Kashif Ali posted a good comment on our blog post from last week, "What makes a good QA engineer / tester?" In his comment, he linked to four more good blogs on the subject.
The Google Testing Blog is decent. It has multiple authors, as with most Google blogs. The posts are not very frequency: once every week or two is typical. But then they tend to be longer, more essay-like. Personally, I prefer multiple shorter posts, but that's just me.
Jonathan Kohl writes Collaborative Software Testing, which I really like. It focuses on the toughest issues around testing, which are teamwork and process. Most testing blogs focus on technical tools and tips. Those are fine, but I usually don't find those to be the hard parts. The posts are still long and essay-style, but I enjoy them a lot.
James Bach writes The Consulting Software Tester. He is an experienced, known software development "guru." He blends short quips with longer essays, which is nice, and he also quotes / links to more external resources than the other blogs. Personally, I find a really good insight, a gem, about once every five posts on this blog. It's worth reading for those alone.
The last blog on this list is The Thinking Tester, by Shrini Kulkarni. James Bach, for one, is a fan. I only recently stumbled upon this blog, so I don't know it well yet. But it seems like the author has mostly moved from longer blog posts to Twitter. He's @shrinik there, for the curious.
All of these, along with my original favorite, Abakas, make for valuable reading. Even as an agile, light-QA guy, I really enjoy them.
Do you have other favorite blogs in this area? Or online QA resources in general?
