Ask HN: How can QA people contribute top open source projects?

My wife is looking for a QA job...but she needs practice before she can go out and attend interviews. What are some good open source QA projects she can participate in?

Also, if you are in Bay area and willing to give QA work on Java and/or Selenium so she gets some practice, I will be grateful. Pay would be appreciated but not necessary. She has about 2 years experience in QA for working for EMC2.
