From 0cd7f9e91211fb09be4cf5db1fc41ddcc9f479d4 Mon Sep 17 00:00:00 2001 From: Hui-Sang Kim <102507786+Hiksang@users.noreply.github.com> Date: Thu, 7 May 2026 02:23:41 +0900 Subject: [PATCH] test(lp): unit tests for lp positions subcommand (offline mocked) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit lp.ts is 1803 LOC — the largest still-untested CLI handler at the start of this PR stack. The full surface (add/remove/farm/claim/ discover/pipeline/compound/autopilot/positions) needs to be split across multiple PRs. This commit covers only the smallest leaf (`lp positions`) so the basic --chain / --protocol / --address routing has shape-pinning regression coverage; other subcommands will follow in their own PRs. 4 new tests in lp-positions.test.ts: - errors when --chain is missing (no protocol enumeration) Asserts the standard "--chain is required" error envelope. - returns an empty array when balanceOf returns 0n across every protocol on the chain The viem.readContract mock returns 0n for every NPM contract; every protocol's NFT enumeration short-circuits and the output is the canonical empty array. - --protocol filter narrows enumeration to a single protocol Pins that --protocol controls the loop scope. - --address parameter overrides DEFI_WALLET_ADDRESS without throwing Pins the resolveAccount priority and ensures opts.address wins. Mock strategy: - vi.mock("viem"): createPublicClient.readContract returns 0n, so every NPM balanceOf reports zero NFTs and the loop is skipped. http() is a no-op factory. - vi.mock("@hypurrquant/defi-protocols"): createMerchantMoeLB returns an adapter whose discoverRewardedPools / etc. return [], so the LB scan path doesn't reach the network either. - All other adapter constructors fall through to the real implementations because the test protocols (uniswap-v2-monad, uniswap-v3-monad) don't trigger them in the empty-positions branch. Verified: - pnpm -C ts -r build — clean. - pnpm -C ts -r lint — 3 packages, tsc --noEmit clean. - pnpm -C ts -r test — defi-core 32/32, defi-protocols 43/43, defi-cli 98/98 (+4 lp-positions tests on a baseline of 94 swap tests; the merged main after PR #18 will be 102 once both land). --- .../src/commands/lp-positions.test.ts | 216 ++++++++++++++++++ 1 file changed, 216 insertions(+) create mode 100644 ts/packages/defi-cli/src/commands/lp-positions.test.ts diff --git a/ts/packages/defi-cli/src/commands/lp-positions.test.ts b/ts/packages/defi-cli/src/commands/lp-positions.test.ts new file mode 100644 index 0000000..44a1893 --- /dev/null +++ b/ts/packages/defi-cli/src/commands/lp-positions.test.ts @@ -0,0 +1,216 @@ +// Unit tests for `defi lp positions` — covers the smallest leaf of lp.ts +// (1803 LOC, the largest still-untested handler at the start of this PR +// stack).
