Electron app opening multiple windows or processes in spectron test

#javascript #html #node #electron

My electron app works as expected but it keeps on opening new windows when I run spectron test that tests for number of windows opened.

Versions Installed
npm ls --depth=0 demoelectronapp@1.0.0 C:\demoCLS\demoElectronApp +-- assert@2.0.0 +-- electron@8.2.2 +-- electron-packager@14.2.1 +-- mocha@7.1.1 +-- path@0.12.7 `-- spectron@10.0.1

I am just running a small demo, below I will give code snippet

Note: I am running the spectron test pointing to .exe file generated by electron-packager.

Does Anyone have an idea what is the issue if possible how to solve it?

main.js
`
const { app, BrowserWindow } = require('electron')

function createWindow () {

let win = new BrowserWindow({
width: 800,
height: 600,
webPreferences: {
nodeIntegration: true
}
})

win.loadFile('index.html')
}

app.whenReady().then(createWindow)

` **index.js** `
<!DOCTYPE html>

Hello World!

`

**test.js**

`

const assert = require('assert');
const path = require('path');
const Application = require('spectron').Application;
const electronPath = require('electron');

const app = new Application({
path: 'C:/demoElectronApp/winx64/demoelectronapp-win32-x64/demoelectronapp.exe',
});

describe('client_settings_app', function () {
this.timeout(10000);

beforeEach(() => {
  return app.start();
});

it('shows only one initial window', async () => {
  const count = await app.client.getWindowCount();
  return assert.equal(count, 1);
});

})

Okay, I was having the same issue. And solved by setting remote debugging port.

chromeDriverArgs: ['remote-debugging-port=9222']:

Necessary codes:

env: {
ELECTRON_ENABLE_LOGGING: true,
ELECTRON_ENABLE_STACK_DUMPING: true,
NODE_ENV: 'test'
},
waitTimeout: 10e3,
requireName: 'electronRequire',
chromeDriverLogPath: '../chromedriverlog.txt',
chromeDriverArgs: ['remote-debugging-port=9222']
