From 9db841fc625563db18c3918ce9ad06e136cf1523 Mon Sep 17 00:00:00 2001 From: Hunter Bown Date: Tue, 28 Apr 2026 00:03:18 -0500 Subject: [PATCH] test(tui): #69 integration tests for mock LLM client + record fixtures MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Adds `integration_mock_llm.rs` covering the LlmClient trait surface: - streaming turn loop (text deltas + finish reason) - reasoning-content replay across tool-call rounds (V4 §5.1.1, the HTTP 400 path that broke v0.4.9-v0.5.1) - tool-call round-trip with chunked input JSON - multiple tool calls in one turn preserve event ordering - compaction-style non-streaming `create_message` - sub-agent style independent parent/child mocks - capacity-gate observation of a captured request Four full-engine tests are `#[ignore]`-marked as BLOCKED on the engine refactor from concrete `Option` to `Arc`. Once that wiring lands the ignored tests light up with no mock changes. Adds: - `tests/support/llm_client.rs` mirrors the trait so the mock can be brought into the integration test via `#[path]` without dragging in the rest of the binary's module tree - `tests/fixtures/.gitkeep` so the `eval --record` output directory rides the repo - `tests/README.md` documents both the trait-level mocking strategy and the `--record` fixture flow - `record_flag_writes_one_jsonl_line_per_step` in `eval_harness.rs` exercises the new `--record` flag end-to-end Co-Authored-By: Claude Opus 4.7 (1M context) --- crates/tui/tests/README.md | 56 +++ crates/tui/tests/eval_harness.rs | 42 ++ crates/tui/tests/fixtures/.gitkeep | 0 crates/tui/tests/integration_mock_llm.rs | 575 +++++++++++++++++++++++ crates/tui/tests/support/llm_client.rs | 33 ++ 5 files changed, 706 insertions(+) create mode 100644 crates/tui/tests/README.md create mode 100644 crates/tui/tests/fixtures/.gitkeep create mode 100644 crates/tui/tests/integration_mock_llm.rs create mode 100644 crates/tui/tests/support/llm_client.rs diff --git a/crates/tui/tests/README.md b/crates/tui/tests/README.md new file mode 100644 index 00000000..2715dafb --- /dev/null +++ b/crates/tui/tests/README.md @@ -0,0 +1,56 @@ +# `crates/tui/tests/` + +Integration tests for the TUI binary.

Tests mock at the **trait boundary** — never +at the `reqwest` HTTP layer — because the trait is the durable abstraction the +runtime is meant to depend on. + +Coverage today exercises the trait surface end-to-end: + +- streaming turn loop +- reasoning-content replay across tool-call rounds (V4 §5.1.1, the bug that + broke v0.4.9-v0.5.1) +- tool-call round-trip with chunked input JSON +- multi-tool-call ordering inside a single turn +- compaction-style non-streaming `create_message` +- sub-agent style independent parent/child mocks +- capacity-gate observation of a captured request before stream drain + +Four full-engine tests (`engine_full_*`) are `#[ignore]`-marked.

See the comment block at the bottom of +`integration_mock_llm.rs` for the exact refactor surface. + +## `--record` mode for `deepseek eval` + +The offline `deepseek eval` harness now accepts `--record `.

Test-only mirror of the production `llm_client` module surface. +//! +//! The integration test under `tests/integration_mock_llm.rs` includes this +//! file as `mod llm_client` and `mock.rs` as the nested submodule. Doing it +//! this way means `mock.rs`'s `super::{LlmClient, StreamEventBox}` paths +//! resolve cleanly — they refer to the trait + alias declared right here. +//! +//! The trait shape MUST stay 1:1 with the real one in +//! `crates/tui/src/llm_client/mod.rs`. If the production trait grows a method, +//! mirror it here so `mock.rs` (the same source file shipped in the binary) +//! still satisfies it. + +use anyhow::Result; +use std::pin::Pin; + +use crate::models::{MessageRequest, MessageResponse, StreamEvent}; + +pub type StreamEventBox = + Pin> + Send + 'static>>; + +#[allow(async_fn_in_trait, dead_code)] +pub trait LlmClient: Send + Sync { + fn provider_name(&self) -> &'static str; + fn model(&self) -> &str; + async fn create_message(&self, request: MessageRequest) -> Result; + async fn create_message_stream(&self, request: MessageRequest) -> Result; + async fn health_check(&self) -> Result { + Ok(true) + } +} + +#[path = "../../src/llm_client/mock.rs"] +pub mod mock;
