我想在表格的每一行中选择一个元素。行和列没有该实际值，仅用于测试。
该行的cssSelector为div.table_row。单元格的cssSelector是div.table_cell。
如何从每行的5列中随机选择一个元素，然后移至下一行并随机选择另一个元素？
我尝试这样做，但是当然失败了：
Random rnd = new Random();
List<WebElement> button = driver.findElements(By.cssSelector(RADIO_BUTTON));
button.get(rnd.nextInt(button.size())).click();
其中RADIO_BUTTON是cssSelector div.radio_button。这将随机选择10个单选按钮，测试将失败。
请参见表格图像here。
在Java中用硒尝试。我对cssSelectors中的父元素和子元素不熟悉。XPath不在讨论之列，因为这些类是随机生成的，并且每次都会失败。
我希望它类似于this。
谢谢！

您可以尝试这样的方法：
List<WebElement> tableRows = driver.findElements(By.cssSelector("div.table_row"));
// iterating over rows
for(WebElement row: tableRows){
// Count number of cells in a row
List<WebElement> columsInRows = row.findElements(By.cssSelector("div.table_cell"));
Random rnd = new Random();
// Take random item in a row
int cellIndexToClick = rnd.nextInt(columsInRows.size());
// Click that item
columsInRows.get(cellIndexToClick).click();
}
我可以提供一些代码来帮助您入门。此代码将首先找到所有表行，然后在每行中随机选择一个单元格进行选择。我实际上没有在您提供的HTML中看到任何radio_button，所以我猜测一下并假设<div class="table_cell_text"></div>是单选按钮元素：
// init random
Random rnd = new Random();
// first get number of rows -- this returns 10
int rowCount = driver.findElements(By.xpath("//div[contains(@class, 'table_row')]")).size();
// then iterate the rows from 2-10 (WebElement lists are 1-based index, skip first header row)
for (int i = 2; i <= rowCount; i++)
{
// get radio buttons for this row -- use i to get the row index
// this returns 6
List<WebElement> cells = driver.findElements(By.xpath("//div[contains(@class, 'table_row')][" + i + "]//div[@class='table_cell_text']")
// get a random cell and click it -- start with 1 so we can skip first column
cells.get(rnd.nextInt((cells.size() - 1) + 1).click();
}
我从2开始for循环，因为我们不想用列标题a，b，c，d等查看第一行。我还指定了rnd.nextInt在1和[C0之间选择]，这样我们就不会选择第一列中包含数据1,2,3,4等的单元格。
