selenium处理select标签的下拉框-自动化测试

更新时间:2022-03-29 09:29:01 作者:多测师 浏览:87

  有时候我们会碰到<select></select>标签的下拉框。直接点击下拉框中的选项不一定可行。Selenium专门提供了Select类来处理下拉框。

selenium处理select标签的下拉框-自动化测试

  <select id="status" class="form-control valid" onchange="" name="status">

  <option value=""></option>

  <option value="0">未审核</option>

  <option value="1">初审通过</option>

  <option value="2">复审通过</option>

  <option value="3">审核不通过</option>

   </select>

  Python

  先以python为例,查看Selenium代码select.py文件的实现:

  ...\selenium\webdriver\support\select.py

  class Select:

  def __init__(self, webelement):

  """

  Constructor. A check is made that the given element is, indeed, a SELECT tag. If it is not,

  then an UnexpectedTagNameException is thrown.

  :Args:

  - webelement - element SELECT element to wrap

  Example:

  from selenium.webdriver.support.ui import Select \n

  Select(driver.find_element_by_tag_name("select")).select_by_index(2)

  """

  if webelement.tag_name.lower() != "select":

  raise UnexpectedTagNameException(

  "Select only works on <select> elements, not on <%s>" %

  webelement.tag_name)

  self._el = webelement

  multi = self._el.get_attribute("multiple")

  self.is_multiple = multi and multi != "false"

  查看Select类的实现需要一个元素的定位。并且Example中给了例句。

  Select(driver.find_element_by_tag_name("select")).select_by_index(2)

  def select_by_index(self, index):

  """Select the option at the given index. This is done by examing the "index" attribute of an

  element, and not merely by counting.

  :Args:

  - index - The option at this index will be selected

  """

  match = str(index)

  matched = False

  for opt in self.options:

  if opt.get_attribute("index") == match:

  self._setSelected(opt)

  if not self.is_multiple:

  return

  matched = True

  if not matched:

  raise NoSuchElementException("Could not locate element with index %d" % index)

  继续查看select_by_index() 方法的使用并符合上面的给出的下拉框的要求,因为它要求下拉框的选项必须要有index属性,例如index=”1”。

  def select_by_value(self, value):

  """Select all options that have a value matching the argument. That is, when given "foo" this

  would select an option like:

  <option value="foo">Bar</option>

  :Args:

  - value - The value to match against

  """

  css = "option[value =%s]" % self._escapeString(value)

  opts = self._el.find_elements(By.CSS_SELECTOR, css)

  matched = False

  for opt in opts:

  self._setSelected(opt)

  if not self.is_multiple:

  return

  matched = True

  if not matched:

  raise NoSuchElementException("Cannot locate option with value: %s" % value)

  继续查看select_by_value() 方法符合我们的需求,它用于选取<option>标签的value值。最终,可以通过下面有实现选择下拉框的选项。

  from selenium.webdriver.support.select import Select

  ……

  sel = driver.find_element_by_xpath("//select[@id='status']")

  Select(sel).select_by_value('0')  #未审核

  Select(sel).select_by_value('1')  #初审通过

  Select(sel).select_by_value('2')  #复审通过

  Select(sel).select_by_value('3')  #审核不通过

  Java

  当然,在java中的用法也类似,唯一不区别在语法层面有。

  package com.jase.base;

  import org.openqa.selenium.WebDriver;

  import org.openqa.selenium.By.ById;

  import org.openqa.selenium.chrome.ChromeDriver;

  import org.openqa.selenium.support.ui.Select;

  public class SelectTest {

  public static void main(String[] args){

  WebDriver driver = new  ChromeDriver();

  driver.get("http://www.you_url.com");

  // ……

  Select sel = new Select(driver.findElement(ById.xpath("//select[@id='status']")));

  sel.selectByValue("0"); //未审核

  sel.selectByValue("1"); //初审通过

  sel.selectByValue("2"); //复审通过

  sel.selectByValue("3"); //审核不通过

  }

  }
