Welcome to the 5th article in Behave BDD series!
What you will Learn :
Add Python virtual environment to PyCharm IDE
Verify whether virtual env got successfully added or not
Add Gherkin Plugin to PyCharm
Verify whether Gherkin plugin got successfully added or not
Additional Note
Add Python Virtual Environment to PyCharm IDE
We will now see how to add the Python virtual environment (that we had created in previous tutorials) to PyCharm IDE. Before we do that, let us first activate the virtual environment that we had created. To do that, go to command line and execute below commands
Notice above that we see the virtual environment directory that we had created earlier venv_py3.
Execute below commands to activate the virtual environment
Next execute ‘where python’ command, you will see the path of virtual environment
Copy the above path
In your PyCharm, go to File > Settings
The below window comes up
On the left hand panel, expand the project and select Python Interpreter, as seen above. The right hand side section shows all the packages/libraries installed for a particular python interpreter. At the moment, the Python Interpreter that you see on right hand side is the default Python interpreter. As you can see, right now we don’t see ‘behave’ library that we had installed for our virtual environment.
To add our virtual env, click the gear icon that you see above
Click Add, the below window comes up
As seen above, select ‘Virtualenv Environment’ from the left hand side and select the radio button ‘Existing environment’ that you see on right hand side
Click 
Paste the path that we had copied earlier: C:\Users\DELL\AppData\Local\Programs\Python\Python37-32\Scripts\venv_py3\Scripts\python.exe
Click Ok, the same path will become visible below
Click Ok, the same path will become visible below.
You can also see the behave and selenium packages that we had installed earlier for this virtual environment
In the command prompt, execute the below command, you will see that the version number matches
Click Ok that yousee in the below window
We will come back to our project
Verify whether virtual env got successfully added or not
To verify, right click project > New >Python File
Enter any name.py
Hit Enter. The python file gets created
See below. We do see the recommendation for selenium library
Similarly
Similarly for behave
This is how you setup a custom virtual env in PyCharm.
Add Gherkin Plugin to PyCharm
We will now add the Gherkin Plugin to our PyCharm IDE.
To do that, go to File > Settings > Plugins > Search for Gherkin, see below
Click Install, the plugin gets installed
Click Apply and Ok
Verify whether Gherkin plugin got successfully added or not
Right click project > New > File
Type some name.feature
Hit Enter
The green colored cucumber like icon that you see implies that Gherkin plugin is installed, see below
We also get Gherkin keyword auto-suggestions
Further, we see blue color Gherkin keywords
So this is how we add Gherkin plugin to PyCharm IDE
Additional Note
Note that you can go to File > Settings > Expand Editor > Select Font > Enter desired font and desired size for your python code
After changing the size/font, click Apply/Ok
