机器人框架/Selenium 脚本无法在 Salesforce 页面上执行 Javascript

Question

我正在使用 Robot Framework 和 Selenium 对 Salesforce 应用程序进行自动化测试。我编写了一个测试用例脚本来登录 Salesforce、导航到“机会”页面并执行 JavaScript 代码片段以与页面上的元素进行交互。但是，我在执行脚本期间遇到错误。这是我的脚本的简化版本：

*** Settings ***
Library    SeleniumLibrary
Library    Dialogs
Library    Telnet

*** Variables ***
${URL}        https://mycompany.lightning.force.com/lightning/page/home
${BROWSER}    Chrome
${USERNAME}   ****
${PASSWORD}   ****                 
${element}    xpath://a[@title='Opportunities']
${chrome_options}    add_argument("--incognito")

*** Test Cases ***
Open Salesforce Login Page
    ${chrome_options}    Evaluate    sys.modules['selenium.webdriver'].ChromeOptions()    sys, selenium.webdriver
    Call Method    ${chrome_options}    add_argument    --incognito
    Open Browser    ${URL}    ${BROWSER}    options=${chrome_options}
    Title Should Be    Login | Salesforce
    Wait Until Page Contains    Username
    Input Text    id:username    ${USERNAME}
    Input Text    id:password    ${PASSWORD}
    Click Button    id:Login
    Wait Until Page Contains    Opportunities

Opportunity Creation
    Wait Until Page Contains Element   xpath://a[@title='Opportunities']   timeout=10s
    Execute Javascript    document.querySelector("a[title='Opportunities']").click();

当我运行此脚本时，它在执行 Javascript 步骤失败，并出现以下错误：

Opportunity Creation                                                  | FAIL |
JavascriptException: Message: javascript error: Cannot read properties of null (reading 'click')

我已经验证了 XPath 定位器和 JavaScript 片段，两者似乎都是正确的。我还尝试增加页面加载的超时时间，但错误仍然存在。

我觉得总的来说，我在使用 Salesforce 测试框架时遇到了问题。 有没有人遇到过类似的问题或对如何解决这个问题有任何建议？预先感谢您的帮助！

Answer 1

使用 SalesForce，我必须选择两个高于预期的父级别，单击

one-app-nav-bar-item-root

而不是锚标记。

要单击我的帐户选项卡，我使用了 xPath

//one-app-nav-bar-item-root/a/span[text()='Accounts']/parent::*/parent::*

，然后应用了单击。

/**
 * <p>This method will navigate to a tab open in the top of SalesForce using the tabs name.</p>
 * @param tabName The text displayed on the tab.  Not a URL.
 * @author <a href="https://stackoverflow.com/users/9889584/sjb">Shawn J Burke</a>
 */
public void navigateOneAppBarItem(String tabName) {
    String xPath = String.format("//one-app-nav-bar-item-root/a/span[text()='%s']/parent::*/parent::*", tabName);
    System.out.println(xPath);
    WebElement oneBarTab = this.getWebDriver().findElement(By.ByName.xpath(xPath));
    oneBarTab.click();
}
