In computer programming, specifically when using the imperative programming paradigm, an assertion is a predicate (a Boolean-valued function over the state space, usually expressed as a logical proposition using the variables of a program) connected to a point in the program, that always should evaluate to true at that point in code execution.
assert.h is a header file in the C standard library. It defines the C preprocessor macro assert and implements runtime assertion in C. assert.h is defined in ANSI C as part of the C standard library. In the C++ programming language, assert.h and < cassert > are available; both are functionally equivalent. [1]
A basic example is in the argv argument to the main function in C (and C++), which is given in the prototype as char **argv—this is because the variable argv itself is a pointer to an array of strings (an array of arrays), so *argv is a pointer to the 0th string (by convention the name of the program), and **argv is the 0th character of the ...

Limited C++ set by design to keep usage easy and allow it to work on embedded platforms. C++ is buried in macros so the learning curve for C programmers is minimal. Ported to Symbian. Has a mocking support library CppUMock Criterion: Yes: Yes: Yes: Yes: Yes [49] MIT: Unit testing framework with automatic test registration. Supports theories and ...
Unit is defined as a single behaviour exhibited by the system under test (SUT), usually corresponding to a requirement [definition needed].While it may imply that it is a function or a module (in procedural programming) or a method or a class (in object-oriented programming) it does not mean functions/methods, modules or classes always correspond to units.
For 1., a natural language comment (like // m equals the maximum value in a[0...i-1] in the above example) is sufficient. For 2., programming language support is required, such as the C library assert.h, or the above-shown invariant clause in Eiffel. Often, run-time checking can be switched on (for debugging runs) and off (for production runs ...
September 2015) (Learn how and when to remove this message) A callback is often back on the level of the original caller. In computer programming , a callback is a function that is stored as data (a reference ) and designed to be called by another function – often back to the original abstraction layer .
