Some cases to cover -

different namespace
non-existing entity
size checks
change publisher

search - full word, prefix, key, key:value, tag

lineage exact time limits
multiple runs lineage
lineage run metadata (multiple runs, different tags)

add metadata for a app, delete all metadata for a app, and add again, and verify run metadata

All kinds of apps - Flow, Mapreduce, Worker, Service, Spark, Workflow, etc.
All kinds of data - Datasets and streams.
