Test <select> Elements

This recipe shows how to test <select> elements and pick options from the drop-down list.

Assume the following <select> element.

<select id="city">
    <option>New York</option>
    <option>London</option>
    <option>Paris</option>
</select>

This is a simple drop-down list that contains three values for New York, London and Paris.

In this recipe, you will learn how to create a test that selects a value from this list and checks that the <select> element contains the right city.

Here is the full test code and further we will reproduce it step by step.

import { Selector } from 'testcafe';

fixture `Test select element`
    .page `http://localhost:8080`;

const citySelect = Selector('#city');
const cityOption = citySelect.find('option');

test(`Select an option from the drop-down menu`, async t => {
    await t
        .click(citySelect)
        .click(cityOption.withText('London'))
        .expect(citySelect.value).eql('London');
});

Begin with an empty test.

import { Selector } from 'testcafe';

fixture `Test select element`
    .page `http://localhost:8080`;

test(`Select an option from the drop-down menu`, async t => {
    // Here you will put test code.
});

First, you need a selector that picks the <select> element.

const citySelect = Selector('#city');

Use this selector to click the element and invoke the drop-down menu.

await t.click(citySelect);

Next, write code that selects London from the drop-down list. To this end, introduce a selector that identifies options. This selector uses the find function to locate <option> elements inside <select>.

const cityOption = citySelect.find('option');

To find the London value, use the selector's filter methods that include withText, nth and withAttribute. Then pass this selector to the click method.

await t
    .click(citySelect)
    .click(cityOption.withText('London'));

Finally, add an assertion that checks that the <select> element has the London value selected.

await t
    .click(citySelect)
    .click(cityOption.withText('London'))
    .expect(citySelect.value).eql('London');
