Answer 1

The configuration option "trashAssetsBeforeRuns": true is by default true, so unless you have already changed it, that's not the answer you're looking for.

Please be aware that it only applies to cypress run (headless) mode, ref cypress.d.ts (confirmed with a simple test).

Also be aware of the downloadsFolder configuration option which defaults to /cypress/downloads. Outside the project, use the full path.

---

For cypress open the recipe local-download-spec.js gives you an example.

Test

import { deleteDownloadsFolder } from './utils'
...
beforeEach(deleteDownloadsFolder)
...

Utils

export const deleteDownloadsFolder = () => {
  const downloadsFolder = Cypress.config('downloadsFolder')
  cy.task('deleteFolder', downloadsFolder)
}

Task in /cypress/plugins/index.js

const { rmdir } = require('fs')

module.exports = (on, config) => {
  on('task', {
    deleteFolder(folderName) {
      console.log('deleting folder %s', folderName)

      return new Promise((resolve, reject) => {
        rmdir(folderName, { maxRetries: 10, recursive: true }, (err) => {
          if (err) {
            console.error(err)
            return reject(err)
          }
          resolve(null)
        })
      })
    },
  })
}

I tried this code and it worked perfectly for me the first time. However I needed to also implement a check for the folder becuase if the folder does not exist this code will fail. – Renaissance

You can add this configuration to cypress.json: "trashAssetsBeforeRuns": true

Answer 3

The quickest solution is to use cypress-delete-downloads-folder npm package. Just several lines added to your Cypress configuration files would allow cleaning the folder from your tests with one command:

cy.deleteDownloadsFolder()

@Rosen Mihaylov here's correct example, you just missed a few brackets and lines

Task in /cypress/plugins/index.js

    /// <reference types="cypress" />
    /* eslint-disable no-console */
    
    const { rmdir } = require('fs')
    
    
    /**
     * @type {Cypress.PluginConfig}
     */
    module.exports = (on, config) => {
        // `on` is used to hook into various events Cypress emits
        // `config` is the resolved Cypress config
    
        // register utility tasks to read and parse Excel files
        on('task', {
            deleteFolder(folderName) {
                console.log('deleting folder %s', folderName)
    
                return new Promise((resolve, reject) => {
                    rmdir(folderName, { maxRetries: 10, recursive: true }, (err) => {
                        if (err) {
                            console.error(err)
    
                            return reject(err)
                        }
    
                        resolve(null)
                    })
                })
            },
        })
    }

Year, it is. But I'm saying here was a few mistakes with missing brackets and line, such as: javascript on('task', { – Mccown

Answer 5

you can try with cy.exce() Example cy.exec("find . -name " + <downloadDirectory> + "file"); cy.exec("cd " + <downloadDirectory> + ' ' + "&& rm -rf *");

Add this in your config.js

on('task', {
  deleteFolder(folderName) {
    return new Promise((resolve, reject) => {
      rm(
        folderName,
        {
          maxRetries: 10,
          recursive: true
        },
        (err) => {
          if (err) {
            console.error(err)
          }
          resolve(null)
        }
      )
    })
  }
})

And then add this in your test:

beforeEach(() => {
  cy.task('deleteFolder', 'cypress//downloads//');
});

If specifically want to delete a file you can add filename after cypress//downloads//filename
