java - 机器人框架 - Selenium Webdriver - Java : stale element reference exception when calling a global variable

Question

机器人框架 - Selenium Webdriver - Java:有人让我知道为什么在我的函数中调用全局变量时会出现陈旧元素引用异常。

我创建了下面的java方法并在Robot框架中调用了这个关键字。

public String CreateOpportunity()
{
    String OpportunityName = "Optimum Wartung"+RandomNumber();
    WaitAndClickElement("id",SalesforceOpportunityPageData.OpportunityTab);
    ClickOnElement("cssSelector", SalesforceOpportunityPageData.NewButton);
    SelectDropDownValues ("id",SalesforceOpportunityPageData.SiteCountryField,SalesforceOpportunityPageData.SiteCountryValue);
EnterValues("id",SalesforceOpportunityPageData.ProjectEndDateField,SalesforceOpportunityPageData.ProjectEndDateValue);
    ClickOnElement("cssSelector",SalesforceOpportunityPageData.SaveButton);
    return OpportunityName;
}
public void BeginAssess(String opportunityStr){
//opportunityString=CreateOpportunity(opportunityStr);
List<WebElement> opportunities = driver.findElements(By.xpath("//a[contains(@id,'offer-item')]"));
System.out.println("Entered into Begin Asses function "+ opportunityStr);

for(WebElement opportunite:opportunities)
{
    WebElement textele = opportunite.findElement(By.cssSelector("div.offer-name.no-contracts"));
    String textval = textele.getText();
    System.out.println("TextValue is: " + textval);
    if(textval.equalsIgnoreCase(opportunityStr))
    {
        WaitTillElementToBeClickable("cssSelector",CustomerPageData.OpportunityStatus);
        opportunite.findElement(By.cssSelector("div.opportunity-status")).click();
        System.out.println("Its clicked2");
    }
}
}   
public void WaitTillElementToBeClickable(String locatorType,String locatorVaue)
{
    try{
    WebDriverWait wait = new WebDriverWait(driver,200);

    if(locatorType.equalsIgnoreCase("cssSelector"))
        wait.until(ExpectedConditions.elementToBeClickable(By.cssSelector(locatorVaue)));

    else if(locatorType.equalsIgnoreCase("xpath"))
        wait.until(ExpectedConditions.elementToBeClickable(By.xpath(locatorVaue)));

    else if(locatorType.equalsIgnoreCase("id"))
        wait.until(ExpectedConditions.elementToBeClickable(By.id(locatorVaue)));
    }
    catch(Exception e){
        System.out.println("Webdriver Locator Error"+e);
    }
}

以下是 RF 代码。我创建了一个变量 ${Oppo} 并将其设置为全局变量，如下所示。并将这个变量传递给名为“Begin Assess”的关键字。它执行代码，但最终出现陈旧元素异常。我已经设置了等待条件，但仍然有相同的情况。帮我看看我哪里出错了。注意:我没有使用 selenium2library。仅使用 selenium webdriver。

*** Variable ***
${Oppo}
*** Test Cases ***
Create Opportunities in Salesforce Environment
  Logon To Salesforce
  ${Oppo}=  Create Opportunity
  Set Global Variable  ${Oppo}
Logon To KCC With Valid Credentials
  Logon To KCC
Verify the Salesforce Data is synchronized with KCC tool
  Update KCC Data
Complete The Assessment For An Opportunity
  Search Customer Account  Automation
  Expand Customer Account
  Begin Assess  ${Oppo}

更正的代码:

public void BeginAssess(String opportunityStr){
//opportunityString=CreateOpportunity(opportunityStr);
List<WebElement> opportunities = driver.findElements(By.xpath("//a[contains(@id,'offer-item')]"));
System.out.println("Entered into Begin Asses function "+ opportunityStr);

for(WebElement opportunite:opportunities)
{
    WebElement textele = opportunite.findElement(By.cssSelector("div.offer-name.no-contracts"));
    String textval = textele.getText();
    System.out.println("TextValue is: " + textval);
    if(textval.equalsIgnoreCase(opportunityStr))
    {
        WaitTillElementToBeClickable("cssSelector",CustomerPageData.OpportunityStatus);
        opportunite.findElement(By.cssSelector("div.opportunity-status")).click();
        System.out.println("Its clicked");
        break;
    }
}
}

如果你获取一个元素，然后在页面刷新后尝试使用该元素，你将得到一个陈旧元素异常。即使刷新结果完全相同的页面，所有元素都将变得“陈旧”。
