Strip ng-reflect-* and ng-version in snapshots

Which scope/s are relevant/related to the feature request?

vitest-angular

Information

When switched to Istanbul from V8 as coverage provider our tests stopped passing.
Vitest started generating different snapshots when one of component gets function as its input.

Describe any alternatives/workarounds you're currently using

Don't try serialize functions when creating snapshots

I would be willing to submit a PR to fix this issue

Thanks @k3nsei. You can try this out manually if you still have jest-preset-angular installed.

Add this to the vite.config.ts:

    test: {
      // .. other config
      snapshotSerializers: [
        'jest-preset-angular/build/serializers/no-ng-attributes'
      ]
    },

We'll look at supporting this in the package itself.

I tried the things described here https://marmicode.io/blog/angular-template-code-coverage-and-future-proof-testing and found inconsistent behaviour, resulting in a different snapshot on each test run. So I'm reporting this and asking for a new feature. In my project, I have switched back to V8 as the coverage provider because I cannot leave the project with a broken test suite. I'm seeing a lot of power and new capabilities in Vitest. It will take some time for the integration to mature. But the future looks bright.
