Even that I proposed the mission and got to play a little before the actual meeting, I think I got more knowledge about boundary testing and limits.
Everything will differ for a product and environment, but in this context I saw:
-a chat message goes through many locations. As we assumed (read the transcript) it will be probably be an Xml record at one point, then maybe a db record. Depending how the data stream is sent, we will probably have another set of limits.
-in testing limits we can actually do (without even trying) security testing or Pen testing. So we should be also careful from the legal points of view.
-the boundary depends on the input. An alpha numeric char differs from another char. An example used were kanji (Japanese) chars (“Petteri Lyytinen: I tried to paste a text string that is 32768 kanji characters” ..”only showed the two dots”)
-anything too big is truncated (or should be truncated in some situations) and the process of truncation can be different in some cases, some unexpected
-some parts cannot be tested easily (or in the required time interval) like the history containing large messages
-tools help – this time we used one available, but in other cases tools need to be built up
Thanks to the participants:
