If you are building a test suite, you don't need these functions.
They may be used by other tasty add-on packages (such as tasty-hspec).

Defined in Test.Tasty.QuickCheck Methods run :: OptionSet -> QC -> (Progress -> IO ()) -> IO Result testOptions :: Tagged QC [OptionDescription] | |
optionSetToArgs :: OptionSet -> IO (Int, Args) Source #
Convert tasty options into QuickCheck options.
This is a low-level function that was originally added for tasty-hspec but may be used by others.
