我對自動化測試完全陌生。在參考一些教程後,我創建了一個自動化測試用例。我嘗試自動化的測試用例是在點擊某個表頭之後檢查排序是否正確。StaleElementReferenceException:元素不再連接到DOM:Selenium
我自動化測試用例失敗,但以下情況除外:
org.openqa.selenium.StaleElementReferenceException: Element is no longer attached to the DOM
Command duration or timeout: 12 milliseconds

以下是代碼:
//Fetching values from the column of a table
WebElement table = driver.findElement(By.id("dnn_ctr381_View_DealerList_ctl00"));
List<WebElement> rows = table.findElements(By.tagName("tr"));
for (WebElement row : rows) {
List<WebElement> cells = row.findElements(By.tagName("td"));
if (!cells.isEmpty() && cells.get(0).isDisplayed()) {
a = cells.get(0).getText();
}
b[i] = a;
i++;
}
//Click on column header to sort
driver.findElement(By.cssSelector("html body#Body form#Form div#container.container div#Wrapper div#Main div#Panes div#ContentsContainer.box-shadow div#Contents div#Content div#dnn_ContentPane.MainContent div.DnnModule div.dnnPEMContNotitle div#dnn_ctr381_ContentPane.dnnPEMContNotitleBody div#dnn_ctr381_ModuleContent.DNNModuleContent div#dnn_ctr381_View_dnn_ctr381_View_DealerListPanel div#dnn_ctr381_View_DealerList.RadGrid table#dnn_ctr381_View_DealerList_ctl00.rgMasterTable thead tr th.rgHeader a")).click();
WebElement table1 = driver.findElement(By.id("dnn_ctr381_View_DealerList_ctl00"));
List<WebElement> rows1 = table1.findElements(By.tagName("tr"));
for (WebElement row1 : rows1) {
List<WebElement> cells1 = row1.findElements(By.tagName("td"));// Exception here
if (!cells1.isEmpty() && cells1.get(0).isDisplayed())
{
c = cells1.get(0).getText();
}
異常是從該行:
List<WebElement> cells = row1.findElements(By.tagName("td"));
可有人請讓我知道這個問題的原因以及它如何解決?
