- useWeb3Status.test.ts: 8 tests covering disconnected/connected state, isWalletSynced, switchingChain, disconnect, switchChain, appChainId - useWeb3StatusConnected.test.ts: 2 tests (co-located in same file) covering throw-on-disconnect and pass-through when connected - useErc20Balance.test.ts: 5 tests covering missing address/token, native token skip, successful balance fetch, and error handling - useTokenLists.test.ts: 4 tests covering return shape, deduplication, native token injection, and schema validation filtering
- Add beforeEach mock clearing in useWeb3Status to prevent shared mock call history leaking between tests - Switch mockReturnValue to mockReturnValueOnce for the connected test in useWeb3StatusConnected (hook calls useWeb3Status twice internally) - Add beforeEach mockReadContract.mockClear() in useErc20Balance to prevent cross-test false negatives on not.toHaveBeenCalled assertions
