Background: The fix-cache approach to regression

test selection was proposed to identify the most fault-prone files

and corresponding test cases through analysis of fixed defect

reports. Aim: The study aims at evaluating the efficiency of

this approach, compared to the previous regression test selection

strategy in a major corporation, developing embedded systems.

Method: We launched a post-hoc case study applying the fix-cache

selection method during six iterations of development of a multi-

million LOC product. The test case execution was monitored

through the test management and defect reporting systems of

the company. Results: From the observations, we conclude that

the fix-cache method is more efficient in four iterations. The

difference is statistically significant at α = 0.05. Conclusions:

The new method is significantly more efficient in our case study.

The study will be replicated in an environment with better control

of the test execution.efficiency of the regression testing based on these recommen-

dations has not been evaluated earlier.
