Summary

Removes Rust tests and assertions that only restate the implementation. These tests could not catch a real regression, and they had to change in lockstep with the code they covered:

  • Constructor, getter, and setter read-backs, such as CryptoPsbt::new, CryptoSeed::new, UrResult accessors, and verification coordinator source fields
  • Tests that repeat a match table, such as balance presentation, convert_cloud_secret, and UrResult::is_*
  • Expected values built with the same helper or formula as the code, such as fee options without totals, receive-address expiry, and PSBT CBOR bytes
  • Constant checks, derived-trait checks, and assertions that re-read the test's own fixtures
  • Tests that ran against test-only copies of production logic, such as RBF detection, and the helpers they left unused

Tests that guard persisted, wire, or FFI formats, migrations, crypto and parsing vectors, redaction, user-visible copy, and state-machine or actor behavior are unchanged.

Some existing tests could never fail. They now exercise real code, and each was checked to fail when the logic it guards is removed:

  • The coinbase prevout test used a transaction with no inputs, which is not a coinbase
  • Change-address unreserve tests ran against a test-only copy of production code
  • The TAPSIGNER backup redaction test missed the decimal Debug form of the leaked bytes
  • The receive-priority cap test used a fixture where capped and uncapped scans give the same order
  • A wallet-data test called an unused #[cfg(test)] helper

Where coverage was still needed, it now lives in the restore integration tests. One test checks that unreadable wallet data blocks the restore snapshot. Another checks that a watch-only restore stores no spendable secret.

This PR also fixes a flaky iOS test, testBackupReadUsesLocalTargetBeforeMetadata. Its one-second deadline let a slow CI simulator time out a local read, which also happened on master.

Testing

  • cargo fmt --all
  • just clippy
  • just test "" --no-fail-fast: 2,029 passed, 7 skipped
  • xcodebuild ... -only-testing:CoveTests/CloudBackupIOSSafetyHelpersTests test on an iOS 18.6 simulator: 41 passed
  • swiftformat --lint and swiftlint on the changed Swift file

cargo clippy --workspace --all-targets reports 20 errors in test code this PR does not touch, in cove-nfc, cove-device, cove-types, and xtask. just clippy does not lint test targets.

Platform Coverage

  • Tested on iOS device
  • Tested on Android device
  • Tested on iOS simulator
  • Tested on Android simulator
  • Not tested

Checklist

Summary by CodeRabbit

  • Tests
    • Added checks for restore behavior when wallet data cannot be read and to confirm that restoring a watch-only wallet does not create spendable keychain material.
    • Updated address-scanning test expectations for an already-used external address.
    • Adjusted several existing checks across backup, transaction, wallet, and import flows. No end-user behavior changes are reported.

[Low risk] Removes test code that duplicates implementation checks.

The PR appears safe to merge, though the new restore test may fail when run as root.

Findings

  1. P2 Restore test fails as root ▶

Summary

This PR removes Rust tests that repeat implementation details and updates several tests to exercise real behavior. It also adds restore-safety coverage and gives one iOS simulator test a longer timeout.

  • Restore tests now check that unreadable wallet data blocks a snapshot and watch-only restores leave secrets absent.
  • Wallet and redaction tests use cases that can distinguish the behavior they cover.
  • The iOS backup-read test allows up to 60 seconds for a local read.

Keep a regression test for the preview-size contract.

Both iOS and Android display previewTextForDescription(...) together with formattedSizeForDescription(...). The removed assertion covered only the no-description case, and no surviving test checks this relationship. The upload tests cover serialized JSON and gzip limits, not the UI preview size.

Preserve the metadata-to-origin network regression test.

WalletDiscoveryScanner::try_new uses origin.network for BDK wallet creation and node selection. The surviving test constructs DiscoveryOrigin directly, so it does not detect an incorrect WalletMetadata conversion. Keep a focused assertion for metadata.network. origin.wallet_mode has no consumer in the discovery path, so its read-back does not need separate coverage.

Keep restore-boundary coverage for each cloud secret variant.

DownloadedWalletBackup::restore converts the cloud secret before dispatch. Mnemonic and xprv values use dedicated importers. TapSigner values populate tap_signer_backup, while None preserves the normal watch-only path. The surviving restore test only checks watch-only identity tracking and duplicate skipping. It does not exercise mnemonic, xprv, or TapSigner values, or assert that watch-only conversion remains None. Add focused tests for all five conversion outcomes at this restore boundary.

Restore the default settings-row projection assertion.

CloudBackupReducerState::default projects Disabled to CloudBackupSettingsRowStatus::Disabled. This status is part of the UniFFI presentation state and is sent to Swift and Kotlin.

Restore the synchronous single-message delivery test.

send_sync(TestMessage::One) uses the raw channel and converts the message to SingleOrMany::Single. The surviving test uses deferred batching and checks only Many. It would not detect a dropped or indefinitely delayed single message, or an incorrect Single payload.

Keep one bootstrap projection regression test.

initial_state() is a UniFFI record consumed directly by the platform wallet managers. The remaining tests check only ledger and load state, so they can pass if metadata, scan status, balance presentation, balance, or unsigned transactions are projected incorrectly.

Restore the deleted mapper tests.

BalancePresentation::for_ledger_state feeds both FFI methods in wallet_manager.rs. The surviving wallet-manager tests assert only ledger and load states. They do not assert the returned opacity values. A branch regression could therefore return normal presentation for an incomplete ledger, or provisional presentation for a complete ledger, without failing a test.

Add an actor-level progressive-scan state test.

The removed test only checked the constructed FullScanResponse. It did not call Wallet::apply_update or verify the next scan state. Wallet::apply_update uses last_active_indices to reveal scripts. The next scan reads those revealed indices and uses them to avoid counting already-revealed unused scripts toward the stop gap. A dropped or changed index can therefore stop a later scan too early, while the surviving producer tests still pass.

Add one focused test that applies a ScanUpdate with an active index and asserts both the wallet's last_revealed_indices and the next prepared scan's value.

WalletManager applies with_visible_window_start before persisting the cache, but receive_address_cache_round_trips persists the untransformed value. The test can therefore pass if the transformation drops wallet_id, network, derivation_index, or address_type.

Suggested fix
-        db.set_receive_address_cache(cache.clone()).unwrap();
+        let transformed = cache.with_visible_window_start(1_700_000_001);
+        db.set_receive_address_cache(transformed.clone()).unwrap();

-        assert_eq!(db.get_receive_address_cache().unwrap(), Some(cache));
+        assert_eq!(db.get_receive_address_cache().unwrap(), Some(transformed));

Restore coverage for the cached standard fee options.

without_totals populates the exported FeeSelection record. A regression that swaps a standard option can select the wrong fee rate. A regression that adds a cached total can affect balance validation and fee presentation before PSBT calculation. The surviving tests select a custom option and do not check the three standard fields.

Suggested fix
 mod tests {
+    #[test]
+    fn without_totals_preserves_standard_options_without_totals() {
+        let base = FeeRateOptions::_ffi_preview_new();
+        let actual = FeeRateOptionsWithTotalFee::without_totals(base);
+
+        assert_eq!(actual.fast, FeeRateOptionWithTotalFee::without_total(base.fast));
+        assert_eq!(actual.medium, FeeRateOptionWithTotalFee::without_total(base.medium));
+        assert_eq!(actual.slow, FeeRateOptionWithTotalFee::without_total(base.slow));
+        assert_eq!(actual.custom, None);

Add refresh_state assertions for Refreshing and Failed.

The surviving tests cover copy_policy and refresh gating, but they do not check presentation().refresh_state. A regression that always projects Idle can pass these tests while iOS and Android render the wrong lifecycle message. Add focused assertions for Refreshing and Failed propagation.

snapshot balance, and returns no unsigned transactions. Keep the existing
load-state and ledger-state assertions.

Review comments at @rust/src/manager/wallet_manager/actor.rs:
- Around line 2460-2465: The current actor tests do not verify progressive scan

Included review availability: This review used your included allowance. Your plan provides up to 2 included reviews per hour; 1 remain after this review.

Drop tests and assertions that only read back constructor fields,
mirror match tables, re-read their own fixtures, or rebuild expected
values with the same helper the code uses. They could not catch a
real regression and had to change in lockstep with the code.

Also drop tests that ran against test-only copies of production logic,
the test-only helpers and re-exports they left unused, and the
serde_json dev-dependency in cove-ur.
- Give the coinbase prevout test a real coinbase input
- Run change-address unreserve tests against the production function
- Check TAPSIGNER backup redaction in the decimal Debug form too
- Separate the capped receive-priority prefix from the normal scan
- Cover unreadable wallet data and watch-only secrets through the
  restore integration tests

Each updated test was checked to fail when the guarded logic is removed.
The fixture's one second deadline let a slow CI simulator time out the
direct local read, which then fell back to metadata the test never
starts. Use the long deadline the sibling read tests already use.
Rust 1.99 rejects eyre's bail! in match arm expression position, so
return the error value directly. Update async-trait to 0.1.92, which
stops generating code that trips the new double_must_use lint.
