How to save file to specific directory

• Electron version: 1.3.4

• Operating system: Windows 8.1 I am using spectron to test my app. I am opening dialog in my app like this:

  ipc.on('open-directory-dialog', (event, arg) => {
  
  let returnValue = function(directory) {
  
  if (typeof directory !== 'string') {
  
    directory = directory[0]
  }
  event.returnValue = directory
    }
    let options = {
      properties: [
       'openDirectory'
     ]
   }
    if (process.platform !== 'darwin') {
       dialog.showOpenDialog(options, (directory) => {
         if (directory) {
           returnValue(directory)
        }
  })
  return
    }
  returnValue(dialog.showOpenDialog(BrowserWindow.fromWebContents(event.sender), options))
  

And I want to auto select directory in test. I am using preload to do that. But it will make my app crash.

//preload
if (process.env.RUNNING_IN_SPECTRON) {
      dialog.showOpenDialog = (opts, cb) => {
        if (opts.title === 'open-directory-dialog') {
          cb(['C:/Users/user/Desktop/']);
          }
       };
   }

Any ideas?

It isn’t the const that makes it work. The old code was trying to call undefined as a function and all sorts of other dodgy things.

This is just correct code 👍

Closing this out as the original question / issue has been resolved 👍

@disc9562 I have a PoC for adding electron-test-utils bindings to Spectron, but until that I’ll just fix your mocking function 👍

//preload
const paths = ['C:/Users/user/Desktop/'];

if (process.env.RUNNING_IN_SPECTRON) {
   dialog.showOpenDialog = (opts, cb) => {
     if (opts.title === 'open-directory-dialog') {
       if (cb) cb(paths);
       return paths;
     }
  };
}
