There is a growing body of knowledge in the computer science, software
engineering, software testing and software test automation disciplines.
However, there is a challenge for researchers to evaluate their research
findings, innovations and tools due to lack of realistic data. This paper
presents the Westermo test results data set, more than one million verdicts
from testing of embedded systems, from more than five hundred consecutive days
of nightly testing. The data also contains information on code changes in both
the software under test and the test framework used for testing. This data set
can support the research community in particular with respect to the regression
test selection problem, flaky tests, test results visualization, etc
