Oban Pro: assert_enqueued for structured jobs?

[fireproofsocks]

I’m working with Oban Pro’s new structured jobs feature, and I noticed that some tests using assert_enqueued broke, specifically because of the args.

I’m overriding the new/2 function so I can enqueue structs, so something like this works:

assert {:ok, %{}} = perform_job(MyStructuredJob, my_struct)

But the following does not because my_struct (an Ecto struct) does not implement the Jason.Encoder protocol:

assert_enqueued worker: MyStructuredJob,
                       args: my_struct,
                       queue: :my_queue

I get a Protocol.UndefinedError. I could manually map my_struct to a map of args with string keys, but that defeats the purpose of wanting wall-off the knowledge of how the struct is processed/enqueued. Is there some way around this?

You don’t need string keys, but it does need to be a regular map. Use Map.from_struct/1 or select a subset of the fields to assert with, it can match on partial fields.
