Walkthrough

The changes update tests/http/RequestTest.php by simplifying CSRF-related tests, adding a new test for authentication credentials when no data is present, refining assertions for null values, and improving docblock annotations for exception documentation. No core test logic was altered except for loop removal and the new test addition.

Changes

Cohort / File(s)	Change Summary
Test Logic Simplification & Enhancement tests/http/RequestTest.php	Loops in CSRF tests replaced with direct assignments; new test method for authentication credentials with no data; assertion style improved for null checks; docblock annotations added or updated for exception documentation; redundant annotation removed.

Poem

A bunny hopped through test arrays,
Tidying loops and docblocks' maze.
With nulls now clear and auth in check,
The code feels smooth—no need to fret!
🐇✨
Each test refined, the garden grows—
Hooray for code that always knows!

Learning: In yii2-extensions/psr-bridge, expired cookies should not be hashed/validated because they are deletion cookies meant to remove existing cookies from the client browser. The validation logic should only apply to live cookies (expire=0 or expire >= current time) and skip validation for both the special Yii2 deletion case (expire=1) and regular expired cookies.

Learning: In the yii2-extensions/psr-bridge project, the base TestCase class already handles $_SERVER cleanup in setUp() and tearDown() methods, so individual test methods that extend TestCase don't need manual $_SERVER restoration.

Learning: The TestCase class in yii2-extensions/psr-bridge automatically handles $_SERVER superglobal cleanup by saving its original state before each test and restoring it afterward in setUp() and tearDown() methods. Manual $_SERVER cleanup in individual test methods is unnecessary when extending this TestCase.

Learning: In yii2-extensions/psr-bridge, the ResponseAdapter::formatCookieHeader() method uses `$expire !== 1` to skip validation for Yii2's special deletion cookies, but this should be extended to handle all expired cookies, not just the special case where expire=1.

🔇 Additional comments (6)

tests/http/RequestTest.php (6)

11-11: LGTM! Import additions support new functionality.

The added imports are necessary for the new test method and docblock annotations.

Also applies to: 17-18

---

342-359: Good simplification! Removed unnecessary loop structure.

The direct assignment approach is cleaner and more readable than looping over a single-element array while maintaining identical test coverage.

---

395-411: Consistent simplification pattern applied correctly.

Removing the single-element loop improves readability while preserving test functionality, consistent with the previous CSRF test refactoring.

---

464-521: Excellent addition! Comprehensive edge case coverage for authentication.

This new test method provides thorough coverage of scenarios where getAuthCredentials() should return [null, null], including:

• No authentication data present
• Non-Basic authentication schemes
• Empty or incomplete Authorization headers

The test structure follows existing patterns and uses appropriate $_SERVER manipulation techniques.

---

539-539: Good improvement! Using semantically correct assertions.

Replacing assertSame(null, ...) with assertNull(...) is the preferred PHPUnit approach for null value assertions and provides better readability and error messages.

Also applies to: 567-567

---

579-579: Valuable documentation enhancement! Exception annotations improve developer experience.

Adding @throws annotations provides better IDE support and documents the expected exceptions that these test methods might encounter, following PHPDoc best practices.

Also applies to: 992-994, 1010-1012, 1444-1446
