Mock Object Frameworks and CRC Cards Presentations

Today provided Mock Object Frameworks presentation with live coding session.

Looks like people prefers coding sessions over just presentation, so I shortened the introduction as much as possible.

I covered only the most important parts:

- why we use mock objects (a funny example was given);
- how to transform a system which can't be tested into a system which can be tested with using of mock objects
- types of mock objects: stubs and mocks themselves
- how to implement mock objects/stubs manually and with using of two major frameworks: Moq and Rhino Mocks.

I was thinking of providing one more mock object framework -- Microsoft Fakes -- but failed to do so. Some strange "Not supported" exception were thrown during "test ride" trying to raise an event from mock object. Furthermore, Microsoft Fakes framework distributed among VS 2012 Ultimate edition only, which is not suitable for the most of my listeners.

The next presentation will be about CRC cards. Will try to figure out how to conduct it in the most efficient way :)

Webinars

I think that seminars are useless in terms of learning how to conduct interesting presentation.

The main aspect of every presentation is auditory reaction. It's hardly possible to see that reaction while doing it in webinar-fashion way.

Two lectures provided last week

Two lectures provided last week:

- Event-Driven Architecture. It was the hardest one. I tried to explain this advanced topic to people, with  code example (Rhino Service Bus). As the result I may conclude that 2h is not enough for it. Will conduct once more, 4h-long this time.

The following example was used to describe event-driven system, and I am not sure if it was ok. Need to revise whole presentation.

- Introduction to UML. Actually, this was the easiest one. I spent about 5h to prepare it (a dozen of slides and a lecture plan). It was the nice one! :) Hope that it will be estimated with high scores! :)

The plan was simple: need to provide UML in scope which is widely used by developers.

I stressed that UML is useful for developers for communication purposes and provided UML in terms how to describe both static and behavior aspects of any system.

Static:
- class diagram
- deployment diagram
- component diagram

Dynamic:
- sequence diagram
- interaction diagram

Several examples were provided to establish connection between diagrams and codebase.

Event-Driven Architecture Presentation completed -- first round!

Провел презентацию Event-Driven Architecture, ушло 2 часа.

Подготовка заняла 16 часов.

Много примеров из жизни, но все же несколько сумбурно. Думаю, в следующий раз необходимо теоретические основы и примеры из жизни сократить до 40-30 минут, а вот практики -- побольше!

Обнаружилось, что присутствующим собственно эта практика в наибольшей степени интересна.

А вот послезавтра, 23 ноября, буду проводить новую презентацию, по UML - Introduction

Придется поработать над практическими примерами! :)

Надеюсь, все успею сделать как надо.

Why don't visit this event? It would be interesting! :)

Another TDD session is coming soon

Another TDD session is coming soon.

I prefer to gather not more than 10-15 listeners at the same time which gives me much more responsive auditory.

Feel exciting about it.

Let's bring some brightness to the world!

First ever BDD presentation in progress

Yesterday I provided the first part of BDD presentation.

It goes quite smoothly -- most of the people were quite responsive.

I represented BDD this way:

• revise SCRUM workflow and point out TDD place in it
• outline TDD "built-in" drawbacks (like Unit Tests != specification)
• introduce the idea that we can actually use specification as a base for our unit tests
• Reconsider testing as a whole -- we should test feature rather than a particle unit of code
• Point out that BDD specifications can be used for communication around all people involved into development process
• Implement a simple system (POS) as an example in BDD way (using SpecFlow .Net framework)

Yesterday I stopped on the last point -- it seems that 2 hours is engogh to provide BDD ideas, but not enough to show it in action.

Today will finish it.

BDD with SpecFlow Presentation

Tomorrow and a day after tomorrow I will be providing BDD Presentation.

Doing it at first time (not counting that small session done by my while I was working for Target Process), feel a bit nervous -- more than 20 people, current EPAM employees, will be here.

Good luck to me! :)

BDD Training Session

in two days I am supposed to lead the BDD training for EPAM employees.

There are about 70 people who already subscribed to it, so about 20 developers were chosen to participate in this session.

Need to spend a few hours on preparations :)

Consultant Career

From time to time I am thinking of Freelance Consultant career. May be in a few years I will be ready for it, but not now.

I am still not sure whether I am skillful enough to provide such trainings.

Would be nice to have a look at active consultants's blogs to see how they handle this job.

Helping to spread useful techniques

That's interesting thing: it's almost 5 months as I don't have any projects here, at my workplace.

Firstly there seemed to be a position on new project, but then it was decided not to introduce me.

It allowed me to apply my skills on codebase analysis but then I became available for another projects again.

So I decided to help out my company and proposed the following topics for training sessions I can teach:

Behavior-Driven Development in action Discover next evolutionary step in TDD – Behavior-Driven Development (BDD). In this training you’ll know how not to miss any of customer’s requirements and transform them into a form of executable specifications, which can be used for collaboration purposes between customers, QA and developers.

Test Driven Development in action this training is dedicated to the Test-Driven Development technique. How to not to spend much time on debugging? How to design convenient-in-use API for your class structure? This live coding session will answer two main questions: WHY every developer should be at least familiar with this technique and HOW it can be implemented in real code. NUnit will be used as a unit-testing framework.

Mock Object Frameworks in unit testing: how to use and when Those who familiar with TDD &pamp; BDD would like know how to practice it more efficiently: This live coding session will demonstrate how to test pieces of code in isolation of the rest code with using of mock object frameworks.

Event-Driven Architecture (EDA): Overview The training introduces in event-driven architecture principles. Contemporary world is event-driven, so often our software can be implemented using event-driven architecture principles in the most efficient way. When EDA can be applied? What considerations can be taken into account and how actually it can be implemented with using of real EDA framework – that questions will be answered here. NServiceBus EDA framework will be used for demonstration.

Introduction to UML Unified Modeling Language (UML) is a common language which is used for communication purposes among professional developers. How to share architecture? How to describe static structure or dynamic aspects – this presentation is all about it.

It's been a week as I am doing them.

It's interesting thing, but most people are interested in TDD. I supposed that it would not be so popular, but for now I have given two TDD sessions and one Mock Object Frameworks session.

Now I think that I will be spending my next couple of months (before I move to the USA) on that sessions, and I like it :)

P.S. I asked Vladzimir Tihon, the lead of .Net Lab here, at EPAM, whether his students need CRC card session, and he agreed that it would be nice.

I think that I need to prepare for it as well :)

Any more topics are welcome!
