that's certainly also good to have but I actually meant to test fields on the node, both translatable and untranslatable.

So, for untranslatable, you can use just [test_term_reference] (which should show the label in the correct language).

And then add/use a translatable text field, e.g. test_translatable and then verify that you get the correct translation for both [test_translatable] and [test_translatable:value]

I think this field is translatable, that's why it currently works.

As discussed, lets use $langcode instead and use getTranslationFromContext() both on the referenced entity and also further up on the main entity that is passed in when doing other entity tokens.

node_tokens() does the same, for specific tokens.

this is not what I meant :)

A single field, with a translation. Not two fields :) Just fill out test_field in the existing node that you create and add a translation and then add assertions to testing that for the existing token asserts in each langugae and then also a case where you pass in $node but use langcode => 'de'. That's all.

Also, typo (a very consistent one ;)): deustch.

Really close now :)

   can we add one more assert for test_term_reference:entity:term_field, just to make sure this works as well?

   $active_langcode is only used if you go inside the if. so you can move that inside and assign $langcode directly in that case.
