val save_output : t ‑> Expect_test_common.Std.File.Location.t ‑> unit Config.IO.t
Collect the output that has been run since the last call to save_output
, or
since the current expect-test started running.
This function should only be called while a test is running. It is meant to be called as a result of ppx_expect translating an expect-test, and is not intended to be called manually.
