[Jest] crash on Jest 25

[brody4hire]

Summary

I tried upgrading my own package to use Jest 25 in brody4hire/create-react-native-module#240, now the Jest runner crashes. Quick fix workaround for Jest 25 is to use default command runner, with testing time more than doubled for me.

I think this issue is caused by the way Jest 25 changed how it exports its CLI function.

I would personally favor that we make a new major release of the Stryker Jest runner that works with Jest 25 and drop support for any older versions of Jest that would not be compatible.

Here is my output if I try with latest update of Stryker, with HTML reporter removed:

Thanks for opening this issue! It seems like you have the same issue as #1983 so I'm closing this one for now.

Hi! Jest 25 support has been released with @stryker-mutator version 3! You can read all about it here: https://stryker-mutator.io/blog/2020-03-11/stryker-version-3
