I have cloned your repo on my Mac and I couldn't reproduce the issue.

I think there is a problem with your Mac. Did you run the test in a specific environment ?

[inorganik]

A problem with my mac? Hmm.... I rolled jest and ts-jest back to v24 and it works, so it appears to be a problem introduced in a recent version of jest or ts-jest...

I don't believe the module type in tsconfig is the problem, as I have another repo with the same tsconfig and it tests just fine (also on v24 of both jest and ts-jest)

As you can above with WebStorm, I couldn't reproduce the issue. I saw this one somewhere in jest repo before. Not sure how to help in this case because I cannot reproduce the issue.

@ahnpnl which version of node are you at? I have v10.9.0

[ahnpnl]

Oh I am using node 12, maybe you should use node 10.21.0 or higher. I think maybe jest doesn't support node 10.9

[inorganik]

Updating to node v12 fixed it 👍
