Code Review
This pull request refactors the conformance tests to interact with the transport layer directly, which is a solid approach for testing retry logic. The changes also include improvements to the default retry function in the main library. The overall direction is good, but I've identified a few issues, primarily concerning error handling, type safety, and a bug in header manipulation within the test suite. Addressing these will improve the robustness and reliability of the tests.

Code Review
This pull request refactors the conformance tests to use the transport layer directly, allowing for more granular testing of retry logic. The changes are extensive and mostly involve rewriting library methods to make direct REST API calls. I've found a couple of critical issues in the new test setup logic that could lead to runtime errors or incorrect behavior. Additionally, there are a few instances of commented-out code that should be removed for cleanliness. The improvements to the retryable error detection function in src/storage.ts are well-done and increase robustness.

Code Review
This pull request introduces significant refactoring to the conformance tests, primarily to align with Node.js 18 and to test retry logic at the transport layer. The changes involve bypassing high-level SDK methods in favor of direct calls to storageTransport.makeRequest, implementing a complex custom retry strategy, and updating various test helper functions. My review focuses on improving type safety, removing leftover debugging code, and enhancing code clarity in these new implementations.

This function has a few areas for improvement:
- It contains several
console.log,console.warn, andconsole.errorstatements (e.g., lines 139, 141, 166, 171). This logging seems intended for debugging and should be removed from the final test code to keep the test output clean. - It uses
anycasts in multiple places (e.g., lines 156, 169) to access properties on API responses. This bypasses TypeScript's type safety. To improve robustness, please consider defining interfaces for the expected response shapes.

There was a problem hiding this comment.
Attaching response headers directly to the data object via (data as any).headers = plainHeaders; is not type-safe and can be considered an unexpected side effect. While this is likely a workaround to pass headers to higher-level functions for the conformance tests, a cleaner approach would be to return a more structured object from makeRequest. If that's too large of a change, consider adding a TODO comment explaining this pattern or defining a specific response type that includes headers to avoid using any.
All 720 test cases have been fixed, and the code has been refactored.

Code Review
This pull request refactors the conformance tests to use a lower-level transport layer for making requests, which provides better control for retry tests. The changes also include a more sophisticated and specific retry logic in the StorageTransport. The overall direction is good, but I've found a few areas for improvement: some test helper functions are still using the old SDK methods, and there's a potential bug in header handling within the transport layer. Additionally, the new retry logic could be refactored for better readability.

The new shouldRetry function is very large and implements complex retry logic. To improve readability and maintainability, consider refactoring this function by breaking it down into smaller, more focused helper functions based on the request type (e.g., for mutations, for idempotent requests).
- Replace high-level bucket and file calls with storageTransport.makeRequest. - Fix Scenario 1 failures by implementing "create-or-get" logic for buckets. - Resolve metageneration mismatch in lock() by dynamically fetching metadata. - Normalize header keys to lowercase in transport response processing. - Increase unit test coverage for shouldRetry logic and error handling.
