Talk:System integration testing

Isn't this the same as Integration Testing or are there moron bureacrats who view this as an extra step after I&T?

Can we replace the word "shakesdown" - I don't understand what it means. I'm not a software developer, but I've just come across a document on our intranet which shows Development --> SIT --> Regression so i wanted to understand what "SIT" and "Regression" means - and I can't fully understand what "shakesdown" means when refering to programming.

There is a distinct difference between Integration Testing (sometimes called Integration Testing in the small) and System Integration Testing (Integration Testing in the large). integration testing confirms that the units of a single system co-exist. Whereas System Integration testing confirms that multiple systems co-exist.

Once a system has been tested using a suite of tests there may be future releases. Regression Testing is the re-running of those previous tests to ensure that the system has not been regressed by any of changes.
