Chris Jerdonek added the comment:
Here is a type of test case that I think should be considered for addition (to
confirm that the code doesn't double-convert strings in at least one case).
Maybe there is already a test case like this:
class MyString(str): pass
def convert(s):
return MyString("*" + s)
parser = ArgumentParser()
parser.add_argument("--test", dest="test", type=convert, default="foo")
args = parser.parse_args()
print(args.test)
