Back to the testing quadrants: which tests can be found in quadrants 3 und 4?
The third quadrant is dedicated to the explorative, manual tests which look at user acceptance. And last but not least, in the fourth quadrant, one takes a look that the Load and Performance and Security Tests. In the Security Tests, we recreate the active attempt to hack the software. In Load and Performance Tests, a large user load is simulated in peaks that have been previous determined.
