jest-runner is not working with even a simple project

[tylermurry]

Summary

I am trying to include Stryker into a project that uses Jest, but I'm running up against problems with even the simplest of projects. To demonstrate this, I have created a dead-simple node project that uses Jest and generates the following issue:

• Repo: https://github.com/tylermurry/stryker-jest-runner-issues-2071

Hi! This seems to be a duplicate of #1983

Support for Jest 25 will be released with v3 of Stryker. For now, please downgrade to Jest 24 or wait for v3 of Stryker, sorry!

[simondel]

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

Still not working with Jest version > 24. I was using jest version 26 I need to downgrade to version 24 to get it working. Stricker version 3.3.1.
