Testing includes

Rails

Should one be testing things like ‘include FooBar’ when testing a model?

  • Where FooBar is an externally maintained and separately tested module.

Thanks,

My rule of thumb is to write tests that protect me from / let me
refactor
the layer ‘below’. So in this case, for example, I’d write unit tests
for
the things I was doing in my model that depend on the included module to
‘protect’ me if 1) I decide to use a new library for that functionality,
or
2) there’s an update to that module and I want to make sure the changes
to
it haven’t adversely affected my app, or 3) the include statement in the
model somehow gets deleted.

HTH,
Bill
