Add every client method to the mock client, update the budget response builders to the ynab v4 plan shape, and add user + money-movements fixtures. Groundwork for comprehensive handler tests. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_016PgWfscEzb25EXrgJg1Mt5
Add unit tests for loadConfig, the YnabClient SDK wrapper (read/write paths, caching, audit logging, read-only guards), scheduled-transaction handlers, and system tools (rate-limit, audit-log, health-check). Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_016PgWfscEzb25EXrgJg1Mt5
…tools Add handler unit tests for the read/write tools across these domains, including the v4 plan-shaped budget responses and the new payee/money- movement tools. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_016PgWfscEzb25EXrgJg1Mt5
Add handler unit tests for all transaction tools (incl. bulk create/update and the per-account/category/payee listings) and category tools (incl. the new create-category, create/update category-group), asserting dollar→ milliunit conversion on writes. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_016PgWfscEzb25EXrgJg1Mt5
Add handler unit tests for the 18 previously-untested analytics tools (detect-recurring, cash-flow-forecast, preview-scheduled, transaction-search, budget-suggestions, and the rest), covering happy paths and branch cases. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_016PgWfscEzb25EXrgJg1Mt5
Coverage now ~94% lines / ~84% branches / ~97% funcs across 614 tests, so raise the vitest thresholds back to 80 on all metrics. Pin the system clock in the cash-flow-forecast test (fake timers, fixed mid-month date) to remove wall-clock flakiness at month boundaries.

WalkthroughThis PR adds a comprehensive Vitest unit test suite covering configuration loading, the YnabClient service, and nearly every tool handler (accounts, analytics, budgets, categories, months, money movements, payees, scheduled transactions, system, transactions, user). It also updates shared mock fixtures for a renamed YNAB v4 schema and raises coverage threshold minimums. ChangesTest Suite Expansion

Inline comments:
In `@tests/unit/services/ynab-client.test.ts`:
- Around line 466-894: The write-method tests in ynab-client.test.ts repeat the
same resolve/reject, invoke, and audit-log assertions across many describe
blocks. Extract that shared success/failure pattern into a small parameterized
helper or table-driven test utility, then reuse it for methods like
createAccount, updateMonthCategory, createTransaction, and the other write
operations while keeping the same coverage and assertions.
In `@tests/unit/tools/accounts/list-accounts.test.ts`:
- Around line 1-103: Add negative-path coverage to handleListAccounts in
list-accounts.test.ts by testing invalid input and a rejected client.getAccounts
call. Use the handleListAccounts function and MockClient to verify zod/input
validation failures and thrown client errors are handled without leaking
internal details, and assert the returned error shape/message is safe and
user-facing. Mirror this pattern in the other account tool suites so the
success-only coverage is extended to error handling as required.
- Around line 74-83: The test named omits liability_credits when none exist is
not actually exercising that branch because it still uses mockAllAccounts and
only checks that parsed.summary exists. Update this test to use an accounts
fixture that contains no liability/overpayment credit entries, then assert
directly on the parsed output from handleListAccounts that liability_credits is
absent (or undefined) in the summary. Keep the test focused on the omission path
by using the existing createAccountsResponse and mockClient.getAccounts setup
with a no-credit account list.
In `@tests/unit/tools/analytics/budget-suggestions.test.ts`:
- Around line 17-32: The monthWith helper is duplicated in another analytics
test, so factor it into a shared builder under tests/unit/tools/fixtures and
reuse it from budget-suggestions.test.ts and the matching test. Keep the
existing monthWith behavior intact by extracting the common category/month
construction logic into a single helper with the same inputs and hidden default
handling.
In `@tests/unit/tools/analytics/cash-flow-forecast.test.ts`:
- Around line 1-191: The analytics test suites are missing coverage for
error-handling and information-leakage behavior, so add negative tests around
handler entry points like handleCashFlowForecast (and the similar analytics
handlers in this cohort) that cover invalid input and rejected client calls.
Assert the returned/raised error shape is sanitized and does not expose internal
details such as file paths, raw IDs, or stack traces, while keeping the existing
happy-path assertions intact.
In `@tests/unit/tools/analytics/transaction-search.test.ts`:
- Around line 61-75: The amount-range test in handleTransactionSearch is using a
tautological assertion that never inspects the returned transactions, so it does
not verify filtering behavior. Replace the dead every(...) check with assertions
against the actual transaction fields returned by handleTransactionSearch (the
mapped objects with amount, date, payee, category, memo, account, cleared) and
explicitly confirm every match falls within the requested absolute range in
addition to excluding out-of-range values like the $105 transaction.
In `@tests/unit/tools/budgets/get-budget-settings.test.ts`:
- Around line 21-64: The get-budget-settings test suite only covers successful
and null-format responses, so add an error-path test for handleGetBudgetSettings
that makes mockClient.getBudgetSettingsById reject with a simulated API/network
failure. Verify the handler’s error handling does not leak raw error details in
its returned JSON or thrown message, and keep the test alongside the existing
handleGetBudgetSettings and mockClient expectations.
In `@tests/unit/tools/budgets/get-budget.test.ts`:
- Around line 21-78: The handleGetBudget test suite is missing coverage for the
getBudgetById failure path, so add a test that makes mockClient.getBudgetById
reject and verifies the handler’s error behavior and returned message content.
Use handleGetBudget and mockClient to assert the rejection path is exercised and
that the error response does not leak sensitive/internal details, matching the
existing patterns in this suite.
In `@tests/unit/tools/months/get-month.test.ts`:
- Around line 1-80: Add error-path coverage for handleGetMonth by simulating
rejected getBudgetMonth and getCategories calls (they are awaited together via
Promise.all) and asserting the handler’s response does not expose internal
details like stack traces, file paths, or raw API payloads. Locate the tests
around handleGetMonth in get-month.test.ts and mirror the same leakage checks in
list-money-movements.test.ts and list-months.test.ts so all list/month handlers
verify sanitized error output.
In `@tests/unit/tools/payees/create-payee.test.ts`:
- Around line 10-43: Add an error-path test for handleCreatePayee in
create-payee.test.ts by mocking mockClient.createPayee with a rejection and
asserting the handler fails without exposing raw internal error details. Extend
the existing describe('handleCreatePayee') suite to cover the rejected
createPayee case, using handleCreatePayee and mockClient.createPayee, and verify
the thrown/rejected message does not contain API bodies, stack traces, or
internal paths while still surfacing a generic failure.
In `@tests/unit/tools/system/audit-log.test.ts`:
- Around line 101-108: The limit test in handleAuditLog only checks the returned
count and misses the ordering guarantee from getFiltered. Update the audit log
test case in audit-log.test.ts for handleAuditLog so it also asserts the single
entry returned when limit is 1 is the most recent action (the delete entry),
using the existing seedEntries setup and parsed result structure.
In `@tests/unit/tools/system/rate-limit-status.test.ts`:
- Around line 28-46: Add boundary coverage for the rate-limit threshold logic in
handleRateLimitStatus by extending the tests in rate-limit-status.test.ts to
exercise the exact flip points at 50% and 80% usage. Use
mockClient.getRateLimitStatus with boundary percentUsed values so you verify the
expected status/message behavior changes precisely at those edges, alongside the
existing warning/critical cases.
In `@tests/unit/tools/transactions/import-transactions.test.ts`:
- Around line 10-61: Add an error-path unit test in handleImportTransactions to
cover failure handling, not just the success cases. Use the existing
handleImportTransactions and createMockClient setup to make
client.importTransactions reject or resolve with invalid input, then assert the
thrown/returned error is sanitized and does not leak internal details from the
client or schema parsing. Keep the existing assertions for importTransactions
and resolveBudgetId, and extend the test file’s coverage to validate the error
message behavior under failure conditions.
In `@tests/unit/tools/transactions/list-account-transactions.test.ts`:
- Around line 17-90: Add error-path coverage for handleListAccountTransactions
by testing the failure behavior of getAccountTransactions and schema validation.
Extend the existing describe block to include a case where
mockClient.getAccountTransactions rejects and assert the handler returns the
expected safe error response without leaking internals, and another case that
passes invalid input so the schema rejection path is exercised. Keep the
assertions focused on the handleListAccountTransactions function and MockClient
behavior.
In `@tests/unit/tools/transactions/list-category-transactions.test.ts`:
- Around line 16-99: Add missing error-path coverage in
handleListCategoryTransactions: extend the tests around createMockClient and
mockClient.getCategoryTransactions to verify the tool fails cleanly when the
client rejects and when response/schema validation fails. Reuse the existing
handleListCategoryTransactions test setup to assert the error behavior for these
two paths, matching the patterns used in the other transaction tool tests.
In `@tests/unit/tools/transactions/list-payee-transactions.test.ts`:
- Around line 18-102: Add negative test coverage for handleListPayeeTransactions
in list-payee-transactions.test.ts by exercising the failure paths around
mockClient.getPayeeTransactions and request validation. Create a test that makes
getPayeeTransactions reject and assert the handler surfaces the expected error
behavior, and add a test that passes invalid input so schema validation fails
before the client call. Use the existing handleListPayeeTransactions and
createMockClient setup to keep the new cases aligned with the current test
style.
In `@tests/unit/tools/transactions/list-transactions.test.ts`:
- Around line 16-110: Add error-path coverage to handleListTransactions in
list-transactions.test.ts by exercising both a rejected
mockClient.getTransactions call and a response that fails schema validation. Use
the existing handleListTransactions and mockClient.getTransactions setup to
assert the function returns the expected failure behavior for each case, and
keep the tests aligned with the current JSON output shape and error handling.
In `@tests/unit/tools/transactions/update-transaction.test.ts`:
- Around line 95-112: The validation tests in handleUpdateTransaction only
assert that rejection happens, but they should also verify the exposed error
message to cover information leakage. Update the two rejection cases in
update-transaction.test.ts to use the specific message from the validation path
(for example, the “provide at least one field” and “not both” cases) so the
tests confirm the intended user-facing error and avoid accidental internal
details. Use the existing handleUpdateTransaction test cases and mockClient
setup as the anchor points.

Consider extracting the repeated write-method success/failure test pattern.
The success/failure-and-audit-log pattern (set resolve or reject → invoke method → assert audit entry shape) repeats nearly identically across all ~9 write-method describe blocks. A small parameterized helper (e.g. testWriteMethod(name, invoke, mockFnRef, ...)) would cut a large amount of duplication while keeping the same coverage.

write-method tests in ynab-client.test.ts repeat the same resolve/reject,

No error-handling test coverage across account tool test files.
All three new test suites (create-account, get-account, list-accounts) only exercise success paths; none validate behavior on invalid input or client-throw scenarios (e.g., zod validation failure, client.getAccounts rejecting). Per path instructions for tests/**/*.ts, error handling paths should be tested for information leakage.

Duplicate monthWith builder.
This helper is duplicated almost verbatim in overspending-alerts.test.ts. Consider hoisting a shared monthWith/category-builder helper into tests/unit/tools/fixtures/ to reduce duplication across analytics tests.

The monthWith helper is duplicated in another analytics test, so factor it into
a shared builder under tests/unit/tools/fixtures and reuse it from
budget-suggestions.test.ts and the matching test. Keep the existing monthWith
behavior intact by extracting the common category/month construction logic into
a single helper with the same inputs and hidden default handling.

🧹 Nitpick | 🔵 Trivial | 🏗️ Heavy lift
Missing error-path / information-leakage test coverage across the analytics test cohort.
None of the analytics handler test suites in this layer (age-of-money, budget-vs-actuals, cash-flow-forecast, category-balances, credit-card-status, spending-trends, and presumably the rest) include tests for invalid input, client rejection paths, or assertions that thrown errors don't leak internal details (file paths, account/category IDs, stack traces). Given this PR explicitly restores the coverage gate and aims for comprehensive handler coverage, this is a gap worth closing.
As per path instructions, tests/**/*.ts should "Test error handling paths for information leakage."

The analytics test suites are missing coverage for error-handling and
information-leakage behavior, so add negative tests around handler entry points
like handleCashFlowForecast (and the similar analytics handlers in this cohort)
that cover invalid input and rejected client calls. Assert the returned/raised
error shape is sanitized and does not expose internal details such as file
paths, raw IDs, or stack traces, while keeping the existing happy-path
assertions intact.

Missing error-path test coverage.
No test covers getAccountTransactions rejecting or invalid input rejection by the schema. Per path instructions, error handling paths should be tested for information leakage.

17 - 90, Add error-path coverage for handleListAccountTransactions by testing
the failure behavior of getAccountTransactions and schema validation. Extend the
existing describe block to include a case where
mockClient.getAccountTransactions rejects and assert the handler returns the
expected safe error response without leaking internals, and another case that
passes invalid input so the schema rejection path is exercised. Keep the
assertions focused on the handleListAccountTransactions function and MockClient
