GOAL
Port a Python integration test for copying files between buckets to TypeScript, adding equivalent vitest tests for the copyFiles function in huggingface.js.
- +0Prompt · +0Write vitest tests in copy-files.spec.ts mirroring a Python test that copies files within the same bucket
- +1mAgent did · +1mExplored existing spec files, copy-files.ts, commit.ts and test consts to understand bucket test conventions and available helpers before writing new tests
- +4mAgent did · +4mWrote initial integration tests for copyFiles into copy-files.spec.ts mirroring the Python test
- +4mAgent did · +4mInvestigated WebBlob/createBlob utilities and removed an unused createBlob import that didn't apply
- +6mAgent did · +6mExpanded the spec with 140 lines of new tests, then cleaned up unused imports, leaving 3 integration tests covering same-bucket copy, folder copy, and related cases
- +7mAgent did · +7mRan tsc --noEmit type check; confirmed pre-existing unrelated errors (missing xetchunk-wasm dependency) and that new tests compiled cleanly
- +8mPrompt · +8mok, commit it
- +10mFail · +10mSecond commit attempt failed with 'nothing to commit' since the change was already committed in a prior run
- +10mOutcome · +10mCommitted 139 insertions across 3 new integration tests for copyFiles in copy-files.spec.ts
VERDICT
I'd start by pointing the agent straight at existing bucket-related test files and the commit.ts/WebBlob utilities so it skips the long exploration phase. The type-check step before committing was the useful correction — it caught unused imports and confirmed no new errors were introduced. Next time I'd also just check git status before re-running the commit command to avoid the redundant 'nothing to commit' error.
