UnitTests: consider scripts in Custom/scripts/test and allow complete pathes

[bschmalhofer]

Currently test scripts in _ Custom/scripts/test_ can override corresponding test scripts in scripts/test . This is useful when a package overrides core functionality. I propose the enhancement that test scripts in Custom/scripts/test are found and executed even when there is no counterpart in scripts/test . This would allow a cleaner separation between addons and core.

Enhanced the scope of this issue. It would also be nice if regular pathes to script files and directories could be passed. This should also designed to work with command line expansion. It must be decided how to handle the Custom dir in these cases.

Examples:

• bin/otobo.Console.pl Dev::UnitTest::Run --test Loader
• bin/otobo.Console.pl Dev::UnitTest::Run --test script/test/Loader.t
• bin/otobo.Console.pl Dev::UnitTest::Run --directory Selenium
• bin/otobo.Console.pl Dev::UnitTest::Run --directory scripts/test/Selenium
