And to save all other people's sanity ;-) you could introduce a macro  
like this:

#define EXPECT_SAME_SIZEOF_WITH_AlignedCharArray(A) \
     EXPECT_EQ(sizeof(A), sizeof(AlignedCharArray<A>::union_type))

and then

EXPECT_SAME_SIZEOF_WITH_AlignedCharArray(char)
EXPECT_SAME_SIZEOF_WITH_AlignedCharArray(char[1])
EXPECT_SAME_SIZEOF_WITH_AlignedCharArray(char[2])
EXPECT_SAME_SIZEOF_WITH_AlignedCharArray(char[3])
EXPECT_SAME_SIZEOF_WITH_AlignedCharArray(char[4])
EXPECT_SAME_SIZEOF_WITH_AlignedCharArray(char[5])
