quickCheck :: Testable prop => prop -> IO ()Source

Tests a property and prints the results to stdout.

quickCheckWith :: Testable prop => Args -> prop -> IO ()Source

Tests a property, using test arguments, and prints the results to stdout.

quickCheckResult :: Testable prop => prop -> IO ResultSource

Tests a property, produces a test result, and prints the results to stdout.

quickCheckWithResult :: Testable prop => Args -> prop -> IO ResultSource

Tests a property, using test arguments, produces a test result, and prints the results to stdout.
