Nx 8 -> 9 Upgrade causes Jest tests to not pass afterwareds

Upgrading from Nx 8 to 9 causes Jest tests to fail with the following error:

I also upgraded:

@angular/material to v9 @angular/flex-layout @nguniversal/express-engine @angular-material-extensions/google-maps-autocomplete

Associated Nrwl deps are v9.4.5

Nothing else was changed other than needing to update the test matching regex so that tests are found.

Let me know what I can provide to help track down what happened during the update.

Just tried this again after upgrading to Nx 10. The test match that comes from the nxPreset require, does the same thing in my repo. No tests are run (as they are not found).

@Cammisuli if you remember our chat over slack about how our test runs take a really long time, I wonder if our repo is just all messed up for some reason and thats why I am getting all these oddities that don’t seem to happen to you guys?

Just tried recreating it using a new workspace going from 8 to 9 and upgrading material. Everything seemed to work fine. Not sure what he difference between that one and mine is (other than the amount of code).

I compared the root jest config that was generated with mine and trimmed some fat (remove the serializers from the root in mine as they didn’t exist in the new one).

Note: the testMatch regex that is generated in a new workspace does not find any tests in my worksapce (for whatever reason)

new: '**/+(*.)+(spec|test).+(ts|js)?(x)' mine: '**/+(*.)+(spec|test).[tj]s?(x)'

Not sure how/why that would differ but something is clearly different that is causing that in mine.
