smallCheck :: Testable a => Depth -> a -> IO ()Source
Run series of tests using depth bounds 0..d, stopping if any test fails, and print a summary report or a counter-example.
smallCheckI :: Testable a => a -> IO ()Source
Interactive variant, asking the user whether testing should continue/go deeper after a failure/completed iteration.
Example session:
haskell> smallCheckI prop_append1 Depth 0: Completed 1 test(s) without failure. Deeper? y Depth 1: Failed test no. 5. Test values follow. [True] [True] Continue? n Deeper? n haskell>
depthCheck :: Testable a => Depth -> a -> IO ()Source
Same as smallCheck
, but test for values of depth d only
smallCheckPure :: Testable a => Depth -> a -> Either [String] (Integer, Integer)Source
A pure analog of smallCheck
.
If a counterexample is found, it is returned.
Otherwise, a tuple of two numbers is returned, where the first number is the number of all test cases, and the second number is the number of test cases that did not satisfy the precondition.
