+"""Tests for ConversionService using realistic test data.
+
+This test module:
+1. Uses the CSV import tests to populate the in-memory database with realistic customer/reservation data
+2. Runs the XML conversion import endpoint with conversions_test_data.xml
+3. Asserts baseline match counts to detect regressions in matching logic
+
+The test data is designed to test realistic matching scenarios:
+- Matching by advertising campaign data (fbclid/gclid)
+- Matching by guest name and email
+- Handling unmatched conversions
+- Processing daily sales revenue data
