XMLSerializer is not a constructor/is undefined

[patoncrispy]

🐛 Bug Report

While trying to test a class that uses XMLSerializer, I get the error 'XMLSerializer is not a constructor' or 'XMLSerializer is undefined'. I have testEnvironment set to jsdom just in case.

To Reproduce

Add new XMLSerializer(); to a test.

Expected behavior

XMLSerializer should work as expected. Support for it was added to jsdom in v13.

You'll need to use custom jsdom environment, like this one, to use that, as jsdom dropped Node 6 in v12 and we can't go with that currently.

Thanks, @thymikee.

Is this documented somewhere?

Yup, search for custom environment on our docs :)
