So, today the developer in the other company got such an understanding of the service that he started suggesting changes. A lot of changes in the DTD etc. These changes would imply some changes in the architecture downwards in the system. It is quite scary to start tearing things apart, when you already got something working. That is, if you don’t have a large amount of unittests.

Luckily I had good unittest coverage. So changing stuff was really just a matter of changing the tests, do fit the proposed changes. Test to see where I needed to change something. Do the changes and run the tests again.

It feels very good to have proper knowledge that everything actually works properly after a refactoring like this.

Unit testing is like love. It’ll keep you going when everything else fails. (citation)

Those who wait for something good … and so on

semi official

update:

Not that it means anything for us here in Norway. I’m hoping for a HSDPA or CDMA edition.

WeSIP is for SIP what Jboss, Tomcat and others are for HTTP.

For the uninitiated, SIP stands for Session Initiation Protocol, and is used to set up sessions for VoIP, games, IM and more. The SIP protocol is very similar to another successful protocol you might have heard of, http.
