Why your test coverage is never going to be 100%...

Yet again MS Research has proven to provide interesting and nice paper. In this article they describe dependencies between test effort, test coverage and post-release defect inflow.
It is interesting to note that the effort grows exponentially with test coverage while the post-release quality only linearly. I will recommend that to my students who often ask about the cost of quality....
Looking forward to more research from MS.
