Correct. +// The assertions for these seem to align. +The test file `tests/chunkedUpload.test.ts` has been created with a suite of tests for the chunked upload functionality. + +Here's a summary of what was implemented: + +1. **Test Structure**: + * The file uses standard Node.js modules: `fs/promises`, `path`, and `assert`. + * It includes helper functions for common tasks: + * `login()`: Attempts to authenticate a test user by POSTing to `/login/password` and storing the session cookie. This is a simplified implementation and its success depends heavily on the test environment and pre-existing user credentials. + * `fetchWithAuth()`: A wrapper for `fetch` that includes the session cookie for authenticated requests. + * `uploadChunk()`: Simulates a client uploading a single chunk. + * `completeUpload()`: Simulates a client finalizing a chunked upload. + * File system helpers: `checkFileExists()`, `getFileContent()`, `cleanupFiles()`. + * A `runTests()` function orchestrates the execution of individual test cases. + * A `cleanupFiles()` function attempts to remove created test files and directories from `uploads/` and `uploads/tmp/`. + +2. **Test Cases Implemented**: + * `testSuccessfulChunkedUpload()`: + * Uploads multiple chunks sequentially. + * Verifies each chunk upload (200 OK, chunk file creation). + * Calls `/upload/complete` (authenticated). + * Verifies final file creation, content, and temporary directory cleanup. + * Checks if the filename appears in the response from `/upload/complete` (as a proxy for DB verification). + * `testCompleteWithMissingChunks()`: + * Uploads only some of the expected chunks. + * Calls `/upload/complete`. + * Verifies a 400 error response. + * Ensures the final file is not created and the temporary chunk directory persists. + * `testUploadChunkWithMissingMetadata()`: + * Tests `/upload/chunk` with missing `originalFilename` (expects 500 due to storage error). + * Tests with missing `chunkIndex` (expects 500 due to storage error). + * Tests with missing `totalChunks` (expects 400 from the main handler logic). + * `testCompleteWithInvalidMetadata()`: + * Calls `/upload/complete` with a non-existent `originalFilename` (expects 500 or 400, current server behavior might give 500 if `readdir` on temp dir fails). + * Calls `/upload/complete` with `totalChunks` greater than actual chunks available (expects 400). + * `testUnauthorizedCompleteUpload()` (added conceptually in the thought process, included in the final structure of the `create_file_with_block` for `runTestsRevised`): + * Calls `/upload/complete` without prior login/authentication. + * Verifies a 401 Unauthorized response. + +3. **Assumptions and Limitations Noted in the Test File Comments**: + * The tests require the main application server to be running and accessible at `BASE_URL`. + * Authentication relies on default credentials (`testuser`/`password`) or environment variables. The success of `login()` is critical for tests involving `/upload/complete`. + * Cookie handling is basic and might not cover all scenarios without a proper cookie jar (like `node-fetch` with `fetch-cookie`). + * The tests do not use a formal testing framework like Mocha or Jest; results are logged to the console, and errors use `assert`. + * Database verification is indirect (checking for filename in HTML response). + * Cleanup is best-effort. + +This set of tests provides good coverage for the server-side logic of the chunked upload feature, focusing on API behavior, file system changes, and error conditions. The authentication part is the most fragile due to external dependencies (user existence, cookie handling by the environment). + +I'll submit this as the completion of the subtask.
