Introduction
Python programming language has a robotic framework that can use exterior libraries like selenium for internet testing. In this article, we will study taking a look at instances and a variety of different terminologies associated with a robotic framework in python with a use case for the internet by trying out the use of the selenium library.
What Is The Robot Framework?
The robot framework is a customary open-source automation framework for acceptance testing, acceptance test-driven development, and robotic manner automation. It makes use of the keyword-driven trying-out method approach. The skills can be prolonged by taking a look at libraries that can be carried out through both Java and Python.
Acceptance Testing
It is a checking-out approach in which the functionality of a gadget is tested. The motive of acceptance checking out is to evaluate the skills of a machine by the enterprise requirements.
Acceptance Test-Driven Development
ATDD or acceptance test-driven improvement is an improvement methodology that is based totally on the conversation between enterprise customers, developers, and testers. They work in coordination and make acceptance checks in development to enforce the functionality.

Robotic Process Automation
RPA or robotic manner automation is the method of quite simply decreasing human effort in resonance with software program that makes use of desktop mastering and AI capabilities. RPA handles high-level repeatable tasks.
Robot Framework Architecture
The robotic framework is platform-independent, Although the core framework is applied with the use of python it can additionally run on JPython(JVM) and IronPython(.NET).
The take a look at facts is in an easy-to-edit structure when the system starts the framework strategies take a look at information and generate logs and reports. The interplay is treated by way of the libraries which can use extra check equipment as drivers to take a look at the target.
Installation
The advocated strategy to set up the robotic framework on python is to use the pip. You can use the following command to set up the framework.
pip set up a robot framework
Verifying Installation
After the profitable installation, you ought to be in a position to see each interpreter and robotic framework variations the usage of the -version option.
robot –version
reboot –version
Standard Libraries
The following takes a look at libraries that are dispensed with the robotic framework.
- Built-in
- Collections
- Date Time
- Dialogs
- Operating System
- Process
- Remote
- Screenshot
- String
- Telnet
- XML
Built-in Tools
In addition to the core check execution engine, there is some assisting equipment that is built into the robotic framework. The following built-in equipment is current in the robotic framework in python.
- Robot
- Libdoc
- Testdoc
- Tidy
Robot framework check records are described in one-of-a-kind sections listed below.
Test Cases
The take look instances can be classified in the following tests.
Workflow Tests
The robot framework takes a look at instances that are usually written in tabular syntax. Let us take a seem at the instance to recognize this.
- Users can create an account and log in
- Users can’t log in with an awful password
The robotic framework in python follows the take a look at instances to be written in easy English language instead of computerized take a look at cases. It follows a keyword-driven strategy that resonates with herbal language in phrases of moves and expectations.
The look at instances is built with key phrases and feasible arguments.
Higher-Level Tests
Take a look at instances in the robotic framework that can be developed with solely high-level key phrases and no positional arguments. Let us take a seem to be at an instance under to recognize high-level tests.
Data-Driven Tests
The data-driven assessments permit the variety of taking a look at statistics besides duplicating the workflow. The [Template] putting in the robotic framework units the take a look at case into a data-driven test.
Keywords
The check instances in the robotic framework are created with key phrases that come from two sources.
- Library Keywords
- User Keywords
Library Keywords
All the lowest degree key phrases are described in the popular libraries that can be carried out the usage of programming languages like Python, Java, etc.
The robotic framework comes with taking a look at libraries that can be divided into standard, external and customized libraries. Standard libraries are in the core framework such as built-in, screenshots, Operating systems, etc. External libraries are set up separately, like the selenium library for internet testing.
To use the key phrases in the library, library settings have to be imported. Let us take a seem at an instance to apprehend this.
User Keywords
One of the effective points of the robotic framework is that we can make customized high-level key phrases with the usage of different keywords. Let’s take a appear at an instance to recognize how it works.
User-defined key phrases can encompass moves supplied using different user-defined key phrases or library key phrases as well.
Variables
The variables are a very vital section of any take a look at the case in a robotic framework. Any information in the check case that is challenged to variability or exchange has fine described the usage of a variable.
Let us take a appear at how we can outline variables in a check case.
Using Variables
We can use the variables somewhere in the check case, they are most usually used as arguments in the keywords. Let us take an appearance at the instance to apprehend this.
Now that we know, how we can make a check case the use of the key phrases and variables. Let us work hard to understand how we would construct the check cases.
Organizing Test Cases
Robot check instances are created by taking a look at case files, however, we can prepare them into directories that create a take a look at suite hierarchy.
Collections of taking a look at instances are referred to as a take a look at suite. Every file that consists of the take a look at instances additionally varieties a check suite. It is feasible to arrange the check instances in a hierarchy of the usage of the directories, all these directories create high-level take a look at suites that get their title from listing names.
Setups and Teardowns
If you favor a particular keyword in a take a look at to be achieved earlier than or after, you can use the “Test Setup” and “Test Teardown” settings in the settings table. You can additionally use “Suite Setup” and “Suite Teardown” to execute key phrases earlier than or after in a check suit as well.
You can additionally create customized [Setup] and [Teardown] in a check case simply like [Template]. Let us take a seem to be at an instance to recognize this.
Using Tags
The robotic framework lets in tags to provide the take a look at instances of free metadata. The tags can be set in a file with the use of “Force Tags” and “Default Tags”.
It is viable to provide tags for a single check case the usage of [Tags] simply like [Template]. Let us take an instance to apprehend how we use tags.
After the execution, the document will have tags with take a look at instances related to them and information primarily based on the tags.
Robot Framework-Selenium Library
The selenium library in the robotic framework is a net trying-out library that makes use of the selenium equipment internally. Selenium library works excellent with python 2.7, 3.4, and more recent versions. In addition to the preferred python interpreter, it works with Pippy and JPython barring IronPython.
Installation
To install the selenium library, we can comply with the standard strategy of the use of the pip in python. Use the following command to install the selenium library in python.
pip set up robot framework-selenium library
Browser Drivers
After the setup is entire you nevertheless want to deploy applicable drivers for the working structures and browsers that you prefer to use in the tests. The universal method is to deploy the browser driver like the Chrome driver for chrome however alternatively, you can use the device known as a Web driver manager.
It will discover today’s model when required, it will download all the links/files in the proper location. It helps all principal running structures and helps to download browsers like chrome, opera, etc.
You can use the following command to deploy Web driver Manager
pip installation web driver manager
web driver manager Firefox chrome –link path /usr/local/bin
How To Use Selenium Library
To use the selenium library has to be imported the use of the “Library” putting as any different library. It is endorsed to use the robotic framework high-level key phrases to write the take a look at instances that use the selenium low-level key phrases internally.
Web Testing with Robot Framework and Selenium Library is an example of a use case.
In this example, we are going to make the following directories.
- application — it is an easy login software with a login page, welcome page, and an error page.
- tests — This will have all of the take a look at cases.
- tasks — This will have the tasks.
When the demo is running, you can execute the tests, the usage of the command
