Added two new integration test files:
1. cache_stats_integration_test.rs (g3-core)
- Tests CacheStats accumulation through streaming completion flow
- Verifies cache hit detection (cache_read_tokens > 0)
- Tests multi-request accumulation of cache statistics
- Verifies cache efficiency and hit rate calculations
- Uses MockProvider to simulate provider usage data
2. gemini_serialization_test.rs (g3-providers)
- Tests Gemini API message format conversion
- Verifies system messages become system_instruction
- Verifies assistant role maps to "model" (Gemini terminology)
- Tests tool conversion to function_declarations format
- Characterizes multi-system-message behavior (last wins)
Both test files follow blackbox/integration testing principles:
- Test observable behavior through stable surfaces
- Do not assert internal implementation details
- Include documentation of what is/is not asserted
New test files:
- crates/g3-cli/tests/cli_integration_test.rs (14 tests)
Blackbox CLI tests: help/version flags, argument validation,
conflicting modes, flock mode requirements
- crates/g3-core/tests/tool_execution_test.rs (20 tests)
Tool call structure tests and unified diff application:
read_file, write_file, str_replace, shell, background_process,
todo, final_output, code_search, take_screenshot
- crates/g3-providers/tests/message_serialization_test.rs (20 tests)
Round-trip serialization tests for Message, MessageRole,
CacheControl, and Tool types. Covers Unicode, special chars,
and edge cases.
All tests follow blackbox/integration-first principles with
documentation of what they protect and intentionally do not assert.
Writes the current context window to logs/current_context_window (uses a symlink to a session ID).
This PR was unfortunately generated by a different LLM and did a ton of superficial reformating, it's actually a fairly small and benign change, but I don't want to roll back everything. Hope that's ok.
