One of the approaches to solve captchas, like Google ReCaptcha, is to try to imitate the human-mouse actions: movements, hovering and clicks.
Some users reported that making the mouse moves as B-spline curves worked for them.
How to move the mouse to a particular element following the B-spline trajectory via Selenium?
Note that the regular browser.actions().mouseMove(elm).perform(); would "jump" to the element straight and far too quickly. My understanding is that it is a matter of slowing down the movement speed, "jumping" from point to point smoothly following the mathematical model for the B-spline trajectory.
