TDD – commit by commit String Calculator Kata (III) Posted on by Michal Franc Previous post in the series – TDD – commit by commit String Calculator Kata (II) In the previous post I did a cleanup phase and added one feature to the String Calculator. The kata is not finished yet.Step VIII – Different Delimiters String Calculator should support different delimiters. Previous solution was just a hard-coded hack, still it was good enough solution. There wasn’t any requirement that would suggest a need f...

TDD – commit by commit String Calculator (I) In this series I want to share my approach to TDD. I will do a simple TDD kata, sharing with you all my decision and thoughts. It’s called commit by commit beacuse you will find here links to github with each step. There will be a commentary to each one of these. I encourage you to comment and show me the flaws in my “style” of TDD coding. I also want to learn from you. I do know that my approach has its problems and there is allways a wayt to do something b...

In the project, I am working with, there is a simple feature that imports data from external source. Import is only interested in new records. This condition is fulfilled with ‘DateTime’ comparision. Looks simple, Unfortunately I have encountered a nice ‘bug’.

I have been playing with Node.js recently. Mostly doing some small hobby projects. One of them needed server side badly, some of the cool features were not possible with the client side only web app. I was thinking about using RoR, Asp.Net Mvc or NancyFX all of these frameworks suitable for the task. Then why Node ? Well, the answer is simple, FUN. There is a lot of hype around it. Community is very dynamic, lots of modules and extensions created on the daily basis. As a Passionate Developer, I also wa...

This post will be a little note with steps needed to setup a working CouchDb instance on windows machine.NoSql RDBSM rules the world, it is still a “standard” in the industry. My first Database was used inside a simple rss client written in C. This was the weird world of C programming with weak documentation and Segmentation fault errors everywhere. Now, I am mostly using MSSQL with ORM support ( NHibernate ), but there is another world of databases on the horizon, NoSql movement. There have been a lot...

Finally i got my personal ...

In previous post, I defined a good unit test as one that:tests single unit of workcontains only one assertis self contained Presented sample of code with one unit test, unfortunately had two asserts. Clear violation of the second rule. One of the fellow bloggers MJ pointed out this mistake. It is time to “fix” it and talk about “Only one assert per test” rule.Why only One Assert There are couple of problems with multiple asserts.Unit Test Misinformation Frameworks like NUnit do notify about failing un...
