Delete Download stuff after run on Selenium Remote Note

To delete a file from the remote Selenium node, you have a few options. However, keep in mind that Selenium itself does not provide functionality to interact with the file system for operations like file deletion. Instead, you would have to utilize other means to perform such operations. Here are some methods you could consider:

1. SSH (Secure Shell) Access:

If you have SSH access to the remote node, you can execute a command to delete the file. You can use an SSH client library such as JSch in Java to run commands on the remote machine.

Here's a basic example using JSch to delete a file:

import com.jcraft.jsch.JSch;
import com.jcraft.jsch.Session;
import com.jcraft.jsch.ChannelExec;

public class DeleteRemoteFile {
    public static void deleteFile(String username, String password, String host, String filePath) {
        int port = 22; // Default SSH port

        try {
            // Create a new JSch instance
            JSch jsch = new JSch();

            // Create a session
            Session session = jsch.getSession(username, host, port);
            session.setPassword(password);
            session.setConfig("StrictHostKeyChecking", "no"); // Bypass host key check for this example

            // Connect to the session
            session.connect();

            // Open an exec channel
            ChannelExec channel = (ChannelExec) session.openChannel("exec");

            // Command to delete the file
            String command = "rm -f " + filePath;

            // Set the command
            channel.setCommand(command);

            // Connect the channel
            channel.connect();

            // Check if the command execution was successful
            int exitStatus = channel.getExitStatus();
            if (exitStatus == 0) {
                System.out.println("The file was deleted successfully.");
            } else {
                System.out.println("File deletion failed.");
            }

            // Disconnect the channel and session
            channel.disconnect();
            session.disconnect();

        } catch (Exception e) {
            e.printStackTrace();
        }
    }

    public static void main(String[] args) {
        // Usage example
        deleteFile("remote_username", "remote_password", "remote_host", "/path/on/remote/node/file.pdf");
    }
}

Note: This example uses password authentication for simplicity, but in a production environment, you should use key-based authentication for better security. Also, the above code does not include error handling for session connection issues or command failures.

2. Remote Management Tools:

If you're using a cloud service or a remote management tool that has an API, you can use that to manage files on the remote node. For example, if your Selenium Grid is part of a cloud testing service, they might provide an API for file management.

3. File Transfer and Deletion Script:

If you have a file transfer system in place to retrieve the file from the remote node, you could extend that system with a script to delete files after transfer. For example, a script on the remote node could monitor a directory and delete files that are older than a certain threshold or after they've been transferred.

4. Automation Server:

If the remote node is orchestrated by an automation server like Jenkins, you could configure a job or add a post-build step to delete the downloaded files after your tests have finished.

5. Containerized Environments:

If your Selenium grid is running in a containerized environment (e.g., Docker, Kubernetes), you could simply dispose of the container after the tests are completed. This would remove the container's filesystem and all downloaded files with it.

Remember that for methods 1, 3, and 4, you must have the necessary permissions to run deletion commands on the remote system, and you should be very careful to target only the intended files to avoid accidental data loss.
