I am trying to run javascript mocha selenium-webdriver tests on my company's application using docker containers. I seem to have everything working except that I am unable to upload files. Prior to trying use my tests in a docker environment I was able to use it on our local servers and upload files with no issue using the a method like this:

const companyImage = process.cwd()+ '/img/backgroundmario.jpg';
const companyImageElem = await driver.findElement(By.xpath("//div/input[@type='file']"));
await companyImageElem.sendKeys(companyImage);

However, I have not been able to have any success when using docker containers. I mounted my img folder to my selenium/node-chrome-debug container which includes a VNC viewer and I can see that the images are present (and I can manually upload the images via the VNC viewer). However, despite numerous variations of providing paths to the images I cannot seem to get my images to upload. For some reason the working directory seems to be from my test container and not my node-chrome-debug container but even if I add the images to the test container and change the path to my test container directory with the images they do not upload either.

Here is a snippet of my code I am using for my test (it includes some stuff I wouldn't normally include, specifically the check for process.cwd() and process.env.PWD since I just wanted to see what the path was):

This is the last thing stopping me from integrating my large number of test files with our CI/CD process but a huge number of my tests involve uploading files so it is a major issue.

Note: This is an edited copy of a question I asked on Stack Overflow. I am getting desperate because of my lack of progress.

Update: The error I am receiving is: InvalidArgumentError: invalid argument: File not found : /opt/test/images/backgroundmario.jpg (Session info: chrome=77.0.3865.75). This is puzzling to me in several ways based on what I have read and what people in the official Selenium Slack channel had told me.

First of all, in my docker_test_1 container (which contains the test file) the path opt/test/images/<filename> actually does point to the file. However, I was told in the Selenium Slack that I needed to have my images in the node-chrome-debug container with the path opt/images

So I mounted the images folder to the selenium-chrome-debug container in opt/images but if I use that path in my test file it does not attach the image either and I receive a similar error. However, if I use VNC viewer I can see that in opt/images the images are there and I can manually upload them through the VNC browser. So despite trying numerous paths I can not seem to get my images to upload despite the fact that when running my tests on a local environment without docker the images upload without issue.

Another thing that puzzled me is that the result of

var currentDir = process.cwd(); 
var appFolder = process.env.PWD; 

is opt/test when I would have assumed that it would have been the working directory for the selenium-node-chrome container based on what I was told in the Selenium Slack channel.

I tried changing the path for my images to opt/test/images/ but they still do not upload.

I am not someone who tries ask questions for something that is a simple google search away but I have been struggling for several days with this issue and I can't seem to find any solution or helpful advice.

  • Please don't cross-post; delete one or the other. – jonrsharpe Sep 25 at 6:44
  • So no useful suggestions regarding the situation at hand. Simply 2 suggestions to edit the post for "clarity" and a comment statingto not cross-post when as far as I knew stack-overflow and the QA section were pretty much independent of one another. I can really tell that this is a great community full of knowledge as far as I can tell. Where else could I find such in-depth assistance germane to the matter at hand. Is this just an area where technical questions are not answered or only the most basic ones are? I can't imagine that any serious QA using automation has not faced this issue. – Seetherrr Sep 26 at 7:29
  • First: the edit you reverted did make your question clearer and easier to understand.Second, there is a fair amount of membership overlap between SO and SQA stack exchange, so cross-posting between the two will be noticed and not appreciated. Third, what errors do you get? Where are you placing your files that need to be uploaded? Is the user interacting with the image the same as the user when you upload manually? Does the image report any errors in its logs? Fourth, advanced programming questions are more likely to get good answers from SO. Simple programming questions on SO get downvoted. – Kate Paulk Sep 26 at 12:24
  • I have reverted the reversion, and will now edit to make it clear that this is the edited copy of a question on SO. – Kate Paulk Sep 26 at 12:30
  • I have copied the information from your comments to the question - please edit the question with new information rather than posting it to the comments. The information you have added leads me to suspect a permissions issue, since the file is present in the directory when you manually inspect the container. That suggests that your code is running as a user who is not you, and that user does not have permission to view the file. I'd suggest dropping in some debug code to list the files in the directory and work out exactly what the problem is. – Kate Paulk Sep 27 at 11:50

Despite not receiving any guidance here other than someone wanting to edit my text for clarity despite providing any actual value as far as the actual question goes, I was able to find a solution to the issue based on some additional research, some help from a coworker and some experimentation.

So there are several aspects that are important. First of all, you must make sure that the images you want to upload are mounted to the container with your browser (in my case, selenium/node-chrome-debug). Then you must make some additions to your test Selenium test file.

You must add the following lines:

var path = require('path');
var remote = require('selenium-webdriver/remote');

You can use var or let although I've been told that let is a better standard practice.

Then, after the line

driver = new Builder().forBrowser('chrome').usingServer('http://selenium_hub:4444/wd/hub').build();

Add this line of code

driver.setFileDetector(new remote.FileDetector());

For your the file you wish to upload, you must set the path to that of the file system on the browser container (selenium/node-chrome-debug in my case). So your file variable would be something like:

const companyImage = process.cwd()+'/images/backgroundmario.jpg';

Then, when you want to upload the file, you find the respective element using whichever form of identification you like and add a little extra to the sendKeys function in comparison to how you would do it were you simply running the script on your local file system rather than a docker container. So the code would look like this:

await driver.findElement(By.xpath("//input[@type='file']")).sendKeys(path.resolve(__dirname, companyImage));

Maybe there is a slightly cleaner way to code it (for example, I generally declare the elements I am interacting with as variables) but the example I have provided will work. It took me a lot of time and effort to find this solution so I hope this eventually saves someone else the amount of pain I experienced trying to get this to work.

While I hope this answer saves someone some time facing this issue I would say that the QA section of Stack Exchange seems to be largely useless as far as the input provided and I am completely turned off by my experience. Thanks a lot for that Kate Paulk. I sincerely hope you are feeling the effects of the wage gap since rather than trying to address an issue you decided to attack minute aspects of how the issue was phrased.
