Flow of Execution

  1. Test script sends a command (e.g., click()) via WebDriver API.
  2. WebDriver API forwards the command to the browser-specific driver.
  3. The driver communicates with the browser using HTTP.
  4. The browser acts and sends the response back.

The driver returns the result to the test script.
