Testing and handoff matter when a product must continue without its original author. I protect high-risk journeys and leave a reproducible setup instead of chasing an arbitrary coverage percentage.

Priority areas are sign-in, money, permissions, transformations, migrations, and core integrations. Scope may include unit, contract, or end-to-end tests, CI, fixtures, README, environment diagrams, and troubleshooting guidance. Acceptance requires a new developer to start the project from instructions, tests to catch an intentional defect, no embedded secrets, and a release reproducible from a clean environment.

Acceptance criteria

Done when

  • Critical user journeys work end-to-end in staging
  • Roles and permissions match the agreed matrix
  • Repeated actions do not create duplicate entities

Deliverables

  • Source repo + deploy notes
  • Admin / operator access credentials
  • Short handoff checklist

Out of scope

  • Content writing and legal copy
  • 24/7 ops / on-call unless agreed

The final acceptance checklist is confirmed in the brief or contract; the list above is a scope alignment guide.

FAQ

Tap a question to expand the answer.

Must the entire legacy project be covered?

No. Start with changing and critical paths, then expand protection based on defect history.

Does handoff end support?

Not necessarily. It removes dependency; support can continue with your team, me, or both under an agreed arrangement.
