Walkthrough

The validation logic in the trade form service was updated to introduce a new check for missing input amounts when handling quote errors. Now, if the input amount is not set and a quote error occurs, a more specific validation result is returned instead of a generic error.

Changes

File(s) Change Summary
apps/cowswap-frontend/src/modules/tradeFormValidation/services/validateTradeForm.ts Added a conditional to return InputAmountNotSet if the input amount is missing during quote error handling.

Poem

A bunny hopped through fields of form,
Where quotes and errors swirl and swarm.
Now if you skip the input sum,
A clearer message soon will come.
No more generic error fright,
The path ahead is clear and bright! 🐇✨

51-54: Consider removing the later duplicate InputAmountNotSet check to cut cyclomatic complexity

The same condition is evaluated again at lines 78-80.
With the new early-return in place, the second check is now unreachable whenever tradeQuote.error is truthy, but we still evaluate it for the other branch. You can:

-  if (inputAmountIsNotSet) {
-    return TradeFormValidation.InputAmountNotSet
-  }

Move this block to the very top of the function (just after the online check) and delete both current occurrences.
This trims one nested branch, reduces duplication, and simplifies mental tracing.


119-132: Duplicate SellNativeToken validation blocks – can be collapsed into one

isNativeIn is checked twice (lines 119-122 and again 130-132) with identical return values. Consolidating them avoids dead code paths and shaves two comparisons per call.

50-56: Early-return for InputAmountNotSet is a welcome improvement, but please add a regression test

The new guard gives the “amount not set” validation higher priority over a generic quote error, which is exactly what the bug report asked for.
Please add/extend unit tests that drive tradeQuote.error = true while inputAmountIsNotSet = true to assert that the function now returns TradeFormValidation.InputAmountNotSet.
