Jest import statement: 'TypeError: Cannot set property 'fillStyle' of null'

问题

I type:

npm test

and I get:

It's interesting to note that the import statement works inside the BootScene.test.js file but it doesn't work in the imported file.

I focused on the import statement not working under JEst. So I thought maybe it has something to do with Ecma Script version jest uses. So I tried this solution but the error persists.

This is the repo/branch of this question.

When I type npm start. Everything flows swiftly and with no errors.
