class RSpec::Core::ExampleStatusMerger
Merges together a list of example statuses from this run and a list from previous runs (presumably loaded from disk). Each example status object is expected to be a hash with at least an ‘:example_id` and a `:status` key. Examples that were loaded but not executed (due to filtering, `–fail-fast` or whatever) should have a `:status` of `UNKNOWN_STATUS`.
This will produce a new list that:
- Will be missing examples from previous runs that we know for sure no longer exist. - Will have the latest known status for any examples that either definitively do exist or may still exist. - Is sorted by file name and example definition order, so that the saved file is easily scannable if users want to inspect it.
