1. Start from a clean browser
- Use a private profile with no existing consent cookies.
- Clear site storage between scenarios.
- Disable extensions that alter tags, cookies or requests.
2. Verify the initial timeline
- Confirm the default command runs before config and event commands.
- Check that all required consent types have explicit values.
- Inspect the first requests before interacting with the CMP.
3. Test every choice
Accept and reject
Confirm each choice creates the expected update and request behavior.
Revisit and withdraw
Confirm saved state is restored and later changes remove or restrict identifiers as designed.
4. Capture evidence
Keep screenshots or exports from GTM preview, Tag Assistant, the data layer, storage and network panels. Evidence makes regressions much easier to diagnose after releases.
