TypeError: Cannot read property 'ownerDocument' of null - when using react-test-renderer

[isilweo]

Hey,

#326 broke snapshot testing for me. I can mock rc-slider but this would be against reason snapshot tests are for.

this is line, responsible for error. Maybe it would be enought to add null check here.

@isilweo Look on this issues:
facebook/react#7740
facebook/react#7371
facebook/react#9244
As I understand it, the best idea is to mock it. The last issue is the same problem but with another antd project.

@yesmeck Any suggestion about how to test refs with react-test-rerender?

[yesmeck]

Issues @polkpolio1 post above explain this issue well, anyway I recommend enzyme + enzyme-to-json for React testing, it's recommended on reactjs.org too.

Close since we can not help with this problem.

You may see example of rc-slider itself's test setting:
