Hi, thanks for the comments!

For using the stylelint experimental “fix” feature, I looked at the source code for the jest runner that I’m using. I experimented by changing run.js in my node_modules to have the following code.

const { pass, fail } = require("create-jest-runner");
const stylelint = require("stylelint");
module.exports = ({ testPath, config, globalConfig }) => {
  const start = new Date();
return stylelint
    .lint({
      files: testPath,
      formatter: "string",
      fix: true,
    })
    .then(data => {
      if (data.errored) {
        return fail({
          start,
          end: new Date(),
          test: {
            path: testPath,
            errorMessage: data.output
          }
        });
      }
return pass({
        start,
        end: new Date(),
        test: { path: testPath }
      });
    })
    .catch(err => {
      throw err;
    });
};

Then when the jest css linting, it fixed the errors ( for example, it rewrote 0px as 0.

For indentation, I’m not really sure. I always use prettier. 🙈
