Episode 127 – Storming DD’s with Paul Rayner

Craig chats with Paul Rayner, a BDD and DDD expert who helps people bridge the gap of collaborative design between developers and business representatives, at YOW! West in Perth, and two old friends talk about the following:

* Agile Alliance Functional Testing Tool workshop (2011 in Salt Lake City)
* “Domain Driven Design” (Eric Evans) and “Working Effectively with Legacy Code” (Michael Feathers)
* The heart of DDD is about developing a rich model to allow you to deal with complex business domains
* Domain Driven Design Europe conference
* Design done well should pay off immediately, as well as in the medium to long term as well
* There are lot of overlaps between DDD and BDD, particularly the use of an ubiquitous language, BDD is a test first way to drive out your domain model
* YOW! West Keynote “EventStorming”
* Given When Then has a close relationship to modelling your domain events – a good model is one you can make assertions against
* “User Story Mapping” (Jeff Patton) is an example of how the community has started to build useful collaborative tools
* Example Mapping (Matt Wynne) visualises the perspectives of the Three Amigos and puts the focus on our understandings and our ignorances and provides a technique for the conversation
* Deliberate Discovery (Dan North and Liz Keogh) – where is our ignorance
* “Introducing EventStorming” (Alberto Brandolini) is a way of mapping out the domain or the business process using coloured sticky notes – what are the important events to support the behaviour required in our system
* You get a lot better result when you start at the end and work backwards to find insights
* Can use EventStorming to support lean processes such as value stream mapping (Craig’s lightbulb moment)
* “Coaching Agile Teams” (Lyssa Adkins) and how to make yourself a better coach
* Resistance as a Resource (Dale Emery) – helps to have a champion that you can support
* DDD continues to grow and evolve – the popularity of EventSourcing and CQRS have helped this

Episode 125: 10 Minutes with Dan North

dannorthAfter many failed attempts to get him on the podcast, Craig finally catches up with Dan North at YOW! Conference on his way out the door to the airport and in a quick chat they cover:

  • BDD – developing an application by looking at its behaviour from the perspective of its stakeholders (people who’s live you touch)
  • Given When Then – “given” is setting up the world in a well known way, “when” is me interacting with the application as a stakeholder and “then” is what I expect to happen
  • BDD is not the same as writing automated tests, they are orthogonal – “Test-Driven Development Is Not About Testing
  • Software, Faster – collection of patterns for people who have been around Agile and are asking “now what” – “Software, Faster” book in progress
  • YOW! 2015 talk “Delivery Mapping: Turning the Lights On

Episode 117: The Changing Role of a Tester with Mark Pedersen

mpCraig is at the YOW! Connected conference and talks to Mark Pedersen, the CTO at KJR, and they talk all things quality and testing:

  • the changing role of a tester in an Agile environment, it clarifies the role rather than making it blurrier
  • in an Agile environment it does not make sense to have a Test Manager role anymore
  • the number of dedicated testing roles are decreasing, but becoming more important and valuable
  • most organisations say that they use both waterfall and agile frequently
  • build your skills in either a quasi analysis / product owner / acceptance criteria role or get up to speed with sensible technical automation tools for your tech stack
  • TDD – good idea but not many organsations practicing it in a dedicated way, unit testing in most industries is a luxury
  • BDD – does not make TDD obsolete, defining acceptance criteria upfront helps understand what we need to code
  • pair programming – does not deliver much benefit from a test perspective, unless the tester has technical expertise, adoption is still very low
  • YOW! Connected talk “Building Mobile App Test Automation
  • mobile testing is challenging and IoT will take it to another level – customer expectations are higher for these devices, they are thought of more like traditional mechanical devices
  • mobile and IoT is driving the demand for testers to become more technical – more API and distributed technology tests

Episode 83: Making Impacts with Gojko Adzic

GojkoAdzicGojko Adzic “does computers” which means he helps people deliver software and he caught up with Craig on a recent YOW! DepthFirst tour of Australia. Gojko is the author of numerous books including “Bridging The Communication Gap“, “Specification by Example“, “Impact Mapping” and “50 Quick Ideas to Improve Your User Stories“.

  • XP – started with “Extreme Programming Explained” which was really about developers ruling the world – XP is not dead, it won!
  • TDD has crossed the chasm to mainstream
  • Sturgeons Law – 90% of anything is going to be crap
  • Continuous integration and automation has opened up a world of possibilities
  • “Bridging the Communication Gap” – about finding ways to break dysfunctional processes in organisations
  • Agile Testing” by Lisa Crispin and Janet Gregory
  • The most valuable companies in the world are software companies
  • It’s more about the right people being involved rather than narrowly defined roles
  • “Specification by Example” – a collaborative way of coming up with good requirements and tests involving a cross functional team
  • Pschologically people perceive that tests come after development – in that case you have already failed
  • BDD – no canonical definition, would love BDD and SBE to be the same thing
  • “Impact Mapping” – based on a Swedish interaction design process – about setting goals and strageies
  • Impact Mapping uptake outside of IT – Marcus Hammarberg on Doctors in Indonesia and Ahmad Fahmy on helping orphanges in Egypt
  • “50 Quick Ideas To Improve Your User Stories” – a lot more to good user stories than just a template
  • Hamburger Slicing – last resort technique for technical story breakdown to think about options for value
  • Product Management is the big missing piece – teams could benefit from doing this better
  • As an industry we produce too much software – need to change the percentage of software that can achieve something big
