__getitem__ of AsyncMock returns MagicMock instead of AsyncMock

[darrikonn]

Actual

info.context.data_loader["organization"] yields MagicMock

Expected

info.context.data_loader["organization"] yields AsyncMock

Test case

ipdb> info
<AsyncMock id='4411944080'>

ipdb> info.context
<AsyncMock name='mock.context' id='4593499664'>

ipdb> info.context.data_loader
<AsyncMock name='mock.context.data_loader' id='4591705360'>

ipdb> info.context.data_loader["organization"]
<MagicMock name='mock.context.data_loader.__getitem__()' id='4588173008'>

This is an intentional behavior where child mock is MagicMock/Mock if the method accessed is synchronous in this case __getitem__

Mmm interesting, thanks for clarifying.
I'll need to use a custom AsyncMock class for my use-case.

Same issue/confusion here. Is there a recursive AsyncMock?
