I am still playing with the City Model plugin for Sonar made by eXcentia.<\/p>\n

For those who missed the previous episodes, you can find them here: City Model<\/a>, City Model \u2013 New release<\/a>, The ABC metric<\/a>.<\/p>\n

This plugin is really fun. And everyone finds fantastic a visual representation of the code in the form of a city. Going to the essential is important when you regularly assess the quality of applications.<\/p>\n

<\/p>\n

So I thought to a few simple but common cases, where its use will prove invaluable. This will also give me the opportunity to demonstrate how easy it is to set up.<\/p>\n

Critical City<\/strong><\/p>\n

A customer asks me an assessment of two applications. I dig a bit to know more precisely the ‘why’ of this audit. There may be several reasons, and I need to know a little more in order to accurately answer his request.<\/p>\n

For example: he wants to outsource these two quite old applications, and before making a call for tenders, he would like to know what is their quality level. It’s actually a good idea, which will allow him to better judge the offers that he will be presented and precise maintenance costs. Currently, many providers are willing to do anything to get a contract. Estimate the technical debt on these applications will allow him to reject ‘low cost’, unrealistic offers.<\/p>\n

Another case: the head of a development center is asked to take in charge the maintenance of an application. A rather complex one, at first sight: hundreds of thousands of lines of code, .NET proprietary frameworks, no documentation, etc. Enough to be a little bit suspicious. He would like to get some visibility on the quality of this application and the effort to be done before accepting. Or to get some information and good reasons to justify a refusal.<\/p>\n

In fact, the customer whom I speak had some problems with one of these ‘low cost’ providers who develop these two applications. Delays, budgets exceeded, many bugs and unhappy users, some crisis situations, the image of the IT diminished … In fact, he is looking for some reasons to explain to his provider he no longer wants him.<\/p>\n

Thus, I know how to go to the essential. Critical violations. Show him some good old critical bugs.

I set a Sonar code analysis from Jenkins. Very simple: Sonar \u2013 Jenkins plugin<\/a>. The analysis was quickly done.<\/p>\n

\"\"<\/a>Then, I launched my favorite Sonar dashboard, as an Admin :<\/p>\n

\"\"<\/a>I entered into the configuration page of the widgets and I added a City Model Top widget of eXcentia.<\/p>\n

Then, I changed the default values with the following parameters:<\/p>\n
