如何在 python 中使用 selenium webdriver 将内容设置为 mui-rte？

Question

我在 react 项目中使用 mui-rte 富文本编辑器 (https://github.com/niuware/mui-rte)。在编写 selenium webdriver 集成测试时，我无法弄清楚如何将文本输入到 rte 输入区域。

据我了解，mui-rte 是 Draftjs 的 materia-ui 包装器。反应代码很简单：

<MUIRichTextEditor
        onChange={onChange}
        value={initial}
        {...rest}
/ >

这会生成以下 html 元素：

<div id="mui-rte-container" class="MUIRichTextEditor-container-73">
<div id="mui-rte-toolbar" class="MUIRichTextEditor-toolbar-84">
    ...
</div>
<div id="mui-rte-editor" class="MUIRichTextEditor-editor-75">
    <div id="mui-rte-editor-container" class="MUIRichTextEditor-hidePlaceholder-79 MUIRichTextEditor-editorContainer-76">
        <div class="DraftEditor-root">
            <div class="DraftEditor-editorContainer">
                <div aria-describedby="placeholder-9mnek" class="notranslate public-DraftEditor-content" role="textbox" spellcheck="false" style="outline:none;user-select:text;-webkit-user-select:text;white-space:pre-wrap;word-wrap:break-word" contenteditable="true">
                    <div data-contents="true"><div class="" data-block="true" data-editor="7kjuh" data-offset-key="8a2rc-0-0">
                        <div data-offset-key="8a2rc-0-0" class="public-DraftStyleDefault-block public-DraftStyleDefault-ltr">
                            <span data-offset-key="8a2rc-0-0">
                                <br data-text="true">
                            </span>
                        </div>
                    </div>
                    </div>
                </div>
            </div>
        </div>
    </div>
</div>

我可以很容易地找到任何元素，但是当我尝试这个时：

from selenium import webdriver
from selenium.webdriver.support.ui import WebDriverWait # available since 2.4.0
from selenium.webdriver.support import expected_conditions as EC # available since 2.26.0
from selenium.webdriver.common.by import By

rte_editor = WebDriverWait(self.driver, 2).until(
        EC.presence_of_element_located((By.ID, id))
    )
rte_input = bio_rte.find_element_by_xpath("//div[@role='textbox']")
rte_input.send_keys("Hello")

我明白了：

E       selenium.common.exceptions.ElementNotInteractableException: Message: Element <div class="notranslate public-DraftEditor-content"> is not reachable by keyboard

我尝试过的所有元素。

在python中使用selenium-webdriver将文本输入draft.js rte的正确方法是什么？我对 selenium+webdriver 很陌生，任何帮助都将不胜感激，无论是 python、JavaScript 还是其他风格的 selenium-webdriver API。

Answer 1

在我的例子中，它是一个带有 contenteditable div

的 draft.js 富文本编辑器

async sendKeysToContentEditableDiv(element, text) {
    const script = `var txtarea = arguments[0],txt = arguments[1];
    txtarea.dispatchEvent(new Event("focus"));
    var txtEvt = document.createEvent("TextEvent");
    txtEvt.initTextEvent("textInput", true, true, null, txt);
    txtarea.dispatchEvent(txtEvt);     
    txtarea.dispatchEvent(new Event("blur"));`;
    await this.driver.executeScript(script, element, text);
}

所需元素是启用了ReactJS 的元素，以便定位并发送字符序列 到您必须为element_to_be_clickable() 诱导WebDriverWait 的元素，然后您可以使用以下任一解决方案：

• 使用CSS_SELECTOR：

  WebDriverWait(driver, 20).until(EC.element_to_be_clickable((By.CSS_SELECTOR, "div.notranslate.public-DraftEditor-content[role='textbox']"))).send_keys("Vess_Perfanov")
  

• 使用XPATH：

  WebDriverWait(driver, 20).until(EC.element_to_be_clickable((By.XPATH, "//div[@class='notranslate public-DraftEditor-content' and @role='textbox']"))).send_keys("Vess_Perfanov")
  

• 注意：您必须添加以下导入：

  from selenium.webdriver.support.ui import WebDriverWait
  from selenium.webdriver.common.by import By
  from selenium.webdriver.support import expected_conditions as EC
  

---

更新

由于click() 仍未被WebDriverWait 调用，您可以按如下方式使用ActionChains：

• 使用CSS_SELECTOR:

  element = WebDriverWait(driver, 20).until(EC.element_to_be_clickable((By.CSS_SELECTOR, "div.notranslate.public-DraftEditor-content[role='textbox']"))).send_keys("Vess_Perfanov")
  ActionChains(driver).move_to_element(element).click(element).send_keys("Vess_Perfanov").perform()
  

• 使用XPATH：

  element = WebDriverWait(driver, 20).until(EC.element_to_be_clickable((By.XPATH, "//div[@class='notranslate public-DraftEditor-content' and @role='textbox']"))).send_keys("Vess_Perfanov")
  ActionChains(driver).move_to_element(element).click(element).send_keys_to_element(element, "Vess_Perfanov").perform()

Material-UI 中有一个内联标签元素，需要先单击它才能发现底层文本字段。所以以下对我有用。

from selenium import webdriver
from selenium.common.exceptions import TimeoutException
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC
from selenium.webdriver.common.by import By
from selenium.webdriver import ActionChains
import unittest


class TestBase(unittest.TestCase):

def setUp(self):
    self.driver = webdriver.Firefox()
    self.driver.get(URL)

def tearDown(self):
    self.driver.close()

def get_by_id(self, id):
    return WebDriverWait(self.driver, 5).until(
        EC.presence_of_element_located((By.ID, id))
    )
def test_input_text_in_rte(self):
    description_msg = "Hello There"
    rte_container = self.get_by_id('mui-rte-container')
    rte_label = rte_container.find_element_by_xpath("//*[contains(text(), 'Description:')]")
    actions = ActionChains(self.driver)
    actions.move_to_element(rte_label)
    actions.click(rte_label)
    actions.perform()

    rte_input = WebDriverWait(self.driver, 5).until(
        EC.presence_of_element_located((By.XPATH,
            '//div[@class="notranslate public-DraftEditor-content" and @role="textbox"]'))
    )

    rte_input.send_keys(description_msg)
