externalCssClasses

Uses the actor's ability to BrowseTheWeb to retrieve a list of CSS classes of a given PageElement.

Example widget

<ul id="shopping-list" class="active favourite">
<li class="bought">Coffee<li>
<li class="buy">Honey<li>
<li class="buy">Chocolate<li>
</ul>

Retrieve CSS classes of a given PageElement

import { actorCalled } from '@serenity-js/core'
import { Ensure, equals } from '@serenity-js/assertions'
import { By, CssClasses, PageElement } from '@serenity-js/web'

const shoppingList = () =>
PageElement.located(By.css('#shopping-list'))
.describedAs('shopping list')

await actorCalled('Lisa')
.attemptsTo(
Ensure.that(
CssClasses.of(shoppingList()),
equals([ 'active', 'favourite' ])
),
)

Using CssClasses as QuestionAdapter

import { actorCalled } from '@serenity-js/core'
import { Ensure, equals } from '@serenity-js/assertions'
import { By, CssClasses, PageElement } from '@serenity-js/web'

const shoppingList = () =>
PageElement.located(By.css('#shopping-list'))
.describedAs('shopping list')

await actorCalled('Lisa')
.attemptsTo(
Ensure.that(
CssClasses.of(shoppingList()).length,
equals(2)
),
Ensure.that(
CssClasses.of(shoppingList())[0],
equals('active')
),
)

Using as filter in Page Element Query Language

import { actorCalled } from '@serenity-js/core'
import { Ensure, contain } from '@serenity-js/assertions'
import { By, CssClasses, PageElement } from '@serenity-js/web'

class ShoppingList {
static items = () =>
PageElements.located(By.css('#shopping-list li'))
.describedAs('items')

static outstandingItems = () =>
ShoppingList.items()
.where(CssClasses, contain('buy'))
}

await actorCalled('Lisa')
.attemptsTo(
Ensure.that(
Text.ofAll(ShoppingList.outstandingItems()),
equals([ 'Honey', 'Chocolate' ])
