redundancy by considering the above three lessons. However, other test experts
can also use our methodology to nd the redundancy of a test suite through
manual inspection. For instance, in the experiment of this work, the input test
suite was created by the developers of an open source project while the rst author
has performed the process of test redundancy detection.
A Collaborative Process for Redundancy
Detection
To systematically achieve test redundancy detection with lower false-positive error,
we propose a collaborative process between an automated redundancy detection
