads the MLflow open source machine learning platform at Databricks and is a PI in the DAWN Lab focusing on systems for ML at Stanford. Matei’s research was recognized through the 2014 ACM Doctoral Dissertation Award for the best PhD dissertation in computer science, an NSF CAREER Award, and the US Presidential Early Career Award for Scientists and Engineers (PECASE).
Semantic Validation: Enforcing Kafka Data Quality Through Schema-Driven Verif...HostedbyConfluent
"Incorrect data produced into Kafka can be a poison pill that has the potential to disrupt businesses built upon Kafka. The “Semantic Validation” feature is designed to address the challenges posed by incorrect or unexpected data in Kafka’s data processing pipelines, with the goal of mitigating such disruptions. By allowing users to define robust field constraints directly within schemas, such as Avro, we aim to enhance data quality and minimize the downstream impacts of inaccurate data in Kafka.
Furthermore, this feature can be expanded to include offline data processing, in addition to Kafka and Flink real-time processing. By combining real-time processing, batch analytics, and AI data pipelines, a global semantic validation system can be built.
In our upcoming talk, we will delve into the use cases of this feature, discuss its architecture, provide examples of defining rules, and explain how we enforce these rules. Ultimately, we will demonstrate how this feature can significantly enhance reliability and trustworthiness in Uber’s data processing pipelines."

Keys to continuous testing for faster delivery euro star webinar TEST Huddle
Your business needs to deliver faster. To accommodate, Development needs to introduce fewer changes but in a much more frequent cadence. This creates a challenge for test teams to keep up with the rapid pace of change without compromising on quality. Automation is paramount to the success or failure of Continuous Delivery, and Continuous Testing enables early and frequent quality feedback throughout the CI/CD pipeline.
In this webinar, Eran & Ayal will explore how to implement Continuous Testing to ensure high quality releases in a Continuous Delivery environment; including what to test and when to automate new functionality in order to optimize your efforts.
In this webinar Carsten will explore the role of the tester in a Scrum team. He will examine where the tester play an important role in Scrum and how you can contribute to a teams performance.
Leveraging Visual Testing with Your Functional TestsTEST Huddle
Designing and implementing (or selecting) the right automation strategy, for functional testing, with visual testing, can help your project with greater test coverage while improving test scalability
This talk suggests how we might make sense of the tools landscape of the near future, where the pressure to modernise processes and automate is greatest, and what a new test process supported by tools might look like.
Takeaways:
- We need to take machine learning in testing seriously, but it won’t be taking our jobs just yet
- We don’t need more test automation tools; today we need tools that capture tester knowledge
- Tools that that learn and think can’t work for testers until we solve the knowledge capture challenge.

Growing a Company Test Community: Roles and Paths for TestersTEST Huddle
Over the past three years, our company’s test team has grown from three lonesome testers to a community of nine – with more planned. Since we don’t see testers as “click monkeys”, but as valuable and integrated project members who bring a specific skill set to the table, it’s important for us to choose testers well and to train them in various areas so that they can contribute, grow and see their own career path within testing.
To structure to our internal tester training program, we have been developing role descriptions, education paths and career options for our testers, which I’d like to share with you in this webinar.

It’s the same argument again and again. One side says “team members should all be able to do everything, and the programmers should do their testing and all testers should be writing code”. The other side says “No, that can’t possibly work – programmers don’t know how to test, they don’t have the right mindset”. And on and on it goes.

Large Language Models and the End of ProgrammingMatt Welsh
Talk by Matt Welsh at Craft Conference 2024 on the impact that Large Language Models will have on the future of software development. In this talk, I discuss the ways in which LLMs will impact the software industry, from replacing human software developers with AI, to replacing conventional software with models that perform reasoning, computation, and problem-solving.
In the testing literature, the term "load testing" is usually defined as the process of exercising the system under test by feeding it the largest tasks it can operate with. Load testing is sometimes called volume testing, or longevity/endurance testing.
Stress testing tries to break the system under test by overwhelming its resources or by taking resources away from it (in which case it is sometimes called negative testing). The main purpose behind this madness is to make sure that the system fails and recovers gracefully -- this quality is known as recoverability.

is about the limit for having the user feel that the system is reacting instantaneously, meaning that no special feedback is necessary except to display the result.
1.0 second
is about the limit for the user's flow of thought to stay uninterrupted, even though the user will notice the delay. Normally, no special feedback is necessary during delays of more than 0.1 but less than 1.0 second, but the user does lose the feeling of operating directly on the data.
10 seconds
is about the limit for keeping the user's attention focused on the dialogue. For longer delays, users will want to perform other tasks while waiting for the computer to finish, so they should be given feedback indicating when the computer expects to be done. Feedback during the delay is especially important if the response time is likely to be highly variable, since users will then not know what to expect.
