Synopsis

Running Individual Properties

check :: MonadIO m => Property -> m Bool Source #

Check a property.

recheck :: MonadIO m => Size -> Seed -> Property -> m () Source #

Check a property using a specific size and seed.

Running Groups of Properties

data RunnerConfig Source #

Configuration for a property test run.

Constructors

RunnerConfig
Fields runnerWorkers :: !(Maybe WorkerCount) The number of property tests to run concurrently. `Nothing` means use one worker per processor. runnerColor :: !(Maybe UseColor) Whether to use colored output or not. `Nothing` means detect from the environment. runnerVerbosity :: !(Maybe Verbosity) How verbose to be in the runner output. `Nothing` means detect from the environment.

checkParallel :: MonadIO m => Group -> m Bool Source #

Check a group of properties in parallel.

Warning: although this check function runs tests faster than checkSequential, it should be noted that it may cause problems with properties that are not self-contained. For example, if you have a group of tests which all use the same database table, you may find that they interfere with each other when being run in parallel.

Using Template Haskell for property discovery:

tests :: IO Bool
tests =
  checkParallel $$(discover)

With manually specified properties:

tests :: IO Bool
tests =
  checkParallel $ Group "Test.Example" [
      ("prop_reverse", prop_reverse)
    ]

checkSequential :: MonadIO m => Group -> m Bool Source #

Check a group of properties sequentially.

Using Template Haskell for property discovery:

tests :: IO Bool
tests =
  checkSequential $$(discover)

With manually specified properties:

tests :: IO Bool
tests =
  checkSequential $ Group "Test.Example" [
      ("prop_reverse", prop_reverse)
    ]

checkGroup :: MonadIO m => RunnerConfig -> Group -> m Bool Source #

Check a group of properties using the specified runner config.
