Context: I am using Python with Behave (BDD).
Whether I run my tests from the command line (behave) or from a custom main(), the behavior is the same: the test runs and the only output that I see in the console is the standard BDD report.
My tests include print() statements that help me debug my code. However, none of these print statements are being displayed in the console output when I run behave.
Is there any way we can have "behave" display the print statements in our code?
My Main()
config = Configuration()
if not config.format:
default_format = config.defaults["default_format"]
config.format = [ default_format ]
config.verbose = True
r = runner.Runner(config)
r.run()
if config.show_snippets and r.undefined_steps:
print_undefined_step_snippets(r.undefined_steps)
My test.feature file:
Feature: My test feature with the Behave BDD
Scenario: A simple test
Given you are happy
When someone says hi
Then you smile
My test_steps.py file:
from behave import given, when, then, step, model
@given('you are happy')
def step_impl(context):
pass
@when ('someone says {s}')
def step_impl(context, s):
context.message = s
print("THIS IS NEVER DISPLAYED IN THE CONSOLE")
pass
@then ('you smile')
def step_impl(context):
assert(context.message == "hi")
I figured it out after spending more time reading the documentation. It is actually quite simple. By default, behave does not display any output (i.e. by using print()) unless there is a failure in the test.
To force displaying all output regardless of the outcome of the test (pass/fail), all you need is to change some of the default settings. The easiest way to achieve that is to create a file named behave.ini in the root of your project's directory and put the following:
Filename: behave.ini
[behave]
stderr_capture=False
stdout_capture=False
Next time you run your behave tests, you will see all outputs from your debug statements whether your tests pass or fail.
