Here’s an example of aforloop that counts from 1 to 10, stepping one digit at a time. At each iteration, the script inserts some text and begins a new line. The JavaScript you wish to repeat is enclosed in braces ({ }) following theforstatement; this forms theforstatement block. Yo...
Otherwise, it throws a custom alert as written in the else statement in the script. Since we have simulated an alert in the script, we need to use the accept method in Selenium to resolve it. See the demonstration below. The last step is to end the test and quit the driver instance....
Now, the overall statement says:Get a reference to our selected answer element OR, if that doesn’t exist, use an empty object. Get the value of whatever was in the first statement.As a result, the value will either be the user’s answer or undefined, which means a user can skip a...
