# This script tests nothing (except the fact that modules load w/o warnings).
# However, it tries to load them all.
# This means that untested modules would also be included into
# code coverage summary, lowering total coverage to its actual value.

# I.e. having a well-covered module and a totally uncovered one will result
# in 50% coverage which is probably closer to truth.

If we want to convert svn repository to git we do next:
````
git svn clone --authors-file=authors.txt --no-metadata  http://vcs/svn/ESB/ESB.Report/trunk ESB.Report
````
after that we got the following link:

````
git@server.main.mycompany.ru:ESB/esb-creport.git
````
than we create repository in git (gitlab):
