我可以调用Selenium中的AngularJS函数吗

Part of my web app has configuration that requires a file upload. This is currently implemented using AngularJS

我的web应用程序的一部分配置需要文件上传。这是目前使用AngularJS实现的。

<div ng-file-drop="onFileSelected($files)">Upload Files</div>

Dropping a file from the filesystem using Selenium seems nearly impossible and the SendKeys method wont work here as all I have is a div and not an input.

使用Selenium从文件系统中删除文件几乎是不可能的，SendKeys方法在这里不起作用，因为我只有一个div而不是一个输入。

The alternative seems to be to call the Angular function directly. How would I do this?

另一种方法似乎是直接调用角函数。我该怎么做呢?

I'm pretty sure you can still find an input with type="file" in your DOM.

我确信您仍然可以在DOM中找到type="file"的输入。

Let's take a look at an example Angular File Upload DEMO page. There is a ng-file-upload div that you can drag and drop files onto, but, if you would inspect the DOM, you'll see a hidden file input element that is actually responsible for the upload.

让我们看一个角度文件上传演示页面的例子。有一个ng-file-upload div可以拖放文件到上面，但是，如果您要检查DOM，您将看到一个隐藏的文件输入元素，它实际上负责上传。

What we can do in tests is make the input visible so that we can interact with it and send keys to it containing an absolute path to a file to upload. Example code to make the file input visible:

我们在测试中可以做的是使输入可见，这样我们就可以与它交互，并将包含绝对路径的键发送到要上载的文件。使文件输入可见的示例代码:

WebElement fileInput = driver.findElement(By.cssSelector("input[ng-model=files]"));

JavascriptExecutor js = (JavascriptExecutor) driver;
js.executeScript("arguments[0].style.visibility = 'visible'; arguments[0].style.overflow = 'visible'; arguments[0].style.height = '1px'; arguments[0].style.width = '1px'; arguments[0].style.opacity = 1", fileInput);

fileInput.sendKeys("/absolute/path/to/a/file");

Sample code that works for the for the provided fiddle:

为提供的小提琴工作的示例代码:

driver.switchTo().frame("result");

// waiting for the element to appear
WebDriverWait wait = WebDriverWait(driver, 10);
WebElement fileInput = wait.until(ExpectedConditions.presencefElementLocated(By.cssSelector("input[ng-model=file]")));

// making the element visible
JavascriptExecutor js = (JavascriptExecutor) driver;
js.executeScript("arguments[0].style.visibility = 'visible'; arguments[0].style.overflow = 'visible'; arguments[0].style.height = '1px'; arguments[0].style.width = '1px'; arguments[0].style.opacity = 1",
    fileInput);

fileInput.sendKeys("/absolute/path/to/the/file")

Once the path is sent to the input, the upload process is triggered.

一旦路径被发送到输入，就会触发上传过程。
