c# - xUnit test using data coming from external file

In these days I'm trying to understand how xUnit tests work and, in particular, I discovered that there are 3 ways to pass data as parameters in order to test class methods (InlineData, ClassData and MemberData). But here Is my issue: is there any chance to get these data from an external file? (For example a Json file) I wasn't unable to find enough material about this topic, thanks for the attention!

xUnit has been designed to be extensible, i.a. via the DataAttribute.

InlineData, ClassData and MemberData all derive from DataAttribute, which you can extend yourself to create a custom data source for a data theory, in which you may read from you external file and use e.g. Json.NET to deserialize your data.

User Sock wrote about this in his blog regarding JSON, as you mentioned:
