A parallel executor for Robot Framework tests. With Pabot you can split one execution into multiple and save test execution time.

Supported by Reaktor.

My goal in creating this tool is to help you guys with big test sets. I've worked with a number of teams around the world that were doing test execution time optimisation before I created this tool. I saw similarities in how Robot Framework testing systems have been built and came up with a quite good solution for the basic parallelisation problem. I hope this tool brings you joy and speeds up your test execution!

From PyPi:

 pip install -U robotframework-pabot

OR clone this repository and run:

 setup.py  install

• Pabot will split test execution from suite files and not from individual test level.
• In general case you can't count on tests that haven't desinged to be executed parallely to work out of the box when executing parallely. For example if the tests manipulate or use the same data, you might get yourself in trouble (one test suite logs in to the system while another logs the same session out etc.). PabotLib can help you solve these problems of concurrency. Also see TRICKS for helpful tips.

Supports all Robot Framework command line options and also following options (these must be before normal RF options):

--verbose
more output from the parallel execution

--command [ACTUAL COMMANDS TO START ROBOT EXECUTOR] --end-command
RF script for situations where pybot is not used directly

--processes [NUMBER OF PROCESSES]
How many parallel executors to use (default max of 2 and cpu count)

--pabotlib
Start PabotLib remote server. This enables locking and resource distribution between parallel test executions.

--pabotlibhost [HOSTNAME]
Host name of the PabotLib remote server (default is 127.0.0.1) If used with --pabotlib option, will change the host listen address of the created remote server (see https://github.com/robotframework/PythonRemoteServer) If used without the --pabotlib option, will connect to already running instance of the PabotLib remote server in the given host. The remote server can be started with: python PabotLib.py <path_to_resourcefile> python PabotLib.py resource.txt 192.168.1.123 8271 This enables sharing a resource with multiple Robot Framework instances

--pabotlibport [PORT]
Port number of the PabotLib remote server (default is 8270) See --pabotlibhost for more information

--resourcefile [FILEPATH]
Indicator for a file that can contain shared variables for distributing resources. This needs to be used together with pabotlib option. Resource file syntax is same as Windows ini files. Where a section is a shared set of variables.

--argumentfile[INTEGER] [FILEPATH]
Run same suites with multiple argumentfile options. For example:

 --argumentfile1 arg1.txt --argumentfile2 arg2.txt

Example usages:

 pabot test_directory
 pabot --exclude FOO directory_to_tests
 pabot --command java -jar robotframework.jar --end-command --include SMOKE tests
 pabot --processes 10 tests
 pabot --pabotlibhost 192.168.1.123 --pabotlibport 8271 --processes 10 tests
 pabot --pabotlib --pabotlibhost 192.168.1.111 --pabotlibport 8272 --processes 10 tests

pabot.PabotLib provides keywords that will help communication and data sharing between the executor processes. These can be helpful when you must ensure that only one of the processes uses some piece of data or operates on some part of the system under test at a time.
