Strengthening Open Source's Weakest Link
Pop quiz: If one open source user tests 30 percent of an application, and another tests 20 percent, how much of the application has been tested?
The answer is probably closer to 30 percent than 50 percent, since both users probably focused on common functions like start-up, shutdown, and data access. The problem gets amplified if the application is built for n-tier deployment based on service-oriented architecture. newspapers and broadcasters. The service handles between 150,000 and 500,000 pages of content per affiliate per day, supporting 11,000 concurrent users. MySQL, a free open source database, has been the backbone of AP Hosted News since 2002.
Everyone knows that the cornerstone of open source software is the free availability of its source code, which lets developers and users around the world contribute to it and improve it. The software naturally becomes stronger as it accumulates improvements and sheds imperfections. The quality improves based on more usage and reviews.
But the model breaks down when it comes to making sure the software actually works in real-world deployment scenarios. The power of participation has been confined almost entirely to the development phase of the software life cycle. Testing remains open source's weakest link as it is difficult to reproduce all intended usages.
