on second run, output is not printed on stdout

[idoroseman]

first run is ok, but after something is modified, the runner works but nothing is displayed on the terminal

[idoroseman]

sometimes I get "Unhandled exception in thread started by "

Hey @idoroseman, I can't reproduce this locally on my machine. Could you give me more information about your problem?

• What version of sniffer?
• Did you install pyinotify, pywin32, MacFSEvents?
• Are you running nose tests, pietists, etc.?

Steps to reproduce would be great!

Thanks, Jeff

Hi Jeff I'm using sniffer 0.3.3 running on mac, so MacFSEvents redericting stdout to a file, I can confirm the script is running I'm running "behave" using the following scent.py

from sniffer.api import * # import the really small API
import os, termstyle, sys

# you can customize the pass/fail colors like this
pass_fg_color = termstyle.green
pass_bg_color = termstyle.bg_default
fail_fg_color = termstyle.red
fail_bg_color = termstyle.bg_default

# All lists in this variable will be under surveillance for changes.
watch_paths = ['.', 'features/']


# this gets invoked on every file that gets changed in the directory. Return
# True to invoke any runnable functions, False otherwise.
#
# This fires runnables only if files ending with .py extension and not prefixed
# with a period.

@file_validator
def not_pyc_files(filename):
    ## should change to check .hgignore
    return not filename.endswith('.pyc') and not os.path.basename(filename).startswith('.')


# This gets invoked for verification. This is ideal for running tests of some sort.
# For anything you want to get constantly reloaded, do an import in the function.
#
# sys.argv[0] and any arguments passed via -x prefix will be sent to this function as
# it's arguments. The function should return logically True if the validation passed
# and logicially False if it fails.
#
# This example simply runs nose.

@runnable
def execute_behave(*args):
    from behave import configuration
    from behave import __main__

    # Adding my wanted option to parser.
    #configuration.parser.add_argument('-u', '--url', help="Address of your url")

    # command that run behave.  
    try:
        return  __main__.main()
    except SystemExit as x:
        print "found error {0}: {1}".format(x.code, x.message)
        return not x.code 
    except:
    print "Unexpected error:", sys.exc_info()[0]
        return 0

Hey @idoroseman,

execute_behave needs to make sure it returns True if the tests pass.

__main__.main() returns 0 if it succeeds, which is false.

Also, an alternative is to use subprocess to just call behave instead (don't forget to check the exit code).
