我希望在从Webdriver.get（urls）打开的多个实例上执行操作（切换到框架，NavigateToAgents和writeToExcel）。目前，它仅在打开的浏览器的第一个实例上运行其余动作（切换到框架，NavigateToAgents和writeToExcel），但在其他浏览器上不运行。
@Test(dataProvider = "data")
public static void stopAgents(String urls) throws Exception {
setup(); //Setup of browser
WebDriver.get(urls); // opening multiple instances of webdriver from list of urls from dataprovider
switchToLeftFrame();
navigateToAgents();
writeToExcel(sheetName, methodType); //i want to write to excel the tables of both the instances which are opened
// dataprovider传递网址列表
@DataProvider(name = "data", parallel = true)
public Object[][] data() {
Configuration configuration = Configuration.getConfiguration();
List<String> urls = configuration.getListOfUrls();
Object[][] data = new Object[urls.size()][1];
for (int i = 0; i < data.length; i++) {
data[i][0] = urls.get(i);
}
return data;
}
