Testing only the code of value

I am 99% sure I have had a post like this in the past, but my google-foo was weak today and I could not find it. Do not let anyone blow smoke up your back side, testing is expensive, testing takes time but most importantly testing can help improve...

Your unit test may smell if…….!

If you find yourself using reflection in your unit test to push 'stub’ data into it your test just may smell. Now there are times (especially when dealing with legacy code) that you need use reflection to crack open a class to push/pull values...

Quantity is NOT a measure of Quality

Today I was asked what I thought about asking each of our feature teams to report the total number of new unit tests created during their iteration. My knee-jerk reaction was to ask the person WTF were they thinking. However, my better sense...

Tests are not ‘Tasks’ you put on a backlog…

Today I had a conversation with our ‘scrum of scrum’ masters (we have 7 different scrum teams on our product team of 60+) and he asked me why someone would provide ‘developer tests’ as a task for the backlog? Before I go any further, this is NOT a bait...

Throw away and rebuild or refactor from within

The other day on Twitter there was a stream whether it is better to completely scrap an applications code base and start over, or refactor from within. Now I do want to state right now: The information here is based on my experiences and is simply...

Teaching someone to test using an Isolation Framework

Part of my job at work is to teach and mentor other developers on our team. Right now I am in the process of teaching two of our developers how to create unit tests (notice I did NOT say integration tests because most anyone can do those). We are also...

Testing is hard but debugging just sucks A$$

In my last post ( here ) I was giving a wrap up of the Mocking session I recently did at TriNug . In that post I gave some of the reasons (sorry, I meant excuses) people gave for not doing any type of automated testing during their dally development ritual...

They all have one thing in common.....

Test first Test during Test after Answer, Test. No matter what style of testing you believe in, they all share one common trait. They all test your code. So, what is the point of this post you may ask? Simple. To me, it does not matter how your tests...

Sound of one man testing

Recently I was chatting with a friend of mine and he asked if a single developer could be successful following TDD on a team that does not follow TDD. My simple answer was YES, they can. But there are a few things you must consider..... How can they make...

Whitebox vs Blackbox testing (location of unit tests)

Over on the Alt.Net mailing list ( here ) the topic of where to put your unit tests was the hot topic a few days ago. This is a topic that I have debated with various people over the past few years. With all the debates I have had, it is clear to me that...

What is a name, besides identity?

Over the past 2-3 days there has been an uproar over at the altnetconf list. Oops, I meant the cli_dev list. This uproar is because of a single action. Changing the name of the list. Some would like to argue that the name of the list is not important...

Backing in Unit Tests into an existing project

Recently I was asked about backing in unit tests into an existing project. In particular I was asked A) was possible and B) is it worth it. In short my answers to both these are Yes and Yes. However, backing in unit tests is not without its challenges...

Why I believe IN and WRITE unit tests

In my last post I think I struck a cord with some people in my post 'Unit tests taking too much time'. My intent was NOT to sound like an elitist Agilist or any else of that nature. My intent was simply to put a post out there about the misperception...
