Support for component testing on a Gatsby project?

[syntapy]

Is this unsupported or am I doing something wrong? Is it planned to be supported? Here is my WIP codebase.

Basically when I set the bundler to webpack and try to run tests, I get:

> cypress run --component

You are using webpack for your dev server, but a configuration file was not found. We traversed upwards from:

/home/user/repos/mine/frontend/fcc/superformula-lp-clone

looking for a file named:

 - webpack.config.ts
 - webpack.config.js
 - webpack.config.mjs
 - webpack.config.cjs

Add your webpack config at one of the above paths, or import your configuration file and provide it to 
the devServer config as a webpackConfig option.

My cypress.config.js is

import { defineConfig } from "cypress";

export default defineConfig({
  e2e: {
    baseUrl: "http://localhost:8000",
    setupNodeEvents(on, config) {
      // implement node event listeners here
    },
  },
  component: {
    devServer: {
      framework: "react",
      bundler: "webpack",
      return: {
        port: 8000,
        close: () => {},
      }
    },
    indexHtmlFile: "./cypress/support/compnent-index.html",
    supportFile: "./cypress/support/component.ts",
    specPattern: "./src/components/__tests__/**/*.spec.tsx",
  }
})

I know gatsby uses webpack

I tried a couple things such as setting bundler to

• require("node_modules/gatsby/webpack.d.ts")
• require("@cypress/webpack-dev-server")

to hopefully try out referring to Gatsby's webpack config directly or through the dev middleware maybe?... but those didn't work

I tried a couple tips from ChatGPT, such as setting my gatsby-node.js to

const webpack = require('webpack');
const cypressWebpackPreprocessor = require('cypress-webpack-preprocessor');

module.exports = (on, config) => {
  // Add the webpack preprocessor
  on('file:preprocessor', cypressWebpackPreprocessor);

  // Modify the webpack configuration
  on('before:browser:launch', (browser, launchOptions) => {
    if (browser.name === 'chrome') {
      launchOptions.args.push('--auto-open-devtools-for-tabs');
      return launchOptions;
    }

    if (browser.name === 'firefox') {
      launchOptions.args.push('--devtools');
      return launchOptions;
    }
  });
};

and also adding cypress/plugin/index.js:

const cypressWebpackPreprocessor = require('cypress-webpack-preprocessor');

module.exports = (on, config) => {
  on('file:preprocessor', cypressWebpackPreprocessor());
};
