1. Prepare
Define a representative input and the expected outcome before running the test.
Test the standalone @sap/approuter 23.0.0 route subset locally with first-match evidence.
No destination is contacted and no connectivity is attempted. Unsupported properties are shown but not guessed.
Practical usage guide
Test xs-app.json route order, regular-expression captures, target rewrites, methods and sanitized destination names locally.
Define a representative input and the expected outcome before running the test.
Inspect the actual result, cover at least one edge case and keep enough input detail to reproduce any failure.
Confirm service version, destination and tenant-specific constraints before applying the result in BTP.
