New LDATE/LTIME types are not supported.

FB_TestSuite.AssertEquals_LDATE does not exist

There is no built in way to assert an LDATE

LDATE
LDATE_AND_TIME
LTIME_OF_DAY
are not supported.

You can always use AssertEquals() which will compare any data types. Only downside is, the printed error won't be in the provided format and the assertion can't be made with non-variable types (direct comparison with literals).

Also, the LDATE/LDATE types are not supported by TwinCAT < 4026.0. As it stands now, most are still on < 4026.0, so upgrading TcUnit to a compiler that only supports 4026.0 or later isn't a great idea.
Support for this will be added when the whole TcUnit toolchain is upgraded to use VS2022 and 4026 only.

That's fair, I'm using CoUnit, and 64 bit date and time types have been in the codesys compiler for quite a while.
