From bab3550ebf5d61f2634adf8f84da7585cdb309b6 Mon Sep 17 00:00:00 2001 From: giteadmin Date: Fri, 18 Jul 2025 22:39:22 +0200 Subject: [PATCH] Add position contiguity validation and VWAP recording test improvements MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit - Enhanced LiquidityManager test infrastructure with position contiguity checking - Added tick range validation to Response struct and checkLiquidity() function - Implemented proper assertions for testRecordVolumeAndPriceUnsafe() fuzzing test - Added anchor-discovery contiguity validation for both token orderings - Improved VWAP overflow detection testing with contract state validation - Updated testing todos with completion status and priority analysis 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude --- onchain/test/LiquidityManager.t.sol | 29 +++++++ onchain/test/VWAPDoubleOverflowAnalysis.t.sol | 86 +++++++++++++------ onchain/testing_todos.md | 54 ++++++++++++ 3 files changed, 144 insertions(+), 25 deletions(-) create mode 100644 onchain/testing_todos.md diff --git a/onchain/test/LiquidityManager.t.sol b/onchain/test/LiquidityManager.t.sol index cf2cd6c..a1c8490 100644 --- a/onchain/test/LiquidityManager.t.sol +++ b/onchain/test/LiquidityManager.t.sol @@ -84,6 +84,12 @@ contract LiquidityManagerTest is UniswapTestBase { uint256 harbergFloor;
