After update to Nx 9.2.2, unit test are not executed

Expected Behavior

After update executing unit tests works fine.

Current Behavior

After update unit tests are not being executed. I’m receiving message

No tests found, exiting with code 0

Interesting thing is that when I create application from scratch tests works fine. What I noticed is that changing testMach from

testMatch: ['**/+(*.)+(spec|test).+(ts|js)?(x)'],

to

testMatch: ['**/+(*.)+(spec|test).[tj]s?(x)']

in jest.config.js file solves the problem.

Previous version of jest namely 24.9.0 works fine.

I upgraded a simple project from 8 to 10 - this issue seems to still be there…

Having this regex also fixes it: ['**/+(*.)+(spec|test).+(ts|js)?']

I can confirm this is currently still an issue.

I upgraded from an Angular version 8 project to version 9 using the nx migrate procedure. All goes fine, but the issue is indeed that the testMatch needs to be changed as stated above.

testMatch: ['**/+(*.)+(spec|test).+(ts|js)?(x)']

to

testMatch: ['**/+(*.)+(spec|test).[tj]s?(x)']

I willing to investigate how to automate this in the migration if I can get some help from somebody from the nrwl team if possible.
