stryker-js: npx stryker run with Jest does not work

Summary

I was running the 0.34.x version previously in my project. I have since removed all traces to stryker, installed the new @stryker-mutator/core and proceeded to use the npx stryker init to install the dependencies and try to get stryker working in my environment with Jest and Yarn.

While my Jest tests all run normally, I get errors running stryker: npx stryker run stryker.conf.js. The error indicates that test files were not found.

11:49:51 (11656) WARN ChildProcessProxy Child process [pid 13664] exited unexpectedly with exit code 1 (without signal). Last part of stdout and stderr was: No tests found, exiting with code 1 Run with --passWithNoTests to exit with code 0 No files found in C:\Users\stevens\Development\TestScripts\Emulator.stryker-tmp\sandbox1586172. Make sure Jest’s configuration does not exclude this directory. To set up Jest, make sure a package.json file exists.

  });
};
