Simplify SSH and SFTP Testing with SSHLibrary: A Comprehensive Guide for Robot Framework Users
If you’re looking to simplify your SSH and SFTP testing in the Robot Framework, SSHLibrary is the test library for you. SSHLibrary is a versatile library that allows you to execute commands on remote machines, interact with an interactive shell, transfer files, and ensure file existence on remote machines. In this article, we will provide a comprehensive guide on using SSHLibrary, complete with step-by-step instructions and examples.
Installation
To get started with SSHLibrary, you need to install it along with its dependencies. The recommended installation method is using pip:
pip install --upgrade robotframework-sshlibrary
This command will not only install SSHLibrary but also the latest Robot Framework, Paramiko, and SCP versions. Make sure you have a minimum supported Paramiko version of 1.15.3 and a minimum supported SCP version of 0.13.0.
Getting Started
Once SSHLibrary is installed, you can import it in your Robot Framework tests using the Library setting, just like any other library. It is important to note that while SSHLibrary provides low-level keywords for SSH and SFTP operations, it is generally recommended to use higher-level keywords that utilize SSHLibrary keywords internally. This makes your tests more readable and maintainable.
For example, instead of using SSHLibrary keywords like “Open Connection” and “Login” directly, you can create higher-level keywords like “Open Connection And Log In” that group these low-level keywords together:
“`
*** Settings ***
Library SSHLibrary
*** Test Cases ***
My Test Case
Open Connection And Log In ${HOST} ${USERNAME} ${PASSWORD}
…
“`
Key Features
SSHLibrary offers a range of features that make SSH and SFTP testing easier and more efficient:
- Executing commands: SSHLibrary allows you to execute commands on remote machines, either with blocking or non-blocking behavior. This is useful for running scripts or issuing commands on remote servers.
- Interactive shell: You can write and read in an interactive shell using SSHLibrary. This is particularly useful when you need to interact with a command-line interface on a remote machine.
- File transfer: SSHLibrary supports transferring files and directories over SFTP. This enables you to easily upload or download files to and from remote machines.
- File existence: With SSHLibrary, you can ensure that files and directories exist on remote machines. This is useful for verifying the presence of specific files or directories before running tests.
Use Cases
SSHLibrary is a versatile tool that can be used in various scenarios. Here are a few real-world examples:
- Deployment Automation: Use SSHLibrary to automate the deployment of your application to remote servers. You can execute deployment scripts, transfer application files, and ensure the existence of required files and directories.
- Configuration Management: With SSHLibrary, you can automate the configuration management of your servers. You can execute configuration scripts, modify configuration files, and verify the configuration status.
- Log Analysis: SSHLibrary allows you to retrieve log files from remote machines. You can analyze log files for errors or anomalies, facilitating troubleshooting and debugging.
