v. t. e. Test-driven development ( TDD) is a way of writing code that involves writing an automated unit-level test case that fails, then writing just enough code to make the test pass, then refactoring both the test code and the production code, then repeating with another new test case. Alternative approaches to writing automated tests is to ...
Design by contract ( DbC ), also known as contract programming, programming by contract and design-by-contract programming, is an approach for designing software . It prescribes that software designers should define formal, precise and verifiable interface specifications for software components, which extend the ordinary definition of abstract ...
A software development methodology is a framework that is used to structure, plan, and control the life cycle of a software product. Common methodologies include waterfall, prototyping, iterative and incremental development, spiral development, agile software development, rapid application development, and extreme programming.
Unit is defined as a single behaviour exhibited by the system under test (SUT), usually corresponding to a requirement. While it may imply it's a function or a module (in procedural programming) or a method or a class (in object-oriented programming) it doesn't mean functions/methods, modules or classes always correspond to units.
v. t. e. Coding conventions are a set of guidelines for a specific programming language that recommend programming style, practices, and methods for each aspect of a program written in that language. These conventions usually cover file organization, indentation, comments, declarations, statements, white space, naming conventions, programming ...
The differences between the two languages are more prominent than their similarities. Java has static typing, while JavaScript's typing is dynamic. Java is loaded from compiled bytecode, while JavaScript is loaded as human-readable source code. Java's objects are class-based, while JavaScript's are prototype-based.
In software engineering, a design pattern describes a relatively small, well-defined aspect (i.e. functionality) of a computer program in terms of how to write the code . Using a pattern is intended to leverage an existing concept rather than re-inventing it. This can decrease the time to develop software and increase the quality of the ...
Reference architecture. A reference architecture in the field of software architecture or enterprise architecture provides a template solution for an architecture for a particular domain. It also provides a common vocabulary with which to discuss implementations, often with the aim to stress commonality. A software reference architecture is a ...
