如何使用Behat/Mink从下拉列表中验证所选选项

我也有同样的问题,我想使用选项值和选择css选择器来确定所选选项的值。这就是我最后所做的:

/**
 * @Then /^the option "([^"]*)" from select "([^"]*)" is selected$/
 */
public function theOptionFromSelectIsSelected($optionValue, $select)
{
    $selectField = $this->getSession()->getPage()->find('css', $select);
    if (NULL === $selectField) {
        throw new \Exception(sprintf('The select "%s" was not found in the page %s', $select, $this->getSession()->getCurrentUrl()));
    }

    $optionField = $selectField->find('xpath', "//option[@selected='selected']");
    if (NULL === $optionField) {
        throw new \Exception(sprintf('No option is selected in the %s select in the page %s', $select, $this->getSession()->getCurrentUrl()));
    }

    if ($optionField->getValue() !== $optionValue) {
        throw new \Exception(sprintf('The option "%s" was not selected in the page %s, %s was selected', $optionValue, $this->getSession()->getCurrentUrl(), $optionField->getValue()));
    }
}

如果您不想在功能上下文中添加自定义步骤,可以尝试直接在Gherkin中使用CSS选择器:

Then the "select[name='day'] option[selected='selected']" element should contain "Thursday"

And the "select[name='month'] option[selected='selected']" element should contain "April"

我用这个步骤定义了一个上下文:

/**
 * Checks, that option from select with specified id|name|label|value is selected.
 *
 * @Then /^the "(?P<option>(?:[^"]|\\")*)" option from "(?P<select>(?:[^"]|\\")*)" (?:is|should be) selected/
 * @Then /^the option "(?P<option>(?:[^"]|\\")*)" from "(?P<select>(?:[^"]|\\")*)" (?:is|should be) selected$/
 * @Then /^"(?P<option>(?:[^"]|\\")*)" from "(?P<select>(?:[^"]|\\")*)" (?:is|should be) selected$/
 */
public function theOptionFromShouldBeSelected($option, $select)
{
    $selectField = $this->getSession()->getPage()->findField($select);
    if (null === $selectField) {
        throw new ElementNotFoundException($this->getSession(), 'select field', 'id|name|label|value', $select);
    }

    $optionField = $selectField->find('named', array(
        'option',
        $option,
    ));

    if (null === $optionField) {
        throw new ElementNotFoundException($this->getSession(), 'select option field', 'id|name|label|value', $option);
    }

    if (!$optionField->isSelected()) {
        throw new ExpectationException('Select option field with value|text "'.$option.'" is not selected in the select "'.$select.'"', $this->getSession()); 
    }
}

因此,您可以在Behat功能中添加以下步骤:

Then the "Option 1" option from "Select options" should be selected

您可以在这里看到完整的上下文代码: https://github.com/Aplyca/BehatContexts/blob/master/src/Aplyca/BehatContext/FormContext.php#L64

如果要声明如下所示的选择值:

And "4" from "Number of Columns" is selected
And "red" from "Background Color" is selected
And "plaid" from "Background Image" is selected

然后使用@Dallas的这个修改/改进版本

  /**
   * @Then /^"([^"]*)" from "([^"]*)" is selected$/
   *
   * To assert a select value.

   */
  public function theOptionFromSelectIsSelected($optionValue, $select) {
    $selectField = $this->getSession()->getPage()->findField($select);

    if (NULL === $selectField) {
      throw new \Exception(sprintf('The select "%s" was not found in the page %s', $select, $this->getSession()->getCurrentUrl()));
    }

    $optionField = $selectField->find('xpath', "//option[@selected]");
    if (NULL === $optionField) {
      throw new \Exception(sprintf('No option is selected in the %s select in the page %s', $select, $this->getSession()->getCurrentUrl()));
  }

  if ($optionField->getValue() != $optionValue) {
    throw new \Exception(sprintf('The option "%s" was not selected in the page %s, %s was selected', $optionValue, $this->getSession()->getCurrentUrl(), $optionField->getValue()));
  }
}

我使用以下代码获取所选选项的值

$elementByName = $this->getSession ()->getPage ()->find ( 'css', "#" . $name );

if (! $elementByName) {
    throw new FailureException ( 'select with name ' . $name . ' is not found' );
} else {
    $v = $elementByName->getValue ();
}

以下选择器适用于我:

$defaultFilterDay = $page->find("css", "#day option[selected='selected']")->getText();
    $defaultFilterMonth = $page->find("css", "#month option[selected='selected']")->getText();

    date_default_timezone_set('UTC');
    $currentTime = new \DateTime('now');
    $currentDay = $currentTime->format('l');
    $currentMonth = $currentTime->format('F');

    assertEquals($currentDay, $defaultFilterDay);
    assertEquals($currentMonth, $defaultFilterMonth);
