  White-box testing
  
  - This testing (also known as clear box testing, glass box testing, transparent box testing, and structural testing) is a method of testing software that tests internal structures or workings of an application, as opposed to its functionality (i.e. black-box testing).
  
  - In this testing an internal perspective of the system, as well as programming skills, are used to design test cases.
  
  - The inputs to exercise paths through the code and determine the appropriate outputs is done by the tester.
  
  - This is analogous to testing nodes in a circuit, e.g. in-circuit testing (ICT).
  
  - This testing can be applied at the unit, integration and system levels of the software testing process.
  
  - Although traditional testers tended to think of this testing as being done at the unit level, it is used for integration and system testing more frequently today.
  
  - It can test paths within a unit, paths between units during integration, and between subsystems during a system–level test.
  
  - Though this method of test design can uncover many errors or problems, it has the potential to miss unimplemented parts of the specification or missing requirements.
  
  - White-box test design techniques include the following code coverage criteria:
  
  1. Control flow testing
  2. Data flow testing
  3. Branch testing
  4. Statement coverage
  5. Decision coverage
  6. Modified condition/decision coverage
  7. Prime path testing
  8. Path testing
