Test coverage refers to the percentage of software requirements that are tested by black-box testing for a system or application. [7] This is in contrast with code coverage, which examines the inner workings of a program and measures the degree to which the source code of a program is executed when a test suite is run. [8]
Java code coverage tools are of two types: first, tools that add statements to the Java source code and require its recompilation. Second, tools that instrument the bytecode, either before or during execution. The goal is to find out which parts of the code are tested by registering the lines of code executed when running a test.

The term "black box" is used because the actual program being executed is not examined. In computing in general, a black box program is one where the user cannot see the inner workings (perhaps because it is a closed source program) or one which has no side effects and the function of which need not be examined, a routine suitable for re-use.
White-box testing (also known as clear box testing, glass box testing, transparent box testing, and structural testing) is a method of software testing that tests internal structures or workings of an application, as opposed to its functionality (i.e. black-box testing). In white-box testing, an internal perspective of the system is used to ...
A black-box fuzzer [37] [33] treats the program as a black box and is unaware of internal program structure. For instance, a random testing tool that generates inputs at random is considered a blackbox fuzzer. Hence, a blackbox fuzzer can execute several hundred inputs per second, can be easily parallelized, and can scale to programs of ...
As its name implies, BlackBox Component Builder supports blackbox abstractions and reuse, in contrast to whitebox, as defined in the book Component Software by Szyperski. [6] [7] In 1993, it was released as Oberon/F [8] [9] [10] (for Oberon Framework) and was renamed to BlackBox Component Builder with release 1.3 end of the 1990s.
Gray-box testing is beneficial because it takes the straightforward technique of black-box testing and combines it with the code-targeted systems in white-box testing. Gray-box testing is based on requirement test case generation because it presents all the conditions before the program is tested by using the assertion method.
