ex_machina + stream_data

[ibarchenkov]

Hello ex_machina maintainers.

I've discovered that data for Ecto factories could be generated using StreamData library. Here's an example. The most compelling thing to me in this approach is that I can define one set of functions and use them simultaneously as Ecto factories in unit/controller tests and as generators in property-based testing.
I have a working solution and almost ready to share it with the community.
Please, consider the following questions:

• Do you want me to contribute such functionality to your project?
• If not, do you mind if I borrow some code in params_for* functions?

Thank you.

Hi @ibarchenkov, thanks for reaching out! I haven't had the chance to use StreamData yet, but property-based testing is something near the top of my list to devote some time into. Given that I'm not familiar with that, I'm not sure I can judge whether what you're talking about would be a good addition to ExMachina or not. So unfortunately I don't think contributing that functionality to the project would be a good idea yet before I can give that some more serious research and thinking.

To your other question,

If not, do you mind if I borrow some code in params_for* functions?

Absolutely don't mind! If you find something useful in the codebase, feel free to copy it.

And maybe once I get more well versed with property-based testing and StreamData, I'll come back here and ask you how it's going!

Either way, thank you for reaching out and asking!
