Module Expect_test_configSource

include Expect_test_config_types.S with type 'a IO_flush.t = 'a with type 'a IO_run.t = 'a
Sourcemodule IO_run : sig ... end
Sourcemodule IO_flush : sig ... end

A now-legacy monad. This signature used to declare a flush function. [%expect.output] still returns this type. No meaningful monadic work is done.

Sourceval run : (unit -> unit IO_run.t) -> unit

Run an IO operation until completion

Sourceval 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.

Sourceval sanitize : string -> string

sanitize can be used to map all output strings, e.g. for cleansing.

Sourceval upon_unreleasable_issue : [ `CR | `Warning_for_collector_testing ]

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.
