Feature: Issue #96: Sub-steps failed without any error info to help debug issue
. I am trying to run execute_steps. One of them fails, but the error output
. from behave has no details whatsoever. It is virtually impossible
. to figure out why it failed. as no error output is present except the
. final error message
.
. def before_scenario(context,scenario):
. context.execute_steps(u'''
. When "admin:admin" sends POST "/tasks/testStart"
. Then I expect HTTP code 200
. ''')
.
. File ".../behave/runner.py", line 262, in execute_steps
. assert False, "FAILED SUB-STEP: %s" % step
. AssertionError: FAILED SUB-STEP: When "admin:admin" sends POST "/tasks/testStart"
.
. All we get is the "sub-step failed" but no info whatsoever
. as to why it failed...
