From 4513d306d85bf440543687a576009dafe26cefd3 Mon Sep 17 00:00:00 2001 From: jedarden Date: Tue, 28 Apr 2026 14:41:27 -0400 Subject: [PATCH] test(replay): add comprehensive unit tests for session replay export Added 49 tests covering all export/import functionality: - JSON export/import with validation - Base64 export/import with special character handling - URL generation and extraction - Markdown export with all sections - Filename generation - Metadata calculation - Round-trip integration tests Verifies the export functionality is complete and working correctly for all three formats (JSON, Markdown, URL) in both TUI and web UI.
