Compare what was read back against what was asserted

The criterion is the re-read, never the return value: in the spike four cases out of four reported success while three had done something else. A missing row is the loudest failure and must not read as nothing to compare.

Usage

compare_readback(expected, actual)

Arguments

expected

Named list of the asserted fields.

actual

Named list read back, or NULL when no row came back.

A list with conforms and differences.
