so the lifetime silently depended on whatever JwtModule happened to be configured with. If the module ever registers without signOptions.expiresIn, the resulting token carries no 'exp' claim and never expires - and since this is also the path that mints the 7-day refresh token, a leaked access token would be valid indefinitely and logout could not meaningfully revoke it. Now passes ACCESS_TOKEN_TTL explicitly. AuthService.register/login reference the same constant instead of their own "15m" literal, so the two services cannot drift apart again. The refresh token expiry now references REFRESH_TOKEN_TTL_MS - the same 7-day value as before, unchanged.

Rewritten against the current implementation and moved to src/core/auth/email-linking.service.spec.ts. The Wallet repository is now the primary seam, the mocks are constructed rather than spied onto a shared instance, and coverage is widened to the paths that were previously untested: token shape/expiry on initiation, an unknown wallet, a verification whose wallet has since been deleted, and getUserByEmail's normalisation.

the spec provided two, so the testing module would not have compiled. - verifySignatureAndIssueToken requires the wallet to already be linked to an account ("Wallet not linked to any account"). The spec expected success with no wallet record at all. Replaced by src/core/auth/wallet-auth.challenge-flow.spec.ts, which keeps the original intent - the challenge -> sign -> verify -> validate flow - against the current service. All eight dependencies are provided, and expiry/provenance assertions are added for both the success and failure paths. This is kept separate from the existing wallet-auth.service.spec.ts rather than merged into it: that suite stubs `ethers.verifyMessage` out entirely to test wallet bookkeeping, whereas this one needs real signatures to test the authentication path. The two do not overlap. Coverage added while repairing: challenge uniqueness per request, the payload handed to jwtService.sign, provenance records on success and on failure, a non-challenge message, and a valid signature from a wallet that is not linked to any account.

On inspection the file is not a duplicate at all - it is unrunnable: - it ends with a stray `` line, so it is not valid TypeScript; - its imports resolve `../../user/entities/user.entity` and `../../auth/...`, which from test/ point outside the repository - it was written for a location it never lived in; - ts-jest reports type errors as failures, so it could not have passed even once it was reachable. It is therefore deleted rather than merged. What it was *trying* to cover - register() and login() - was not covered anywhere, so that is picked up by the new src/core/auth/enhanced-auth.service.credentials.spec.ts: - the register/login guard rails (duplicate email, duplicate username, unknown referral code, wrong password, deactivated account, wallet-only account), none of which had any coverage; - the login timestamp write; - refresh-token rotation, including that the old token is revoked and replaced, that an expired or unknown token is rejected without revoking anything, and that a refreshed access token is only 2FA-verified when the account has no 2FA configured; - revokeAllRefreshTokens() and validateUser(). src/core/auth/enhanced-auth.service.spec.ts is untouched and remains the more complete of the two for the 2FA flows.

It ran in neither suite. It is an end-to-end test, not a unit test: it boots a real Nest application with TypeOrmModule.forRoot({ type: 'postgres', dropSchema: true }), loads OracleModule/AuthModule/UserModule and drives them with supertest. Putting it in the unit suite would have made `npm test` depend on a live Postgres instance. Renamed to test/oracle-e2e.e2e-spec.ts, which is what test/jest-e2e.json's `.e2e-spec.ts$` regex matches. It now runs under `npm run test:e2e`, alongside the eight other e2e specs in test/. test/jest-e2e.json itself is untouched, per the issue's constraint. With this rename, test/ contains no *.spec.ts files at all - every remaining spec there is a *.e2e-spec.ts reachable by the e2e project. Note for reviewers: CI (.github/workflows/build-check.yml) currently runs only `npm test -- --runInBand` and has no Postgres service, so the e2e project - which was already unreferenced by CI before this change - is still not part of the CI gate. Wiring that up is left as follow-up rather than folded in here, since it would newly subject the other eight e2e specs to CI as well.

Both are now derived from `JwtModuleOptions` by indexed access, so a malformed TTL or algorithm is a compile error at the definition rather than a runtime surprise. It also keeps the file honest against the library's own types instead of asserting a looser shape. - `DashboardModule` / `NotificationModule`: the 24h TTL moves into a `LONG_LIVED_TOKEN_TTL` constant so those modules stop re-declaring it. - `payload-signing.service.spec.ts` and `wallet-auth.challenge-flow.spec.ts` declared `let testWallet: Wallet`, but in ethers v6 `Wallet.createRandom()` returns an `HDNodeWallet` - a sibling of `Wallet`, not a subtype, hence the `#private` incompatibility. Both now use the concrete `HDNodeWallet` type.

The spec provided four; PerformanceAnalyticsService, PortfolioConstraintService and AuditLogService were all missing, so the testing module could not have compiled. Those three are precisely the collaborators that gate the behaviour this spec asserts on. - deletePortfolio() now calls `remove()` (a hard delete). The spec asserted a soft delete - status archived, deletedAt set, save called. - restorePortfolio() no longer exists; the restore path is updatePortfolio(id, { status: ACTIVE }). Two tests target a removed API. - addHolding() looks a holding up by `{ portfolioId, ticker }`, not `{ portfolioId, ticker, chain }`, and the spec asserts the old shape. - Every add/update/remove holding test now also traverses validatePortfolioConstraints -> auditLogService.recordVerification and updatePortfolioMetrics -> performanceService.recordSnapshot, none of which the spec mocks. - `type` was dropped from CreatePortfolioDto, `status` moved to the PortfolioStatus enum, and CreateOptimizationDto gained a required portfolioId. Repairing this properly means rebuilding roughly thirty tests against a ~700 line service whose transitive collaborators are unmocked - and with no way to run the suite, there is no way to know whether the rebuilt assertions are actually right. A spec that merely compiles would look finished while almost certainly turning CI red, which is worse than the current honest state. Deleted, with the intent recorded here so it can be picked up as its own task once the suite is runnable. The issue allows exactly this outcome ("runs in the unit suite or is deliberately deleted, with the rationale in the PR"). This is not a duplicate of any existing spec, so no working coverage is lost - only a suite that never ran and could not have. The other two mechanically-moved specs on this branch (payload-signing.service.spec.ts, modern-portfolio-theory.spec.ts) type check cleanly.

The compiler was right to flag it, and it is not only a typing problem. A decorator expression is evaluated once, when the class is defined - not per request - so the arrow function inside it captures whatever `this` is at class-definition time (the class/prototype) and then reuses that for every subsequent request. `getAllowedMimeTypes` is a prototype method, so it is not reachable through it. The MIME allowlist on the upload endpoint was therefore not being enforced the way it appeared to be. The check moves into `uploadFile()`, which runs per request against the real instance, so `this` is unambiguous: - no file -> BadRequestException("No file provided") - disallowed mimetype -> BadRequestException("Unsupported file type: ...") - otherwise -> unchanged, proceeds to storageService.upload() The `limits.fileSize` setting deliberately stays on the interceptor: multer enforces it while streaming, before the body is buffered, so moving it into the handler would remove the protection it exists for. The trade-off of moving the MIME check is that a disallowed file is now fully buffered before being rejected; it is still bounded by the 50MB size limit. Adds file-upload.controller.spec.ts, which is the first coverage this path has had - the absence of a test is the other half of why the defect went unnoticed. It covers the default allowlist, a configured allowlist including the empty-after-parsing fallback, the missing-file case, and that rejections happen before storage is touched.

This is unrelated to the auth and jest work on this branch - the file and tsconfig.json are byte-identical to main - but it blocks the type-check gate, so it is fixed here and flagged as an unrelated change. The compiler was right to flag it, and it is not only a typing problem. A decorator expression is evaluated once, when the class is defined - not per request - so the arrow function inside it captures whatever `this` is at class-definition time (the class/prototype) and reuses that for every subsequent request. `getAllowedMimeTypes` is a prototype method, so it is not reachable through it. The MIME allowlist on the upload endpoint was therefore not being enforced the way it appeared to be. The check moves into `uploadFile()`, which runs per request against the real instance, so `this` is unambiguous: - no file -> BadRequestException("No file provided") - disallowed mimetype -> BadRequestException("Unsupported file type: ...") - otherwise -> unchanged, proceeds to storageService.upload() The `limits.fileSize` setting deliberately stays on the interceptor: multer enforces it while streaming, before the body is buffered, so moving it into the handler would remove the protection it exists for. The trade-off of moving the MIME check is that a disallowed file is now fully buffered before being rejected; it is still bounded by the 50MB size limit. Adds file-upload.controller.spec.ts, the first coverage this path has had - the absence of a test is the other half of why the defect went unnoticed. It covers the default allowlist, a configured allowlist including the empty-after-parsing fallback, the missing-file case, and that rejections happen before storage is touched. --- .../file-upload.controller.spec.ts | 104 ++++++++++++++++++ .../file-upload/file-upload.controller.ts | 41 ++++--- 2 files changed, 127 insertions(+), 18 deletions(-) create mode 100644 src/infrastructure/file-upload/file-upload.controller.spec.ts diff --git a/src/infrastructure/file-upload/file-upload.controller.spec.ts b/src/infrastructure/file-upload/file-upload.controller.spec.ts new file mode 100644 index 0000000..4158570 --- /dev/null +++ b/src/infrastructure/file-upload/file-upload.controller.spec.ts @@ -0,0 +1,104 @@ +import { Test, TestingModule } from "@nestjs/testing"; +import { BadRequestException } from "@nestjs/common"; +import { ConfigService } from "@nestjs/config"; +import { FileUploadController } from "./file-upload.controller"; +import { FileStorageService } from "./services/file-storage.service"; +import { FileCleanupService } from "./services/file-cleanup.service"; +import { FileScanService } from "./services/file-scan.service"; +import { FileMetadataService } from "./services/file-metadata.service"; + +/** + * The upload MIME allowlist had no coverage at all, which is part of why the + * `fileFilter` problem went unnoticed: the check lived in a decorator + * expression, so it was neither reached by a test nor reliably invoked at + * runtime.
