I have seen Deep-Link Routing treated like a formality and like a real craft. One produces green statuses, the other produces confidence people can explain.
My checklist for Deep-Link Routing is not meant to turn testing into box-ticking. It exists so pressure does not erase the few important questions that protect entry state, auth handoff, and landing users in the right place with the right context. It gets expensive when the link opens the app, but the user lands in a dead end because one precondition was missing.
A good checklist keeps important risk visible when the room gets busy.
Before I Start
- Make the change area explicit
- Write down the most expensive failure in one sentence
- Confirm which marketing, product, and the users arriving from outside the app should review open risk
- Choose the environment that will tell the truth fastest
During the Check
- Exercise the normal path that should protect entry state, auth handoff, and landing users in the right place with the right context
- Run an awkward-path example based on a marketing link works for signed-in users and fails for everyone returning through an expired session
- Watch for mismatches between visible success and hidden state
- Capture the one detail that will matter during sign-off later
Before I Close the Work
I finish by asking whether the evidence would still make sense to someone who was not present during testing. For this topic, the evidence I want usually looks like route-state checks, auth fallback behavior, and proof the target screen still makes sense after redirects.
If the answer is yes, the checklist did its job. If the answer is no, I am not done yet. That is usually when confidence becomes visible enough to share, not just feel.
