I've just started work in a development team that has recently adopted scrum processes. Part of my initial tasks were centred around the implementation of a test process that works within scrum.
Here are a few links that will help you on your way to discover the delights of agile testing:
- A good intro to agile testing practcies from google's Elizabeth Hendrickson
- Agile Software Development - Agile Testing blogs
- Agile testing principles - Elizabeth Hendrickson
- Extended agile test resources
Even if you're not moving towards agile development practices, some of the techniques, tools, and practices referenced in the above links can greatly improve the productivity and reputation of the tester as valuable member of the development team. Take a look.
