…ting Suite Complete implementation of security testing suite for Soroban smart contracts: SECURITY TESTS: - Reentrancy attack prevention tests - Integer overflow/underflow protection - Timestamp manipulation resistance - Unauthorized access attempts - Invalid state transition attempts ECONOMIC ATTACK SIMULATION: - Front-running booking attempts - Price manipulation scenarios - Cancellation abuse prevention - Listing manipulation scenarios FUZZING TESTS: - Property fuzzing (26 unique combinations) - Booking fuzzing (26 unique combinations) - Review fuzzing (26 unique combinations) - Random valid/invalid input testing CROSS-CONTRACT INTEGRATION: - Booking + Property-listing + Review interaction - State synchronization validation - End-to-end workflow testing GAS OPTIMIZATION: - Transaction cost validation - Performance monitoring setup - Gas consumption measurement DEPLOYMENT VALIDATION: - Testnet and Mainnet compatibility - Network-specific behavior testing - CI/CD integration ready TEST RESULTS: - review-contract: 20 tests (17 passed, 3 should panic) - booking: 25 tests (22 passed, 3 should panic) - property-listing: 19 tests (16 passed, 3 should panic)
WalkthroughThis change set massively expands the security and edge case test coverage for the Booking, Property Listing, and Review Soroban smart contracts. It introduces comprehensive new test scenarios—including reentrancy, overflow/underflow, timestamp manipulation, unauthorized access, invalid state transitions, economic attacks, fuzzing, cross-contract workflows, gas optimization, and deployment validation—while updating contract registration calls and adding numerous JSON test snapshots.

73-81: Type/semantic drift between key and stored value
StorageKey::ReviewMapsuggests the value is a map, yet you persist aVec<Review>.
Either rename the enum variant (e.g.,ReviewsForUser) or actually storeReviewMap. Aligning the naming prevents future confusion.

3-4: Unusedvecmacro can be removed.After dropping
symbol_short, thevecmacro re-export is also no longer used in this file. Removing it avoids a needless import and suppresses the “unused import” compiler lint.-use soroban_sdk::{ - contract, contractimpl, contracttype, vec, Address, Env, Symbol, Vec, -}; +use soroban_sdk::{contract, contractimpl, contracttype, Address, Env, Symbol, Vec};apps/stellar-contracts/contracts/booking/test_snapshots/test/test_edge_cases.1.json (1)
22-32: Snapshot size / long-lived binary blobs
Large raw WASM hashes and deep ledger trees are checked into VCS. Consider either:
- Compressing snapshots (e.g., gzip +
*.json.gz) and decoding at test runtime, or- Generating snapshots on-the-fly inside the test harness.
It keeps the repository lightweight and avoids 💾 bloat over time.
Also applies to: 441-470

35-44: Very large fixture – evaluate maintenance strategy
This 1 200-line snapshot is great for coverage, but future contract schema changes will cause painful merge conflicts. You may want to:• split per-property fixtures, • move to programmatic builders (e.g., `TestEnv::seed_fuzz_state(&env, 26)`), • or store compressed artefacts in `./tests/fixtures/`.Also applies to: 64-112
apps/stellar-contracts/contracts/review-contract/src/lib.rs (2)
24-28: Dead code:ReputationScoresMap/ReviewMapstructs never used
Both helper structs are defined but not referenced anywhere in the contract or tests. Remove them or integrate them to avoid misleading future readers.
61-63: Redundant parentheses & trailing semicolon

38-57: Snapshot naming nit
Consider prefixing overflow/underflow fixtures with the contract ABI version, e.g.,
v1_overflow_underflow.json, enabling parallel support when the schema evolves.Also applies to: 96-113
apps/stellar-contracts/contracts/property-listing/test_snapshots/test/test_invalid_state_transition_attempts.1.json (1)
40-88: Single-scenario fixture
Only the “Available → …” baseline state is stored. If the invalid-transition tests need multiple states (e.g.,Booked,Cancelled), consider parameterised helpers instead of separate JSON files for each.apps/stellar-contracts/contracts/property-listing/test_snapshots/test/test_gas_optimization_validation.1.json (1)
40-47: Storing an empty WASM hash (e3b0…) prevents code/ledger hash coherence checks
"hash": "e3b0…"is the SHA-256 of an empty payload; the accompanyingcodefield is also empty.
That is fine for pure-storage tests, but any future test that validateshash(code)==hashor performs contract-code size metering will fail.Consider snapshotting the real compiled WASM bytes for long-term robustness.
apps/stellar-contracts/contracts/review-contract/test_snapshots/test/test_economic_attack_simulation.1.json (1)
145-149: Empty contract code again—economic-attack simulation may miss re-entrancy via WASM instrumentationSeveral economic-attack tests (e.g. front-running or price-manipulation scenarios) often rely on instrumented WASM hooks.
With an empty code payload the VM cannot exercise these paths; the test effectively becomes a pure-storage diff.If your attack simulation mocks the contract logic at a higher layer, ignore this; else embed the real compiled WASM.

1-450: Snapshot size is excessive – prune to the minimal state that the assertions actually requireAt ~450 lines this fixture alone adds ~17 KB of raw JSON. Dozens of similar files quickly bloat the repository and slow CI checkout.
Unless every datum (e.g., duplicatedcontract_codeblobs,BOOKCOUNT, per-entry TTLs) is explicitly asserted on in the test, consider:• Generating the snapshot programmatically in-test (e.g., helper that seeds only the required keys).
• Or trimming the JSON to just the K-V pairs the test reads.
• If full snapshots are indispensable, commit them gzip-compressed and inflate in the test runner.This keeps history diff-noise low and speeds future reviews.
apps/stellar-contracts/contracts/property-listing/test_snapshots/test/test_economic_attack_simulation.1.json (1)
20-90: Duplicate contract code hashes repeated across many snapshots – centralise to reduce churnIdentical empty-WASM hashes (
e3b0…b855) and surrounding metadata recur in every property-listing & booking snapshot. Consider extracting these common pieces into a helper that injects them at test runtime or stores them in a single shared fixture to avoid repeating ~30 lines per file.apps/stellar-contracts/contracts/property-listing/test_snapshots/test/test_edge_cases.1.json (1)
42-138: Edge-case fixture mixes unrelated properties – split per scenario for clarity
PROP2andPROP_SPexercise different edge cases but live in the same snapshot. Splitting into dedicated fixtures (…edge_case_prop2.json,…edge_case_sponsored.json) clarifies intent and avoids accidental coupling between tests.apps/stellar-contracts/contracts/review-contract/test_snapshots/test/test_property_fuzzing.1.json (2)
61-70: Snapshot size is excessive → generate programmatically insteadThis single fixture is ~2.8 K LOC and ~150 KB on disk.
Keeping 26 almost-identical entries bloats the repo history and slows CI checkouts.Refactor the test to build the ledger state on-the-fly inside the test harness and commit only a minimal seed snapshot, or compress the JSON (e.g.
*.json.gz) and load it at runtime.
2280-2285: Zero timestamps remove fuzzing dimensionAll 26 reviews use
timestamp = 0; timestamp-related edge cases (ordering, expiry) are therefore untested.
Randomise or parametrise the value to exercise the date logic.apps/stellar-contracts/contracts/review-contract/test_snapshots/test/test_reentrancy_attack_prevention.1.json (1)
147-150: Emptystorageincontract_instanceweakens re-entrancy coverageReal-world re-entrancy often depends on non-trivial storage mutations.
An empty storage map may not reproduce the exact call-stack depth or rent costs seen in production.Populate
storagewith at least one mutable key so state-changing paths are exercised.apps/stellar-contracts/contracts/review-contract/test_snapshots/test/test_edge_cases.1.json (1)
120-140: Inconsistent rating scale across entriesEntry 2 uses
rating = 1while the rest are5.
If the valid range is 1-5 this is fine, but if the contract treats values ≤ 0 or ≥ n differently, consider adding boundary values (0,MAX_U32) to stress-test overflow guards.apps/stellar-contracts/contracts/booking/src/test.rs (7)
488-491: Translate comments to English for consistencyThe codebase uses English, but these comments are in Spanish.

648-705: Refactor repetitive string generationThe property and user ID generation is very repetitive. Consider using a more maintainable approach:
- let property_id = String::from_str(&env, match i { - 0 => "PROP_A", - 1 => "PROP_B", - // ... 24 more cases ... - _ => "PROP_Z", - }); - let user_id = String::from_str(&env, match i { - 0 => "USER_A", - 1 => "USER_B", - // ... 24 more cases ... - _ => "USER_Z", - }); + let property_id = String::from_str(&env, &format!("PROP_{}", (b'A' + (i as u8)) as char)); + let user_id = String::from_str(&env, &format!("USER_{}", (b'A' + (i as u8)) as char));

145-147: Good use of#[cfg(test)].Turning the test module into a cfg-gated compilation unit keeps the WASM size minimal for production builds.
apps/stellar-contracts/contracts/property-listing/test_snapshots/test/test_cross_contract_interaction.1.json (1)
40-90: Snapshot uses empty WASM code – confirm intentional.The
contract_code.codefield is an empty string. If the cross-contract tests rely on executing the compiled WASM, an empty blob will make any invocation fail withContractCodeError.
If execution is mocked and only storage layout is validated, keep as-is; otherwise replace with the actual artifact hash.apps/stellar-contracts/contracts/booking/test_snapshots/test/test_integer_overflow_underflow.1.json (1)
20-45: 👍 Clear baseline for overflow/underflow tests.Initialization of
BOOKCOUNTto zero and fixed timestamp make boundary conditions deterministic. No issues spotted.apps/stellar-contracts/contracts/property-listing/test_snapshots/test/test_reentrancy_attack_prevention.1.json (1)
20-90: Ledger snapshot looks sane for reentrancy tests.Contains a single
PROP1entry markedAvailable– adequate for duplicate-creation simulations. No discrepancies detected.apps/stellar-contracts/contracts/booking/test_snapshots/test/test_timestamp_manipulation_resistance.1.json (1)
12-15: Extreme timestamp may overflow downstream tooling.The snapshot timestamp is set to
18446744073709551615(u64 max).
While Soroban-VM accepts it, host integrations that cast to signed i64 (common in JS/TS SDKs, some Rust wrappers) will overflow or clamp, breaking replay or diff tooling.Confirm that:
- All supporting libraries in CI ingest this value losslessly.
- There is an explicit assertion in the test guaranteeing the contract handles the overflow case.
If not strictly required, consider replacing with
2**63-1to stay within signed ranges.apps/stellar-contracts/contracts/property-listing/test_snapshots/test/test_gas_optimization_validation.1.json (1)
14-21: Zeroed timestamp & base reserve may invalidate time-/fee-sensitive test pathsThe ledger header fixes
timestampandbase_reserveto0.
If any gas-cost or fee-calculation branches internally read either field, the snapshot will not exercise realistic network conditions and may mask time-dependent or fee-bounded regressions.No functional bug—just confirm the contracts never branch on these two values in the gas-optimisation tests.
If they do, set them to representative non-zero constants instead.apps/stellar-contracts/contracts/review-contract/test_snapshots/test/test_integer_overflow_underflow.1.json (1)
40-45:storage: nullgives the overflow/underflow test a blank slate—verify this is intendedOverflow scenarios usually rely on an existing counter or balance that is about to wrap.
Withstorageset tonull, the contract starts from scratch; the test must write the initial near-boundary values itself.Double-check that the Rust test does so; otherwise the edge-case path may be skipped.
apps/stellar-contracts/contracts/review-contract/test_snapshots/test/test_economic_attack_simulation.1.json (1)
110-114:timestampfixed at0—attacks that compare block age will be inertThe snapshot sets the stored review record’s
"timestamp": 0.
If the contract blocks edits based on the elapsed time since creation, this constant disables that branch.Ensure the test explicitly rewrites the timestamp or that the business rules do not depend on it.
apps/stellar-contracts/contracts/review-contract/test_snapshots/test/test_invalid_state_transition_attempts.1.json (1)
1-76: Snapshot looks good—sufficient for invalid-transition negative testsNo structural or data anomalies spotted; the minimalist instance is appropriate for transition-validation tests.
apps/stellar-contracts/contracts/review-contract/test_snapshots/test/test_timestamp_manipulation_resistance.1.json (1)
12-15: No lossy timestamp casts detected in review-contract codeI ran a search for any narrowing casts of the ledger
timestamp(e.g.as i64oras i32) inapps/stellar-contracts/contracts/review-contractand found no occurrences. The JSON snapshots deserializetimestampasu64, and all internal usages preserve that type. No changes are required here.apps/stellar-contracts/contracts/review-contract/test_snapshots/test/test_unauthorized_access_attempts.1.json (1)
1-76: LGTM – lean fixture focused on contract instance/code onlyThe snapshot contains only the contract instance and code required for the unauthorized-access test – concise and purposeful.
apps/stellar-contracts/contracts/review-contract/test_snapshots/test/test_property_fuzzing.1.json (1)
78-88: Repeated"review"IDs may mask uniqueness bugsEvery map sets
"id": "review".
If the contract logic relies on review ID uniqueness, this fixture cannot catch collisions.Vary the
idfield per entry (e.g.reviewA … reviewZ) so accidental duplication is surfaced.apps/stellar-contracts/contracts/review-contract/test_snapshots/test/test_edge_cases.1.json (1)
70-79: Edge-case review has empty comment but stillrating = 5Ensure the contract validation explicitly allows / rejects empty comments; otherwise this snapshot could normalise invalid data.
apps/stellar-contracts/contracts/review-contract/test_snapshots/test/test_cross_contract_interaction.1.json (1)
149-149: Test snapshots intentionally use empty WASM hash
Verified that every JSON snapshot under apps/stellar-contracts/contracts/**/test_snapshots/ uses the SHA256 of an empty string (e3b0c44298fc1c149afbf4c8996fb92427ae41e4649b934ca495991b7852b855) and an emptycodefield. This is by design for mocking deployments in tests. No changes required.apps/stellar-contracts/contracts/booking/test_snapshots/test/test_economic_attack_simulation.1.json (1)

apps/stellar-contracts/contracts/review-contract/test_snapshots/test/test_deployment_validation_networks.1.json (1)

Fix unreachable code in economic attack simulation test
The test expects a panic at line 619, making all subsequent code unreachable. The test logic for cancellation abuse and price manipulation (lines 621-632) will never execute.
Consider splitting this into separate tests or removing the #[should_panic] attribute:
-#[should_panic(expected = "Booking overlap")]
fn test_economic_attack_simulation() {
// ... setup code ...
- // Test 1: Front-running - dos usuarios intentan reservar el mismo slot
+ // Test 1: Front-running - two users try to book the same slot
let booking_id1 = client.create_booking(&property_id, &user_id1, &start_date, &end_date, &total_price);
- // Intentar crear booking solapado (debe panicar)
- client.create_booking(&property_id, &user_id2, &start_date, &end_date, &total_price);
+
+ // Verify that overlapping booking fails

+ client.create_booking(&property_id, &user_id2, &start_date, &end_date, &total_price);

In apps/stellar-contracts/contracts/booking/src/test.rs from lines 598 to 633,
the test_economic_attack_simulation function is marked with #[should_panic]
expecting a panic at line 619, which causes all code after that line to be
unreachable and never executed. To fix this, split the test into multiple
separate tests: one that checks the panic on overlapping bookings with
#[should_panic], and other independent tests for cancellation abuse and price
manipulation without the panic attribute. This ensures all test scenarios run
and validate correctly.

the assertions checking success_count are contradictory because one asserts it
equals 26 and another asserts it is at least 26. Remove the assertion that
conflicts with the intended test logic, keeping either the exact match or the
minimum threshold assertion to avoid redundancy and contradiction.

🧩 Analysis chain
Persistent-entry TTL violates ledger minimum – tests may fail on strict validators.
min_persistent_entry_ttl is defined as 4096 (line 18) but every persistent ledger_entry is given a TTL of 4095 (e.g. lines 124, 155, 268 …).
Stellar-Core rejects a snapshot whose entry TTL is below this network minimum, so the fixture can become unusable when the core version/feature-flag enforcement changes.
Proposed fix (apply to every affected snapshot file):
- 4095
+ 4096Run the full test-suite against a node built from the latest protocol/22 commit to verify the fixture still materialises correctly.

Persistent-entry TTL below network minimum in JSON fixture
The snapshot defines "min_persistent_entry_ttl": 4096, but several persistent entries use a TTL of 4095, which Stellar-Core will reject on strict-validator settings. Update each occurrence to match the network minimum:

get_all_listings still returns an empty placeholder – implement real storage iteration.
vec![env] yields a Vec<Env> containing the environment itself, not any PropertyListing.
Callers expecting actual listings will either panic (type mismatch) or silently receive an empty list, masking bugs.
Minimal safe fallback:
- pub fn get_all_listings(env: &Env) -> Vec<PropertyListing> {
- let listings = vec![env];
- // Note: In a real implementation, you would need to implement a way to iterate over all listings
- // This is a simplified version that would need to be expanded based on your specific needs
- listings

+ // Until that is in place, returning an empty vector is safer than a
+ // malformed one.
+ Vec::<PropertyListing>::new(env)
+ }Consider persisting an index of listing IDs at creation time and looping over it to build the vector.
Failing to address this will break any of the new cross-contract integration tests that rely on retrieving listings.

In apps/stellar-contracts/contracts/property-listing/src/lib.rs around lines 137
to 142, the get_all_listings function incorrectly returns a vector containing
the environment instead of actual PropertyListing items. To fix this, implement
real storage iteration by maintaining an index of listing IDs when listings are
created, then iterate over this index to retrieve each PropertyListing from
storage and collect them into a vector to return. Replace the placeholder
vec![env] with this proper retrieval logic to ensure callers receive the correct
listings and avoid type mismatches or empty results.

Use unique review IDs instead of constant placeholder
symbol_short!("review") yields the same symbol for every review, preventing straightforward look-ups or future migrations.
- id: symbol_short!("review"), // id is not used for lookup, keep placeholder

This change keeps id meaningful with negligible gas cost.

replace the constant placeholder symbol_short!("review") used for the id field
with a unique or deterministic identifier for each review, such as a counter or
a unique hash. This ensures each review has a distinct id, enabling
straightforward look-ups and supporting future migrations without significant
gas cost.

Test name doesn't match behavior - testing duplicate prevention, not reentrancy.
Similar to the property listing test, this is checking duplicate review prevention rather than reentrancy. Consider renaming for clarity.

Simplify ID generation using arrays or string formatting.
These match statements are overly verbose and could be simplified.
Consider using a const array approach:
const BOOKING_IDS: [&str; 26] = ["bookingA", "bookingB", /* ... */, "bookingZ"];
const REVIEWER_IDS: [&str; 26] = ["reviewerA", "reviewerB", /* ... */, "reviewerZ"];
const TARGET_IDS: [&str; 26] = ["targetA", "targetB", /* ... */, "targetZ"];
let booking_id = Symbol::new(&env, BOOKING_IDS[i as usize]);

In apps/stellar-contracts/contracts/review-contract/src/test.rs around lines 311
to 338, the booking_id assignment uses a long match statement for each index.
Replace this with a const array of booking ID strings indexed by i, then create
the Symbol using the array element. This simplifies the code and improves
readability. Similarly, apply the same pattern for reviewer_did and target_did
using their respective const arrays.

Snapshot ledger meta looks unrealistic for gas–sensitive assertions
base_reserve, min_*_ttl, and especially the empty code blob are all zero / blank.
When the same snapshot is re-used to benchmark gas, the host may short-circuit several cost branches that depend on non-zero reserve and code length, so the measured figures will be artificially low.
Consider initialising these fields with realistic test-net values (e.g. base_reserve: 10, non-zero WASM length) to avoid “too good to be true” gas numbers.
Also applies to: 235-236
