Command line option to include groups

[jhoffland]

Currently, it is possible to exclude groups in the configuration file. To run the tests in those groups, the command line option --group is available or another configuration file needs to be specified when running. As far as is known, there is no command line option to run all tests; the tests run by default and the tests that are excluded in the configuration file.

Feature request A command line option, e.g. --include-group, that makes it possible to add groups to the test run, that are not run by default.
