Description
When running ng test on a spec file with several tests in the test suite, then the command fails.
Minimal Reproduction
npx @angular/[email protected] new vitest-repro --defaults --no-routing
cd vitest-repro
npm i --save-dev --save-exact vitest jsdom
Replace the test config in angular.json to use vitest:
"test": {
"builder": "@angular/build:unit-test",
"options": {
"tsConfig": "tsconfig.spec.json",
"buildTarget": "::development",
"runner": "vitest"
}
}Update the default app.spec.ts with the appropriate imports at the top:
+ import { beforeEach, describe, expect, it } from 'vitest';Run the tests with ng test
