Thank you.

Yes that's what I am doing.

No, the C++ conversions are very easy (feel free to help ;-)):
#include "cppunit..."   =>   #include "gtest/gtest.h"
class X : public CppUnit::TestFixture  =>  class X : public ::testing:Test
CPPUNIT_ASSERT_MESSAGE(msg, condition)   =>   ASSERT_TRUE(condition) << msg
CPPUNIT_ASSERT_EQUAL(c1, c2)    =>   ASSERT_EQ(c1, c2)
CPPUNIT_FALSE(msg)   =>   FAIL() << msg
private:  =>  protected:
test methods move outside of class declaration and become
TEST_F(className, methodName) instead
CPPUNIT_TEST...() registrations disappear

but the problem is that tests themselves are wrong no matter what the
testing library. For example:
basegfx::tools::importFromSvgD( aPoly, aSvg );
won't compile, as importfromSvgD() requires 4 parameters now instead
of just 2 (as I explained in an earlier email, this was caused by
commit 1536730 on 2013-10-29 by alg).
