…nnotations

Extend the option to specify a module based data fixture files to the
@magentoDataFixtureBeforeTransaction annotation.
Previously they where only available for the @magentoDataFixture annotation.

The syntax is the same:
@magentoDataFixtureBeforeAnnotation Foo_DataFixtureDummy::Test/Integration/foo.php

There is no backward compatibility break associated with this commit.
