Day 139: How do you think like a tester?

Well - that I try to figure out. How do you think like a tester? Especially now when I am no longer tester but methods expert working with testing methods. Luckily there is lot of material available to read - I love to read and learn. One of my favorite material (and also material for course I am participating next week) is this by James Bach and Michael Bolton. I have already participated course "Rapid Software Testing" with Michael Bolton and this time it will be James Bach teaching me "Critical Thinking for Software Tester". Looking forward for that! Those two guys are gurus in testing business.
