Repro steps

• Create a scss-partial in a folder styles, e.g. _variables.scss
• Add styles to stylePreprocessorOptions.includePaths in .angular-cli.json.
• Use this scss-partial in any *.component.scss-file, using @import "variables"

Observed behavior

Runing ng serve works as expected, running ng test fils with
File to import not found or unreadable: variables.

Desired behavior

The unit tests (ng test) should also use the setting and therefore be able to resolve the _variables.scss.

Mention any other details that might be useful (optional)

This has already been reported in #4200, but this issue has been closed in favor of #3605.
That issue in turn, has been closed in february, however it does not seem to be fixed or is broken again.

Hi, any news please ?

[dereklin]

I was wondering why stylePreprocessorOptions didn't work on unit tests no matter what path settings I tried...

Angular CLI 1.7.3

Bumping this as I have experienced this issue as well.

We're basically unable to use the includePaths feature at all if it does not work with ng test.

In Angular CLI 6 you just have to add the stylePreprocessorOptions to the options block of test:

        "test": {
          "builder": "@angular-devkit/build-angular:karma",
          "options": {
            ....
            "stylePreprocessorOptions": {
              "includePaths": [
                "src/styles",
                "libs/ui/styles",
                "libs/ui/styles/abstracts"
              ]
            }
          }
        },

Closing as it has been answered above.
