I've been using Vaadin 8 for years, but a few months ago it was decided to use "Selenium" instead of Vaadin "Testbench". I will list some problems I have, maybe someone has a solution. I found a good explanatory page https://alexsiminiuc.medium.com/your-selenium-tests-are-not-slow-because-of-the-selenium-framework-63f871e2d38f but maybe someone has other information about this issue.
Expenditure:
Loading the first page, for example login page, takes more than 15 seconds to load in the browser and "noHeadlessMode". I think it's because of the Sass compiler that generates new data every time the user calls.
Sometimes "Selenium" waits even though no waiting time is defined. The wait time for WebDriver to avoid "NotFoundException" is set to 60 seconds and pause is not set. Maybe because "selenium" loads some code and does some checks that take some time?
Sometimes it just fails and can't find item even though it runs normally and there is item. Maybe a bug or an internal delay in "Selenium"?
Thanks for the help!
