Upstream: hedgehogqa#454
Using environment variables, this lets the user either
HEDGEHOG_SKIP_TO_TEST
: Start testing at a specific test number, and then continue from there. If it fails it'll shrink, if it passes it'll move on to the next test. Or,HEDGEHOG_SKIP_TO_SHRINK
: Test at a specific test number and shrink state. If it fails it won't shrink further, if it passes the test will pass. The shrink state is encoded as an alphanumeric string and printed below the test and shrink counts. It also runs the test at intermediate shrinks, ignoring the results; see discussion on the upstream PR.Environment variables are a bad way to handle this, but it means we can use the feature now without also forking hspec-hedgehog.
