From 3d259c2b223ca80b2ec97e2df2a2d16a3b5d3b00 Mon Sep 17 00:00:00 2001
From: Sergey Biryukov <sergeybiryukov@git.wordpress.org>

Subject: [PATCH] Tests: Use `assertSame()` in some newly introduced tests.

This ensures that not only the return values match the expected results, but also that their type is the same.

Going forward, stricter type checking by using `assertSame()` should generally be preferred to `assertEquals()` where appropriate, to make the tests more reliable.

Follow-up to [49904], [49925], [49992], [50012], [50013], [50065], [50075], [50131], [50150], [50157].

See #38266, #52482.
