Not every system under test can be run with long names, and this makes
rebar's common_test support useless in those environments, as it
currently uses long names (test@hostname.domain) by default, without
recourse to change them.
This patch adds support for a {ct_use_short_names, boolean()} config
variable, which allows the user to specify whether short or long names
are required.
This patch allows users to specify the directory in which common_test
source files can be found. Most common_test suites are integration,
rather than unit tests and keeping the sources apart from test sources
for other frameworks such as eunit and PropEr is a useful feature.
This change adds support for executing ct test runs based on test
specificiations, which was missing previously. The rebar_ct module
now looks for any number of files with a name ending in `test.spec`
and if it finds one or more, passes these after the `-spec` argument
to ct_run instead of explicitly configuring the config, user config
and coverage config variables.
When no specifications are found, then the module behaves as it did
before this change, and both the ct1 and (new) ct2 integration tests
appear to show this is a backwards compatible patch.
