Instruction: How to Check That a File Was Downloaded

How it works

1. Setup browser.download.folder variable to a required folder. For example D:\downloads.
   It will work only for local installation because on cloud/demo user can access to filesystem and do whatever he want.
    
   
2. Restart Screenster (Go to Services -> Select Screenster -> restart it)
    
   
3. Go to Parameters tab and add two parameters (fileName – which will be downloaded and downloadFolder – the same, as in settings):
    
   
4. Record a test with clicking on the link/button for download target file.
5. Add Selenium command after Click command with the next code:
    

   package commands;

   import com.agileengine.screenster.logic.browsers.Browser;
   import org.openqa.selenium.WebDriver;
   import org.openqa.selenium.By;
   import org.testng.Assert;
   import java.util.Map;
   import utils.Screenster;
   import java.io.File;
   import org.openqa.selenium.support.ui.FluentWait;
   import java.util.concurrent.TimeUnit;

   public class SeleniumCommand {
    public void run(WebDriver driver, Browser browser, Map parameters) throws Exception {
     //get folder and file name from parameters
     String fileName = parameters.get(“fileName”);
     String downloadFolder = parameters.get(“downloadFolder”);
     File targetFile = new File(downloadFolder, fileName);
     //max time to download in seconds
     int downloadTime = 20;
     waitForFile(driver, targetFile, downloadTime);
     //if file is not present – fail test
     if (!targetFile.exists()) {
      Screenster.failTest(“File is not present”);
     } else {
      //delete file to be sure that next time new file will be downloaded
      targetFile.delete();
     }
    }

    /**
    * Wait for a file till some timeout (in seconds)
    */
    public void waitForFile(WebDriver driver, File file, long timeout) {
     FluentWait wait = new FluentWait(driver)
      .withTimeout(timeout, TimeUnit.SECONDS)
      .pollingEvery(1, TimeUnit.SECONDS);
     wait.until((webDriver) -> file.exists());
    }
   }

   You can increase downloadTime if needed.
