subject | fact |
regression testing | has definition The process of re-testing the a system, using a selected subset of test cases, after changes are made | |
has purpose to test software again once some defects have been fixed in case new defects have been inadvertently added | ||
is a subtopic of 10.9 - Strategies for Testing Large Systems | ||
is a kind of testing performed by software engineers | ||
tests a subset of the previously successful test cases because it tends to be far too expensive to re-run every single test case every time a change is made to software | ||
testing | can find defects whose consequences are obvious but which are buried in complex code, and thus will be hard to detect when inspecting | |
involves thinking of what could go wrong without actually studying the software | ||
is complementary to inspecting | ||
requires attention to detail | ||
process | see also process^2 |
