feat(ENG-5578): add integration tests with recorded market replay by tvinagre · Pull Request #127 · propeller-heads/fynd

tvinagre · 2026-03-23T16:48:15Z

Summary

Add record-market CLI tool that captures Tycho protocol stream updates and generates golden quote outputs by replaying through the full Fynd pipeline
Add integration test suite (fynd-core --test integration) that replays recorded fixtures and verifies solution availability, quality baselines, derived data, and timing
Worker pools and algorithm config loaded from worker_pools.toml to match production behavior
Golden file stores exact derived data metrics (spot prices, pool depths, token prices counts) for deterministic replay assertions
Shared golden types (GoldenFile, TestScenario, etc.) in fynd_core::recording::golden
parse_chain moved to fynd_core::types::constants for reuse across crates
Gas price captured from RPC as raw wei string (no lossy float conversion)
VM-backed protocol states (UniswapV4) filtered during recording serialization
Git LFS configured for compressed fixture files

Test plan

cargo +nightly fmt -- --check passes
cargo +nightly clippy --locked --all --all-features --all-targets -- -D warnings passes
cargo nextest run --workspace --locked --all-targets --all-features --bin fynd — 416 passed, 0 failed
All 8 integration tests pass (41/44 scenarios successful, 3 BNB pairs expected NoRouteFound)
CI runs on GitHub Actions

Cooool! And then if this fails? Can we make it alert us on slack? I'm scared it might silently fail and never be noticed/fixed.

Yes - good point. Will do that as the next step!

What is the motivation to run this periodically? 🤔 To make sure that Tycho's output is not weird? If yes, then we should support this for all chains we support 😕

and this can give a lot of warnings if the price for tokens are just "normally" moving.. 😕

@dianacarvalho1 - I believe it's a misunderstanding. This would fail only if Tycho changes its output format OR it is down.
We use the recording tool to regenerate the recordings, targets and run Fynd with the recorded data. This would also error if we are having non-deterministic values (which is most likely a bug since the data is the same).

louise-poole · 2026-03-24T14:16:52Z

I think this readme is misplaced. It should be split into 2 and be in fynd-core/src/recording and fynd-core/test/integration.

I guess some of this information should also be put into the knowledge documents for LLMs?

louise-poole · 2026-03-24T14:33:04Z

-pub(crate) struct TychoFeedConfig {
+pub struct TychoFeedConfig {


Is it needed outside of the crate? I'l scared of @zizou0x shouting at us for making something pub (loooool)

🤣 - yes I launched a subagent only for that

I made this private recently, why does it have to be public to add a test?

+/// Error returned when a chain name string cannot be parsed.

Would prefer we not list the chains here as this easily becomes outdated

+/// Derived data metrics should exactly match the golden baseline.
+/// Since replay is deterministic (same recording → same derived data),
+/// any deviation indicates a real bug, not expected variance.


Really? I would say a positive deviation is allowed. What about if there's a tycho-simulation bug that we fix. Suddenly we get more successful spot prices compared to the latest golden baseline - this is a good thing but would fail the check?

Since replay is deterministic
I can rephrase this but this stands for "same recording, same code" should return the same result

this is a good thing but would fail the check?
Yeah the flow would be:

dev would have a baseline to compare and will be very transparent about the improvements (wouldn't have to benchmark or do any manual testing).

If they look good, dev will have to update the baseline - new numbers will be easily spottable on the PR review for the reviewer.

Positive deviation can also indicate a nasty bug promising us 20 BTC for 1 ETH like the curve situation no?

+        regressions.is_empty(),
+        "quality regressions (>1% degradation):\n{}",
+        regressions.join("\n")
+    );


Oh nice! So it was just the doc that was misleading... for solution quality it is a gte check with a 1% degradation allowance. Cool cool.

louise-poole · 2026-03-24T14:58:02Z

Maybe all these integration test stuff should be feature gated? Or collected into its own mod or something? I feel like a lot of the integration test specific stuff leaked into fynd-core etc and it should be more contained.

Can you run the audit skill on these changes, por favor?

kayibal

Partial review for now. Mostly concerned about the newly exposed api surface from this PR. I think a lot of this API would be better suited to be placed within tycho-simulation if exposed publically.

kayibal · 2026-03-25T18:30:49Z

+    builder::FyndRPCBuilder,
    config::WorkerPoolsConfig,

Why did we move this?

why the _s is this supposed to mean seconds??

+            num_updates: updates.len(),


kind of pointless to have this attribute...unless you plean reading only the metadata.

Yeah - the goal was to be able to support reading the metadata without deserializing the whole updates array

+            num_bigint::BigUint::from(10_000_000_000u64)
+        }
+    };


Looks hacky... comment is not true?

kayibal · 2026-03-25T18:37:18Z

This whole module, I feel should not be here, instead it can live directly in the tool? If exposed as a lib, I think it should be in tycho-simulation

kayibal · 2026-03-25T18:38:43Z

I guess some of this information should also be put into the knowledge documents for LLMs?

+/// Expected output for a scenario.
+#[derive(Debug, Clone, Serialize, Deserialize)]

ExpectedOutput would be a way better name for this struct and you can probably extend this naming pattern up through to the module name.

+    let content = include_str!("../../../tools/benchmark/src/pairs.json");

+
+    let tokens: std::collections::HashMap<String, (Address, u32)> = raw["tokens"]


unhandled panics here all over the place. Since this is a public library function, that is unfortunately not acceptable. But I think we should consider moving as much as possible from here to the tool binary.

kayibal · 2026-03-25T18:44:19Z

+/// A serializable mirror of [`Update`].

+#[derive(Debug, Clone, Serialize, Deserialize)]


It would be a lot better to fix this quickly in tycho-simulation

Thanks - some questions mostly for my understanding

+/// Quality: each pair's amount_out_net_gas should be within 1% of golden baseline.
+#[tokio::test]
+async fn test_quality_within_golden_baseline() {


So it seems this is the most important test that we should be running in case of any code change? It took me a while to find this as an outsider - should we add this to some readme? It would be a lot easier to develop this way than to run every cargo test every time? Not sure where the best place to put this info is.

tamaralipows · 2026-03-26T21:09:31Z

+fn default_min_hops() -> usize {
+    1

Would it not be better to increase this for integration testing purposes? I feel a number of bugs happened thx to sequential swaps for example on consecutive vm protocols?

dianacarvalho1

Thank you @tvinagre ! I gave a quick review - there are already a lot of good suggestions (that I agree 👍🏼)!

+- **VM-backed protocols filtered**: Protocol states that depend on EVM engine
+  state (e.g., UniswapV4) cannot be serialized and are dropped during
+  recording. Pools for these protocols are registered as components but have
+  no simulation state, so they cannot compute spot prices or be used for
+  routing.


oohhh 😞 how difficult would it be to serialise the vm protocols? (I know that it isn't in scope of this PR!)

These should be top-level imports since this is not feature-gated nor test-only imports.
