Explanation
The PR adds
src/bundles/flashdata/tests/test_flashdata_components.py, which follows the backendtest_*.pyconvention. The tests exercise all 15 capability entries, all documented examples, component and Agent-tool paths, validation, credentials, HTTP errors, retries, download submission, job status/result handling, extension loading, and connected Graph/Parser execution. The release inventory test also covers the new opt-in distribution. These are substantive tests, not placeholders.
Full details: Test Quality And Coverage
-
Explanation
Tests provide strong behavioral coverage. The new pytest module uses async test functions, and repository configuration sets pytest-asyncio to auto mode. Parameterized tests exercise all 14 realtime capabilities through direct components and Agent tools, connected Graph/Parser execution, all 15 documented examples, and all 17 extension registrations. Tests assert request payloads, headers, outputs, credential boundaries, defaults, validation-before-request behavior, redacted HTTP errors, timeout handling, no retries, paid-download authorization, storage redaction, job lifecycle, and trusted result URLs. The API paths have both success and error cases. The frontend change is a declarative sidebar registration, with existing Jest coverage for the sidebar bundle list.
Full details: Excessive Mock Usage Warning
-
Explanation
PASS: Mocking is limited to external HTTP responses and network/environment safety. The tests use
httpx.MockTransportwhile executing the realClient, components, Agent tools, Graph/Parser paths, extension loading, and examples. NoAsyncMockorMagicMockreplaces core logic, and the tests assert request payloads, headers, call counts, validation, redaction, and lifecycle behavior.

Allow underscores in GCS bucket names
The shared bucket regex allows only [a-z0-9.-]. Google Cloud Storage bucket names can also contain underscores, for example my_bucket. This validator rejects a valid GCS destination before submission, and the user cannot work around the check. Allow _ when kind == "gcs".

Add an opt-in FlashData bundle for fetching Google and YouTube data in Langflow flows and agent tools. For example, a research flow can query Google Search, preserve the structured response and pass it through a Parser; Tool Mode exposes the primary query to the agent while API credentials and source options stay configured on the component.
The bundle provides 15 capabilities as 17 components, with separate submit, status and result readers for asynchronous YouTube delivery. Submission requires an explicit operator setting and customer-storage credential. Requests do not automatically retry or poll; result reads validate the authenticated storage origin and do not forward the API Key. Installation is free; API usage, model-provider usage and customer storage have separate costs.
This targets
release-1.13.0and follows the current standalone bundle layout undersrc/bundles. It registers the extension, opt-inbundlesextra, release inventory and frontend menu without adding a default dependency. Fifteen task documentation pages plus a bundle overview explain inputs, output, runnable flow examples, credentials, costs and limitations. The package has not been published to PyPI.Validation:
Prepared with AI assistance and reviewed against FlashData's API contracts. These are proposed component/docs additions; they do not claim existing official catalog approval or published template entries.

Review follow-up (2026-10-18)
descriptionfrontmatter from all 15 task pages, leavingtitleandslug.FLASHDATA_DOWNLOAD_JOB_IDto both the download example setup and its guide. The example only reads status.For the GCS bucket-name comment: native GCS supports underscores, but FlashData's current backend validator rejects them. An offline check against that validator accepts
review-bucketand rejectsreview_bucket. Broadening only this client would send requests that fail server validation. Kept the current provider contract and documented the limitation in the download guide and a code comment; this does not claim broader GCS support. Changing the provider API is a separate product change.Validation for this revision: 98 socket-blocked tests passed; Ruff format/check passed; full Docusaurus build passed with the existing unrelated OpenAPI/anchor warnings. Runtime Python AST is unchanged (only documentation, a docstring and one explanatory comment changed). No live API, model or customer-storage operations.
The previous CI run's Python 3.14 Group 2 test
test_paused_time_does_not_count_against_compute_timeout[sqlite]timed out under its 1-second budget; the performance summary and overall CI gate failed downstream. The rerun API previously required repository admin rights. No timeout assertion or execution behavior was changed to mask this failure; the new revision is subject to fresh CI.
