/**
|
||||
* Characterization tests for the private fee-loading paths of [SwapInteractorImpl] reached by
|
||||
* the DEX provider branch:
|
||||
*
|
||||
* - `loadFeeForDex`
|
||||
* - `getFeeDataForDexSwap` (EVM)
|
||||
* - `getFeeDataForSolanaDexSwap` (Solana)
|
||||
* - the `patchTransactionFeeForSwap` 12% gas-limit bump applied on EVM DEX
|
||||
*
|
||||
* Driven through the public [SwapInteractorImpl.findBestQuote] entry point with carefully
|
||||
* stubbed dependencies so the DEX-fee branch executes deterministically.
|
||||
*
|
||||
* [REDACTED_TASK_KEY] — these tests are intentionally pinned to the **current** behavior so that the
|
||||
* upcoming refactor (extraction into `DexSwapFeeCalculator`) is provably equivalent.

* Characterization tests for `StateBuilder.createFeeState` (private), exercised through the

|

*
|

* Pinned behavior:
|

* - `TxFeeState.Empty` → `FeeItemState.Empty`
|
||||
* - `TxFeeState.SingleFeeState` → `FeeItemState.Content` with `isClickable = false`
|
||||
* - `TxFeeState.MultipleFeeState` + `selectedFeeType = NORMAL` → uses normal fee values, isClickable = true
|
||||
* - `TxFeeState.MultipleFeeState` + `selectedFeeType = PRIORITY` → uses priority fee values, isClickable = true
|
||||
* - `hideFee = true` → always `FeeItemState.Empty` regardless of `txFee`
|
||||
* - `feeCryptoFormattedWithNative` is what populates `FeeItemState.Content.amountCrypto`,
|
||||
* NOT the plain `feeCryptoFormatted`. Same for fiat. (This pins the bridge-fee
|
||||
* "display fee with native as workaround for okx" pathway.)
|
||||
*
|
||||
* [REDACTED_TASK_KEY] — these exist to guarantee the redesign's `FeeSelectorBlockComponent` carries
|
||||
* the same display semantics across the cutover.

/**
|

* Characterization tests for fee-related notifications produced by [SwapNotificationsFactory].
|
||||
*
|
||||
* Pinned behavior:
|
||||
* - [SwapNotificationUM.Error.UnableToCoverFeeWarning]:
|
||||
* adds when `feeState = NotEnough` AND `isBalanceEnough = true` AND
|
||||
* `permissionState != PermissionLoading` AND fee currency != fromCurrency,
|
||||
* AND NOT (gasless network AND CEX provider).
|
||||
* Suppressed for CEX-on-gasless-network. Re-added unconditionally when
|
||||
* `includeFeeInAmount is BalanceNotEnough`.
|
||||
* - [NotificationUM.Warning.FeeCoverageNotification]: triggers on
|
||||
* `includeFeeInAmount is Included` AND a fee is selected AND no existential deposit.
|
||||
* - [SwapNotificationUM.Info.PermissionNeeded]: triggers on `permissionState is PermissionRequired`.
|
||||
* - [SwapNotificationUM.Error.TransactionInProgressWarning]: triggers on
|
||||
* `hasOutgoingTransaction = true` (when `permissionState is not PermissionLoading`).
|
||||
* - `hideFee = true` short-circuits `maybeAddUnableCoverFeeWarning` only.
|
||||
*
|
||||
* [REDACTED_TASK_KEY] — these guard the redesign that consolidates fee-state into `SwapFee` /
|
||||
* `FeeBucket`. Phase 5 will rewrite the factory; these tests stay green throughout.
