In Spectrum-Based Fault Localization (SBFL), a suspiciousness score is assigned to each code element based on test coverage and test outcomes. The scores are then used to rank the code elements relative to each other in order to aid the programmer during the debugging process when seeking the source of a fault. However, probably none of the known S...

In software debugging, fault localization is the most difficult, expensive, tedious, and time-consuming task, particularly for large-scale software systems.

Spectrum-Based Fault Localization (SBFL) uses a mathematical formula to determine a suspicion score for each program element (such as a statement, method, or class) based on fundamental statistics (e.g., how many times each element is executed and not executed in passed and failed tests) taken from test coverage and results. Based on the calculated...

In Spectrum-Based Fault Localization (SBFL), a suspicion score for each program element (e.g., statement, method, or class) is calculated by using a risk evaluation formula based on tests coverage and their results. The elements are then ranked from most suspicious to least suspicious based on their scores. The elements with the highest scores are...

Spectrum-Based Fault Localization (SBFL) computes suspicion scores, using risk evaluation formulas, for program elements (e.g., statements, methods, or classes) by counting how often each element is executed or not executed by passing versus failing test cases. The elements are then ranked from most suspicious to least suspicious based on their sco...

In Spectrum-Based Fault Localization (SBFL), when some failing test cases indicate a bug, a suspicion score for each program element (e.g., statement, method, or class) is calculated using a risk evaluation formula based on basic statistics (e.g., covering/not covering program element in passing/failing test) extracted from test coverage and test r...

The Internet of Things (IoT) is a new technological trend involved in many of our day-to-day activities, and its applications cover many aspects of our lives, including healthcare, military, industry, etc. Therefore, testing IoT applications, services, and systems is crucial to avoid losses in resources and lives, especially in critical application...
