如何检查新追加元素的文本是否等于字符串？ 我想在聊天中找到一个单词，但看起来我指的是同一个元素。
while (true){
try {
WebDriverWait wait = new WebDriverWait(driver, 5);
wait.until(ExpectedConditions.textToBePresentInElementLocated(By.xpath("//span[@class='msg-body']"), "Hello"));
System.out.println("Found Hello");
} catch (Exception e) {
System.out.println("Nothing found");
}
Thread.sleep(100);
}

到目前为止，我创建了元素列表，它的大小等于400项（当聊天填充消息时）;但是仍然想知道是否有可能跟踪新元素而不是循环400次。
elementList = driver.findElements(By.xpath("//span[@class='msg-body']"));
for (WebElement element: elementList) {
if (element.getText().equals("nice")) {
System.out.println("Done");
System.out.println("List size: " + elementList.size());
}
}
Thread.sleep(200);
答案 0 :(得分：0)
请检查一下让我知道。
我假设该消息将自动附加在dom中，其类似于
<span class="msg-body">which one u want?</span>
目标是获取最后一条附加消息的文本。我们可以知道消息的实例数，并获取最后一个消息的文本。
int size = driver.findElements(By.xpath("//span[@class='msg-body']")).size();
现在获取最后一条消息的文本。
String message = driver.findElement(By.xpath("//span[@class='msg-body'][" + size + "]")).getText();
以后的用户Java API或TestNG方法来验证字符串消息。
希望这会有所帮助。感谢。
