ng test not passing Jest CLI options any more in v14?

Question

I am using Jest with Angular (instead of Karma). The angular.json file seems to be configured properly, as running ng test works.

According to this article :

You can specify Jest CLI options either in builder options (useful when it is a persistent config) or right to ng test as a parameter (useful when it is a one-timer).

For example to run a single test:

ng test --testNamePattern="My test suite My test case"

This was working before my v14 upgrade, but this is not the case any more. Now if I run:

ng test --testNamePattern="MyComponent"

I get:

Error: Unknown argument: testNamePattern

Note: this is possibly a regression of the builder

Okay quoting @just-jeb from github

It's mentioned in the migration guide . It's a breaking change of Angular CLI, not the builder. camelCase arguments are no longer supported.

Here is therefore the proper way to run the "MyComponent" test

ng test --test-name-pattern="MyComponent"

Note: Jetbrains does not yet (28.06.2022) supports the kebab case arguments
