This test will be finished in an hour. At least, this situation looks like a big problem for me and other people who don't know about that.

I found a temporary solution to solve my problem:
let hasAlert = function () {
try {
browser.getTitle();
catch (error) {
return error.seleniumStack.type === 'UnexpectedAlertOpen';
return false;
I just tested this against master, and it seems that 8b12008 has fixed this issue.
I tested all three functions (alertDismiss, alertAccept, alertText) on pages with alerts and pages without alerts. alertText (the problem function) was tested for both the jsonwire happy path (/session/:sessionId/alert_text), and the webdriver fallback path.
The current behaviour on master for all three functions (as mentioned in the previous paragraph): throw an exception with the exception.type of RuntimeError, and the exception.seleniumStack.type of NoAlertOpenError.
Based on that, I would say this could be closed... unless throwing errors is not expected behaviour. If it is expected behaviour @christian-bromann, comment so and I can add something to the docs around an exception being thrown if no alert was present.
