Fast-running automated unit tests are the foundation on which great code is built, and an absolute must for any team that needs to sustain the pace of delivery, both with and without AI coding assistants.

This action-packed 1-day workshop introduces developers to fundamental unit testing concepts and practices, using the most popular frameworks for C#, Java, JavaScript, Python and PHP developers.

With an emphasis on the practical, this workshop is packed full of hands-on demonstrations (20%) and exercises (80%). Participants learn together with pair and mob programming.

FAQ

Who should attend?

This training workshop is aimed at JavaScript, Python, C#, PHP and Java developers with at least one year's experience programming in their chosen language. It's often attended by technical leaders who wish to keep their code craft skills up-to-date, too.

What should I bring?

You will need a suitable computer with your favourite JS, PHP, Python, C# or Java editor/IDE installed. On-site courses will require a room large enough to comfortably accomodate all participants, good, reliable Internet access (Wi-Fi), and a data projector or suitably large TV (with HDMI input) that will allow participants to read code from the back of the room. You will find a pen and paper handy.

Where is this training available?

Online training is available whereever you are, pretty much. (There are a few countries it's sadly not possible to do business with, of course.) Onsite training is available across the UK, Europe and many other regions. Ask us.

Who will be our trainer?

9/10 times, the trainer will be Codemanship founder and course author Jason Gorman. Jason has 38 years' programming experience and three decades of professional experience as a developer, technical lead and software architect. He's run hundreds of code craft training workshops over the last 20 years, and is a very experienced teacher and mentor. If, for any reason, Jason isn't available for your workshop, we'll inform you well in advance and offer you a trainer of similar industry seniority.

Will I need to write code in this workshop?

Yes. You will most definitely be writing code in this workshop. Business analysts, testers, project managers etc may find it useful to sit in and observe -at no charge - if they want to gain an understanding of Test-Driven Development and how it fits into the overall software development cycle, but this is 100% a hands-on workshop.

Is it available for other languages?

Since 2009, we've delivered training for developers working in C++, Swift, Go, Kotlin, Groovy, Ruby and many other languages. Ask us about customised courses.
