Here are some worthy things I came up against in the last few days…
1. Quick Testing Tips website features short quick tips with links in different areas. Good link to follow and contribute to.
2. In case you need some time-management tips try the Pomodoro technique. The informative PDFs are available as free download.
3. For tracing the before and after changes to Registry use the WhatChanged tool.
4. The Oblique Strategies are suggested by Michael Bolton in case you run out of Test Ideas. Try it.
