I won't be able to tackle this myself, so I'm going to apply the help wanted label

[alexandrebrilhante]

I can work on this. Should the guide be aimed at tests in QuantEcon.jl specifically or julia at large?

[sglyon]

Good question. Could you provide an example of when that would differ?

[alexandrebrilhante]

Testing in julia is briefly introduced in the docs. Did you have something similar in mind? I could work on a notebook to show more test examples.

[sglyon]

I think it makes sense to write a simple document that points to the Julia documentation page and then describes any additional conventions/procedures we have followed here in QuantEcon.

Does that make sense

Is there still some work on this? I can offer some help if I get some directions on what is missing.
