Selenium处理select标签的下拉框

Selenium是一个开源的和便携式的自动化软件测试工具,用于测试Web应用程序有能力在不同的浏览器和操作系统运行。Selenium真的不是一个单一的工具,而是一套工具,帮助测试者更有效地基于Web的应用程序的自动化。

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。

<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-selenium中的操作  

 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() 方法符合我们的要求,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-selenium中的操作

  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

}

}
