I have have a bunch of configuration items stored inside my projects Config.ini file which looks like this: I have a project that has been implemented using a mix of python and Robotframework scripts. """ expected = float ( expected ) actual = _ble_read_setpoint () robot. :param expected: the expected setpoint value info ( 'Change temperature setpoint to %f' % value ) _ble_send_setpoint ( value ) def check_temperature_setpoint ( expected ): """Function exposed as a keyword to check the temperature setpoint.

Import import # Variable that is supposed to be in the fridge firmware Here is an example of a Python library that is ready to be imported in Robot Framework. Instead, you should write a wrapper library to expose nice keywords, as suggested in this discussion on stackoverflow. if you already have a custom Python library (like me), you probably don't want to directly import it in Robot Framework.A Python function named input_credentials() can be used in Robot Framework as Input Credentials, input credentials, Input credentials or even input_credentials (it's up to you).Python functions with a leading _ in their names are hidden in Robot Framework. Keywords report failures with exceptions, log by writing to standard output and can return values using the return statement. Keywords also take the same arguments as the methods implementing them. The simplest approach is having a module (in Python) or a class (in Python or Java) with methods which map directly to keyword names. It's called " Static API" in the documentation: It is the one I used for my actual project and the one I will present here. The simplest solution is sufficient in most cases. In fact, there are several ways to call Python code from Robot Framework. I ended watching YouTube videos of live coding from an Indian consulting company. Clearly, it's more a Reference Manual than a Getting Started. The official documentation is very detailed, but may be hard to comprehend at first sight. I must admit that my first attempts to use my existing Python library in Robot Framework were quite laborious. Its capabilities can be extended by libraries implemented with Python or Java. On the Robot Framework's official page, we can read: How I can create trully new keywords, like keywords to establish a Bluetooth connection to a fridge and send it a new temperature setpoint? Here, I am simply reusing existing keywords. Pip is the easiest way to install it as all the packages are available on PyPi:Įnter fullscreen mode Exit fullscreen mode Robot Framework is mainly written in Python and the source code is available on GitHub. The framework was initially developed at Nokia Networks and was open sourced in 2008. Robot Framework itself is open source software released under Apache License 2.0, and most of the libraries and tools in the ecosystem are also open source. It can be used for test automation and robotic process automation (RPA). Robot Framework is a generic open source automation framework. I will let Robot Framework introduce itself: In this article, I will explain how you can interface Robot Framework and a custom Python library in order to write automated tests for a connected frige (which is fictitious, I hope you got it). Needless to say that I was far from connecting to my frige over Bluetooth. There are a lot of tutorials for Robot Framework on the Internet, but most of them teach you how to connect to a web page to enter your login and password, or to use a REST API to perform 2+2=4 (and I am not exagerating that much □). "You should try Robot Framework, it seems promising!" I have a Python library that handles everything! Now, I would like to write tests for it." "The Bluetooth communication between our connected frige and our PC-based software is gettting better and better. Here is a story based on my professionnal life:
