(Added) Addition of new methods and tests in Trace class

[MarjovanLier]

User description

Summary

This Merge Request (MR) introduces several enhancements to the Trace class and its associated test suite. The primary changes include adding a new getProfilesDir method, improvements to the generateReport method, and introducing new test classes to ensure comprehensive testing coverage.

Context and Background

As the project evolves, it is crucial to maintain a robust codebase and adhere to best practices. This MR aims to improve the overall quality, maintainability, and testability of the Trace class and its related components.

Problem Description

Previously, there were no dedicated tests for the enableXhprof and setProfilesDir methods of the Trace class. The generateReport method also lacked proper input validation and error handling.

Solution Description

To address these issues, the following changes have been implemented:

1. A new getProfilesDir method has been added to the Trace class, allowing retrieval of the directory path where profile data files are stored.
2. The generateReport method has been enhanced with input validation and error handling. It now sanitizes the filename using htmlspecialchars and checks for empty strings and the value '0' before attempting to read the file.
3. A new test class EnableXhprofTest has been introduced to test the functionality of the enableXhprof method in the Trace class.
4. Another test class ProfilesDirTest has been added to test the setProfilesDir method in the Trace class.
5. The namespace of the IsExcludedClassTest test class has been updated to align with the project's test directory structure.

List of Changes

• Added:
  • src/Trace.php: New getProfilesDir method.
  • tests/Unit/EnableXhprofTest.php: New test class for the enableXhprof method.
  • tests/Unit/ProfilesDirTest.php: New test class for the setProfilesDir method.
• Changed:
  • src/Trace.php: Improved input validation and error handling in the generateReport method.
  • tests/Unit/IsExcludedClassTest.php: Updated namespace for better organization.

Tips

### Chat There are 3 ways to chat with CodeRabbit: - Review comments: Directly reply to a review comment made by CodeRabbit. Example: - `I pushed a fix in commit .` - `Generate unit-tests for this file.` - `Open a follow-up GitHub issue for this discussion.` - Files and specific lines of code (under the "Files changed" tab): Tag `@coderabbitai` in a new review comment at the desired location with your query. Examples: - `@coderabbitai generate unit tests for this file.` - `@coderabbitai modularize this function.` - PR comments: Tag `@coderabbitai` in a new PR comment to ask questions about the PR branch. For the best results, please provide a very specific query, as very limited context is provided in this mode. Examples: - `@coderabbitai generate interesting stats about this repository and render them as a table.` - `@coderabbitai show all the console.log statements in this repository.` - `@coderabbitai read src/utils.ts and generate unit tests.` - `@coderabbitai read the files in the src/scheduler package and generate a class diagram using mermaid and a README in the markdown format.` Note: Be mindful of the bot's finite context window. It's strongly recommended to break down tasks such as reading entire modules into smaller chunks. For a focused discussion, use review comments to chat about specific files and their changes, instead of using the PR comments. ### CodeRabbit Commands (invoked as PR comments) - `@coderabbitai pause` to pause the reviews on a PR. - `@coderabbitai resume` to resume the paused reviews. - `@coderabbitai review` to trigger a review.

PR Code Suggestions

Category	Suggestions
Enhancement	Use specific exceptions for error handling instead of returning empty arrays. ___ **Consider using a more specific exception than a generic return of an empty array when the $filename is invalid or the file does not exist. This will help in debugging and understanding the flow of the program better.** [src/Trace.php [170-171]](https://github.com/MarjovanLier/XhprofTrace/pull/31/files#diff-15329b36f4764bd79867bdc947704d9b2afcb82fd7627bd305ae5865be6fb833R170-R171) ```diff if ($filename === '' || $filename === '0' || !is_file($filename)) { - return []; + throw new InvalidArgumentException("Invalid filename or file does not exist: $filename"); } ```
	Validate filenames using patterns instead of HTML sanitization. ___ **Sanitizing the $filename variable using htmlspecialchars might not be necessary or might be misplaced if the filename does not contain HTML characters. Consider validating the filename against a list of allowed characters or paths instead.** [src/Trace.php [168]](https://github.com/MarjovanLier/XhprofTrace/pull/31/files#diff-15329b36f4764bd79867bdc947704d9b2afcb82fd7627bd305ae5865be6fb833R168-R168) ```diff -$filename = htmlspecialchars($filename, ENT_QUOTES, 'UTF-8'); +if (!preg_match('/^[a-zA-Z0-9_\-\/.]+$/', $filename)) { + throw new InvalidArgumentException("Invalid filename: $filename"); +} ```
	Add assertions to validate the metrics values in the test. ___ **To ensure the test is more robust, consider adding more assertions to check the values of 'ct', 'wt', 'cpu', 'mu', and 'pmu' to ensure they meet expected criteria, not just their existence.** [tests/Unit/EnableXhprofTest.php [36-40]](https://github.com/MarjovanLier/XhprofTrace/pull/31/files#diff-e61fbf200dbcc4e83dfaa9d57c590e6d22cb3cf8e18e5d55cf510d9c53f3e4aeR36-R40) ```diff $this->assertArrayHasKey('ct', $xhprofDisable[self::MAIN]); +$this->assertGreaterThan(0, $xhprofDisable[self::MAIN]['ct']); $this->assertArrayHasKey('wt', $xhprofDisable[self::MAIN]); +$this->assertGreaterThan(0, $xhprofDisable[self::MAIN]['wt']); $this->assertArrayHasKey('cpu', $xhprofDisable[self::MAIN]); +$this->assertGreaterThan(0, $xhprofDisable[self::MAIN]['cpu']); $this->assertArrayHasKey('mu', $xhprofDisable[self::MAIN]); +$this->assertGreaterThan(0, $xhprofDisable[self::MAIN]['mu']); $this->assertArrayHasKey('pmu', $xhprofDisable[self::MAIN]); +$this->assertGreaterThan(0, $xhprofDisable[self::MAIN]['pmu']); ```
Possible issue	Correct the namespace to accurately reflect the directory structure. ___ **The namespace declaration seems to be duplicated with 'Unit' appearing twice. Consider correcting the namespace to match the directory structure accurately.** [tests/Unit/EnableXhprofTest.php [5]](https://github.com/MarjovanLier/XhprofTrace/pull/31/files#diff-e61fbf200dbcc4e83dfaa9d57c590e6d22cb3cf8e18e5d55cf510d9c53f3e4aeR5-R5) ```diff -namespace MarjovanLier\XhprofTrace\Tests\Unit\Unit; +namespace MarjovanLier\XhprofTrace\Tests\Unit; ```
Best practice	Reset the profiles directory to its original value after the test. ___ **It's a good practice to clean up after tests to avoid side effects. Consider resetting the profiles directory to its original value after the test completes.** [tests/Unit/ProfilesDirTest.php [26]](https://github.com/MarjovanLier/XhprofTrace/pull/31/files#diff-f1896be17f3534975a72894a5ef562327081232687331acfc3f7b9cdce221b66R26-R26) ```diff +$originalDir = Trace::getProfilesDir(); Trace::setProfilesDir($tempDir); +// Test assertions here +// Reset to original after test +Trace::setProfilesDir($originalDir); ```
