[Bug]: Exported enums not working on tests #3397

Open ibesora opened 2 years ago

ibesora commented 2 years ago

Version

27.1.4

Steps to reproduce

Expected behavior

Tests should pass

Actual behavior

Tests fail with TypeError: Cannot read property 'Above' of undefined

Debug log

See it here It was too long to add it here

Additional context

It seems to be a regression of https://github.com/kulshekhar/ts-jest/issues/281 I can update the protomaps package if needed but it doesn't look like it's doing anything weird Setting isolatedModules to false doesn't change anything

Hi, any update on this?

We just noticed this while working on Jest 28 support, will try to fix this issue.

ibesora commented 2 years ago

Any update on this? Can't test an important part of our app without this. Thanks!

Also facing the same issue, hope it will be fixed soon.

Please fix this, it's affecting our core testing functionality

Hey, any update on this one? I can confirm tests still fail using ts-jest v28.0.8 with jest v28.0.3 and v28.1.3. Thank you!

I am facing the same problem on version 28.0.1, @ahnpnl is there any update on this?

the protomaps does not do preserveContEnums in the tsconfig, so it is not preserved in the transpiled output you can't import something that is not there

That doesn't seem to make a difference at all.

I'm having the same problem. It could be a Circular imports issue. However, I am still trying my test to find or come up with a solution.

I've had success mocking the enum and returning an object instead.

Can you show your solution ? I'm having this frustrating issue too.
