val read_current_test_output_exn : 
  here:Base.Source_code_position.t ->
  Base.string

If there is an expect test running, perform a consuming read of the current output and return it without any sanitization or backtrace-checking. Note that this is different from the behavior of [%expect.output], which does perform sanitization.

If there is no test running, raise an error that includes here.

The name of the currently-running expect-test.

If there is no test running, raise an error that includes here.

val current_test_has_output_that_does_not_match_exn :

  Base.bool @@ portable

If the current test has reached a [%expect], [%expect_exact], or [%expect.if_reached] node whose output does not match the expected output, or if it has reached a [%expect.unreachable] node at all, returns true.

If the current test does not meet those criteria, returns false.

If there is no current test running, raises an error including here.

Push current output onto a notional stack. Until the output is popped, it will be excluded from read_current_test_output_exn.

val pop_output_exn : 
  here:Base.Source_code_position.t ->
  Stack_frame.t ->
  Match_or_mismatch.t @@ portable

Pop the top output stack frame, which must be the given frame. Returns Mismatch if the stack frame is not popped in the correct order.
