how could i add argument to robot lin command or how to create my own robot command

[hicham kharro]

Goodmornning ,

Well my problem is that, i’m looking for a way to add an author argument to robot line command and to model it to my project. An example of what I want to do :

Robot –u  unitary_test  --include tag1 tag2 tag3 –exclude tag4 tag7  --file_log=c:\file_log    / functionality  /subfonctionality

Your example is a bit unclear. What do you mean by an "author argument"? Have you considered simply setting variables or metadata from the command line with the --variable and --metadata arguments?

That being said, it's pretty easy to write your own custom test runner script that wraps robot/pybot. To avoid clashing with robot arguments, you might want to prefix all of your custom arguments with "+" or some other character. The argparse module makes this pretty easy.  Then, build up a new argument list based on what you parsed and didn't parse, and then pass it to robot.

Here's a really basic example that lets you specify "+f" or "++firefox" to run with firefox (or more accurately, it sets the ${BROWSER} variable to "firefox"):

import argparse

from robot import run_cli

parser = argparse.ArgumentParser(prefix_chars="+")

parser.add_argument("+f", "++firefox", action="store_true",

                    help="use firefox")

args, remaining_args = parser.parse_known_args()

# hard-code some arguments:

new_args = ["--outputdir", "./results"]

# translate custom arguments into something pybot understands

if args.firefox:

    new_args.extend(["--variable", "BROWSER:firefox"])

else:

    new_args.extend(]"--variable", "BROWSER:chrome"])

# run with our new arguments and all the remaining arguments

run_cli(new_args + remaining_args)

Hi,

Didn't know argparse supports parsing only some of the arguments. Very
nice, thanks for sharing Bryan!

One note to those trying Bryan's example: `run_cli` exits Python
interpreter with `sys.exit(rc)`, so you need to catch the resulting
`SystemExit` if you want to do any actions after test execution. The
general pattern is like this:

try:
run_cli(args)
except SystemExit as exit:
# cleanup code here
sys.exit(exit.code) # exit with robot's original return code


Cheers,
