Testing and Automation
TDD: seriously, try it !
Have you heard of TDD? Are you interested or familiar with this practice but have never been able to understand it?
In this session I'd like to present the benefits of Test-Driven Development (TDD), explaing how it works and what the benefits are of using it. We will see in a more detailed approach this way of developing software, where our software is always built guided by tests.
We will go over some history about TDD, which is the main process we must follow when we work with this mechanic and the rules that surround it. We will also list the main advantages and disadvantages that most developers who practice TDD find and whether the arguments in favour add up to more than those that subtract. Finally, we will review some good habits and practices when applying TDD and see how to do it step by step with a Java code example.
At the end of the session, I hope attendees will have a wider understanding of what TDD is, what advantages it brings, why it is interesting to master it and also that you will take with you some tricks and good practices to be able to apply them in your day-to-day life when writing code 😉

KernelCI has now been a Linux Foundation project for just over a year. During that time, it has set the basis needed to fulfil its mission of being the de facto upstream kernel test system. We can now build many more kernels, run many more tests and collate results from many more test labs. We also have a growing team of core contributors, an on-going commitment from our member companies as well as more presence in the kernel community. Together, we are gathering the momentum needed to start a ...

Introduction to the Linux Test Project Fuzzy Sync C library, developed for reproducing data races in the Kernel from user land. Will cover a simple contrived data race, entirely in user land, to demonstrate the basics. Then we will move onto real world examples within the kernel, including when a delay bias is required to ensure a particular chronological order of events. Fuzzy Sync was developed for reproducing Linux kernel bugs, however it may be used to collide events in user land, another ...

Tracing is awesome. Full stop. But what tracing? In fact, even just on Linux, there are quite a few tracing solutions, aren't there they? In this session we'll show off and compare ftrace and LTTng and, for visualizing the collected data, KernelShark and Trace Compass when tracing both baremetal and virtualized systems.

Embedded development is complex enough. By automating repetitive parts during development and employing testing, a lot of time can be saved and human errors avoided. Additionally, embedded development is usually a team effort: scarce hardware must often be shared between developers and sometimes even with automated testing. labgrid is an open source tool for remote control and testing of Embedded Linux Devices in a distributed lab. In this talk the presenter takes a look at how labgrid can be ...

Commonly used CI systems operate as SAAS solutions, where the user is not running the CI stack locally. This lends itself to debugging pitfall as developers cannot easily reproduce the problem locally and cannot interactively examine it. This talk proposes an inverted design, where self-operated CI tool can be used both in the cloud as well as locally, supporting interactive debugging sessions.

It brings the concept of roles that help classify your automation tasks/playbooks and group them by purpose. But : When should we use Ansible roles? How to create and test Ansible roles? What tools do we have to ease the process? How can we apply best practices of software development (TDD) to ensure your roles are doing what they are intended to? This talk will introduce you to Ansible Roles testing will Ansible Molecule; a tool used to drive ansible roles testing. Moreover, we will try to ...
