[QUESTION] - console spy not catching log

[jamessouth]

Hello, I posted this question on SO a couple of days ago but no answers yet, and it looks like you have ended the google group. In my node/esm project testing with ava, nyc and sinon I'm not sure why my spy on console.log isn't noticing a log to the console.

• Sinon version : 7.2.3
• Environment : node 10.15.1, npm 6.5.0, windows 10
• Other libraries you are using: esm 3.2.4, nyc 13.2.0, ava 1.2.1

What did you expect to happen?
In another part of my project I have successfully spied on console.log for call counts and args passed and here I expected the same - acknowledgement via callCount that a message was logged to the console.

What actually happens
callCount is 0 instead of 1, notCalled is true

How to reproduce

test repo here

Getting somewhere! The test passes when you comment out the import statement in main, so I guess this has something to do with esm so I will close this for now.

@jamessouth You might find a lot of info on this issue here and on this follow-up on Stackoverflow. The setup is quite similar (ES6, Ava, ESM).

thank you @fatso83 this issue was actually caused by a bug in esm which has since been fixed with the 3.2.5 release
