Repro steps.

For a normal build all the styles from app.styles are preprocessed and included in the styles bundle. How can this bundle be generated and included also in tests (karma)?
Motivation to use styles in test: angular material requires a theme setup to work correctly/not outputting tons of warnings.

I understand the motivation for this feature, but it might be harder than it sounds like due to the way builds are done for tests. I'll look into it if I have the time.

any update on this?

Maybe I missed something, but the following works in my case.

karma.conf.js

module.exports = function (config) {
  config.set({
    ...
    files: [
      './tests/misc/styles.css'
    ],
    ...
  });
};

Also, it could be a path similar to './node_modules/.../bootstrap.css'
