I keep spotting great MindMaps out in the wild. This one is by Santosh Tuppad on addons and types of tests you can use.
Software testing is so tricky as there is never the same or right answer for each situation or project. By collecting and referencing these resources and mindmaps we hope that you can take at least one useful thing away from each one. What you decide to do with that useful bit of information is entirely up to you!
