In programming jargon, a plate of spaghetti means a poor quality software coupling too strong and the source code being difficult to read. For the most critical modules, their seamless availability may be based on a strategy of redundancy physical instantiation.
The abstraction is aimed at reducing the overall complexity of software by reducing the number of modules. It can also bring uniformity of software that increases usability by making it easier to learn and use.
Concealment is to completely separate the technical details of the software functionality on the principle of the black box, to improve maintainability, portability and interoperability. Testing activities are often equated with its enforcement activity. However, even if this phase is the most important because it allows the detection of defects, other activities can be practiced to improve the relevance of the activity execution.
Planning or organization defines the strategy that will be implemented throughout the testing phase by an IT management company NZ. Conception. This activity consists in writing tests that will be represented. It defines for each test run what will be: pre-requisite to have to perform the test, the actions that will be undertaken and the results that are expected.
Execution. This activity is strictly speaking a software test. If unusual behavior is detected during this phase, it is reported in detail. This activity will synthesize the test phase when it is complete. It describes all the events that occurred during the test and can sometimes make recommendations about the quality of the tested software.
Unlike the previously described activities that follow a chronological order, this activity is carried out concurrently with the design and execution. It allows to provide information about the progress of each activity. For this, the indicators are used .
The most common are: the number of test cases designed on the number of tests provided, the number of tests performed on the number of tests planned or constructed, the number of tests failed or successful on the total number of tests planned.
Structuring instructions and data makes it clearly visible in the source code, it outlines the organization of instructions and manipulated information, which improves maintainability and facilitates the detection of bugs.
Many programming languages support or require writing source code according to the principles of structure, modularity and concealment. This is the case of structured programming languages and object oriented programming. Unlike the literature on code, user documents are usually quite distant from the source code of the program and simply describe how it is used.
