Why should we care about test dependence?
Code snippet
Makes test behaviors inconsistent
Affects downstream testing techniques
Test prioritization
Test selection
CPU 2
CPU 1
Test parallelization
General algorithm to nullify test dependence …
A test suite
Reordered/Amended test suite
Known test dependences
Known test dependences:
-Can be generated through approximate algorithms [Zhang et al. ISSTA’14] or empty
-Reuseable for different testing techniques and when developers change their code
A test suite:
-Product of test prioritization, selection, parallelization
