Behat ensure that select field has these options - behat

Question

With Behat how can I make sure that a select field contains a given set of options?
I can't see any core methods for checking this.

Answer 1

Add the following to your FeatureContext.php:
/**
* #Then /^the select field "([^"]*)" should have a list containing:$/
*
* #param $locator
* string $locator input id, name or label
* #param \Behat\Gherkin\Node\PyStringNode $list
* A list of options that should be present.
*/
public function shouldHaveAListContaining($locator, PyStringNode $list): void {
$session = $this->getSession();
$page = $session->getPage();
$element = $page->findField($locator);
if ($element === NULL) {
throw new \InvalidArgumentException(sprintf('Could find element "%s".', $locator));
}
$options = [];
foreach ($element->findAll('css', 'option') as $option) {
$options[] = $option->getText();
}
$missing = array_diff($list->getStrings(), $options);
if (count($missing) > 0) {
$context = [$locator, implode(', ', $missing)];
throw new \RuntimeException(vsprintf('Element "%s" is missing these options "%s"', $context));
}
}
And the call it like this:
And the select field "YOUR_LABEL" should have a list containing:
"""
Option 1
Option 2
"""
