How to Handle File Uploads Using Katalon Studio

In general, we need to automate scenarios like uploading a file into the application for attaching profile pictures or documents. This tutorial demonstrates handling the file upload feature and verifying downloaded files.

File Upload

The file upload widget is the input tag having attribute type equal to file. It allows us to upload all file formats (.jpg, .png, .txt…)

Let’s work on the case in which we need to upload a file and validate whether the file is uploaded.

Steps:

• Launch the URL of the application
• Maximize the window
• Use the file upload widget to upload a file

Manual Mode:

We can also use the script mode. The script below is the code to upload a file and validate the uploaded file.

Script Mode:

'Open browser and navigate to given URL'
WebUI.openBrowser('C:\\\\Users\\\\User\\\\Desktop\\\\Katalon Articles\\\\File Upload\\\\UploadFile.html')
'Maximize the window\r\n'
WebUI.maximizeWindow()
'Passing the path of the file'
WebUI.uploadFile(findTestObject('Upload File'), 'C:\\\\Users\\\\Public\\\\Pictures\\\\Sample Pictures\\\\Desert.jpg')

'Capturing the file name after upload and storing it in a variable'
FilePath = WebUI.getAttribute(findTestObject('Upload File'), 'value')

'Verifying the Actual path and Expected path of file'
WebUI.verifyMatch(FilePath, 'C:\\fakepath\\Desert.jpg', false)

File Upload Using Send Keys

We can also upload files by using the Send Keys method. Send Keys works for the input tag having type equal to file.

Steps:

• Launch the URL of the application
• Maximize the window
• Use the Send Keys method to upload a file
• Send Keys accepts file URL as a string

Manual Mode:

Script Mode:

'Open browser and navigate to given URL'

WebUI.openBrowser('C:\\\\Users\\\\User\\\\Desktop\\\\Katalon Articles\\\\File Upload\\\\UploadFile.html')

'Maximize the window\r\n'

WebUI.maximizeWindow()

'Uploading the File using Send Keys method by passing the File path'

WebUI.sendKeys(findTestObject('Upload File'), 'C:\\\\Users\\\\Public\\\\Pictures\\\\Sample Pictures\\\\Desert.jpg')

'Capturing the file name after upload and storing it in a variable'

FilePath = WebUI.getAttribute(findTestObject('Upload File'), 'value')

'Verifying the Actual path and Expected path of file'

WebUI.verifyMatch(FilePath, 'C:\\fakepath\\Desert.jpg', false)

Verify a Downloaded File

After downloading a file from the application we need to verify whether the file is successfully downloaded and saved in a folder.

For that, we need to set preferences for Firefox, as shown in the image below.

Script Mode:

import org.openqa.selenium.By as By
import org.openqa.selenium.WebDriver as WebDriver
import org.testng.Assert as Assert
import com.kms.katalon.core.webui.driver.DriverFactory as DriverFactory
import com.kms.katalon.core.webui.keyword.WebUiBuiltInKeywords as WebUI
import internal.GlobalVariable as GlobalVariable

 'Define Custom Path where file needs to be downloaded'
String downloadPath = 'D:\\FileDownloadChecking'

'Launch a browser and Navigate to URL'
WebUI.openBrowser(GlobalVariable.FileDownloadCheckingURL)

WebDriver driver = DriverFactory.getWebDriver()

'Clicking on a Link text to download a file'
driver.findElement(By.linkText('smilechart.xls')).click()
'Wait for Some time so that file gets downloaded and Stored in user defined path'
WebUI.delay(10)

'Verifying the file is download in the User defined Path'
Assert.assertTrue(isFileDownloaded(downloadPath, 'smilechart.xls'), 'Failed to download Expected document')

boolean isFileDownloaded(String downloadPath, String fileName) {
 boolean flag = false 'Creating an object for File and passing the download Path as argument'
 File dir = new File(downloadPath)
 'Creating an Array where it will store all the files from that folder'
 File[] dir_contents = dir.listFiles()

 println('Total Files Available in the folder are : ' + dir_contents.length)
 'Iterating a loop for number of files available in the folder to verify file name in the folder'
 for (int i = 0; i < dir_contents.length; i++) {
  println('File Name at 0 is : ' + dir_contents[i].getName())
  'Verifying the file name is available in the folder '
  if (dir_contents[i].getName().equals(fileName)) {
   'If the file is found then it will return a value as true'
   return flag = true
  }
 }
 'If the file is found then it will return a value as false'
 return flag
}
