How to Upload and Download a File Using Selenium Selenium is one of the most—if not the most—popular names for browser automation tools. By Testim , June 14, Share on. Selenium Flavors In the introduction, we said that Selenium is a popular browser automation tool commonly used in software testing. It actually contains different tools you can use according to your use cases: Selenium IDE is a browser extension you can use to create simple record-and-playback tests.
Selenium Grid is used for grid testing , also known as testing across different browsers and operating systems. Selenium WebDriver is an API you can use to drive a browser through the programming language of your preference.

That fourth line prints "None", presumably because I haven't manually clicked the Save button, and even if I had, I doubt WebDriver would be able to "see" the file.
Any ideas? As far as I know there is no easy way to make Selenium download files because browsers use native dialogs for it which cannot be controlled by JavaScript, so you need some "hack". Check this , hope it helps. Here's a solution. Set Firefox's preferences to save automatically, and not have the downloads window popup. Then you just grab the file, and it'll download. You can check the header response to check that you get a OK or maybe a redirect, depends on your expected outcome and it will tell you that a file exists.
Here is my implementation. This finds the link on the page and extracts the URL being linked to. It then uses apache commons to replicate the browser session used by selenium and then download the file. There are some instances where it won't work where the link found on the page does not actually link to the download file but a layer to prevent automated file download.
The response will contain the length of the file and it's type. A HEAD request is preferable since it will only retrieve the headers instead of pulling down the entire file. And if the file is behind auth, you will need to pull the session cookie from Selenium's cookie store and pass it into the HTTP library when performing the request. That, or you can configure the browser you're using to auto-download files to a specific location and then perform checks against the file on disk.
I made my own version of the downloader, by using an Ajax request and returning the bytes. Has the advantage that it uses the browser directly, so authentication and cookies do not need to be dealt with. It has the disadvantage that you're restricted by same-origin rule, it might need a lot of memory and maybe also fail in older browsers.
How to auto save files using custom Firefox profile? This blog post describes a straight forward way of invoking another library to download the file so not through the browser whilst maintaining selenium's session with the site - so it works on password-protected files, etc.
There are many ways to download file in Selenium, one of the easiest way in Firefox using Firefox Profile. First add preferences in profiles and specify the MIME type of file and then you can open Firefox with above preferences. I found below article interesting which cover above scenario: How to Download files in Selenium Webdriver. First, think about - do you really need to download an image? Or You just need to make sure that it exists and it is able to be downloaded?
Here you may find full trusted description how to check that image is available and exists, just by following by image's URL. Main steps are: extract authorization cookies if user session required use them for building new HTTP request send such request with image's URL to check status code if status code is - image exists.
Note, that it is not apache-like cookies, you can not use them strictly with apache http client. But you could build one apache-like based on it. An approach that I took I took recently to this was to capture to response via fiddler.
In my case I am making a call directly to the export handler in our application. I have wrapped the selenium bits and intercepted the traffic with fiddler core. I actually just cared about the data in the file not that the browser correctly interpreted the request. You could also accomplish this using the a click action as well. I am using C and WebDriver for my implementation.
If you are using a different language I think there are some other tools as well. I my opinion the advantage of this is that I can strip away having to try to interact with the file download mechanisms of any of the browsers.
If I want to create the file later all of the information the browser would have received is in the response header. A simple but somewhat flimsy solution depending on whether you're expecting a consistent screen size in your target environment ; is to use the java. Robot class as below.. You could also try the ChromeDriver for selenium; as I've noticed chrome doesn't have an OS dialogue for download confirmation.
When you are using selenium web driver with for Firefox profile , the best way to deal with the modal window is by changing the Firefox profile settings to automatically downloading the file to the desired location.
