Selenium give file name when downloading

Here is another simple solution, where you can wait until the download completed and then get the downloaded file name from chrome downloads.

Chrome:

# method to get the downloaded file name
def getDownLoadedFileName(waitTime):
    driver.execute_script("window.open()")
    # switch to new tab
    driver.switch_to.window(driver.window_handles[-1])
    # navigate to chrome downloads
    driver.get('chrome://downloads')
    # define the endTime
    endTime = time.time()+waitTime
    while True:
        try:
            # get downloaded percentage
            downloadPercentage = driver.execute_script(
                "return document.querySelector('downloads-manager').shadowRoot.querySelector('#downloadsList downloads-item').shadowRoot.querySelector('#progress').value")
            # check if downloadPercentage is 100 (otherwise the script will keep waiting)
            if downloadPercentage == 100:
                # return the file name once the download is completed
                return driver.execute_script("return document.querySelector('downloads-manager').shadowRoot.querySelector('#downloadsList downloads-item').shadowRoot.querySelector('div#content  #file-link').text")
        except:
            pass
        time.sleep(1)
        if time.time() > endTime:
            break

Firefox:

def getDownLoadedFileName(waitTime):
    driver.execute_script("window.open()")
    WebDriverWait(driver,10).until(EC.new_window_is_opened)
    driver.switch_to.window(driver.window_handles[-1])
    driver.get("about:downloads")

    endTime = time.time()+waitTime
    while True:
        try:
            fileName = driver.execute_script("return document.querySelector('#contentAreaDownloadsView .downloadMainArea .downloadContainer description:nth-of-type(1)').value")
            if fileName:
                return fileName
        except:
            pass
        time.sleep(1)
        if time.time() > endTime:
            break

Once you click on the download link/button, just call the above method.

 # click on download link
 browser.find_element_by_partial_link_text("Excel").click()
 # get the downloaded file name
 latestDownloadedFileName = getDownLoadedFileName(180) #waiting 3 minutes to complete the download
 print(latestDownloadedFileName)
 

JAVA + Chrome:

Here is the method in java.

public String waitUntilDonwloadCompleted(WebDriver driver) throws InterruptedException {
      // Store the current window handle
      String mainWindow = driver.getWindowHandle();
      
      // open a new tab
      JavascriptExecutor js = (JavascriptExecutor)driver;
      js.executeScript("window.open()");
     // switch to new tab
    // Switch to new window opened
      for(String winHandle : driver.getWindowHandles()){
          driver.switchTo().window(winHandle);
      }
     // navigate to chrome downloads
      driver.get("chrome://downloads");
      
      JavascriptExecutor js1 = (JavascriptExecutor)driver;
      // wait until the file is downloaded
      Long percentage = (long) 0;
      while ( percentage!= 100) {
          try {
              percentage = (Long) js1.executeScript("return document.querySelector('downloads-manager').shadowRoot.querySelector('#downloadsList downloads-item').shadowRoot.querySelector('#progress').value");
              //System.out.println(percentage);
          }catch (Exception e) {
            // Nothing to do just wait
        }
          Thread.sleep(1000);
      }
     // get the latest downloaded file name
      String fileName = (String) js1.executeScript("return document.querySelector('downloads-manager').shadowRoot.querySelector('#downloadsList downloads-item').shadowRoot.querySelector('div#content #file-link').text");
     // get the latest downloaded file url
      String sourceURL = (String) js1.executeScript("return document.querySelector('downloads-manager').shadowRoot.querySelector('#downloadsList downloads-item').shadowRoot.querySelector('div#content #file-link').href");
      // file downloaded location
      String donwloadedAt = (String) js1.executeScript("return document.querySelector('downloads-manager').shadowRoot.querySelector('#downloadsList downloads-item').shadowRoot.querySelector('div.is-active.focus-row-active #file-icon-wrapper img').src");
      System.out.println("Download deatils");
      System.out.println("File Name :-" + fileName);
      System.out.println("Donwloaded path :- " + donwloadedAt);
      System.out.println("Downloaded from url :- " + sourceURL);
     // print the details
      System.out.println(fileName);
      System.out.println(sourceURL);
     // close the downloads tab2
      driver.close();
     // switch back to main window
      driver.switchTo().window(mainWindow);
      return fileName;
  }

This is how to call this in your java script.

// download triggering step 
downloadExe.click();
// now waituntil download finish and then get file name
System.out.println(waitUntilDonwloadCompleted(driver));

Output:

Download deatils
