RSpec
RSpec is a computer domain-specific language (DSL) (particular application domain) testing tool written in the programming language Ruby to test Ruby code. It is a behavior-driven development (BDD) framework which is extensively used in production applications. The basic idea behind this concept is that of test-driven development (TDD) where the tests are written first and the development is based on writing just enough code that will fulfill those tests followed by refactoring. It contains its owmocking frameworkthat is fully integrated into the framework based upoJMock The simplicity in the RSpec syntax makes it one of the popular testing tools for Ruby applications. The RSpec tool can be used by installing the rspec gem which consists of three other gems, namely rspec-core, rspec-expectation and rspec-mock. History RSpec was started as an experiment by Steven Baker in 2005 along with his team members Dave Astels, Aslak Hellesøy and David Chelimsky. Chelimsky was responsib ...

Capybara (software)
Capybara is a web-based test automation software that simulates scenarios for user stories and automates web application testing for behavior-driven software development. It is written in the Ruby programming language. Capybara can mimic actions of real users interacting with web-based applications. It can receive pages, parse the HTML and submit forms. Background and motivation During the software development process (especially in the Agile and Test-driven Development environments), as the size of the tests increase, it becomes difficult to manage tests which are complex and not modular. By extending the human-readable behavior-driven development style of frameworks such as Cucumber and RSpec into the automation code itself, Capybara aims to develop simple web-based automated tests. Anatomy of Capybara Capybara is a Ruby library (also referred to as a gem) that is used with an underlying web-based driver. It consists of a user-friendly DSL (Domain Specific Language) ...

Cucumber (software)
Cucumber is a software tool that supports behavior-driven development (BDD). Central to the Cucumber BDD approach is its ordinary language parser called Gherkin. It allows expected software behaviors to be specified in a logical language that customers can understand. As such, Cucumber allows the execution of feature documentation written in business-facing text. It is often used for testing other software. It runs automated acceptance tests written in a behavior-driven development (BDD) style. Cucumber was originally written in the Ruby programming language and was originally used exclusively for Ruby testing as a complement to the RSpec BDD framework. Cucumber now supports a variety of different programming languages through various implementations, including Java and JavaScript. There is a port of Cucumber to .NET called SpecFlow, now superseded by Reqnroll. Gherkin language Gherkin is the language that Cucumber uses to define test cases. It is designed to be non-technical a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Behavior Driven Development
Behavior-driven development (BDD) involves naming software tests using domain language to describe the behavior of the code. BDD involves use of a domain-specific language (DSL) using natural-language constructs (e.g., English-like sentences) that can express the behavior and the expected outcomes. Proponents claim it encourages collaboration among developers, quality assurance experts, and customer representatives in a software project. It encourages teams to use conversation and concrete examples to formalize a shared understanding of how the application should behave. BDD is considered an effective practice especially when the ''problem space'' is complex. BDD is considered a refinement of test-driven development (TDD). BDD combines the techniques of TDD with ideas from domain-driven design and object-oriented analysis and design to provide software development and management teams with shared tools and a shared process to collaborate on software development.

Cross-platform
Within computing, cross-platform software (also called multi-platform software, platform-agnostic software, or platform-independent software) is computer software that is designed to work in several Computing platform, computing platforms. Some cross-platform software requires a separate build for each platform, but some can be directly run on any platform without special preparation, being written in an interpreted language or compiled to portable bytecode for which the Interpreter (computing), interpreters or run-time packages are common or standard components of all supported platforms. For example, a cross-platform application software, application may run on Linux, macOS and Microsoft Windows. Cross-platform software may run on many platforms, or as few as two. Some frameworks for cross-platform development are Codename One, ArkUI-X, Kivy (framework), Kivy, Qt (software), Qt, GTK, Flutter (software), Flutter, NativeScript, Xamarin, Apache Cordova, Ionic (mobile app framework ...

Macro (computer Science)
In computer programming, a macro (short for "macro instruction"; ) is a rule or pattern that specifies how a certain input should be mapped to a replacement output. Applying a macro to an input is known as macro expansion. The input and output may be a sequence of lexical tokens or characters, or a syntax tree. Character macros are supported in software applications to make it easy to invoke common command sequences. Token and tree macros are supported in some programming languages to enable code reuse or to extend the language, sometimes for domain-specific languages. Macros are used to make a sequence of computing instructions available to the programmer as a single program statement, making the programming task less tedious and less error-prone. Thus, they are called "macros" because a "big" block of code can be expanded from a "small" sequence of characters. Macros often allow positional or keyword parameters that dictate what the conditional assembler program gen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Metadata
Metadata (or metainformation) is "data that provides information about other data", but not the content of the data itself, such as the text of a message or the image itself. There are many distinct types of metadata, including: * Descriptive metadata – the descriptive information about a resource. It is used for discovery and identification. It includes elements such as title, abstract, author, and keywords. * Structural metadata – metadata about containers of data and indicates how compound objects are put together, for example, how pages are ordered to form chapters. It describes the types, versions, relationships, and other characteristics of digital materials. * Administrative metadata – the information to help manage a resource, like resource type, and permissions, and when and how it was created. * Reference metadata – the information about the contents and quality of Statistical data type, statistical data. * Statistical metadata – also called process data, may ...

Nondeterministic Programming
A nondeterministic programming language is a programming language, language which can specify, at certain points in the Computer program, program (called "choice points"), various alternatives for Control flow, program flow. Unlike an Conditional (computer programming), if-then statement, the method of choice between these alternatives is not directly specified by the programmer; the program must decide at runtime (program lifecycle phase), run time between the alternatives, via some general method applied to all choice points. A programmer specifies a limited number of alternatives, but the program must later choose between them. ("Choose" is, in fact, a typical name for the nondeterministic operator.) A hierarchy of choice points may be formed, with higher-level choices leading to branches that contain lower-level choices within them. One method of choice is embodied in backtracking systems (such as Amb (evaluator), Amb, or unification in Prolog), in which some alternatives may " ...

Coupling (computer Programming)
A coupling is a device used to connect two shafts together at their ends for the purpose of transmitting power. The primary purpose of couplings is to join two pieces of rotating equipment while permitting some degree of misalignment or end movement or both. In a more general context, a coupling can also be a mechanical device that serves to connect the ends of adjacent parts or objects. Couplings do not normally allow disconnection of shafts during operation, however there are torque-limiting couplings which can slip or disconnect when some torque limit is exceeded. Selection, installation and maintenance of couplings can lead to reduced maintenance time and maintenance cost. Uses Shaft couplings are used in machinery for several purposes. A primary function is to transfer power from one end to another end (ex: motor transfer power to pump through coupling). Other common uses: * To alter the vibration characteristics of rotating units * To connect the driving and the driven ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Test Double
A test double is software used in software test automation that satisfies a dependency so that the test need not depend on production code. A test double provides functionality via an interface that the software under test cannot distinguish from production code. A programmer generally uses a test double to isolate the behavior of the consuming code from the rest of the codebase. A test double is usually a simplified version of the production code and may include capabilities specific to testing. Test doubles are used to build test harnesses. Uses A test double may be used to simplify tests, increase speed of execution or allow for deterministic results of an action. For example, a program that uses a database server is relatively slow and consumes significant system resources, which impedes testing productivity. A test might require data from the database that under normal system activity is regularly changing, so provides non-deterministic outputs for any given query. A ...
