Run python behave from python instead of command line

Question

Is there any way to run python behave from within python and not via command line?

default usage: run behave command in base folder with features/steps

desired usage: call a function (or have a certain import) which executes the behave tests in a specified folder

There appears to be example code right on the download page that imports it and runs it from a file: pypi.python.org/pypi/behave. In general, yes, if you can run it from command line, you can run it from a file — en_Knight

Maybe I don't see the obvious, but yes I started from the example - and they only start it with the command "behave". Could you please point me to where to they explain how to run it from a file? Thank you! — dreamflasher

Found the solution by working through the behave source code:

from behave.__main__ import main as behave_main
behave_main("path/to/specified/folder")

The main method of behave enumerates and processes all paths it finds in its arguments.

Example with additional arguments to add tag (-t) and prevent output of skipped scenarios (-k): behave_main(["path/to/tutorial", '-t @run', '-k'])

you may run a single feature file by specifying file path(absolute to relative) behave_main("/".join([str(main.ROOT_DIR.resolve()), "features/Sample_REST_API_Testing.feature"])) or behave_main("~/pythonp/python-bdd/features/Sample_REST_API_Testing.feature")

I had some errors with that approach (RecursionError: maximum recursion depth exceeded while calling a Python object) and found this works fine: from behave import main as behave_main behave_main.main(folder)
