Error message "The process is not defined during the Cypress in Angular with Cucumber process."

Exploring Cypress for end-to-end testing in an Angular 12 project with Cucumber and TypeScript has been quite the journey.

Cypress launches successfully using npx cypress open, displaying the feature file I've created: https://i.sstatic.net/Q5ld8.png

However, upon initiating the test for this feature, an error pops up as seen here: https://i.sstatic.net/Y8LT9.png

An attempt to address this issue led me to a similar problem described here. Unfortunately, no solution seemed applicable. The root cause seems to be the utilization of Cypress's browser causing the process variable to become inaccessible. While digging into this repository, no resolution was found either.

The project's package.json is structured like so:

{   "name": "randomAppName",   "version": "0.0.0", ... (package.json contents truncated)

The webpack.config.js includes the following configuration:

module.exports = {
  resolve: { ... (webpack config details truncated)

I am willing to provide any additional information if required. Your input on resolving this matter would be greatly appreciated.

Answer №1

process is undefined due to the code being executed in a browser environment in your particular scenario.

It seems that you may have utilized a configuration that was compatible with webpack 4, which included mock APIs for path (having a fallback) or for process specifically. Webpack 5 Release Notes: node.process removed

Apparently, the cucumber parser is running within the context of the browser using this loader by sending out the cucumber code to the browser bundle.

If there isn't a specific need, I would suggest avoiding the use of webpack altogether. With recent versions of Cypress, transpiling TypeScript may not be necessary. Instead, consider following the recommended setup outlined in the cypress-cucumber-preprocessor readme:

If webpack is necessary, an option could be to simulate the process variable. I have confirmed that appending the following code snippet to support/index.js functions properly when utilizing webpack 5 with the initial example repository:

window.process = {
 argv: [],
 env: {},
};
