your process unless it's automated, and part of an automated continuous integration process. Here's why: SCM is about identification and reproducibility and manual processes are error prone. While manual testing is better than no testing, an automatic, repeatable, testing process is the best way to ensure that your testing process helps to validate your configuration.
If testing is part of SCM process, who's responsible for testing? The reality is that the various roles on a software project need to work together for the project to be successful. Everyone has a role in the testing process. The good news is that, by it's nature, testing will help you to understand how well everyone is working together.
We want to emphasize that that testing is effective when it is understood to be a shared responsibility, as everyone benefits from an effective testing strategy. Testing can start with a developer (unit testing), and/ or a QA engineer (integration testing), but the activities need to be supported by the build and release engineers to allow for frequent running of tests as part of the build and correct association of tests results with builds.
Testing is a cornerstone of agile practices because testing helps provide the feedback that enables agile to work. As we said in our October column, citing Susan Dart, SCM is about ensuring the integrity of a product and making its evolution more manageable. Testing is a mechanism that provides the feedback necessary to ensure product integrity and manage change effectively. Testing is part of the foundation of SCM.
