Test Stub
A test stub is a test double that provides static values to the software under test. A test stub provides canned answers to calls made during the test, usually not responding at all to anything outside what's programmed in for the test.Fowler, Martin (2007), ''Mocks Aren't Stubs'(Online)/ref> A stub may be coded by hand, generated via a tool or be created as a dedicated part of a larger system such as a stub server or service.

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 ...

Canned Response
Canned responses are predetermined responses to common questions. In fields such as technical support, canned responses to frequently asked questions may be an effective solution for both the customer and the technical adviser, as they offer the possibility to provide a quick answer to common inquiries while requiring little human intervention. Improperly used, canned responses can prove frustrating to users by providing inadequate answers. Technical support Assisting human operators In text-based technical support systems, the operator may insert a canned response triggered by keystrokes or from a drop-down menu, rather than typing the same answer repeatedly or pasting from some other resource. For example, if a support representative at an ISP's technical support team is asked to explain how to add an attachment to an email, rather than typing in all the details, the support representative may choose the response from a drop down menu, and it gets inserted into the respons ...

Source Code
In computing, source code, or simply code or source, is a plain text computer program written in a programming language. A programmer writes the human readable source code to control the behavior of a computer. Since a computer, at base, only understands machine code, source code must be Translator (computing), translated before a computer can Execution (computing), execute it. The translation process can be implemented three ways. Source code can be converted into machine code by a compiler or an assembler (computing), assembler. The resulting executable is machine code ready for the computer. Alternatively, source code can be executed without conversion via an interpreter (computing), interpreter. An interpreter loads the source code into memory. It simultaneously translates and executes each statement (computer science), statement. A method that combines compilation and interpretation is to first produce bytecode. Bytecode is an intermediate representation of source code tha ...

Software Tool
A programming tool or software development tool is a computer program that is used to software development, develop another computer program, usually by helping the developer manage computer files. For example, a programmer may use a tool called a source code editor to edit source code files, and then a compiler to convert the source code into machine code files. They may also use Build automation, build tools that automatically package executable program and data files into shareable package manager, packages or Installation (computer programs), install kits. A set of tools that are run one after another, with each tool feeding its output to the next one, is called a toolchain. An integrated development environment (IDE) integrates the function of several tools into a single program. Usually, an IDE provides a source code editor as well as other built-in or Plug-in (computing), plug-in tools that help with compiler, compiling, debugging, and software test, testing.

Stub (distributed Computing)
In distributed computing, a stub is a program that acts as a temporary replacement for a remote service or object. It allows the client application to access a service as if it were local, while hiding the details of the underlying network communication. This can simplify the development process, as the client application does not need to be aware of the complexities of distributed computing. Instead, it can rely on the stub to handle the remote communication, while providing a familiar interface for the developer to work with. Application The stub represents a remote object or service on a local system. It acts as a proxy for the remote service and allows the client program to make method calls on the remote object as if it were local. The process of generating stubs involves creating a client-side proxy object that provides the same interface as the remote service, but routes method calls to the actual remote object. In distributed computing, a stub is a piece of code that con ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mock Object
In computer science, a mock object is an object that imitates a production object in limited ways. A programmer might use a mock object as a test double for software testing. A mock object can also be used in generic programming. Analogy A mock object can be useful to the software tester like a car designer uses a crash test dummy to simulate a human in a vehicle impact. Motivation In a unit test, mock objects can simulate the behavior of complex, real objects and are therefore useful when a real object is impractical or impossible to incorporate into a unit test. If an object has any of the following characteristics, it may be useful to use a mock object in its place: * it supplies non-deterministic results (e.g. the current time or the current temperature) * it has states that are difficult to create or reproduce (e.g. a network error) * it is slow (e.g. a complete database, which would have to be prepared before the test) * it does not yet exist or may change behavior ...

Method Stub
A method stub is a short and simple placeholder for a method that is not yet written for production needs. Generally, a method stub contains just enough code to allow it to be used a declaration with any parameters, and if applicable, a return value. A method stub may be used to implement an interface that is defined but for which the implementation is not available. Example In the following example pseudocode, the function returns a particular value even though ultimately it is supposed to read a value from a hardware source. It returns a valid value, allowing consuming code to be runnable. The function ignores the input parameter which is common for a stub. function ReadThermometer(Source source) return 28 end function Related Distributed computing In distributed computing, ''stub'' is like a mock object simulates existing code, such as a procedure on a remote machine. Such stubs can be useful in porting. In RMI nomenclature, a stub on the client-side co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Software Testing
Software testing is the act of checking whether software satisfies expectations. Software testing can provide objective, independent information about the Quality (business), quality of software and the risk of its failure to a User (computing), user or sponsor. Software testing can determine the Correctness (computer science), correctness of software for specific Scenario (computing), scenarios but cannot determine correctness for all scenarios. It cannot find all software bug, bugs. Based on the criteria for measuring correctness from an test oracle, oracle, software testing employs principles and mechanisms that might recognize a problem. Examples of oracles include specifications, Design by Contract, contracts, comparable products, past versions of the same product, inferences about intended or expected purpose, user or customer expectations, relevant standards, and applicable laws. Software testing is often dynamic in nature; running the software to verify actual output ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
