SSHLibrary is a Robot Framework test library for SSH and SFTP. The project is hosted on GitHub and downloads can be found from PyPI.
SSHLibrary is operating system independent and supports Python 2.7 as well as Python 3.4 or newer. In addition to the normal Python interpreter, it also works with Jython 2.7.
The library has the following main usages:
- Executing commands on the remote machine, either with blocking or non-blocking behavior.
- Writing and reading in an interactive shell.
- Transferring files and directories over SFTP.
- Ensuring that files and directories exist on the remote machine.
See keyword documentation for available keywords and more information about the library in general.
For general information about using test libraries with Robot Framework, see Robot Framework User Guide.
The recommended installation method is using pip:
pip install --upgrade robotframework-sshlibrary
Running this command installs also the latest Robot Framework and paramiko
versions. The minimum supported paramiko version is 1.15.3
.
The --upgrade
option can be omitted when installing the library for the
first time.
With recent versions of pip
it is possible to install directly from the
GitHub repository. To install latest source from the master branch, use
this command:
pip install git+https://github.com/robotframework/SSHLibrary.git
Alternatively you can download the source distribution from PyPI, extract it, and install it using one of the following depending are you using Python or Jython:
python setup.py install jython setup.py install
A benefit of using pip is that it automatically installs paramiko and Cryptography modules (or PyCrypto if paramiko version < 2.0) that SSHLibrary requires on Python.
On Jython, SSHLibrary requires Trilead SSH JAR distribution. You need to download Trilead SSH JAR distribution and add it to CLASSPATH.
To use SSHLibrary in Robot Framework tests, the library needs to first be imported using the Library setting as any other library.
When using Robot Framework, it is generally recommended to write as
easy-to-understand tests as possible. The keywords provided by
SSHLibrary are pretty low level and it is typically a good idea to
write tests using Robot Framework's higher level keywords that utilize
SSHLibrary keywords internally. This is illustrated by the following example
where SSHLibrary keywords like Open Connection
and Login
are grouped
together in a higher level keyword like Open Connection And Log In
.
