Lezer testing for error nodes

Lezer
1

This is an example of code and the Ast from my lezer parser:

code: foo.
Ast: ObjectCreationExpression(Identifier,".",⚠)

Is there a way to test this case with fileTests from @lezer/generator/dist/test ?

I understand the test runner fails whenever it find an error node SyntaxError: No parse at X

Maybe testTree supports this (haven’t test it) but it would be nice to use the same approach to test happy/unhappy paths

If there’s a ⚠ character in your expected tree, it won’t.

Will check again if I missed anything, thanks

@jnavb Hi, already solved or not?

@Toly iirc it was a typo on my end, regards.

:grinning_face_with_smiling_eyes: @jnavb BTW, which function do you use to write the unit test? fileTests or testTree?
