use a file selenium code example

Example 1: how to upload a file in selenium java

driver.findElement(By.id("urid")).sendKeys("drive:\\path\\filename.extension");

Example 2: uploading in selenium

In order to upload file using selenium we need to locate the upload button 
in the DOM html. Then we do sendKeys by passing the path to the file. 

First, I locate the element which takes the path of the file(Choose file button) :
      WebElement input = driver.findElement(“id”); 
 And then I provide the path to the file using the sendKeys method :
      input.sendKeys(“/path/to/file” + Keys.ENTER);
