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');
