I am using python-behave for BDD testing, I have to pass an URL (e.g. www.abc.com) from command line.
$behave -u "www.abc.com"
To achieve this, I have read behave documentation but there are not enough materials as well as explanations given for setting up the behave.ini file. I am also not sure how behave.ini file helps me to pass an argument.
Can someone please tell me how I can setup command line parameters for behave?
Advertisements. Behave has a collection of command line arguments and it can also be outlined from the configuration files. The values set in the configuration files are used automatically, however, it can be overruled by the command line arguments.
Behave - InstallationFor Behave installation, we should have pip – the package installer for the Python language installed in our system. The pip is installed by default, if the Python version is greater than 2(upto 2.7. 9). We can also use the easy_install for the Behave installation.
You can parse the Python command line arguments in sys. argv without having to know the length of the list, and you can call the built-in len() if the number of arguments is needed by your program.
The suggested solutions above were needed in the past.
behave-1.2.5 provides a "userdata" concept that allows the user to define its data:
behave -D browser=firefox ...

Outdated answer, Currently supported itself as described by this answer.
No, it's not possible, because there is a parser
that is defined in configuration.py
file, and only allow defined options of it.
But if you want you can (by help of monkey patch !), just add your option same as other options to this parser
.
For do that, first create a file for example behave_run.py
and patch this parser
before running of behave
:
from behave import configuration
from behave import __main__
# Adding my wanted option to parser.
configuration.parser.add_argument('-u', '--url', help="Address of your url")
# command that run behave.
__main__.main()
And now if you run python behave_run.py --help
, you can see your new url
option:
$ python behave_run.py --help | grep url
-u URL, --url URL Address of your url
Now, you can run this behave_run.py
file like behave
file and pass your url argument too:
$ python behave_run.py --url http://google.com
And you can access this value of url
option with context.config.url
, for example in environment.py
file and then set it for use in other functions:
def before_all(context):
context.browser = webdriver.Firefox()
context.url = context.config.url
Note:
If you want to call python run_behave.py
as run_behave.py
from anywhere, add this line:
#!/usr/bin/env python
to first line of run_behave.py
and change mode of it to a executable file with chmod +x run_behave.py
and then copy this file to one location of your PATH
, for example in /usr/local/bin
with sudo mv run_behave.py /usr/local/bin/run_behave.py
