[Bug]: Unable to get Lit + Jest + Typescript + SWC Jest to work properly

[gethari]

Version

29.7.0

Steps to reproduce

I am trying to use @swc/jest to speed up my tests on my lit+typescript+jest setup. When using the swc/jest as the test runner the willUpdate method is not getting executed. From what I see/find the call stack is different when using ts-jest & it works fine, but on using swc/jest the callstack is missing the _callSuper().

I am attaching a simple repository that can reproduce the issue. Btw here's some screenshots that shows the above, if it is helpful

swc

ts-jest

Expected behavior

swc/jest should not break existing tests & should call lit component lifecycle's willUpdate() method

Actual behavior

willUpdate() method is not getting executed.

Additional context

Not sure if this issue is specific to jest or lit or swc , I have filed the same issue on other repositories as well

• Lit + Jest + Typescript + SWC Jest lit/lit#4580

• Lit + Jest + Typescript + SWC Jest swc-project/swc#8734

Jest only executes code provided by a transformer. Hence, if all works fine with ts-jest, most likely this is not an issue on Jest's side.
