Wait on expected conditions

waitUntil :: SessionState m => Double -> m a -> m a

Wait until either the given action succeeds or the timeout is reached. The action will be retried every .25 seconds until no ExpectFailed or NoSuchElement exceptions occur. If the timeout is reached, then a Timeout exception will be raised. The timeout value is expressed in seconds.

waitUntil' :: SessionState m => Int -> Double -> m a -> m a

Similar to waitUntil but allows you to also specify the poll frequency of the WD action. The frequency is expressed as an integer in microseconds.

waitWhile :: SessionState m => Double -> m a -> m ()

Like waitUntil, but retries the action until it fails or until the timeout is exceeded.

waitWhile' :: SessionState m => Int -> Double -> m a -> m ()

Like waitUntil', but retries the action until it either fails or until the timeout is exceeded.

Expected conditions

data ExpectFailed

An exception representing the failure of an expected condition.

Instances

Eq ExpectFailed

Show ExpectFailed

Typeable ExpectFailed

Exception ExpectFailed

expect :: MonadBaseControl IO m => Bool -> m ()

An expected condition. This function allows you to express assertions in your explicit wait. This function raises ExpectFailed if the given boolean is False, and otherwise does nothing.

unexpected :: MonadBaseControl IO m => m a

throws ExpectFailed. This is nice for writing your own abstractions.

Convenience functions

expectAny :: MonadBaseControl IO m => (a -> m Bool) -> [a] -> m ()

Apply a predicate to every element in a list, and expect that at least one succeeds.

expectAll :: MonadBaseControl IO m => (a -> m Bool) -> [a] -> m ()

Apply a predicate to every element in a list, and expect that all succeed.

(<||>) :: Monad m => m Bool -> m Bool -> m Bool

Lifted boolean or

(<&&>) :: Monad m => m Bool -> m Bool -> m Bool

Lifted boolean and
