File download with Selenium WebDriver

Most of the selenium user is facing problem while handling file download scenario.

In file downloading we have to deal with windows pop-up also we need to verify whether file is downloaded or not.

To deal with this scenario with have to work with firefox profile.

Below you can check the code, here you can verify file by its name or if name is randomly generated then you can verify file by its extension.

 @BeforeClass  
 public void Setup() throws Exception  
 {  
 driver = new FirefoxDriver(ffprofile());       
 File directory = new File(FIleDownloadPath);  
 delete(directory); //create a function delete with code to delete directory and its files  
 }  
   

//Method where user will download a file and then verify

 @Test  
 public void DownloadAndVerify()   
 {  
      driver.get(URL);  
        
 //Go to the place where link / button is placed for download  
 // Click on it to download file  
   
 Assert.assertTrue(VerifyFileDownloadWithName (FIleDownloadPath, "Name of file with extension"), "Failed to download Expected document");  
   
 //if file name is random then you can verify by extension  
 Assert.assertTrue(VerifyFileDownloadWithExtension (FIleDownloadPath, ".extension of file"), "Failed to download document which has extension ".extension of file ");  
 }  
   

  

//To set download functionality, with this download pop-up will not appeared

 

 public static FirefoxProfile ffprofile() throws Exception  
 {  
       FirefoxProfile firefoxProfile = new FirefoxProfile();  
       firefoxProfile.setPreference("browser.download.folderList",2);  
       firefoxProfile.setPreference("browser.download.manager.showWhenStarting",false);  
       firefoxProfile.setPreference("browser.download.dir",downloadPath);  
      firefoxProfile.setPreference "browser.helperApps.neverAsk.saveToDisk",  
      "text/csv,application/x-msexcel,application/excel,application/x-excel," +  
      "application/vnd.ms-excel,image/png,image/jpeg,text/html,text/plain,application/" +  
                     "msword,application/xml"  
             
       return firefoxProfile;  
 }  
   

//Verify file downloaded by its Name

 

 public boolean VerifyFileDownloadWithName (String FIleDownloadPath, String fileName)   
 {  
      boolean flag = false;  
      File dir = new File(FIleDownloadPath);  
      File[] dir_contents = dir.listFiles();  
           
      for (int i = 0; i < dir_contents.length; i++)   
      {  
           if (dir_contents[i].getName().equals(fileName))  
                 return flag=true;  
       }       
   
      return flag;  
 }  
   

//Verify file downloaded by its Extension

 

 private boolean VerifyFileDownloadWithExtension(String FIleDownloadPath, String ext)  
 {  
  boolean flag=false;  
  File dir = new File(FIleDownloadPath);  
  File[] files = dir.listFiles();  
  if (files == null || files.length == 0)   
  {  
      flag = false;  
  }  
  for (int i = 1; i < files.length; i++)   
  {     
       if(files[i].getName().contains(ext))   
          {   
             flag=true;   
           }  
   }   return flag;   
 }  
   

With this code, hope you are set to handle Download Functionality.
