Open source is of better quality than proprietary software
All told, Coverity analysed over 37 million lines of code from 45 of the most active open source projects of 2011 and also examined 3 open source projects in depth: Linux 2.6, PHP 5.3 and PostgreSQL 9.1. Coverity’s survey reached the following key findings from these analyses:
- Open source projects that build development testing into their process reap the benefits of continued quality improvement over time.
- Open source projects of all sizes can successfully adopt development testing, but quality must be measured as a function of codebase size and developer community.
