test(core): improve assertion usage for better clarity and order

[GOODBOY008]

Changes

Corrected assertion parameter order

Changed from assertEquals(actual, expected) to assertEquals(expected, actual)
Follows JUnit conventions where expected value comes first
Results in clearer failure messages: "Expected: X, but was: Y"

Pull Request Overview

This PR improves test code quality by standardizing assertion parameter order across the test suite to follow JUnit conventions. The changes ensure that assertion failure messages will be clearer by displaying "Expected: X, but was: Y" format consistently.

Key changes:

• Corrected assertion parameter order from assertEquals(actual, expected) to assertEquals(expected, actual) throughout the test suite
• Modernized instance checks by replacing assertTrue(x instanceof Type) with assertInstanceOf(Type.class, x)
• Applied consistent formatting to multi-line assertions
