Test Driven Development

De 35ᵉ monthly meetup van [Nimma.codes](https://www.nimma.codes/). Elke laatste dinsdag van de maand. Een cross-language user group voor software developers in de regio Arnhem-Nijmegen. Let op: het eten is er om 17:30. We starten om 18:00 met de opening. *We houden er niet van om eten te verspillen. Ben je verhinderd? Geen probleem, maar meld je uiterlijk een dag voor de meetup af.* **Programma** * 17:30 - 18:00 Inloop + food/drinks * 18:00 - 18:45 **Webbeveiligingsstandaarden: Wat, Waarom en Hoe? - Arjan Eising** * 18:45 - 19:00 Pauze * 19:00 - 19:30 **Django And Its Ecosystem - Quint Wessels** * 1930 - 20:00 **Professional Django Development - Kees Hink** * 20:05 - 21:00 Netwerken en gezelligheid In deze editie hebben we één wat langer praatje en twee korte. In de eerste talk van **Arjan** gaat hij ons wat vertellen over webbeveiligingsstandaarden. Moderne browsers gebruiken een scala aan technieken om websites en gebruikers te beschermen tegen kwaadaardige aanvallen. Deze standaarden zijn cruciaal om de integriteit van gegevens te waarborgen en het vertrouwen van gebruikers te behouden. Ze voorkomen dat gevoelige gebruikersgegevens op ongewenste plaatsen belanden of dat ongewenste code wordt uitgevoerd. Voorbeelden zijn Cross-Origin Resource Sharing (CORS) en Content Security Policy (CSP) voor het veilig aanroepen van externe content en API's. Deze presentatie behandelt de belangrijkste webbeveiligingsstandaarden en de bescherming die ze bieden. Daarnaast krijg je praktische tips voor het opzetten van veilige API's en het effectief aanroepen daarvan vanuit de front-end. **Quint** gaat ons een kijkje geven op Python, waar het staat, en zijn (open-source) ecosysteem. **Kees** gaat ons meenemen in hoe Four Digits Django en WagtailCMS projecten ontwikkelt, implementeert en onderhoudt zonder gek te worden.

#### Level: Everyone welcome Musical theatre is improvisational theatre where music and sound take the lead. This does not mean you have to sing or perform improvised songs, although that can happen. Instead, musicality in its broadest sense becomes the starting point for scenes. Sound, rhythm, tempo, and tone guide what unfolds on stage. In this course, music is not decoration or background. It becomes an active scene partner. A rhythm can create a character, a sound can set a mood, and a musical impulse can shape the entire direction of a scene. The module is inspired by the work of companies and makers such as Orkater, Monty Python, Het Amsterdams Bostheater, and the Ashton Brothers, where musicality, playfulness, and theatrical imagination meet. #### What will we do Throughout the course, you will explore how sound and music can drive improvisation in different ways. Sometimes a scene will emerge purely from a sound, rhythm, or musical texture. At other times, music will support and deepen an existing scene, strengthening emotion, atmosphere, and timing. You will experiment with how musical choices influence pace, tension, and emotional impact. By treating sound as a creative force rather than an extra layer, you will learn how music can provide structure and momentum, even in scenes without words. #### Who is this course for This course is open to everyone. You do not need to be a musician, play an instrument, or feel confident about singing. Curiosity and a willingness to experiment are far more important than musical skill. The course is built on the belief that everyone has enough musicality to create meaningful and powerful improvised scenes. To make sure the group feels safe and comfortable, there may be a short intake beforehand. This is not about judging musical ability, but about checking whether you feel excited to explore sound, voice, and music in a playful way. #### What will we work on During the course, we will focus on four core elements. 1. Voice use * Exploring the musical possibilities of the voice, from raw sounds and textures to rhythm and melody. 2. Making music * Creating music with simple tools and everyday objects, learning how even the most unexpected sounds can strengthen a scene. 3. Scenes born from music * Discovering how music itself can generate characters, relationships, and structure without starting from text or narrative. 4. Music supporting scenes * Using music to enhance emotion, atmosphere, tension, and transitions within scenes. #### Why take this module This course invites you to experience improvisation from a completely different angle. By starting from sound and feeling instead of words and ideas, you open up new creative pathways and deepen your connection to instinct, timing, and emotion. Many participants find this approach both liberating and surprisingly moving. #### Review “My other improv group, with 20 to 30 years of experience, were moved to tears by what Iwan achieved in his lessons. Two members who had always been told they could not sing and should not use their voice were suddenly singing freely and effortlessly. Iwan opens up new possibilities of how to use music and voice.” *Marieke van Laar* #### About the teacher Iwan Dam is a highly sought after improvisation actor with extensive experience on stage and screen. He has been teaching improv for many years and is known for his open, playful teaching style, combined with a strong focus on technique and personal growth. Iwan studied at the Academy of Performing Arts in Amsterdam, the Central School of Speech and Drama in London, and trained with well known Dutch theatre makers.

#### Level: Everyone welcome \*\*Voice Training for Improvisers\*\* Discover the power and possibilities of your voice. In this masterclass, we dive into the fundamentals of healthy and expressive voice use — essential for every improviser. You’ll learn how your voice works, how to use it effectively in scenes, and how to gain more freedom and control in both spoken text and singing. We will explore: \* how to warm up your voice effectively \* how to sing in tune (and why you sometimes think you’re singing off-key) \* how to play with volume, tone color, and dynamics \* how to use your voice to carry, color, or surprise within a scene This training is practical, playful, and immediately applicable on the improv floor. You’ll go home with concrete tools, greater confidence, and a voice ready for any improvisation challenge.

**ArnhemJUG** We are excited to announce the first meetup of 2026. We are welcomed by OpenValue Arnhem for the January meetup! **Agenda** * 17:00 CET walk-in * 17:30 – 18:30 Food and drinks * 18:30 – 19:30 talk: **Bigger Unit Tests are Better - why small unit test classes will slow you down** by **Peter Schuler** * 19:30 – 19:45 break * 19:45 – 20:45 talk: **Creating effective and objective architectural decision records** by **Piet van Dongen** * 20:45 – 21:30 drinks **Bigger Unit Tests are Better - why small unit test classes will slow you down** Do you take care that every class in your system has a separate unit test class? Are you a proud Test-First advocate? A code coverage evangelist? Are you the Sonar police in your team? Do you take pride in knowing all the quirks of your mocking framework? Then this session might be a cold shower for you. You will see how the general approach to unit testing might harm your flexibility. But a few simple changes in your approach will make your life better, your coding faster, your refactoring easier and your understanding of the business requirements stronger. In this presentation, you will learn new strategies that will help you make your unit tests bigger. First, guided by clear code examples, we will look at why having many small test classes may harm you. Secondly, you will understand why making the tests bigger is such an important improvement. And lastly, you will learn techniques and tricks that will help make your unit tests bigger. **About Peter Schuler** Peter is a lifelong Java developer with a passion for TDD and code quality. Lately he has become a Java community lead for the Rabobank as a side hustle. In his off time, he likes to work in the garden or goes for a short run. **Creating effective and objective architectural decision records** Documenting decisions is like eating your veggies as a kid: they keep telling you it’s good for you, but you just hate doing it. Architectural Decision Records (ADRs) to the rescue! ADRs are perfect for just-in-time, just-enough documentation for engineering teams and organizations. During this session, you will learn how to make architectural decisions effectively and objectively by: * Learning the structure of a good ADR (no more walls of text that nobody reads anyway!) * Practicing how to turn subjective choices into objective ones (no more pros and cons lists and tribal conflicts!) * Creating editable diagrams, fast (no more spending hours wrestling tools that your collaborators don’t know how to use!) * Collaborating quickly with technical and non-technical stakeholders (no more hours of Tower of Babel meetings!) * Reporting the decision using effective language and fit-for-audience diagrams (no more writing reports that end up unread in drawers!) Do you want to learn how to facilitate good decision making without spending weeks looking for consent? Then join this session and you will walk away a better software architecture decision facilitator. **About Piet van Dongen** Piet van Dongen is a senior software architect and engineering consultant at OpenValue, helping organizations solve complex technology challenges through effective software practices.

*(🇬🇧 English below)* Voordat een bordspel of kaartspel kan worden uitgegeven, moet er veel aan het spel getest worden om zeker te zijn dat het leuk is, duidelijk is en altijd goed werkt. Daarom komen we **elke 2 weken** met spelauteurs uit de regio samen om prototypes van spellen te testen en ze zo beter te maken en misschien ooit wel gepubliceerd te krijgen. Om 8 uur verzamelen we bij [StartUp Nijmegen](https://startupnijmegen.nl/) voor een speltestavond. Afhankelijk van het aantal aanwezigen en prototypes dat er wordt meegenomen (neem zelf ook iets mee als je wilt) vormen we een aantal groepen. Bij kleinere spellen kun je in de loop van de avond van groep wisselen, bij grotere spellen moet je dat even overleggen. **Ook als je zelf** **geen spellen maakt** of een spel hebt dat je wilt testen, ben je natuurlijk van harte welkom. Het is voor ontwerpers heel fijn om de mening van zo veel mogelijk andere mensen te krijgen. En heel eerlijk: het testen van nieuwe spellen is ook gewoon heel leuk! We gaan door tot een uur of 11, maar voel je vrij al eerder naar huis te gaan. Er is **gratis koffie** **en thee** bij StartUp Nijmegen. Voor fris, bier of wijn wordt een kleine bijdrage gevraagd. StartUp Nijmegen ligt tegenover het station. De auto kun je parkeren in de naastgelegen Keizer Karelparkeergarage (50 cent per uur). Er is hier ook een afgesloten fietsenstalling. De testavonden in Nijmegen zijn elke **2e dinsdag** en elke **4e woensdag** van de maand. Zet die dus vast in je agenda (tip: zet met [deze iCal link](https://calendar.google.com/calendar/ical/c_d2267afce516f9296468270649b3f44da6c06cbc0bc3de05f049992373db5f4f%40group.calendar.google.com/public/basic.ics) ze automatisch in je agenda)! Spellenmaakgilde Nijmegen maakt onderdeel van het [Nederlandse Spellenmaakgilde](https://spellenmaakgilde.nl/) en is onderdeel van het SAZ. Je vindt ons daarnaast ook in het #Nijmegen kanaal op de [Discord-server van het Spellenmaakgilde](https://discord.gg/6JzD6Sz2m5). 🇬🇧 **For English-speaking guests:** Before a board game or card game can be published, it must undergo extensive testing to ensure that it is enjoyable, clear, and always functions properly. Therefore, **every 2 weeks**, we gather with game authors from the region to test prototypes of games, thereby improving them and, perhaps, getting them published someday. At 8 PM, we gather at [StartUp Nijmegen](https://startupnijmegen.nl/) for a game testing evening. Depending on the number of attendees and prototypes brought (feel free to bring something yourself), we form several groups. For smaller games, you can switch groups throughout the evening, but for larger games, you should discuss this. **Even if you** **do not design games** or have a game you want to test, you are, of course, very welcome. It is very beneficial for designers to receive feedback from as many people as possible. And to be honest: testing new games is just a lot of fun! We continue until about 11 PM, but feel free to go home earlier if you wish. There is **free coffee** **and tea** at StartUp Nijmegen. A small contribution is requested for soft drinks, beer, or wine. StartUp Nijmegen is located opposite the station. You can park your car in the adjacent Keizer Karel parking garage (50 cents per hour). There is also a secure bicycle parking facility here. The testing evenings in Nijmegen are every **2nd Tuesday** and **4th Wednesday** of the month. So be sure to mark those in your calendar (tip: automatically add them to your calendar with [this iCal link](https://calendar.google.com/calendar/ical/c_d2267afce516f9296468270649b3f44da6c06cbc0bc3de05f049992373db5f4f@group.calendar.google.com/public/basic.ics))! The Spellenmaakgilde Nijmegen is part of the [Dutch Game Designers Guild](https://spellenmaakgilde.nl/) and is also a part of SAZ. You can also find us in the #Nijmegen channel on the [Discord server of the Game Designers Guild](https://discord.gg/6JzD6Sz2m5). And don't worry if you don't speak Dutch! We regularly have non-Dutch speaking guests, and everyone is welcome to join and have fun with us.

We’re heading into the south eastern Veluwe for a stunning scenic route that stays wonderfully quiet and almost deserted for a big part of the way, before building up to a truly spectacular grand finale! After around 6 km we reach the mysterious “Altar of the Loenermark” (Altaar van de Loenermark). I have no idea what it is, so we’ll discover it together. From there we continue through the beautiful heather and forest landscapes of Loenermark, one of those places where the Veluwe feels wide, wild, and open. Next we pass one of the quirkiest monuments in the Netherlands: the Ijkbasis Loenermark 1957–2007, a tribute to the calibration of measurement instruments from the past. The calibration itself might not sound exciting, but the location absolutely is, right in the middle of wide open heather, with big skies and that endless Veluwe feeling. It also marks about 11 km into the hike, a perfect spot to take our lunch break. After lunch we walk straight through the iconic National Park Veluwezoom, famous for its rolling grasslands and its fluffy semi wild cows. To finish in style, we end at Paviljoen De Posbank for a well earned snack or drink with a view over what many call the most spectacular heather of the Netherlands, complete with rolling hills. From there we head down towards Rheden, where you can easily catch the train or bus home. This is not a loop hike! **📍When and where to meet?** We’ll meet at 10h at busstop Loenen, Leeuwenbergweg. https://maps.app.goo.gl/LC3nNJQo57B5NnSy8 We are leaving a bit earlier otherwise we will find Paviljoen Posbank closed, which would be very sad. ⏰ We **start walking a few minutes after meeting up** — we don’t wait for latecomers, as the forest calls and daylight is short this time of year. **🚗 Coming by car?** This is not a loop hike. If you park in Loenen, you’ll need to make your own way back from Rheden afterwards. **⏸️ Planned Breaks** After **11 km**: Lunch break at **Ijkbasis Loenermark** (bring your packed lunch, this spot is truly in the middle of nowhere) **20 min** [https://maps.app.goo.gl/S5vAEpadAJs93ZrC7](https://maps.app.goo.gl/S5vAEpadAJs93ZrC7) After **19 km**: Snack or drink at **Paviljoen De Posbank** [https://maps.app.goo.gl/wowuqj3sRY5hcid37](https://maps.app.goo.gl/wowuqj3sRY5hcid37) **💸 Payment** Please pay as soon as you sign up: To keep things fair for everyone, if we don’t receive your payment within 48 hours, we will need to remove you from the participant list. If there’s a waiting list, this will happen sooner (in less than 48 hours). If that happens, no worries — you’re always welcome to sign up again if there’s space. 🌟 Early Bird Deal!
