I have found that sometimes the versions of the selenium-standalone have caused my tests to fail. So I would check if you have recently upgraded the selenium-standalone package or if you're starting the selenium server manually, any of the drivers or selenium server version (i.e. 3.4 to 3.5)

At the moment I use npm install -g [email protected] for my tests. This was the last version that still uses selenium 3.4.

@reubenmiller : I am using selenium-server-standalone-3.8.1.jar on my local machine and getting the same error and yes I am starting selenium server manually.

on my client server I am using selenium-server-standalone-3.6.0.jar and starting selenium server manually and getting this[error : unknown command: session/0560573d012ab858001aaea2ae11fcb0/window/rect] there also

Ok, I think this is a bug with the resizeWindow function in the WebDriverIO Helper in codeceptjs. I have done a test on my machine and it looks ok. Though can you quickly test it out on your machine to see if it solves your problem?

Steps

  1. Open the folllowing file in a text editor ./node_modules/codeceptjs/lib/helper/WebDriverIO.js
  2. Search for the function async resizeWindow
  3. Replace this function with the following code.
/**
   * {{> ../webapi/resizeWindow }}
   * Appium: not tested in web, in apps doesn't work
   */
  async resizeWindow(width, height) {
    if (width !== 'maximize') {
      return this.browser.windowHandleSize({ width, height });
    }

    const { screenWidth, screenHeight } = await this.browser.execute(() => ({
      screenHeight: window.screen.height,
      screenWidth: window.screen.width,
    })).then(res => res.value);

    return this.browser.windowHandleSize({ width: screenWidth, height: screenHeight });
  }
  1. Run your tests which was seeing this error.

Let me know if you have any luck. If it solves it then I will submit a PR.

@reubenmiller : I did this but I am getting the same error.I am just pasting below the webdriverIO file after edit that you ask me to do.

let webdriverio;
const requireg = require('requireg');
const Helper = require('../helper');
const stringIncludes = require('../assert/include').includes;
const { urlEquals, equals } = require('../assert/equal');
const empty = require('../assert/empty').empty;
const truth = require('../assert/truth').truth;
const {
xpathLocator, fileExists, clearString, decodeUrl, chunkArray,
} = require('../utils');
const ElementNotFound = require('./errors/ElementNotFound');
const assert = require('assert');
const path = require('path');

const webRoot = 'body';
const Locator = require('../locator');

let withinStore = {};

/**

  • WebDriverIO helper which wraps webdriverio library to
  • manipulate browser using Selenium WebDriver or PhantomJS.
    *
  • WebDriverIO requires Selenium Server and ChromeDriver/GeckoDriver to be installed.
    *
  • ### Configuration
    *
  • This helper should be configured in codecept.json
    *

    • url - base url of website to be tested


    • browser - browser in which perform testing


    • restart (optional, default: true) - restart browser between tests.


    • smartWait: (optional) enables SmartWait; wait for additional milliseconds for element to appear. Enable for 5 secs: "smartWait": 5000


    • disableScreenshots (optional, default: false) - don't save screenshot on failure


    • uniqueScreenshotNames (optional, default: false) - option to prevent screenshot override if you have scenarios with the same name in different suites


    • keepBrowserState (optional, default: false) - keep browser state between tests when restart set to false.


    • keepCookies (optional, default: false) - keep cookies between tests when restart set to false.


    • windowSize: (optional) default window size. Set to maximize or a dimension in the format 640x480.


    • waitForTimeout: (option) sets default wait time in ms for all wait* functions. 1000 by default;


    • desiredCapabilities: Selenium's [desired

  • capabilities](https://github.com/SeleniumHQ/selenium/wiki/DesiredCapabilities)

    • manualStart (optional, default: false) - do not start browser before a test, start it manually inside a helper

  • with this.helpers["WebDriverIO"]._startBrowser()
  • Example:
    *
  • ```json
  • {
  • "helpers": {
  • "WebDriverIO" : {
  • "smartWait": 5000,
  • "browser": "chrome",
  • "restart": false,
  • "windowSize": "maximize",
  • "timeouts": {
  • "script": 60000,
  • "page load": 10000
  • }
  • }
  • }
  • }
  • ```
    *
  • Additional configuration params can be used from [webdriverio
  • website](http://webdriver.io/guide/getstarted/configuration.html).
    *
  • ### Headless Chrome
    *
  • ```json
  • {
  • "helpers": {
  • "WebDriverIO" : {
  • "url": "http://localhost",
  • "browser": "chrome",
  • "desiredCapabilities": {
  • "chromeOptions": {
  • "args": [ "--headless", "--disable-gpu", "--window-size=800,600" ]
  • }
  • }
  • }
  • }
  • }
  • ```
    *
  • ### Connect through proxy
    *
  • CodeceptJS also provides flexible options when you want to execute tests to Selenium servers through proxy. You will
  • need to update the helpers.WebDriverIO.desiredCapabilities.proxy key.
    *
  • ```js
  • {
  • "helpers": {
  • "WebDriverIO": {
  • "desiredCapabilities": {
  • "proxy": {
  • "proxyType": "manual|pac",
  • "proxyAutoconfigUrl": "URL TO PAC FILE",
  • "httpProxy": "PROXY SERVER",
  • "sslProxy": "PROXY SERVER",
  • "ftpProxy": "PROXY SERVER",
  • "socksProxy": "PROXY SERVER",
  • "socksUsername": "USERNAME",
  • "socksPassword": "PASSWORD",
  • "noProxy": "BYPASS ADDRESSES"
  • }
  • }
  • }
  • }
  • }
  • ```
  • For example,
    *
  • ```js
  • {
  • "helpers": {
  • "WebDriverIO": {
  • "desiredCapabilities": {
  • "proxy": {
  • "proxyType": "manual",
  • "httpProxy": "http://corporate.proxy:8080",
  • "socksUsername": "codeceptjs",
  • "socksPassword": "secret",
  • "noProxy": "127.0.0.1,localhost"
  • }
  • }
  • }
  • }
  • }
  • ```
    *
  • Please refer to Selenium - Proxy Object for more
  • information.
    *
  • ### Cloud Providers
    *
  • WebDriverIO makes it possible to execute tests against services like Sauce Labs BrowserStack TestingBot
  • Check out their documentation on available parameters
    *
  • Connecting to BrowserStack and Sauce Labs is simple. All you need to do
  • is set the user and key parameters. WebDriverIO automatically know which
  • service provider to connect to.
    *
  • ```js
  • {
  • "helpers":{
  • "WebDriverIO": {
  • "url": "YOUR_DESIRED_HOST",
  • "user": "YOUR_BROWSERSTACK_USER",
  • "key": "YOUR_BROWSERSTACK_KEY",
  • "desiredCapabilities": {
  • "browserName": "chrome",
    *
  • // only set this if you're using BrowserStackLocal to test a local domain
  • // "browserstack.local": true,
    *
  • // set this option to tell browserstack to provide addition debugging info
  • // "browserstack.debug": true,
  • }
  • }
  • }
  • }
  • ```
    *
  • ### Multiremote Capabilities
    *
  • This is a work in progress but you can control two browsers at a time right out of the box.
  • Individual control is something that is planned for a later version.
    *
  • Here is the webdriverio docs on the subject
    *
  • ```js
  • {
  • "helpers": {
  • "WebDriverIO": {
  • "multiremote": {
  • "MyChrome": {
  • "desiredCapabilities": {
  • "browserName": "chrome"
  • }
  • },
  • "MyFirefox": {
  • "desiredCapabilities": {
  • "browserName": "firefox"
  • }
  • }
  • }
  • }
  • }
  • }
  • ```
    *
    *
  • ## Access From Helpers
    *
  • Receive a WebDriverIO client from a custom helper by accessing browser property:
    *
  • ```js
  • this.helpers['WebDriverIO'].browser
  • ```

You didn't replace the whole function definition.

And please use git gists instead of posting whole files here.

Use this WebDriverIO.js file and try again.

@reubenmiller : sorry to mess up the comments with large paste of file,I will use git gists from now.

I just replaced my WebdriverIO.js with the one you shared with me.

Still I am getting the same error and below is the error message.

I think this is something to do with your setup of your selenium standalone server (maybe something to do with your last comment in issue #878).

reubenmiller picture reubenmiller on 28 Jan 2018

@reubenmiller : I tried to Run java -jar -Dwebdriver.ie.driver=IEDriverServer.exe selenium-server-standalone-2.53.1.jar and then Run my tests ,again I am getting the same error.

So its sure that its not related to selenium server setup of mines as with same setup it was working earlier,but all of sudden from last 6-7 days its giving error.

ninpop25 picture ninpop25 on 28 Jan 2018

Ok, next try. I cloned my Codeceptjs-starter project and edited the ./node_modules/codeceptjs/lib/helper/WebDriverIO.js with the contents from my updated gist.

So can you try and debug it:

Debug option 1: Try a new version of WebDriverIO.js Helper

Replace the ./node_modules/codeceptjs/lib/helper/WebDriverIO.js file with contents from this updated gist.

Debug option 2: Try manually setting the windowSize resolution

Though if that does not work, can you just change the windowSize property in your config file to 1024x720? If specifying an exact size works then we have narrowed it down to the maximize logic. Otherwise it is something weird with your selenium server config.

Let me know the results

reubenmiller picture reubenmiller on 28 Jan 2018

@reubenmiller : I followed the Debug option 1,after that again it got failed for me...then I opt Debug option 2 and guess what again it got failed.

After that it just clicked in my mind to download the latest Chromedriver and this time it worked for me,so basically I was having old version of Chromedriver .

Strange thing is that on my client server I am using the latest ChromeDriver i.e. 2.33 and few days back I was got this error for 2 to 3 days continuously and since yesterday its not coming,so as off now changing the chromedriver worked for me on my local machine.

I will let you know if this fails on my server with this latest chromedriver again.

Thanks for this great help and Yes this change of WebdriverIO also worked I think :)
