Create and upload a file on selenium grid

Question

One of tthe test cases that I have is to upload a file to the application. Witouth grid this can be easily done by creating a bogus file and get absolute path of the file and fill the input field and click upload. However when I am using grid, the file is not on the machine that hosted the node. Is there anyway to either send the file to the node or tell the node to create the file and get the absolute path.

Answer 1

It's actually pretty simple once you know how, just set a local file detector.

import org.openqa.selenium.remote.LocalFileDetector
import org.openqa.selenium.remote.RemoteWebDriver

WebDriver driver = new RemoteWebDriver(new URL("http://localhost:4444/wd/hub"), DesiredCapabilities.firefox());
driver.setFileDetector(new LocalFileDetector())

Then just upload as normal and Selenium will fire the file across the wire to the node.

does the file created in the node or locally? – Recline

In the above example the file would be on the machine running the tests. The file will then be sent over the wire to the grid, and then on to the node so that the node can upload the file. – Wanitawanneeickel

Impressed by developers' humor - there is only two FileDetector implementations: one is mentioned LocalFileDetector, the other is UselessFileDetector "that never finds anything" :) – Hassanhassell

nitpicking - setFileDetector can not be called on driver object but driver needs to be downcast to RemoteWebDriver - ((RemoteWebDriver)driver).setFileDetector(new LocalFileDetector()); – Dealing

Answer 2

You can do it in normal way as you create a file on local machine. See below,

File file = new File("\\\\00.00.00.00\\c$\\somefile.txt");
file.createNewFile();

This will create a file called somefile.txt in 'C' drive on the remote machine. Change the IP address to your remote machine.

hmm.. but when i run it in the selenium grid then the node is kinda random right? I don't know which node it is going to run – Recline

You can write a method and call it in test methods where ever required. It's independent of nodes. – Maurits

unless remote machine is not windows hence does not have neither the 'C' drive nor samba installed – Hassanhassell
