Module Async.Expect_test_config

module IO : sig ... end with type 'a t = 'a Deferred.t

IO monad

val flush : unit ‑> unit IO.t

Flush whatever need to be to get pending output out on file descriptor 0.

val run : (unit ‑> unit IO.t) ‑> unit

Run an IO operation until completion

val flushed : unit ‑> bool

Synchronous check that there is no pending output on file description 0. With async, there is no guarantee that on the rhs of a IO.bind (flush ()) ... the output is completely flushed, that's why we need this.

val upon_unreleasable_issue : Expect_test_config.Upon_unreleasable_issue.t

upon_unreleasable_issue specifies how to deal with output that should not be released even if it is accepted (e.g. backtraces). The default is `CR.
