With v6 we have changed the structure of a couple of commands to allow named parameters instead. With that the code becomes much more readable and allows better type enforcement when using TypeScript. The above example looks in v6 as follows: We have changed the structure of the following commands: If you use TypeScript in your project it should automatically tell you to all places that needs to be updated. If you use the WebdriverIO API the experience using WebDriver vs Puppeteer should be the same, running commands on Puppeteer might even be a little faster. It also doesn't come with ready-to-go utils for third-party services like Sauce Labs or test reporters. Puppeteer also takes care of downloading Chrome for you and is generally easier to set up than Selenium for the development flow. If you are using the @wdio/appium-service you don't need to do anything. * and replace the WebdriverIO logo in the docs with the Puppeteer logo Playwright vs Puppeteer The second surprise was the lower overall variability shown in the WebDriverIO runs.

Members of the WebdriverIO project are part of the W3C Working Group that defines the WebDriver specification and they work together with browser vendors on solutions to improve the current state of the art. Also interesting is just how close the results are: the chart shows the lines crossing each other continuously, as the automation protocol does not seem to make a sizeable difference in execution time in this scenario. Note: using Puppeteer instead of WebDriver is only supported if running tests locally and if the browser is … Your test code will look simple, concise and easy to read. With the release of v6 we will continue to support v5 until we decide to release a new major version v7. They solve the problem of testing in their own way. Until v5 of WebdriverIO specific options to services and reporters could be defined anywhere in the wdio.conf.js, e.g. Most test automation frameworks are based on a common set of agile testing practices. Because of the great success of automation tools like Puppeteer and Cypress.io it became obvious that the WebDriver protocol in its current shape and form doesn't meet the requirements of todays developer and automation engineers. This blog post will go into details about all major changes and will explain what you need to do to transition from v5 to the v6.

WebdriverIO will only fallback to Puppeteer if it can't find a browser driver running. Cypress.io, WebDriver, Puppeteer, TestCafe — they are all great. All these additional plugins require specific configurations in your wdio.conf.js and we want to make sure that all these settings are being made standardised structure. It should be a pretty mechanical and straightforward task. WebDriver is a remote control interface that enables introspection and control of user agents. When our team was losing engineering hours to Selenium-related test flakiness, we switched to Puppeteer for some of our UI tests. Puppeteer affords more control over Chrome's browsers than Selenium WebDriver offers (likely due to Google’s support and sophisticated knowledge of Chrome). This major update is much more reasonable and contains subtle changes that will help the project further grow while remaining performant at the same time.
