From v5 to v6

This tutorial is for people who are still using v5 of WebdriverIO and want to migrate to v6 or to the latest version of WebdriverIO. As mentioned in our release blog post the changes for this version upgrade can be summarised as following:

  • we consolidated the parameters for some commands (e.g. newWindow, react$, react$$, waitUntil, dragAndDrop, moveTo, waitForDisplayed, waitForEnabled, waitForExist) and moved all optional parameters into a single object, e.g.

    // v5
    'WebdriverIO window',
    // v6
    browser.newWindow('', {
    windowName: 'WebdriverIO window',
    windowFeature: 'width=420,height=230,resizable,scrollbars=yes,status=1'
  • configurations for services moved into the service list, e.g.

    // v5
    exports.config = {
    services: ['sauce'],
    sauceConnect: true,
    sauceConnectOpts: { foo: 'bar' },
    // v6
    exports.config = {
    services: [['sauce', {
    sauceConnect: true,
    sauceConnectOpts: { foo: 'bar' }
  • some service options were renamed for simplification purposes

  • we renamed command launchApp to launchChromeApp for Chrome WebDriver sessions


If you are using WebdriverIO v4 or below, please upgrade to v5 first.

While we would love to have a fully automated process for this the reality looks different. Everyone has a different setup. Every step should be seen as guidance and less like a step by step instruction. If you have issues with the migration, don't hesitate to contact us.


Similar to other migrations we can use the WebdriverIO codemod. To install the codemod, run:

npm install jscodeshift @wdio/codemod

Upgrade WebdriverIO Dependencies

Given that all WebdriverIO versions are tight to each other it is the best to always upgrade to a specific tag, e.g. 6.12.0. If you decide to upgrade from v5 directly to v7 you can leave out the tag and install latest versions of all packages. To do so we copy all WebdriverIO related dependencies out of our package.json and re-install them via:

npm i --save-dev @wdio/allure-reporter@6 @wdio/cli@6 @wdio/cucumber-framework@6 @wdio/local-runner@6 @wdio/spec-reporter@6 @wdio/sync@6 wdio-chromedriver-service@6 webdriverio@6

Usually WebdriverIO dependencies are part of the dev dependencies, depending on your project this can vary though. After this your package.json and package-lock.json should be updated. Note: these are example dependencies, yours may differ. Make sure you find the latest v6 version by calling, e.g.:

npm show webdriverio versions

Try to install the latest version 6 available for all core WebdriverIO packages. For community packages this can differ from package to package. Here we recommend to check the changelog for information on which version is still compatible with v6.

Transform Config File

A good first step is to start with the config file. All breaking changes can be resolve using the codemod full automatically:

npx jscodeshift -t ./node_modules/@wdio/codemod/v6 ./wdio.conf.js

The codemod doesn't yet support TypeScript projects. See @webdriverio/codemod#10. We are working to implement support for it soon. If you are using TypeScript please get involved!

Update Spec Files and Page Objects

In order to update all command changes run the codemod on all your e2e files that contain WebdriverIO commands, e.g.:

npx jscodeshift -t ./node_modules/@wdio/codemod/v6 ./e2e/*

That's it! No more changes necessary 🎉


We hope this tutorial guides you a little bit through the migration process to WebdriverIO v6. We strongly recommend to continue upgrading to the latest version given that updating to v7 is trivial due to almost no breaking changes. Please check out the migration guide to upgrade to v7.

The community continues to improve the codemod while testing it with various teams in various organisations. Don't hesitate to raise an issue if you have feedback or start a discussion if you struggle during the migration process.
