This is better for testing s.toString, but now it doesn't test the << method of s at all. Can we keep both tests here (the truncated and non-truncated versions)?

Updated the test to explicitly verify both the truncated operator<< behavior and the non-truncated toString() output using the larger buffer

Looks good! Can you apply the same change to PrimitiveTest? The two cases (PrimitiveTest, NonPrimitiveTest) should operate in the same way.

Done! I've updated PrimitiveTest to follow the exact same two-case testing pattern, verifying both the truncated operator<< output and the full toString() output.
