Doesn't work with Angular 12.2 anymore

[rainerhahnekamp]

Describe the bug
When I create a new Angular application and apply the schematics, the tests immediately fail.

Schema validation failed with the following errors:
Data path "/polyfills" must be array.
npm ERR! code ELIFECYCLE
npm ERR! errno 1
npm ERR! [email protected] test: `ng test`
npm ERR! Exit status 1
npm ERR! 
npm ERR! Failed at the [email protected] test script.
npm ERR! This is probably not a problem with npm. There is likely additional logging output above.

npm ERR! A complete log of this run can be found in:

This problem is linked to angular.json validation
You can fix this by changing the test build configuration
"polyfills": "src/polyfills.ts", -> "polyfills": ["src/polyfills.ts"],
"inlineStyleLanguage": "scss", -> "inlineStyleLanguage": ["scss"],
Here is the test config that should be generated

"test": {
    "builder": "@angular-builders/jest:run",
    "options": {
      "polyfills": ["src/polyfills.ts"],
      "tsConfig": "tsconfig.spec.json",
      "inlineStyleLanguage": ["scss"],
      "assets": [
        "src/favicon.ico",
        "src/assets"
      ],
      "styles": [
        "src/styles.scss"
      ],
      "scripts": []
    }
  }

Could this be an issue with the angular jest builder? Not sure where schema validation happens. I also had to change "assets" into an array of strings.

I publish the correction on a new package npm :
https://www.npmjs.com/package/@patoudss/jest-schematic

Juste do :

ng add @patoudss/jest-schematic
