Warning

Rate limit exceeded

@armanist has exceeded the limit for the number of commits that can be reviewed per hour. Please wait 3 minutes and 50 seconds before requesting another review.

To keep reviews running without waiting, you can enable usage-based add-on for your organization. This allows additional reviews beyond the hourly cap. Account admins can enable it under billing.

⌛ How to resolve this issue?

After the wait time has elapsed, a review can be triggered using the @coderabbitai review command as a PR comment. Alternatively, push new commits to this PR.

We recommend that you space out your commits to avoid hitting the rate limit.

🚦 How do rate limits work?

CodeRabbit enforces hourly rate limits for each developer per organization.

Our paid plans have higher rate limits than the trial, open-source and free plans. In all cases, we re-allow further reviews after a brief timeout.

Please see our FAQ for further information.

📝 Walkthrough

Walkthrough

Expanded unit test suite for the ErrorHandler class with 249 new lines of test code, covering private behaviors via reflection, exception handling in CLI and web contexts, logging behavior across debug and production modes, and stack trace rendering internals.

Changes

Cohort / File(s)	Summary
ErrorHandler Test Coverage Expansion tests/Unit/Tracer/ErrorHandlerTest.php	Added comprehensive unit tests for ErrorHandler class covering exception handling in CLI and web contexts, debug vs. production mode behavior, logging scenarios, stack trace composition, source code retrieval, error type mapping via data provider, and internal formatting logic. Includes reflection-based helper for invoking private methods and temporary view template creation/cleanup.

Poem

A rabbit hops through error logs with glee,
Testing traces and exceptions so carefully,
With 249 lines of tests so bright,
ErrorHandler coverage shines in the light,
From CLI to web, all paths now gleaming,
Coverage climbing—the rabbit's dreaming! 🐰✨

In `@tests/Unit/Tracer/ErrorHandlerTest.php`:
- Around line 182-205: The temp file cleanup in ErrorHandlerTest uses
createFile(...) then invokes composeStackTrace via invokePrivateMethod(...) and
calls removeFile(...) only after the happy path; change the test to wrap the
invocation/assertions in a try { ... } finally { $this->removeFile($sourceFile);
} so removeFile(...) always runs even on failures, and apply the same
try/finally pattern to the similar temp-file block around lines 287-293.
- Around line 113-117: The test testHandleExceptionCliWritesExceptionMessage
currently calls $this->errorHandler->handleException(new Exception('CLI
failure')) with no assertions; change it to capture and assert the CLI output by
either using output buffering (ob_start/ob_get_clean) around the handleException
call or by mocking/stubbing whatever output/writer dependency the ErrorHandler
uses, then assert the emitted string contains "CLI failure" (or the exact
formatted message) so the test verifies the output behavior of
ErrorHandler::handleException for CLI.
- Around line 275-283: This test mutates FileSystemFactory::instances without
restoring it, risking side effects for other tests; capture the original
instances value from the ReflectionProperty
($instancesProperty->getValue($factory)) before calling setValue, then ensure
you restore it after the test (either in a try/finally surrounding the
mutation/assertion or by resetting it in tearDown) using
$instancesProperty->setValue($factory, $original) so
FileSystemFactory::instances is returned to its prior state.
- Around line 30-40: The test currently overwrites shared view files in setUp
and unconditionally deletes them in tearDown, which can remove real fixtures;
modify setUp/tearDown in ErrorHandlerTest to preserve existing templates by
checking file existence and backing up original content: in setUp, if
traceViewPath or error500ViewPath exist, read and store their original contents
in private properties (e.g., $originalTraceView, $originalError500View) and set
a flag (e.g., $createdTraceView, $createdError500View) when you create a new
file via createFile; in tearDown, if an original content was saved, restore it
(write back the original content) instead of deleting, and only call removeFile
for paths that were actually created by the test (use the created* flags) so
existing fixtures are not lost.
