White Box Testing White-box testing is a testing technique 
which checks the internal functioning of the system. In this method, 
testing is based on coverage of code statements, branches, paths or 
conditions. White-Box testing is considered as low-level testing. It is 
also called glass box, transparent box, clear box or code base testing. 
The white-box Testing method assumes that the path of the logic in a 
unit or program is known.
Types of White Box 
Testing:
o Path Testing
