Abstract—Background: History based regression testing was
proposed as a basis for automating regression test selection,
for the purpose of improving transparency and test efficiency,
at the function test level in a large scale software development
organization. Aim: The study aims at investigating the current
manual regression testing process as well as adopting, implementing
and evaluating the effect of the proposed method.
Method: A case study was launched including: identification of
important factors for prioritization and selection of test cases,
implementation of the method, and a quantitative and qualitative
evaluation. Results: 10 different factors, of which two are
history-based, are identified as important for selection. Most
of the information needed is available in the test management
and error reporting systems while some is embedded in the
process. Transparency is increased through a semi-automated
method. Our quantitative evaluation indicates a possibility to
improve efficiency, while the qualitative evaluation supports the
general principles of history-based testing but suggests changes
in implementation details.
