Because Jest@24 has some bug, we are unable to support it for the time being.
see jestjs/jest#7724

We will merge this PR as soon as possible after the jest fix version release. cc @Greg-oliver99 @RoiEXLab

@xiaoyuhen we can't do that. If we do, the project will only work with Jest v24+. I think we should wait a little before doing it.

@neoziro

yeah, we need to wait until jest@24 is stable before considering support.

If we consider supporting jest v24, maybe we need to release a 4.x version. The jest-puppeteer 3.x version supports jest v22~23, and the 4.x version supports jest v24+.

@xiaoyuhen could you fix tests? I would like to release a new major this week with Jest 24 support.

@neoziro

The travis-ci has this error

error sane@3.1.0: The engine "node" is incompatible with this module. Expected version "6.* || 8.* || >= 10.*".

see https://travis-ci.org/smooth-code/jest-puppeteer/jobs/491494756#L515

Should we remove the support of node 9?

[gregberge]

@xiaoyuhen yeah, please add support only for node 8 & 10. v9 should not be used.

@neoziro

Support for the jest v24 has been completed. If there are any suggestions, please let me know.

[gregberge]

Thanks!

Sitting on edge for the npm publish, can't wait. ;) Thanks, for a nice package, soon I can run my tests again.
