If we use SCOPED_TRACE we have an additional line for the scope in the error message.
It would be great if this could be integrated into the StackTrace formatting.

I added some senseless examples just to have some examples:

void checkValues( std::vector const& expectedValues, std::vector const& resultValues )
{
ASSERT_EQ( expectedValues.size(), resultValues.size() );
for ( size_t i=0; i<expectedValues.size(); ++i )
{
SCOPED_TRACE( "Checking index " + std::to_string( i ) );
EXPECT_EQ( expectedValues.at(i), resultValues.at(i) );
}// for
}
TEST( TestMath, ScopedFailures )
{
std::vector expected;
expected.push_back( 1 );
expected.push_back( 2 );
expected.push_back( 3 );
expected.push_back( 4 );
expected.push_back( 5 );
std::vector results;
results.push_back( 1 );
results.push_back( 1 );
results.push_back( 3 );
results.push_back( 3 );
results.push_back( 3 );
checkValues( expected, results );
}

results2.push_back( 1 );
results2.push_back( 2 );
results2.push_back( 3 );
results2.push_back( 5 );
results2.push_back( 6 );
{
SCOPED_TRACE( "Check first results");
checkValues( expected, results );
}
{
SCOPED_TRACE( "Check second results");
checkValues( expected, results2 );
}
}
