Feature: display the help text
Scenario: help
When I run "conc --help"
Then STDOUT contains:
"""
Conc runs commands concurrently and returns the first non-zero exit code it encounters.
Usage: conc [flags] [commands...]
Flags:
--error-on-output error if any command produces output
--help, -h this help text
--show=all show the output of all commands
--show=failed show the output of only failed commands
--stderr-to-stdout print stderr of commands to stdout
--version, -V show the version
Examples:
conc --show=failed "echo one" "echo two" "echo three"
This executes the following commands concurrently:
- echo one
- echo two
- echo three
If any of the commands exit with a non-zero exit code,
conc will print the output of the failed command
and return that exit code.
"""
And the exit code is 0
