Feature: Rerun Formatter
To simplify to run the scenarios that have failed during the last test run
As a tester
I want that behave generates the necessary information for me.
. SOLUTION:
.
. Put RerunFormatter into "behave.ini" configuration file:
.
. # -- file:behave.ini
. [behave]
. format = rerun
. outfiles = rerun.txt
.
. Then a "rerun.txt" file is generated during each test run
. that contains the file locations of the failing scenarios, like:
.
. # -- file:rerun.txt
. # RERUN: Failing scenarios during last test run.
. features/alice.feature:10
. features/alice.feature:42
.
. To rerun the failing scenarios of the last test run, use:
.
. behave @rerun.txt
@setup
Scenario: Feature Setup
Given a new working directory
And a file named "features/steps/steps.py" with:
"""
from behave import step
@step('a step passes')
def step_passes(context):
