AssertSame vs AssertEqual in PHPUnit

When you’re testing inside of your PHPUnit test methods, you will use many assert-based methods. Two that are seemingly very similar are assertSame() and assertEqual()

The difference between these is the same as the difference of === and == in PHP. One is equal and one is identical.

assertSame is the closest to identical comparison that you can use. So, when you have a choice, use assertSame() instead of equals. This will help catch type mismatches as well.
