Introspective Functions / Testing? about dry-struct HOT 7 CLOSED

Also - any thoughts on shoulda-like helpers -

expect(SomeStruct).to have_attribute(:attr_name).of_type(SomeType)

would this be desirable? or do you have other thoughts?

ftr, willing to contribute if desired.

@MissingHandle check out rspec-dry-struct, I think this does exactly what you want.

Ah - thanks @AMHOL ! That indeed takes care of the testing need.

What about the introspective functions - any thoughts there? I'm coming across a scenario where I have a specification in a JSON file. Within my code, I want to make sure that values in the JSON are valid according to various structs i've defined. For me, the introspective functions seem unavoidably necessary - would you want them within dry-struct?

@MissingHandle Struct.attribute? and Struct.attribute_names have landed in master :) I'll push a new release next week

@solnic tbh I added this specifically for use at the runtime. FWIW using attribute? is more semantic-full than a plain respond_to? call and attribute_names can be useful for metaprogramming. I wouldn't write a test for a struct, for my taste, it's a waste of time :)

I also wanted the functions for runtime. Though I was asking about it, I might agree with you on the testing.
