The testing in which code is checked is known as White Box Testing.

Here's why:

1. White Box Testing, also known as Clear Box Testing, Open Box Testing, Glass Box Testing, Transparent Box Testing, Code-Based Testing, or Structural Testing, is a method of software testing where the internal structure/design/implementation of the item being tested is known to the tester.

2. In this method, the tester chooses inputs to exercise paths through the code and determines the appropriate outputs. This is analogous to testing nodes in a circuit, e.g. in-circuit testing (ICT).

3. White Box Testing is the detailed investigation of internal logic and structure of the code. White box testing is also called glass testing or open box testing. In order to perform white box testing on an application, a tester needs to know the internal workings of the code.

4. The tester needs to have a look inside the source code and find out which unit/chunk of the code is behaving inappropriately.
