Test a browser storage migration with old tabs still open
Exercise upgrades, interrupted writes, quota errors, and mixed application versions.
Readiness check
Is the handoff ready?
Use this table before you send the first ticket. Fix the weak spots while access is still limited.
| Area | Ready | Needs work |
|---|---|---|
| Question | One observable browser storage migration outcome | A request to inspect the whole system |
| Fixture | disposable profiles seeded with each supported schema version | Customer data or shared credentials |
| Evidence | browser, tab build, schema version, migration step, error, counts, and reopened state | A pass label without observed values |
| Approval | The product owner approves data-loss behavior and release sequencing. | The contractor changes production alone |
Reproduce the browser storage migration failure safely
An old tab can write stale data after a new tab migrates the store. Start with one case that can fail without touching customer records or production infrastructure. Write the expected result, stop condition, and reviewer beside the fixture.
Use disposable profiles seeded with each supported schema version. Label every identity and artifact so a reviewer can distinguish test evidence from a live record.
Leave enough evidence for a second person
Capture browser, tab build, schema version, migration step, error, counts, and reopened state. Include the source revision and test time. If behavior changes between runs, retain both results.
The product owner approves data-loss behavior and release sequencing. A remote programmer can prepare the fixture, run bounded checks, and explain the result. New policy, privileged access, and release approval stay with the named owner.
