Output Test names in unittest discover

I'm running Python unittest using the discover mode:
% python -m unittest discover
The system prints a dot for each test, but I'd rather see a test name.
Is there an option that makes this happen?

The verbose flag (-v) is what you're looking for:
$ python -m unittest discover -v
test_a (tests.test_a.TestA) ... ok
test_b (tests.test_b.TestB) ... ok
...
For more options, check:
$ python -m unittest --help
usage: python -m unittest [-h] [-v] [-q] [--locals] [-f] [-c] [-b]
[tests [tests ...]]
positional arguments:
tests a list of any number of test modules, classes and test
methods.
optional arguments:
-h, --help show this help message and exit
-v, --verbose Verbose output
-q, --quiet Quiet output
--locals Show local variables in tracebacks
-f, --failfast Stop on first fail or error
-c, --catch Catch Ctrl-C and display results so far
-b, --buffer Buffer stdout and stderr during tests
...

How to override the cli name in argparse -h usage information?

I am bundling my python app into an .AppImage file. Now, when I run it with flag -h I would expect it to print something along these lines:
$ ./mytool.AppImage -h
usage: mytool [-h] [-d DIR] [-f] [-e] [BLA [BLA ...]]
...
But due to the nature of the AppImage bundling process I get:
$ ./mytool.AppImage -h
usage: AppRun [-h] [-d DIR] [-f] [-e] [BLA [BLA ...]]
...
That is, AppRun instead of mytool.
So my question is:
How can I force override the app name so that regardless of how the app is called it will always print the same name in the usage string?

As per hpaulj's comment, this can solved by simply setting the prog parameter of the argparse.ArgumentParser constructor:
parser = argparse.ArgumentParser(
prog='mytool',
description='Some description...'
)

Python: ArgParse with a Main command and Sub command

Hi I'm using ArgParse to handle my arguments. I would like the code to work like this
# Main function
$ myApp -i INPUT -o OUTPUT -s STUFF
# Configure function
$ myApp config -a conf1 -b conf2
import argparse
from argparse import RawTextHelpFormatter
parser = argparse.ArgumentParser(description='myApp',formatter_class=RawTextHelpFormatter)
parser.add_argument('-i',help='input',required=True)
parser.add_argument('-o',help='output',required=True)
parser.add_argument('-s',help='stuff',default=None,required=False)
args = parser.parse_args()
subp = parser.add_subparsers()
conf_parser = subp.add_parser('config', help='configure')
conf_parser.add_argument('-a',help='a config file',default=None,required=False)
conf_parser.add_argument('-b',help='b config file',default=None,required=False)
conf_args = conf_arser.parse_args()
Here's the output
python sandbox/test1.py --help
usage: test1.py [-h] -i I -o O [-s S]
myApp
optional arguments:
-h, --help show this help message and exit
-i I input
-o O output
-s S stuff
I'm not getting the config args to show. I'm not sure what I'm doing wrong here.
Thanks!

Solved it
import argparse
from argparse import RawTextHelpFormatter
parser = argparse.ArgumentParser(description='myApp',formatter_class=RawTextHelpFormatter)
parser.add_argument('-i',help='input',required=True)
parser.add_argument('-o',help='output',required=True)
parser.add_argument('-s',help='stuff',default=None,required=False)
subp = parser.add_subparsers(help='configure')
conf_parser = subp.add_parser('config')
conf_parser.add_argument('-a',help='a config file',default=None,required=False)
conf_parser.add_argument('-b',help='b config file',default=None,required=False)
args = parser.parse_args()
python sandbox/test1.py --help
usage: test1.py [-h] -i I -o O [-s S] {config} ...
myApp
positional arguments:
{config} configure
optional arguments:
-h, --help show this help message and exit
-i I input
-o O output
-s S stuff
python sandbox/test1.py config --help
usage: test1.py config [-h] [-a A] [-b B]
optional arguments:
-h, --help show this help message and exit
-a A a config file
-b B b config file

--help for a selected command line argument

Is it possible to get --help message for a selected argument in command prompt?
Example:
python my_program.py -h in cmd will provide the whole help message.
Say my_program.py takes 2 cmdline argument -a and -b. Can I get the --help message of -a alone?
Something like this, python my_program.py -h -a. Is that possible?

Python argparse: Mutually exclusive required group with a required option

I am trying to have a required mutually exclusive group with one required parameter. Below is the code which I have put
#!/usr/bin/python
import argparse
import sys
# Check for the option provided as part of arguments
def parseArgv():
parser = argparse.ArgumentParser()
group = parser.add_mutually_exclusive_group()
group.add_argument("-v", "--verbose", choices=[1,2,3,4],
help = "Increase verbosity")
group.add_argument("-q", "--quiet", action="store_true", help = "Run quietly")
name = parser.add_mutually_exclusive_group(required=True)
name.add_argument("-n", "--name", help = "Name of the virtual machine")
name.add_argument("-t", "--template", help = "Name of the template to use \
for creating vm. If path is not provided then it will be looked \
under template directory.")
parser.add_argument("-s", "--save", help = "Save the machine template. If \
path is not provided then it will be saved under template directory.");
#parser.add_argument("-k", "--kick_start", required = True, help = "Name of the \
# kick start file. If path is not provided then it will be look into http \
# directory.")
if len(sys.argv) == 1:
parser.print_help()
args = parser.parse_args()
if __name__ == '__main__':
parseArgv()
Now the output of this program as follow
$ python test.py
usage: test.py [-h] [-v {1,2,3,4} | -q] (-n NAME | -t TEMPLATE) [-s SAVE]
optional arguments:
-h, --help show this help message and exit
-v {1,2,3,4}, --verbose {1,2,3,4}
Increase verbosity
-q, --quiet Run quietly
-n NAME, --name NAME Name of the virtual machine
-t TEMPLATE, --template TEMPLATE
Name of the template to use for creating vm. If path
is not provided then it will be looked under template
directory.
-s SAVE, --save SAVE Save the machine template. If path is not provided
then it will be saved under template directory.
usage: test.py [-h] [-v {1,2,3,4} | -q] (-n NAME | -t TEMPLATE) [-s SAVE]
test.py: error: one of the arguments -n/--name -t/--template is required
But if I un-comment the from line 20 - 22 then the output change as below
$ python test.py
usage: test.py [-h] [-v {1,2,3,4} | -q] (-n NAME | -t TEMPLATE) [-s SAVE] -k
KICK_START
optional arguments:
-h, --help show this help message and exit
-v {1,2,3,4}, --verbose {1,2,3,4}
Increase verbosity
-q, --quiet Run quietly
-n NAME, --name NAME Name of the virtual machine
-t TEMPLATE, --template TEMPLATE
Name of the template to use for creating vm. If path
is not provided then it will be looked under template
directory.
-s SAVE, --save SAVE Save the machine template. If path is not provided
then it will be saved under template directory.
-k KICK_START, --kick_start KICK_START
Name of the kick start file. If path is not provided
then it will be look into http directory.
usage: test.py [-h] [-v {1,2,3,4} | -q] (-n NAME | -t TEMPLATE) [-s SAVE] -k
KICK_START
test.py: error: argument -k/--kick_start is required
But I want that either -n / -t along with -k become mandatory. How to achieve the same.

You have already achieved it! Argparse only prints the first error it finds, so while it may look like it's only checking -k, it actually recuires -n/-t too. You can see this by actually giving it the -k argument.
If you provide the -k argument, the error message will change from test.py: error: argument -k/--kick_start is required to test.py: error: one of the arguments -n/--name -t/--template is required.
