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.

Now live: A fully responsive profile. Reducing the weight of our footer. Visit chat. This feature is available in all the official Selenium 2 bindings from Selenium 2. Here are some examples tests:. At any case, Do not click on browse button to upload file. This will open up OS native file explorer and halt the tests since selenium cannot handle those kind of stuffs. Also please note that this does not affect local test execution and comes into play only when tests are running in remote server.
This sample is to run tests in remote machine and refer files from local i. There are other options like AutoIt and java in built Robot class available to handle this kind of scenario. When you download a file using dockerized selenium grid, It downloads and keeps the downloaded file inside the container.
It can control the browser inside the container via RemoteWebDriver object. But, there is no way to access container directory.
In this case, How can we assert that file has been downloaded? So you could map them to a directory somewhere in your host machine. Now, when I use docker selenium grid with volume mapping, the downloaded file is present in my host machine in the specific directory which I mapped.
I would suggest you to take a look at the awaitility library as shown above to wait for actions to complete. Check this article on that. This is great, so far! But, What about your tests itself runs inside a container as shown in the articles below.!?
How can 2 containers share the file system? Docker volume mapping will help here as well. In this case, we do the mapping twice. One for your browser node — to get the file in the host directory as we saw above and another mapping for your test container.
This is to map the host directory which has the file to your container directory. So that your tests inside the container could see the file. Here are some examples tests: Java. Pro tip: Write your own FileHandler that will use special codes to represent files before typing paths locally or uploading them remotely. Example: "test-file:small-image".
