Java quality's open-source tools

Hello again.

Since I posted my first article here I've been asked a number of times: "Why there's no open source tools for quality process? Are there any?"

Being a lazy enough, I decided to reply just once in this public forum. Ok, here's the answer:
there's a number of open source tools to do a neat automation of one's software quality process.

To schedule and execute jobs execution in a heterogeneous environment you might want to use
• Sun's donated project RIO
or
• Sun's opensourced GRID engine
instead of Distributed Tasks Framework, we wrote.

and to run actual tests
• Tonga harness can be replaced with JTiger or TestNG

I encourage you to look around and find a tool, fits your needs in a best way possible. Enjoy,

Yours,
Cos
