Which is better black box or white box testing?

Which is “better” – white or black box testing? Neither – they are both necessary and complementary. Early white box testing assures code functionality and makes later, higher level testing less time intensive. Thorough black box testing enhances end user experience.

What is the difference between black box and white box testing?

Black Box testing has the main goal to test the behavior of the software whereas White Box testing has the main goal to test the internal operation of the system. Black Box testing is focused on external or end-user perspective whereas White Box testing is focused on code structure, conditions, paths and branches.
