Playwright, being a tool primarily designed for browser automation, does not inherently include assertion methods like traditional testing frameworks. Assertions are usually part of the testing frameworks that you use in combination with Playwright.

When using Playwright with a testing framework such as Jest, Mocha, or Jasmine, you typically use the assertion methods provided by those frameworks. Here are some commonly used assertion methods from Jest framework:

  • expect(value).toBeFalsy()

27. What is the command used to scroll down to a web element?

await page.locator('your-selector').scrollIntoView();

28. What is the command to drag and drop?

await page.locator('your-selector').getAttribute("value");
