How to select any random value from a dropdown?

问题

I am working on selenium using Java. In my application I want to select any random value from the dropdown. Please tell how is it possible?

回答1:

Well, first get the total number of items in the dropdown. Then generate a random number between 0 and dropdown items count. Then select that number as index to set your dropdown item

回答2:

Use getSelectOptions to get an array of options of the select box.

Then generate a random integer between 0 (inclusive) and the length of the array (exclusive).

Then use select with an index locator to select the randomly chosen option.

What Sachin said. I know often it's good to get an actual code reply, so assuming you're working with a JComboBox:

comboBox.setSelectedIndex(new Random().nextInt(comboBox.getItemCount()));

The class Random can be found in the java.util package.

回答4:

First generate a random number between 0 and the number of items in your list. For example:

int random = new Random().nextInt(5);

Then use this random number as the index in your select call:

select("mydropdown", "index=" + random);
