Start with structural evidence
Confirm the expected database objects and required dependencies in the isolated target. Review restoration warnings and ownership or permission differences. A process exit code is one observation; it does not explain whether missing objects are harmless, expected or a failed recovery.
Choose representative behavior
Use approved test cases for the important reader or operator tasks. An application can connect successfully while an attachment, search index or permission boundary remains broken. Keep the expected result beside each case so another reviewer can understand why it passed.
Avoid misleading shortcuts
Matching row counts alone do not establish data correctness. A checksum can verify a specific file transfer without proving the database is logically usable. Choose checks appropriate to your system, record their limits and preserve failures. Do not claim universal validation from a few sample records.
Use three outcomes
Pass means the predeclared condition was observed. Fail means it was tested and not met. Not tested means there is no result. This distinction prevents an incomplete rehearsal from becoming a reassuring green checklist. Resolve critical untested conditions before relying on the claimed recovery path.
Prepare a small explicit acceptance table
Fictional cases: approved sample order is readable; its attachment opens; the expected test role cannot read a restricted record; no real notification is delivered. For each case write expected behavior before running the exercise, then capture the observed outcome and evidence reference. A failed permission check can matter even if all documents appear intact. Keep the sample’s limits explicit: four cases cannot establish that every record and workflow is correct. Expand the pack when a new dependency or a previous failure demonstrates a missing test.
