Make the expectation explicit
Define the product outcome once, then review platform-specific setup and assertions. Use the correct app build and a stable test account for each device.
Put it into practice
Organize the related cases in AuraCheck and run with the appropriate local tooling. Review evidence independently for each platform before claiming cross-platform coverage.
Try this on your next release
Choose one journey, define the expected result, and inspect the evidence from a completed run. Expand the suite after the first test is useful.
