test(backend-e2e): stop init-panic cascade, fix 5 stale assertions, fix TC-MN-021 - #975
Conversation
README claimed the persistent workdir is git-rev-keyed (/tmp/dash-evo-e2e-testnet-<git-rev>) and listed only 6 test modules. harness.rs actually uses a fixed base dir name with numbered fallback slots (pick_available_workdir), no git-rev component at all, and main.rs registers 20 modules. Corrected both, and pointed at main.rs as the authoritative module list to keep this table honest going forward. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>
…rkdir `AppContext::new` ends in `SpvProvider::bind_app_context`, which stores a strong `Arc<AppContext>` in a field of that same `AppContext`. The cycle means no `AppContext` is ever dropped, so the `Arc<DetKv>` it owns keeps `det-app.sqlite` registered in the upstream `SqlitePersister` process-wide open-path registry for the life of the process. `OnceCell` does not cache a panicked init, so the next test retries. Until now the retry reopened the same workdir and died with `AlreadyOpen`, burying the first attempt's real failure: a run with an invalid `E2E_WALLET_MNEMONIC` reported the mnemonic error once and `AlreadyOpen` 55 times. - Read and parse `E2E_WALLET_MNEMONIC` before any store is opened, so the most common init failure cannot leave a workdir slot poisoned. - `open_available_workdir` (was `pick_available_workdir`) also opens the app k/v and the secret vault, treating a slot still held open in-process as taken — the same fallback already used for a slot locked by another process. - Cap init attempts at 3 and point at the first failure instead of burning every workdir slot and ending on a misleading "all slots locked". Serial execution stays required, but for unrelated reasons (one shared framework wallet UTXO set, shared fixtures, the cleanup sweep); both constraints are now documented on `CTX`.

Five assertions still expected `BackendTaskSuccessResult` variants the tasks
under test can no longer produce, so each failed on a correct result.
- TC-004 / TC-005 / TC-012 / TC-018 expected `Message` from
`CreateRegistrationAssetLock` and `CreateTopUpAssetLock`. Both return only
`AssetLockBroadcast { txid }`, which the UI consumes as the broadcast
transaction id. A shared `expect_asset_lock_broadcast` helper now asserts
the variant and that the txid is a 64-character hex id.
- TC-028 handled `LoadedIdentity`, `RegisteredIdentity` and `Message` from
`SearchIdentityFromWallet`, none of which it can return; its only success
path is `IdentitiesLoaded { count: 1 }`, as sibling TC-029 already asserts.
TC-018 now runs past this assertion into the funding gap tracked in #799 and
fails there on its confirmation timeout instead.

A masternode/evonode load takes a ProTxHash, so a lookup that resolves to no node reports `MasternodeNotFound` rather than the generic `IdentityNotFound` whose "ID or name" copy is wrong for that form (`load_identity.rs`, guarded by the `masternode_not_found_message_is_node_specific` unit test). TC-MN-021 loads with `IdentityType::Evonode` and predates that variant, so it failed on the correct error. Assert `MasternodeNotFound` and that it echoes the ProTxHash that was looked up, which the generic variant cannot carry. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
📝 WalkthroughWalkthroughThe backend E2E harness now uses deterministic persistent workdir slots, opens stores during slot selection, and limits initialization retries. Task tests use shared asset-lock broadcast validation. Identity tests assert specific expected results. Documentation reflects the updated workdir and module registry. ChangesBackend E2E framework updates
Priority: ⬇️ Low — Defer this test-only backend E2E change because it is limited to initialization safeguards and stale assertion corrections. Estimated code review effort: 3 (Moderate) | ~25 minutes Merge Risk: 🟡 Moderate · up to The backend E2E test target will not compile until the assertion borrows the result, so this should be fixed before merge.

🌐 Web query:
github dashpay dash-evo-tool tests/backend-e2e/identity_tasks.rs BackendTaskSuccessResult
💡 Result:
In the dash-evo-tool repository, BackendTaskSuccessResult is a Rust enum used to represent the successful outcome of various asynchronous backend operations performed by the application [1]. It is commonly employed within the project's task execution architecture to communicate results from background workers back to the UI or application state [2][1]. For example, when a specific backend task—such as fetching masternode list data or interacting with Dash Platform identities—completes successfully, the executor returns a variant of BackendTaskSuccessResult to the application context to trigger UI updates, state changes, or routing [2][1]. The file tests/backend-e2e/identity_tasks.rs is part of the repository's backend end-to-end (E2E) testing suite [3]. These tests are designed to exercise these background tasks against a live Dash network (typically Testnet) and are explicitly marked with #[ignore] because they require network access, a funded wallet, and serial execution [3]. Consequently, the reference you are looking at involves verifying that these identity-related tasks (such as loading or registering identities) produce the expected success results [2][1]. As of September 2026, the project has undergone significant architectural changes, including a platform-wallet backend rewrite, which may have impacted how these tasks and their success results are structured or processed [4]. If you are working with this code, ensure you are referencing the active development branch (v1.0-dev), as the master branch is treated as a release-only branch and may be outdated [3].

Match result by reference before using it in the diagnostic.
BackendTaskSuccessResult derives Debug and Clone, but not Copy. matches!(result, ...) moves result, so the {result:?} diagnostic fails to compile.

Summary
Follow-up to #956's backend-e2e QA run: fixes the issues found there that are
safe to fix in test-only code, root-causes and documents the ones that aren't.
Item A — root cause of the
AlreadyOpencascade (not what it looked like)--test-threads=1was never the cause.tokio::sync::OnceCellserializescorrectly; the real trigger in the original failing run was a bad
E2E_WALLET_MNEMONIC, and every retry afterward panicked withAlreadyOpeninstead of the real cause because
AppContextis immortal in-process (astrong
Arccycle throughSpvProvider::bind_app_context— see the doccomment on
CTXinharness.rsfor the full trail), so a leakedapp_kv/secret_storehandle poisons the workdir slot for the rest of theprocess.
Fixed in
harness.rs(test-only):E2E_WALLET_MNEMONICis read/parsed before any store opens, so the mostcommon init failure can't poison a slot.
open_available_workdiralso opens the app k/v and secret vault as part ofslot selection — a slot still held open in-process is now treated as taken,
same as a slot locked by another process.
failure instead of silently burning all 10 workdir slots.
Not changed, deliberately:
SpvProvider::app_contextstaying a strongArcis the actual production root cause, but fixing it (strong →Weak)touches the SDK proof-verification/quorum path where a silent "no app
context" is funds-adjacent. Needs its own reviewed PR — tracked separately,
not in this diff.
--test-threads=1is still required, for unrelated reasons (shared frameworkwallet UTXO set,
SHARED_IDENTITYfixture, a cleanup sweep that removes everynon-framework wallet) — now documented on
CTX.Item B — 5 stale result-variant assertions
core_tasks::tc004/tc005/tc012,wallet_tasks::tc_018,identity_tasks::tc_028all asserted aBackendTaskSuccessResultvariant thetask under test cannot construct anymore (
Messagewhere the backend hasreturned
AssetLockBroadcast{txid}for a while;identity_tasks::tc_028never handled
IdentitiesLoaded{count}). Verified againstsrc/, not justthe QA log. Fixed the assertions; did not touch backend behavior.
Heads-up:
tc_018now runs on into the documentedTODO(#799)funding gapand fails there on its 360s confirmation timeout instead of failing in 1s on
the wrong assertion — correct but slower.
Item C
identity_masternode_withdraw::test_mn021) — stale test, fixed.MasternodeNotFoundis a deliberate, unit-tested variant(
src/backend_task/error.rs) for non-Useridentity types; the testpredates it. Now asserts the variant and that it echoes the resolved
ProTxHash.
shielded_tasks::tc_074_shielded_lifecycle) — investigated, NOTfixed. Attempted a bounded-poll fix for the balance-read race the original
QA run observed, but two live verification runs against testnet both failed
earlier, at the shield broadcast itself
(
TransactionConfirmationUnknown/TransactionBroadcastUnconfirmed),reproducibly. That's a different, bigger problem than what the fix
addressed, so it was reverted rather than shipped unverified.
tc_079(shield from an existing balance, no asset lock) passes — the asset-lock
shield path is the suspect. Recommend a follow-up there, not on this test.
wallet_tasks::tc_014_wallet_platform_lifecycle) — investigated,not a stale test.
step_withdrawalready polls and confirms the funds arepresent, yet Platform's ST processor rejects the same address as
under-funded — a real sync-proof vs ST-processor disagreement (already
TODO'd in
wallet_tasks.rs). No test-side fix exists that isn't apapered-over retry; leaving as-is.
