For debugging selectors, see here. Is it possible to get the selector from a locator object in playwright? I'm storing page elements as locators in the Page Object Model, and you seemingly cannot access the selector of a locator, meaning the selector is duplicated in the code; I believe page.waitForSelector will use an ElementHandle which is discouraged; Is there any way to turn off the strictness constraint on a Locator? That way, you can make your Selenium tests part of your overall test suite and have your CI tool run them on each build or however often you prefer. Waits for the given timeout in milliseconds.

You should see something like this: Now youre all set up and ready to start writing your tests. Note that this property can be of a primitive type as well as a plain serializable JavaScript object.

The navigation must have been committed when this method is called. playwright.inspect(selector) Reveal element in the Elements panel (if DevTools of the respective browser supports it). The use of ElementHandle is discouraged, use Locator objects instead. During open or codegen, you can use following API inside the developer tools console of any browser.

The method returns an element locator that can be used to perform actions on this page / frame. You can either pass this timeout or configure it once via the testConfig.expect value in test config. One of Seleniums most known limitations is that its tests are often frail, breaking due to minimal application changes. Navigation starts by changing the page URL or by interacting with the page (e.g., clicking a link). ; target A selector to search for an element to drop onto. page.getByTestId(testId) to locate an element based on If no elements match the selector, returns empty array. Then, access that folder by the command line and run HTTP-server. The Playwright inspector is a great tool to help with debugging. Adds a
