Feature: Capture log output
As a tester
I want that log output is captured
But log-records are only shown when failures/errors occur
So that failure diagnostics are simplified
. SPECIFICATION:
. * log_capture mode is enabled per default
. * log_capture mode can be defined on command-line
. * log_capture mode can be defined in behave configuration file
. * In log_capture mode: Captured log-records are only shown if a scenario fails
.
. RELATED:
. * logcapture.*.feature
. * logging.*.feature
@setup
Scenario: Feature Setup
Given a new working directory
And a file named "features/steps/use_behave4cmd_steps.py" with:
