Testing file download

Learn how to test the file download functionality using Automate TurboScale.

BrowserStack enhances your Selenium testing suite by offering features to streamline file download interactions within web applications. These features are especially useful when testing scenarios like invoice generation, PDF downloads, and other file-centric workflows.

Download files on Browserstack remote instances

To download files on BrowserStack’s remote instances, integrate the custom browserstack_executor script into your Automate TurboScale sessions. The following sample code illustrates its use in Selenium:

Work with the downloaded file

BrowserStack provides a range of JavaScript executors to help you work with downloaded files. Use the following tabs to learn about different Javascript executors:

Protip: Any of the custom Javascript executors will work even if fileName argument is not passed. The results will be for the last downloaded file in the session. 
System.out.println(jse.executeScript("browserstack_executor: {\"action\": \"fileExists\", \"arguments\": {\"fileName\": \"<file name>\"}}"));

await driver.executeScript('browserstack_executor: {"action": "fileExists", "arguments": {"fileName": "<file name>"}}')

driver.ExecuteScript('browserstack_executor: {"action": "fileExists", "arguments": {"fileName": "<file name>"}}');

driver.execute_script('browserstack_executor: {"action": "fileExists", "arguments": {"fileName": "<file name>"}}')

caps['javascriptEnabled'] = 'true' #Additionally, include this capability for JavaScript executors to work

driver.execute_script('browserstack_executor: {"action": "fileExists", "arguments": {"fileName": "<file name>"}}')

The fileExists function within the browserstack_executor script returns a boolean value as a response.

Use the above code snippets to verify whether a specific file was downloaded.

Protip: The following snippet verifies whether the last file was downloaded in the test session. 
System.out.println(jse.executeScript("browserstack_executor: {\"action\": \"fileExists\"}"));

await driver.executeScript('browserstack_executor: {"action": "fileExists"}')

driver.ExecuteScript('browserstack_executor: {"action": "fileExists"}');

driver.execute_script('browserstack_executor: {"action": "fileExists"}')

caps['javascriptEnabled'] = 'true' #Additionally, include this capability for JavaScript executors to work

driver.execute_script('browserstack_executor: {"action": "fileExists"}')

System.out.println(jse.executeScript("browserstack_executor: {\"action\": \"getFileProperties\", \"arguments\": {\"fileName\": \"<file name>\"}}"));

await driver executeScript('browserstack_executor: {"action": "getFileProperties", "arguments": {"fileName": "<file name>"}}')

driver.ExecuteScript('browserstack_executor: {"action": "getFileProperties", "arguments": {"fileName": "<file name>"}}');

driver.execute_script('browserstack_executor: {"action": "getFileProperties", "arguments": {"fileName": "<file name>"}}')

caps['javascriptEnabled'] = 'true' #Additionally, include this capability for JavaScript executors to work

driver.execute_script('browserstack_executor: {"action": "getFileProperties", "arguments": {"fileName": "<file name>"}}')

You can verify the integrity of the downloaded file using the getFileProperties function in your code using the above code snippet. The function returns a JSON response as follows:

{
  "created_time": 1607951826,
  "md5": "71d277eaaa7b2ba6f63eda04dad1a6b4",
  "changed_time": 1607951826,
  "modified_time": 1607951826,
  "size": 3187,
  "file_name": "Browserstack-List of devices to test.csv"
}

The properties’ parameters are defined as follows:

  • created_time: The time when file was downloaded.
  • md5: The md5 checksum value of the downloaded file. You can verify the integrity of the file using this value.
  • changed_time: The time at which the file permission or file content is changed.
  • modified_time: The time at which the file content is changed.
  • size: The size of the downloaded file.
  • file_name: The name of the downloaded file.
System.out.println(jse.executeScript("browserstack_executor: {\"action\": \"getFileContent\", \"arguments\": {\"fileName\": \"<file name>\"}}"));

await driver.executeScript('browserstack_executor: {"action": "getFileContent", "arguments": {"fileName": "<file name>"}}')

driver.ExecuteScript('browserstack_executor: {"action": "getFileContent", "arguments": {"fileName": "<file name>"}}');

driver.execute_script('browserstack_executor: {"action": "getFileContent", "arguments": {"fileName": "<file name>"}}')

caps['javascriptEnabled'] = 'true' #Additionally, include this capability for JavaScript executors to work

driver.execute_script('browserstack_executor: {"action": "getFileContent", "arguments": {"fileName": "<file name>"}}')

You can transfer the downloaded file from the BrowserStack remote instance to your machine using the getFileContent function that returns the downloaded file as a Base64-encoded string. If you do not know the file name, you can get the content of the last downloaded file in the session by omitting the fileName argument. Use 'browserstack_executor: {"action": "getFileContent"}' and save the response in your local system as shown in the above code sample.

You can use the BrowserStack executor, getFileContent, to download a file that’s up to 30 MB in size.
