in a subsequent PR I think I'll package these accum vars into their own struct.

In a subsequent PR I'll refactor crossTick to not return LiquidityNet, it just reads that from one of the args.

if err != nil {
return swapState, err
}
}
liquidityNet := nextInitializedTickInfo.LiquidityNet

// Move next tick iterator to the next tick as the tick is crossed.
nextTickIter.Next()

The function populateSwapTestFields modifies the test cases in place to ensure that certain fields are not nil. Consider adding a comment to clarify the purpose of this function and why it's necessary to modify the test cases in this manner. This will improve the readability and maintainability of the test suite.

+ // populateSwapTestFields ensures that all test cases have non-nil expected values for certain fields.
