Bardo Tools – Testing and Evaluation [SPEC]

Version: 4.0.0 Last Updated: 2026-03-14

Crate: bardo-tools | Prerequisites: 01-architecture.md

Four-layer testing framework: GolemSessionShim, unit tests, property-based tests, eval tests, and red-team tests.

Reader orientation: This document specifies the four-layer testing and evaluation framework for the bardo-tools crate, part of Bardo’s DeFi tool library. It covers unit tests, property-based tests, LLM eval tests, and red-team adversarial tests. The key concept is the Capability<T> token, a compile-time safety mechanism that prevents write tool reuse via Rust move semantics. Familiarity with 01-architecture.md is assumed. See prd2/shared/glossary.md for full term definitions.

Testing philosophy

Every tool is tested at four layers, each catching a different class of defect. The layers are additive – Layer 2 assumes Layer 1 passes, Layer 3 assumes Layer 2 passes.

Layer 4: Red-Team Tests (adversarial attacks, OWASP Agentic Top 10)
Layer 3: Evaluation Tests (LLM tool selection accuracy via eval harness)
Layer 2b: Property-Based Tests (proptest, invariant verification)
Layer 2: Unit Tests (business logic verification)
Layer 1: GolemSessionShim (interactive debugging, manual validation)

Layer 1: GolemSessionShim

Interactive debugging tool for manual tool validation during development.

cargo run --bin bardo-inspect
# Opens GolemSessionShim at http://localhost:6274

What it tests:

• Tool registration (tool appears in tool list)
• Parameter schema validation (invalid params rejected)
• Response format (valid ToolResult envelope)
• Error handling (structured error codes, not stack traces)
• Description quality (LLM-friendly descriptions)

Use during development: Before writing unit tests, manually verify the tool works end-to-end via the shim. This catches registration and schema issues early.

Layer 2: Unit tests

Automated tests using in-process tool invocation. Each tool has its own test module or file in crates/tools/tests/.

Test categories

Tool registration tests

Verify every tool is registered with correct metadata:

#![allow(unused)]
fn main() {
#[test]
fn get_pool_info_registered_with_correct_annotations() {
    let tool = ALL_TOOL_DEFS
        .iter()
        .find(|t| t.name == "uniswap_get_pool_info")
        .expect("tool not found");
    assert_eq!(tool.category, Category::Data);
    assert!(tool.description.len() > 50);
    assert!(tool.description.len() < 500);
}
}

Schema validation tests

Verify parameter schemas reject invalid inputs and accept valid inputs:

#![allow(unused)]
fn main() {
#[tokio::test]
async fn execute_swap_rejects_negative_amounts() {
    let params = serde_json::json!({
        "token_in": "USDC",
        "token_out": "WETH",
        "amount": "-500",
        "chain": "ethereum",
    });
    let result = EXECUTE_SWAP.handler.call(params, &test_context()).await;
    assert!(result.is_error);
    let err: ErrorPayload = serde_json::from_value(result.data).unwrap();
    assert_eq!(err.code, "VALIDATION_INVALID_AMOUNT");
}
}

Error pattern tests

Verify all error responses follow the structured error format:

#![allow(unused)]
fn main() {
#[tokio::test]
async fn errors_include_code_message_and_suggestion() {
    let params = serde_json::json!({
        "token": "NONEXISTENT",
        "chain": "ethereum",
    });
    let result = GET_TOKEN_PRICE.handler.call(params, &test_context()).await;
    let err: ErrorPayload = serde_json::from_value(result.data).unwrap();
    assert!(!err.code.is_empty());
    assert!(!err.message.is_empty());
    assert!(err.suggestion.is_some());
    assert!(err.retryable.is_some());
}
}

Safety layer tests

Verify safety middleware correctly blocks unsafe operations:

#![allow(unused)]
fn main() {
#[tokio::test]
async fn execute_swap_blocks_tokens_not_on_allowlist() {
    let params = serde_json::json!({
        "token_in": "0xSCAM_TOKEN",
        "token_out": "WETH",
        "amount": "100",
        "chain": "ethereum",
    });
    let result = EXECUTE_SWAP.handler.call(params, &test_context()).await;
    assert!(result.is_error);
    let err: ErrorPayload = serde_json::from_value(result.data).unwrap();
    assert_eq!(err.code, "SAFETY_TOKEN_NOT_ALLOWED");
}

#[tokio::test]
async fn execute_swap_blocks_amounts_exceeding_capability_limit() {
    let params = serde_json::json!({
        "token_in": "USDC",
        "token_out": "WETH",
        "amount": "999999",
        "chain": "ethereum",
    });
    let result = EXECUTE_SWAP.handler.call(params, &strict_safety_context()).await;
    assert!(result.is_error);
    let err: ErrorPayload = serde_json::from_value(result.data).unwrap();
    assert_eq!(err.code, "SAFETY_SPENDING_LIMIT_EXCEEDED");
}
}

Capability token tests

Verify write tools cannot execute without a valid capability token:

#![allow(unused)]
fn main() {
#[tokio::test]
async fn write_tool_rejects_missing_capability() {
    let params = serde_json::json!({
        "token_in": "USDC",
        "token_out": "WETH",
        "amount": "100",
        "chain": "ethereum",
    });
    // Calling write handler without a Capability<T> is a compile error,
    // but the adapter layer must verify capability presence at runtime.
    let result = call_without_capability("uniswap_execute_swap", params).await;
    assert!(result.is_error);
    let err: ErrorPayload = serde_json::from_value(result.data).unwrap();
    assert_eq!(err.code, "CAP_NOT_MINTED");
}

#[tokio::test]
async fn expired_capability_rejected() {
    let cap = mint_test_capability(
        10000.0,
        0, // already expired
    );
    let result = call_with_capability("uniswap_execute_swap", params(), cap).await;
    assert!(result.is_error);
    let err: ErrorPayload = serde_json::from_value(result.data).unwrap();
    assert_eq!(err.code, "CAP_EXPIRED");
}
}

Test infrastructure

• Test runner: cargo test (standard Rust test harness)
• Mocking: mockall for trait mocking (Signer, Provider, SubgraphClient)
• HTTP mocking: wiremock for simulating RPC, Trading API, and subgraph responses
• Fixtures: Pre-built response fixtures in crates/test-utils/
• Context: test_context() provides mock Alloy providers for testing

Layer 2b: Property-based tests

Using proptest for invariant verification. Property-based tests generate random inputs and verify invariants hold for all of them.

Example properties

#![allow(unused)]
fn main() {
use proptest::prelude::*;

proptest! {
    #[test]
    fn quote_output_never_exceeds_input_by_10x(
        amount in 0.01f64..1_000_000.0
    ) {
        let rt = tokio::runtime::Runtime::new().unwrap();
        let result = rt.block_on(get_quote_handler(
            serde_json::json!({
                "token_in": "USDC",
                "token_out": "WETH",
                "amount": amount.to_string(),
                "chain": "ethereum",
            }),
            &mock_context(),
        ));
        if !result.is_error {
            let output: QuoteResult = serde_json::from_value(result.data).unwrap();
            prop_assert!(output.amount_out_usd < amount * 10.0);
        }
    }

    #[test]
    fn spending_limit_always_enforced(
        amount in 10_001.0f64..999_999_999.0
    ) {
        let rt = tokio::runtime::Runtime::new().unwrap();
        let result = rt.block_on(execute_swap_handler(
            serde_json::json!({
                "token_in": "USDC",
                "token_out": "WETH",
                "amount": amount.to_string(),
                "chain": "ethereum",
            }),
            &strict_safety_context(),
        ));
        prop_assert!(result.is_error);
    }
}
}

Layer 3: Evaluation tests

Test LLM tool selection accuracy. Given a natural language prompt, does the LLM select the correct tool and provide correct parameters?

The eval harness is a Rust binary (bardo-eval) that calls LLM APIs with tool schemas and measures selection accuracy.

Golem testing integration

Golems run their strategies against local testnets provisioned by bootstrap_setup_local_testnet. The testnet_time_travel tool enables fast-forwarding to test time-dependent strategies (DCA cadences, LP fee accumulation, position rebalancing triggers).

The Gauntlet (swarm simulation environment running batches of Golems against forked Base chain state) is the Dream Bardo made infrastructure – Golems test hypotheses in forked environments before risking real capital. Every Gauntlet run generates episodes stored in the Grimoire (the agent’s persistent knowledge base: episodes, insights, heuristics, warnings, causal links), ensuring that simulation learnings transfer to live operation.
