10 Years of Codemanship

2019 marks the 10th anniversary since I started my training an coaching company for developers, Codemanship.

Since 2009, I've trained more than 3,000 developers on public coourses and client-site workshops, and hundreds of thousands more have downloaded the free tutorials, watched the free screencasts and read the TDD course book online.

I've been lucky enough to work with some great clients, including the BBC, Sage, UBS, Elsevier, John Lewis, Samsung, ASOS, Ordnance Survey and many more great companies, and worked all over the UK, as well as in Ireland, France, Germany, Spain, Portugal, the Netherlands, Norway, Sweden, Finland, Romania and Poland.

I'm also proud to have started the original Software Craftsmanship conference that inspired many more, to have - with your help - raised tens of thousands of pounds for Bletchley Park, and for maths and coding clubs. I've produced a sell-out West End comedy show, and even collaborated on an album that made it into Amazon's dance top 20!

In this time of rapid change and uncertainty, who knows what the next 10 years of Codemanship may bring. One thing's for sure: it won't be dull!

To celebrate 10 years of Codemanship, I'm offering 10 exclusive 1-day code craft training workshops to be run on client sites.

You can choose from:

  • TDD
  • Software Design Principles
  • Refactoring
  • Unit Testing

And any one of 10 Tuesdays or Thursdays coming up between now and Brexit (if you're in the EU, get 'em while you can!!!)

Just pick your date, and choose your course, whip out the company credit card, and Bob's your uncle. (Payment by invoice is also available.)

Each 1-day workshop costs £1,795 for up to 20 people - that's as little as £90 per person. (Normal price for a 1-day code craft workshop is £3,995.)

Team Craft - New Codemanship Workshop for 2019

I'm delighted to announce the launch of a new Codemanship workshop for 2019. Team Craft is a one-day workshop for 6-12 people that's stretches your skills in collaborative design and continuous delivery.

It's the product of 10 years running team exercises as part of Codemanship training workshops, as well as at conferences and meet-ups around the world. These experiences have been consolidated and refined into an action-packed day that will turbo-charge the Team Fu of new and established teams alike.

It promotes technical team skills like:

  • Collaborative Design
  • Mob Programming
  • Trunk-based Development
  • Continuous Integration and Continuous Delivery

Team Craft is a completely hands-on workshop that reaches the parts other workshops don't.

Over the course of the day, participants will design and deliver a working solution to a realistic real-world problem as a team.

From a standing start, they will:

  • Break down the requirements
  • Assign work to individuals and/or pairs
  • Choose the technology stack
  • Set up version control
  • Set up a CI server to build and test the solution as it takes shape
  • Agree on a high-level design and establish the interfaces and contracts between components/services
  • Test-drive the implementation of the components
  • Demonstrate a working end product to their "customer" (the trainer)

The emphasis is on learning by doing, with a 45-minute introduction with key tips on how to succeed as a team, and ending with a 45-minute retrospective where we will draw out lessons learned in the 5-hour practical exercise.

TDD Training - Part I (Classic TDD), London, Sat Dec 1st

My flagship Codemanship TDD training course returns in a series of 3 standalone Saturday workshops aimed at self-funding learners.

It's the exact same highly popular training we've delivered to more than 2,000 developers since 2009, with 100% hands-on learning reinforced by our jam-packed 200-page TDD course book.

Part 1 is on Saturday Dec 1st in central London, and it's amazingly good value at just £99.

Part I goes in-depth on "classic" TDD, the super-important refactoring discipline, and software design principles that you can apply to your code as it grows and evolves to keep it easy to change so you can maintain the pace of development.

  • Why do TDD?

  • An introduction to TDD

  • Red, Green, Refactor

  • The Golden Rule

  • Working backwards from assertions

  • Testing your tests

  • One reason to fail

  • Writing self-explanatory tests

  • Speaking the customer's language

  • Triangulating designs

  • The Refactoring discipline

  • Software Design Principles
    • Simple Design

    • Tell, Don’t Ask

    • S.O.L.I.D.

The average price of a public 1-day dev training course, per person, is around £600-800. This is fine if your company is picking up the tab.

But we've learned over the years that many devs get no training paid for by their employer, so we appreciate that many of you are self-funding your professional development. Our Saturday workshops are priced to be accessible to professional developers.

In return, developers who've attended our weekend workshops have recommended us to employers and colleagues, and most of the full-price client-site training and coaching we do comes via these referrals.

Please be advised that we do not allow corporate bookings on our workshops for self-funders. Group bookings are limited to a maximum of 4 people. If you would like TDD training for your team(s), please contact me at jason.gorman@codemanship.com to discuss on-site training.

50% Off Codemanship Training for Start-ups and Charities

One of the most fun aspects of running a dev training company is watching start-ups I helped a few years ago go from strength to strength.

The best part is seeing how some customers are transforming their markets (I don't use the "d" word), and reaping the long-term benefits of being able to better sustain the pace of innovation through good code craft.

I want to do more to help new businesses, so I've decided that - as of today - start-ups less than 5 years old, with less than 50 employees, will be able to buy Codemanship code craft training half-price.

I'm also extending that offer to non-profits. Registered charities will also be able to buy Codemanship training for just 50% of the normal price.

Third-Generation Testing - Øredev 2018, Malmö, November 22nd

If you're planning on coming to Øredev in Sweden this November, I'm running a brand new training workshop on the final day about Third-Generation Software Testing.

First-generation testing was manual: running the program and clicking the buttons ourselves. We quickly learned that this was slow and often patchy, creating a severe bottleneck in development cycles.

Second-generation testing removed that bottleneck by writing code to test our code.

But what about the tests we didn't think of?

Exploratory testing brought us back to a manual process of exploring what else might be possible - what combinations of inputs, user actions and pathways - using the code we delivered, outside of the behaviours encoded in our automated tests.

Manual exploratory testing suffers from the same setbacks as any kind of manual testing, though. It's slow, and can miss heaps of cases in complex logic.

Third-generation testing automates the generation of the test cases themselves, enabling us to explore much wider state spaces than a manual process could ever hope to achieve. With a little extra test code, and a bit of ingenuity, you can explore thousands, tens of thousands, hundreds of thousands and even millions of extra test cases - combinations, paths, random inputs and ranges - using tools you already know.

In this workshop, we'll explore some simple techniques for adapting and reusing our existing unit tests to exhaustively test our critical code. We'll also look at techniques for identifying what code might need us to go further, and how we can use Cloud technology to execute millions of extra tests in minutes.

Adopting TDD - The Codemanship Roadmap

I've been doing Test-Driven Development for 20 years, and helping dev teams to do it for almost as long. Over that time I've seen thousands of developers and hundreds of teams try to adopt this crucial enabling practice. So I've built a pretty clear picture of what works and what doesn't when you're adopting TDD.

TDD has a steep learning curve. It fundamentally changes the way you approach code, putting the "what" before the "how" and making us work backwards from the question. The most experienced developers, with years of test-after, find it especially difficult to rewrite their internal code to make it comfortable. It's like learning to write with your other hand.

I've seen teams charge at the edifice of this learning curve, trying to test-drive everything from Day #1. That rarely works. Productivity nosedives, and TDD gets jettisoned at the next urgent deadline.

The way to climb this mountain is to ascend via a much shallower route, with a more gentle and realistic gradient. You will most probably not be test-driving all your code in the first week. Or the first month. typically, I find it takes 4-6 months for teams to get the hang of TDD, with regular practice.

So, I have a recommended Codemanship Route To TDD which has worked for many individuals and teams over the last decade.

Week #1: For teams, an orientaton in TDD is a really good idea. It kickstarts the process, and gets everyone talking about TDD in practical detail. My 3-day TDD workshop is designed specifically with this in mind. It shortcuts a lot of conversations, clears up a bunch of misconceptions, and puts a rocket under the team's ambitions to succeed with TDD.

Week #2-#6: Find a couple of hours a week, or 20 minutes a day, to do simple TDD "katas", and focus on the basic Red-Green-Refactor cycle, doing as many micro-iterations as you can to reinforce the habits

Week #7-#11: Progress onto TDD-ing real code for 1 day a week. This could be production code you're working on, or a side project. The goal for that day is to focus on doing it right. The other 4 days of the week, you can focus on getting stuff done. So, overall, your productivity maybe only dips a bit each week. As you gain confidence, widen this "doing it right" time.

Week #12-#16: By this time, you should find TDD more comfortable, and don't struggle to remember what you're supposed to do and when. Your mind is freed up to focus on solving the problem, and TDD is becoming your default way of working. You'll be no less productive TDD-ing than you were befpre (maybe even more productive), and the code you produce will be more reliable and easier to change.

The Team Dojo: Some teams are keen to put their new TDD skills to the test. An exercise I've seen work well for this is my Team Dojo. It's a sufficiently challenging problem, and really works on those individual skills as well as collaborative skills. Afterwards, you can have a retrospective on how the team did, examining their progress (customer tests passed), code quality and the disciplie that was applied to it. Even in the most experienced experienced teams, the doj will reveal gaps that need addressing.

Graduation: TDD is hard. Learning to test-drive code involves all sorts of dev skills, and teams that succeed tell me they feel a real sense of achievement. It can be good to celebrate that achievement. Whether it's a party, or a little ceremony or presentation, when organisations celebrate the achievement with their dev teams, it shows reall commitment to them and to their craft.

Of course, you don't have to do it my way. What's important is that you start slow and burn your pancakes away from the spotlight of real projects with real deadlines. Give yourself the space and the safety to get it wrong, and over time you'll get it less and less wrong.

If you want to talk about adopting TDD on your team, drop me a line.

The Entire Codemanship TDD Course Book - Absolutely Free

Changes are afoot with my code craft training and coaching company, Codemanship, and as part of that, I'm making my 222-page TDD course book available to download as a spiffy full-colour PDF for free.

It covers everything from the basics of Red-Green-Refactor, through software design principles to apply to your growing code, all the way up to advanced topics other TDD books and courses don't reach, like mutation testing, property-based and data-driven testing and Continuous Inspection. Many people who've read the book have commented on how straightforward and to-the-point it is. Shorter than most TDD/code craft books, but covers more, all in practical detail.

Of course, to get the best from the book, you should try the exercises.

Better still, try the exercises with the guy who wrote the book in the room to guide you.
