Running conduit directly into this type of fixture an splicing in it.

Your terminology is wrong. You are asking about terminating in the fixture or even more accurately connecting to the factory wiring. Article 410 dictates this. 410.20 requires adequate space. Any "unnecessary" splices aren't allowed per 410.54 (D). Conductors and connectors must adequate for the temperature rating per 110. Wiring that runs through the fixture to other loads is subject to additional code restrictions.

Guess putting box next to fixture is best.

Depends on"next to" means.
What are you looking to do or need help figuring out?
I normally put a box next to 4 fixtures and from the one box whip into the fixtures.
 
If you do feed thru you have to make sure the fixture is listed for feed thru
410.64 Luminaires as Raceways. Luminaires shall not be used
as a raceway for circuit conductors unless they comply with
410.64(A), (B), or (C).
(A) Listed. Luminaires listed and marked for use as a raceway
shall be permitted to be used as a raceway.
(B) Through-Wiring. Luminaires identified for throughwiring,
as permitted by 410.21, shall be permitted to be used as
a raceway.
(C) Luminaires Connected Together. Luminaires designed
for end-to-end connection to form a continuous assembly, or
luminaires connected together by recognized wiring methods,
shall be permitted to contain the conductors of a 2-wire branch
circuit, or one multiwire branch circuit, supplying the connected
luminaires and shall not be required to be listed as a raceway.
One additional 2-wire branch circuit separately supplying
one or more of the connected luminaires shall also be permitted.

So if you have a lot of those fixtures surface mounted and job is all EMT wouldn't still use whip to box? Guess your allowed if under 6' whip.by code even if spec calls for all.EMT.

It only needs to be identified, not listed, for feed through. If used as a raceway (what's the difference???) it needs to be listed as a raceway.

I think if you continue the same circuit that feeds the fixture onward to the next fixture, it’s “feedthrough”. If you run an unrelated circuit through the fixture, you are using it as a raceway.

Should be in your spec book if you can use flex/ mc if not 1/2" emt from box to light done all the time, even in Robroy, Plastibond.
