getAvailableRoutes() to query swapper pairs Implemented getAvailableRoutes() method in RouteGraphService that queries multiple swappers in parallel to discover available trading pairs: - Added HttpService dependency for API calls - Implemented swapper-specific query methods: - getThorchainRoutes(): Queries Midgard /v2/pools API - getMayachainRoutes(): Queries Midgard /v2/pools API - getChainflipRoutes(): Queries Chainflip assets API - getCowSwapRoutes(): Common EVM token pairs - getZrxRoutes(): Common EVM token pairs across chains - getRelayRoutes(): Cross-chain bridge pairs - getPortalsRoutes(): EVM aggregator pairs - getJupiterRoutes(): Solana DEX pairs - Added asset ID conversion helpers: - thorchainAssetToAssetId/ChainId: Converts Thorchain pool notation to CAIP - mayachainAssetToAssetId/ChainId: Converts Mayachain pool notation to CAIP - chainflipAssetToAssetId/ChainId: Converts Chainflip assets to CAIP - Uses Promise.allSettled for fault-tolerant parallel queries - Follows patterns from swap-verification.service.ts for HTTP calls - Comprehensive logging for debugging route discovery Co-Authored-By: Claude Opus 4.5 ---

Initialization tests: Service definition, quote config initialization 2. getMultiStepQuote tests: Valid paths, no path found, constraints passing, error handling, alternatives 3. getQuoteForStep tests: All supported swappers (Thorchain, Mayachain, Chainflip, CowSwap, 0x, Relay, Portals, Jupiter), unsupported swapper errors, HTTP error handling 4. aggregateMultiStepQuote tests: Single-hop/multi-hop paths, quote chaining, total fees/slippage/time calculation, caching, invalid inputs 5. Price impact tests: Calculation, warning/flag thresholds 6. Quote expiry tests: Expired/valid/edge cases 7. Asset precision handling: ETH (18), USDC (6), BTC (8) decimals 8. Edge cases: Large/small amounts, concurrent requests, empty mappings 9. Swapper-specific asset conversions: ERC20, native, SPL tokens 10. Estimated time calculations: Cross-chain vs same-chain Co-Authored-By: Claude Opus 4.5 --- .../routing/quote-aggregator.service.spec.ts | 1325 +++++++++++++++++ 1 file changed, 1325 insertions(+) create mode 100644 apps/swap-service/src/routing/quote-aggregator.service.spec.ts diff --git a/apps/swap-service/src/routing/quote-aggregator.service.spec.ts b/apps/swap-service/src/routing/quote-aggregator.service.spec.ts new file mode 100644 index 0000000..9a3509c --- /dev/null +++ b/apps/swap-service/src/routing/quote-aggregator.service.spec.ts @@ -0,0 +1,1325 @@ +import { Test, TestingModule } from '@nestjs/testing';

Note: Actual test execution requires yarn 4 with corepack in CI/CD.
