Local file detector
The Local File Detector allows the transfer of files from the client machine to the remote server. In case a test needs to upload a file to a web application, a remote WebDriver can automatically transfer the file from the local machine to the remote web server during runtime. This allows the file to be uploaded from the remote machine running the test. It is not enabled by default and can be enabled as follows:
Java:
driver.setFileDetector(new LocalFileDetector());
Python:
from selenium.webdriver.remote.file_detector import LocalFileDetector
driver.file_detector = LocalFileDetector()
C#:
var allowsDetection = this.driver as IAllowsFileDetection;
if (allowsDetection != null)
{
allowsDetection.FileDetector = new LocalFileDetector();
}
This usecase
If you are running your tests on Selenium Grid then you need to let your remote driver know that the file that needs to be uploaded is residing on the local machine and not on remote machine. In those cases, to upload a file from the client machine to the remote server, WebDriver can automatically transfer the file from the local machine to the remote web server during runtime you can use the following code block:
WebElement addFile = driver.findElement(By.xpath("//input[@type='file']"));
((RemoteWebElement)addFile).setFileDetector(new LocalFileDetector());
addFile.sendKeys("C:\\daten\\test2.xml");
