Your test code has direct access to the DOM and not an indirect one via CDP or WebDriver, so the test and application code are one.Īs it happens, that’s the same approach that Selenium took before it merged with WebDriver. There is no layer between the tests and the browser anymore.
The tests themselves don’t use CDP at all but run directly in the browser. In which category does Cypress fall? Cypress relies on CDP but, in contrast to Puppeteer, Cypress only uses CDP to manage the tests. WebdriverIO is a hybrid framework it provides both access to CDP and WebDriver. It uses CDP as well but also supports Safari because it ships with patched browsers. So, one could see Playwright as a rewrite of Puppeteer. Some of Puppeteer’s original developers are behind Playwright. Although Firefox supports CDP as well, the kind of cross-browser testing WebDriver enables is not possible. This gives them much better control, which leads to more stable tests.ĬDP binds to Chromium-based browsers including Chrome and Edge. They don’t rely on WebDriver but talk directly to the browser via the Chrome DevTools Protocol (CDP). Two quite popular alternatives are Puppeteer and Playwright. You spend a considerable amount of time building tests that should guarantee the stability of the application and then you can’t even trust the tests’ results. That is extremely bad for a testing framework. If you run the tests multiple times under the same circumstances, they may fail or they may succeed. Unfortunately, WebDriver-based tests have a flaky reputation. Over time, WebDriver, the core technology in Selenium, became a W3C standard, which opened doors for other vendors to create their own frameworks based on WebDriver. This means that you can run the same test on Safari, Chrome, mobile browsers, etc.
#PROTRACTOR FRAMEWORK DRIVER#
Every supported browser provides a driver which WebDriver uses to make these frameworks cross-browser capable. With Selenium/WebDriver, developers have a common API to automate a browser. Selenium is still a major player and Protractor is, more or less, a wrapper around it. It merged with a similar tool called WebDriver.
We can roughly split the available tools into two groups: those based on WebDriver and those that operate on the Chrome DevTools Protocol (CDP). The Landscape of E2E Testing Frameworks WebDriver-Based
