Test-induced design damage or why TDD is so painful
I’m going to write a couple of posts on the topic of TDD. Over the years, I’ve come to some conclusions of how to apply TDD practices and write tests in general that I hope you will find helpful. I’ll try to distil my experience with it to several points which I’ll illustrate with examples.

Test-induced design damage or why TDD is so painful
Encapsulation revisited
The third most important software development principle is Encapsulation.
KISS revisited
Today, I’m going to discuss the KISS principle. I consider it the second most valuable software development principle.
YAGNI revisited
I’m starting a new blog post series about the most valuable principles in software development. Not that I think you might not know them, but I rather want to share my personal experience and thoughts on that topic. The order in which I put those principles reflects their significance relative to each other, as it appears to be in my opinion.
That is quite a large subject and I’m going to dilute it with articles on other topics, so it might take a while.
Okay, let’s start.
Make hard-coding your default choice
Hard coding is often considered an anti-pattern. Having values that can change over time hard-coded in the source code requires recompilation every time these values actually change. While this statement is true, I think that hard coding should be the default choice when developing an application. Hard coding vs configuration file When you work on a project or feature, there always are some magic numbers or strings that potentially can change in future.
Interfaces vs Interfaces
Today, I’d like to discuss the differences between interfaces, abstractions and .NET interfaces, as well as what the term "implementation details" means.
Return the most specific type, accept the most generic type
I guess most developers heard the guideline stating that, when designing methods, you should return the most specific type and accept the most generic one. Is it always applicable? Let’s try to look at it from different perspectives.
3 misuses of ?. operator in C# 6
I guess you already know about the safe navigation operator (?. operator) coming up in C# 6. While it’s a nice syntactic sugar for quite a few cases, I’d like to point out some misuses of it I’m sure we will see when C# 6 is released.
Combining SQL Server and MongoDB using NHibernate
We often think that relational and NoSQL databases are somewhat incompatible. But what if we could use both within a single domain model? I’d like to show how to combine SQL Server and MongoDB together and discuss what benefits we could get from it.
Validation logic and NHibernate event listeners
Today, I’d like to discuss a particular case with validating input data using NHibernate event listeners.
