Process steps for a happy path are also used in the context of a use case. In contrast to the happy path, process steps for alternate flow and exception flow may also be documented. [3] Happy path test is a well-defined test case using known input, which executes without exception and produces an expected output. [4]
Examples that are common outside professional programming circles include: Using spreadsheet lookup functions to replicate the functionality of a database; Using variant data types as loop counters in Microsoft Visual Basic where an integer type is also available.
In computer programming and software design, code refactoring is the process of restructuring existing source code—changing the factoring—without changing its external behavior. Refactoring is intended to improve the design, structure, and/or implementation of the software (its non-functional attributes), while preserving its functionality .
A low-level programming language is one like assembly language that contains commands closer to processor instructions. In formal methods , a high-level formal specification can be related to a low-level executable implementation (e.g., formally by mathematical proof using formal verification techniques).
In this way, a program can execute chains or groups of functional objects, while safely decoupled from having any direct reference to the enclosing host object. Phone numbers are an excellent analog and can easily illustrate the degree of this decoupling. For example, some entity provides another with a phone number to get a particular job done.
According to the authors of Design Patterns, there are two key elements to an anti-pattern that distinguish it from a bad habit, bad practice, or bad idea: . The anti-pattern is a commonly-used process, structure or pattern of action that, despite initially appearing to be an appropriate and effective response to a problem, has more bad consequences than good ones.
Third, the decompilation process must, if possible, be confined to the parts of the target program relevant to interoperability. Since one of the purposes of decompilation is to gain an understanding of the program structure, this third limitation may be difficult to meet. Again, the burden of proof is on the decompiler.
Flow diagram. In computing, serialization (or serialisation, also referred to as pickling in Python) is the process of translating a data structure or object state into a format that can be stored (e.g. files in secondary storage devices, data buffers in primary storage devices) or transmitted (e.g. data streams over computer networks) and reconstructed later (possibly in a different computer ...
