[test] Assert expected CCv2 return values by sfc-gh-bnisco · Pull Request #12689 · streamlit/streamlit

sfc-gh-bnisco · 2025-10-03T21:38:36Z

Describe your changes

Added tests for the BidiComponentResult class and its integration with SessionState. These tests verify:

The BidiComponentResult correctly merges state and trigger values and exposes the delta generator
Event callback parsing and trigger widget registration work as expected
SessionState properly merges CCv2 trigger values via the presenter
Presenter exceptions degrade gracefully without breaking SessionState access

Testing Plan

Unit Tests (Python): Added comprehensive test cases for BidiComponentResult and its integration with SessionState, including:
- Tests for attribute and mapping access in BidiComponentResult
- Tests for event callback parsing and trigger widget registration
- Integration tests for SessionState merging CCv2 trigger values
- Tests for graceful degradation when presenters raise exceptions
