Logical coupling (or evolutionary coupling or change coupling) analysis exploits the release history of a software system to find change patterns among modules or classes: e.g., entities that are likely to be changed together or sequences of changes (a change in a class A is always followed by a change in a class B).
Loose coupling in broader distributed system design is achieved by the use of transactions, queues provided by message-oriented middleware, and interoperability standards. [ 2 ] Four types of autonomy, which promote loose coupling, are: reference autonomy , time autonomy , format autonomy , and platform autonomy .
System testing often serves the purpose of evaluating the system's compliance with its specified requirements [citation needed] – often from a functional requirement specification (FRS), a system requirement specification (SRS), another type of specification or multiple. System testing can detect defects in the system as a whole. [citation ...
In normalized systems separation of concerns is one of the four guiding principles. Adhering to this principle is one of the tools that helps reduce the combinatorial effects that, over time, get introduced in software that is being maintained. In normalized systems separation of concerns is actively supported by the tools.
Setup: Put the Unit Under Test (UUT) or the overall test system in the state needed to run the test. Execution: Trigger/drive the UUT to perform the target behavior and capture all output, such as return values and output parameters. This step is usually very simple. Validation: Ensure the results of the test are correct.
The technology, they continued, could create "individually themed online slot games that can respond to a player's voice and even generate novel content in response to a player's behavior and game ...
Two men slashed each other as an early-morning clash turned vicious on the subway platform at Grand Central Tuesday, the latest in a rash of violence in and near the trains, police said.
Officials in Arizona this week said nearly a half-dozen animals including a cheetah and a mountain lion at a Phoenix-area zoo died and others are sick after being exposed to the bird flu.
