`assertEquals` (internally `==`) has its flaws. Let's use stricter assertions as a better practice: - `assertTrue`: `$expected === true` - `assertFalse`: `$expected === false` - `assertSame`: `$expected === $actual` `assertSame` with arrays has other benefit: it ensures the order of the items within the array matches the expectation. In some APIs, that's crucial.
