Task Object Storage package.

Project description

Transaction management for Robot Framework RPA using MongoDB.

Included are two packages: tos and TOSLibrary. The former is the actual task object storage implementation written in pure Python, without any Robot Framework dependencies. TOSLibrary is a Robot Framework keyword library built on top of tos. It is built as a lightweight dynamic proxy library, so all the changes in tos are immediately available in TOSLibrary keywords.

For full documentation see

Quickstart guide


  • MongoDB (version >4)
  • Python (version >3.6)


Test PyPi:

pip install --extra-index task-object-storage


You can import TOSLibrary into your Robot Framework suite with

*** Settings ***
Library  TOSLibrary  ${db_server}:${db_port}  ${db_name}

If you are using authentication in MongoDB, you can pass credentials:

*** Settings ***
Library  TOSLibrary  ${db_server}:${db_port}  ${db_name}  ${db_user}  ${db_passw}

Now the keywords are callable from Robot Framework.

This library instance can also be accessed inside Python keywords with

from robot.libraries.BuiltIn import BuiltIn


The keywords can be also called with:

BuiltIn().run_keyword("<keyword name>")

To use task object storage in Python without any Robot Framework dependencies you should use tos package directly:

from tos.task_object_storage import TaskObjectStorage

tos = TaskObjectStorage(

If db_user and db_passw are empty strings, TaskObjectStorage will default to using no authentication.

Available keywords

See the full API documentation.

Building a distribution package from source

Create a pip wheel package using



python bdist_wheel

and distribute the whl package found in the dist directory.

This local package can be installed with

pip install <package-name>.whl

To upload to PyPi:

twine upload --repository-url dist/* --verbose
