问题 Can we catch in Selenium WebDriver events generated by the user (or events in general)? I know we can check state of page f.e. with WebDriverWait and ExpectedConditions, but that is not always appropriate. Let's say I wanted to wait for user input to continue execution of test class. It would look something like this: driver.get("https://www.google.com"); waitForKey(driver, org.openqa.selenium.Keys.RETURN); /* rest of code */ driver.quit(); Where waitForKey would be implemented as: public

Could it handle the user simply pressing the enter key w/o a command, junk input, etc? If anything, I would love to
