transform not working for windows

Sample Code: https://github.com/VikasAgarwal1984/package-deploy-learn/tree/0.0.1

Issue: Transform not working

Jest config file path https://github.com/VikasAgarwal1984/package-deploy-learn/blob/0.0.1/jest.config.js

To understand what is failing, i updated the index file in node_modules to the content copied in below link: https://github.com/VikasAgarwal1984/package-deploy-learn/blob/0.0.1/dev/index.js

I think the issue is require("${postcssRunner}")(

does not work as everything is Stringified, and ${} flat the '' in windows. so when code gets evaluated it fails. To double check, i debugged with following paths:

// works
    // const postcssRunner = 'D:\\\\git\\\\package-deploy-learn\\\\node_modules\\\\jest-transform-css\\\\postcss-runner.js';
    //const postcssRunner = 'D:/git/package-deploy-learn/node_modules/jest-transform-css/postcss-runner.js';

    // does not work
    const postcssRunner = `${__dirname}/postcss-runner.js`;
    //const postcssRunner = p.normalize(`${__dirname}/postcss-runner.js`);
    //const postcssRunner = 'D:\\git\\package-deploy-learn\\node_modules\\jest-transform-css\\postcss-runner.js';
    //const postcssRunner = 'D:\\git\\package-deploy-learn\\node_modules\\jest-transform-css/postcss-runner.js';


\\\\ gets translate to \\ in  require("${postcssRunner}") and path works.

I tested above Repository in Ubuntu VM, there was no issue, and npm run test works fine. Any insights?

Thanks for your nice report! Maybe using path.join could work?

So something like const postcssRunner = path.join(__dirname, "postcss-runner.js") could do the trick?

I think issue is with below line:

File: https://github.com/dferber90/jest-transform-css/blob/master/index.js

Line No: 71 require("${postcssRunner}")(

We need to preserve'\\', Something like below should work I believe. https://stackblitz.com/edit/web-platform-zoctv4?file=script.js
