如何在behave(BDD)中查看print（）语句

Question

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)

我的test.feature文件：

Feature: My test feature with the Behave BDD
    Scenario: A simple test
    Given you are happy
    When someone says hi
    Then you smile

我的test_steps.py文件：

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")

在命令行中，您可以使用以下命令：

--no-capture，用于立即打印任何stdout输出。

--no-capture-stderr用于立即打印任何stderr输出。
