I need the app I am testing to read command line switches and options

[FriesK1]

I am writing a library that will handle our configuration management. Part of what I need to test is setting those options from the command line... its a standard part of input for this library and critical for a properly tested package. So is there a mechanism to send command line switches not to behave, but to the package behave is testing? This is a pretty critical piece of testing for most programs I write.

Can you describe the way you'd like to use Behave to test the CLI behavior of your application?

It really depends on that. Behave is just a test runner. How you implement your tests is a different story.

For example, you may want to take a look at cli-test-helpers for ready-to-use test setups if you're fine to run unit tests. You can use the ideas to test a CLI from there too, and use (nearly) the same test code in your step implementations, if you prefer to stick to Behave.

@FriesK1

• Have you looked at behave4cmd0 and its step-library (bundled with behave) ?
• There are some similar behave step-libraries for command-process on https://pypi.org/ (AFAIK).
  HINT: Just search for behave .

SEE ALSO:

• Bundled behave4cmd0: https://github.com/behave/behave/blob/main/behave4cmd0/
  HINT: Look at *_steps.py Python modules for step-library functionality.
• behave4cmd0 in own repo (WIP): https://github.com/behave/behave4cmd0
  NOTE: There may be some setup steps need to be able to use it (setup where the root-directory is).
