The effectiveness of the criticality-complexity matrix for regression testing

Each of us, who are involved in regression testing, continually confronts with the question "How to test the new version of the software in a time-limited environment to provide the necessary level of quality control", as well as the task of determining the density of the test coating. We apply the practice of using the criticality-complexity matrix to answer these questions.

In the course of the report, we will consider: what is the matrix of criticality-complexity; what is it for; an example of its use and the results from its implementation.
