bootstarted / effects Goto Github PK

Dear @izaakschroeder , amazing lib!
please, how should we use Effects to test Aggregate Roots data structures (that contains an apply function to change it's state) ?
see: https://github.com/slashdotdash/commanded/blob/master/test/example_domain/bank_account/bank_account.ex

We would like to make a complete pure test framework for Aggregates and Process Managers.

I have isolated and organized them in a Pure CQRS/ES project, https://github.com/work-capital/ev_sim ,
pls, see account aggregate

Hi,

I've been trying to experiment with the library but I'm stuck with an issue that it can be easily spotted in the documentation:

# Create the computation. 
computation = MessageApp.greet "Fred" 
# Perform the computation. 
MessageInterpreter.Console.handle(computation)

The typespec of computation is MessageEffect.t, however the typespec of MessageInterpreter.Console.handle/1 is MessageEffect.Say.e

When I try to run a minimal example it fails exactly for this reason.
