Chan et al. [4] (2009) proposed a few test data adequacy
criteria (e.g., evaluating each predicate in their graph
modeling to true at least once) to assure the quality of an
application. This paper is affiliated with China. Their work
proposed domain-specific test adequacy criteria to address
test challenges at the SaaS layer, which is a testing topic not
studied by any paper in PS. This work has been cited by
[S6][S17] (2011), [S18] (2010) in PS and one [9] of the two
papers we identified from Google Scholar as mentioned
toward the end of Section II.C.
