[Selenium]验证点了某个Button之后无反应

期望：点了某个Button，无反应

问题：怎么去验证无反应

WebElement webElement = page.getICORemove();
SeleniumUtil.hover(page.getDriver(), webElement);
String beforeStr = (String) SeleniumUtil.getInnerHTML(page.getDriver(), page.getDLGDataColumnSetting());
webElement.click();
String newStr = (String) SeleniumUtil.getInnerHTML(page.getDriver(), page.getDLGDataColumnSetting());
Assert.assertEquals(newStr, beforeStr, "Click Remove,there are some changes.");

public static Object getInnerHTML(WebDriver driver, WebElement el) {
		String code = "var htmlTag=arguments[0].innerHTML;return htmlTag;";
		return ((JavascriptExecutor) driver).executeScript(code, el);
	}
