// Run this using:
//   go test -tags=alltests -run=Suite -coverprofile=cov.out
//   go tool cover -html=cov.out
//
// Because build tags are a build time parameter, we will have to test out the
// different tags separately.
// Tags: x codecgen safe appengine notfastpath
//
// These tags should be added to alltests, e.g.
//   go test '-tags=alltests x codecgen' -run=Suite -coverprofile=cov.out
//
// To run all tests before submitting code, run:
//    a=( "" "safe" "codecgen" "notfastpath" "codecgen notfastpath" "codecgen safe" "safe notfastpath" )
//    for i in "${a[@]}"; do echo ">>>> TAGS: $i"; go test "-tags=alltests $i" -run=Suite; done
//
// This only works on go1.7 and above. This is when subtests and suites were supported.
