It looks like the templated_args change only masked the error last time;
Jest seems broken on Windows with both the patched .24 version, latest
stable, and the new beta version too, presumably because symlinks are
being handled differently on Windows somehow. It might be possible to
hack around the issue by patching the following file, but I'm not sure:
https://github.com/facebook/jest/blob/master/packages/jest-haste-map/src/crawlers/node.ts
- templated_args was missing --node_modules= prefix, and was causing
tests to pass unconditionally
- update to beta of jest 27, which introduces an option to fix the
symlink handling, and is approx twice as fast to start up
