hibafedezés

Hibafedezés, in Hungarian, translates to defect coverage or fault coverage. It is a crucial concept in software testing and engineering, referring to the extent to which a set of tests can detect potential defects or faults within a system. High hibafedezés means that the tests are comprehensive and likely to uncover most, if not all, existing bugs. Conversely, low hibafedezés suggests that many defects might remain undetected, posing a risk to the system's quality and reliability.

Achieving effective hibafedezés involves careful test planning and execution. Various metrics and techniques are employed to measure and improve it, such as statement coverage, branch coverage, path coverage, and condition coverage. Each metric focuses on different aspects of the code or system behavior. For instance, statement coverage ensures that every line of code has been executed at least once by the test suite. Branch coverage goes further by verifying that each possible outcome of a conditional statement (like an if-else block) has been tested.

The goal of hibafedezés is not necessarily to achieve 100% coverage, which can be prohibitively expensive and time-consuming, but rather to reach a level of coverage that provides confidence in the system's quality given the project's constraints and risk tolerance. It is an iterative process, where test coverage is analyzed, gaps are identified, and new tests are developed to address those gaps, thereby increasing the overall hibafedezés and reducing the likelihood of critical failures in production.
