Tests don't work anymore

[fbrckman]

Blame Bart. And Babel.

All the test suites failed to run, each with the same error message:

Requires Babel "^7.0.0-0", but was loaded with "6.26.3". If you are sure you have a compatible version of @babel/core, it is likely that something in your build process is loading the wrong version. Inspect the stack trace of this error to look for the first entry that doesn't mention "@babel/core" or "babel-core" to see what is calling Babel.

• Issue on this issue
• Tried this, still nothing.
• babel-upgrade seems to work wonders for some people, but not for me.
• Tried this, did not work.
• Apparently, babel changed their package naming convention as of version 7.. However, I can't seem to find @babel/jest, among other packages.

Babel likely doesn't transpile correctly before running tests which causes a syntax error after "import" keyword.
