Summary

PHPUnit 13 introduces dedicated array-comparison assertions whose method names encode three dimensions: comparison strictness (identical vs equal), key handling (considered vs ignored), and order sensitivity. This PR adopts them where the test suite was comparing arrays via the general-purpose assertSame/assertEquals.

The project already required phpunit/phpunit: ^13.0, so no dependency change was needed — only the assertion call sites.

Changes

Mapping applied (faithful to the previous === / == semantics, with known fixed key order):

  • assertSame(array, array)assertArraysAreIdentical (strict, keys considered, order significant)
  • assertEquals(array, array)assertArraysAreEqual (loose, keys considered, order significant)

Converted call sites:

File Was Now
tests/Unit/WritableEventNormalizerTest.php:38 assertEquals assertArraysAreEqual
tests/Integration/EventStoreTest.php:226 assertSame assertArraysAreIdentical
tests/Integration/EventStoreTest.php:279 assertSame assertArraysAreIdentical
tests/Integration/EventStoreTest.php:307 assertSame assertArraysAreIdentical
tests/Integration/EventStoreTest.php:400 assertEquals assertArraysAreEqual
tests/Integration/EventStoreTest.php:424 assertEquals assertArraysAreEqual

Deliberately left untouched

The new assertions require both arguments to be typed array. Two array comparisons were kept as-is to avoid PHPStan level 7 friction:

  • EventStoreTest.php:308getMetadata() returns ?array (nullable)
  • EventStoreTest.php:168json_decode(..., true) returns mixed

WritableEventCollectionTest.php:52 compares two JSON strings, not arrays, so it is not a candidate.

Verification

make before-push passes: cs-fixer clean, 104 tests / 260 assertions green, PHPStan level 7 with no errors.

PHPUnit 13 introduces dedicated array-comparison assertions whose names
encode comparison strictness, key handling and order sensitivity. Replace
generic assertEquals/assertSame calls that compare arrays with the precise
equivalents:

- assertSame(array, array)   -> assertArraysAreIdentical (strict, keys, order)
- assertEquals(array, array) -> assertArraysAreEqual     (loose, keys, order)

Assertions whose actual value is nullable (?array getMetadata()) or mixed
(json_decode) are left untouched to keep PHPStan level 7 happy.

The forward/backward iterator tests and the normalizer test compared the
same fixed-type data as the direct read paths, but did so loosely
(assertArraysAreEqual). Since the values are strictly typed strings/arrays
with no loose-coercion intent, tighten them to assertArraysAreIdentical so
the same data is asserted with identical strictness across all call sites.

Pull request overview

Updates the test suite to use PHPUnit 13’s dedicated array-comparison assertions instead of generic assertSame/assertEquals for array comparisons, aiming to make intent clearer and leverage PHPUnit’s newer APIs.

Changes:

  • Replaced several array comparisons in tests with assertArraysAreIdentical(...).
  • Standardized array assertion usage in unit and integration tests around event data normalization/reading.
