Robot Framework remote servers allow hosting test libraries on different processes or machines than Robot Framework itself is running on. This version is implemented in Python and supports also Jython (JVM) and IronPython (.NET). See remote library interface documentation for more information about the remote interface in general as well as for a list of remote server implementations in other programming languages.
This project is hosted in GitHub and downloads are available in PyPI.
The easiest installation approach is using pip:
$ pip install robotremoteserverAlternatively you can download the source distribution, extract it, and install it using:
$ python setup.py installThe remote server can be started by simply creating an instance of the server and passing a test library instance or module to it:
from robotremoteserver import RobotRemoteServer from mylibrary import MyLibrary RobotRemoteServer(MyLibrary())By default the server listens to address 127.0.0.1 and port 8270. See the next section for information how to configure them.
The remote server accepts following configuration parameters:
Argument Default Explanation host'127.0.0.1'Address to listen. Use '0.0.0.0'to listen to all available interfaces.port8270Port to listen. Use 0to select free port automatically.port_fileNoneFile to write port that is used. allow_stopTrueAllow/disallow stopping the server using Stop Remote Serverkeyword.
Address and port that are used are printed to the console where the server is started. Writing port to a file by using port_file argument is especially useful when the server selects a free port automatically. Other tools can then easily read the active port from the file. If the file is removed prior to starting the server, tools can also wait until the file exists to know that the server is up and running.
Example:
from robotremoteserver import RobotRemoteServer from mylibrary import MyLibrary RobotRemoteServer(MyLibrary(), host='10.0.0.42', port=0, port_file='/tmp/remote-port.txt', allow_stop=False)The remote server can be gracefully stopped using three different methods:
- Hitting
Ctrl-Con the console where the server is running. - Sending the process
SIGINT,SIGTERM, orSIGHUPsignal. - Using
Stop Remote Serverkeyword (unless explicitly disabled).
The remote server project contains an example that can be studied and also executed once the library is installed. The example is also included in the source distribution.
