Selenium 自动接受警报

Selenium automatically accepting alerts(Selenium 自动接受警报)

问题描述

有谁知道如何禁用它?或者如何从已自动接受的警报中获取文本?

Does anyone know how to disable this? Or how to get the text from alerts that have been automatically accepted?

这段代码需要工作，

driver.findElement(By.xpath("//button[text() = "Edit"]")).click();//causes page to alert() something
Alert alert = driver.switchTo().alert();
alert.accept();
return alert.getText();

但是却给出了这个错误

No alert is present (WARNING: The server did not provide any stacktrace information)
Command duration or timeout: 2.14 seconds

我正在使用带有 Selenium 2.32 的 FF 20

推荐答案

就在前几天我回答了类似的问题，所以它仍然很新鲜.您的代码失败的原因是，如果在处理代码时未显示警报，它将大部分失败.

Just the other day i've answered something similar to this so it's still fresh. The reason your code is failing is if the alert is not shown by the time the code is processed it will mostly fail.

谢天谢地，来自 Selenium WebDriver 的人已经为它实现了等待.因为你的代码就这么简单:

Thankfully, the guys from Selenium WebDriver have a wait already implemented for it. For your code is as simple as doing this:

String alertText = "";
WebDriverWait wait = new WebDriverWait(driver, 5);
// This will wait for a maximum of 5 seconds, everytime wait is used

driver.findElement(By.xpath("//button[text() = "Edit"]")).click();//causes page to alert() something

wait.until(ExpectedConditions.alertIsPresent());
// Before you try to switch to the so given alert, he needs to be present.

Alert alert = driver.switchTo().alert();
alertText = alert.getText();
alert.accept();

return alertText;

您可以从 ExpectedConditions 这里，如果你想要这个方法背后的代码这里.

You can find all the API from ExpectedConditions here, and if you want the code behind this method here.

这段代码也解决了这个问题，因为关闭警报后无法返回alert.getText()，所以我为你存储在一个变量中.

This code also solves the problem because you can't return alert.getText() after closing the alert, so i store in a variable for you.
