[DSL] Changed the test framework to Minitest and configured the reporter

Previously, the "test-unit" gem has been use as the test framework,
which caused the output to lack the test names, and only show the
"dot" report.

This patch switches the platform, changes the superclass for all the
tests to inherit from `Minitest::Test`, and adds assertions to be
compatible with `Test::Unit`.
