如何使用行为（Python BDD 框架）设置环境变量？

Question

So our test environments dynamically change depending on the release that we are working on.

For example:

• for abc release the URL for the test environment would be feature-abc.mycompany.com, for xyz release the URL for the test environment would be feature-xyz.company.com and so on so forth.
• Same thing would be for staging: release-abc.mycompany.com, release-xyz.mycompany.com, etc..
• Production is just static URL: platform.mycompany.com

With this being said, I need to specify on which URL I would like my tests to be executed using behave BDD framework for Python.

To be specific Im looking for the equivalent functionality that cucumber has for Ruby using: features/support/env.rb file to define multiple URL (qa, staging, production, etc) so that on the command-line (terminal) I would just say xyz (having qa = feature(the release).mycompany.com

Something like: How can I test different environments (eg development|test|production) in Cucumber?

Answer 1

behave-1.2.5 introduced the userdata concept.

behave -D BUILD_STAGE=develop …

Load the corresponding configuration for this stage in the before_all() hook.

Answer 2

Ok, so for this there is a Pull Request (PR #243) to be able to do this in behave's github repo.

In the meantime as a workaround they suggested me to use os.getenv('variable_name', 'default_value') , and then at the command line I would just say export variable_name='another_value' ; behave export variable_name='another_value' ; behave

Please see more detailed on this on our short thread:
