All my jest typescript tests fail in my travis pipeline throwing the following error:



TypeError: Cannot assign to read only property 'Symbol(Symbol.toStringTag)' of object '#<process>'


This happened suddenly without me changing anything particular in the code. And locally everything works fine.



Any ideas what could be happening ?

That is a bug that came with node v11.11. You can downgrade to v11.10 or wait for the fix which facebook has already pushed https://github.com/facebook/create-react-app/issues/6591



If your problem is TravisCI related then you can set a fixed version which works:



node_js:
 - "11.10.1"

You can also upgrade your version of jest to 24.3.0 which has this issue fixed. I believe this is a more future proof solution than downgrading your node.
