Test missing and duplicate inputs deliberately before an automation handles live work. Decide what each case should do, run it in a safe test environment, and inspect the resulting records or actions. A normal successful run does not prove that repeated or incomplete requests are handled safely.
Define the expected result first
For each required input, identify whether the workflow should stop, ask for clarification, or use an explicitly approved default. Avoid silently substituting information that changes the meaning of a request.
For example, an invented internal scheduling workflow might require a confirmed date. A missing date should not become an arbitrary appointment time. Specify who reviews that exception and how they can see that the task did not complete.
Build a small test set
- A complete valid request.
- A request missing a required field.
- A value in an unexpected format.
- The same request submitted again.
- A retry after part of the process has already completed.
- A downstream service failure.
Use test records and controlled destinations. Keep payment, external messaging, and sensitive-data actions disconnected unless the responsible team has explicitly approved a safe testing arrangement.
Inspect side effects, not just the success label
Check whether the result exists, contains the correct information, and appears only as intended. Look for extra records, repeated messages, or a half-completed action hidden behind a green status.
Microsoft's flow-testing guidance warns that resubmitting a run can create duplicated data or emails. Do not assume a retry is harmless merely because the first run reported an error.
Decide how duplicates will be recognized
Use a reliable request identity where your tool and process support it. Clarify whether a second submission represents the same request or an intentional new one. Comparing a person's name alone may confuse distinct pieces of work.
The exact implementation depends on the tools and data model. Check current documentation and test the actual configuration; this article does not provide a universal duplicate-prevention setting. If you cannot determine whether an action already happened, stop and reconcile rather than blindly replaying it.
Keep the test evidence
Record the input case, expected behavior, actual result, and any change you made. Repeat the affected tests after changes. Give an owner responsibility for deciding whether the results are safe enough for live use.

A safer readiness check
Test ordinary runs and exception paths, then inspect their real effects. Missing data and duplicates need defined behavior, not optimism. An unresolved outcome is a reason to investigate before proceeding.
