The process of screeningin typically involves several steps. First, the complete set of test cases is analyzed to understand their coverage and importance. This analysis may involve examining the code, requirements, and historical data to determine which test cases are most likely to reveal critical bugs. Second, a subset of test cases is selected based on predefined criteria, such as coverage of critical functionality, risk assessment, or historical failure rates. Third, the selected test cases are executed, and the results are analyzed to identify any defects or issues.
Screeningin can be performed using various techniques, including manual selection, automated tools, or a combination of both. Manual selection involves human judgment to choose the most relevant test cases, while automated tools use algorithms and heuristics to identify and prioritize test cases. The choice of technique depends on factors such as the size and complexity of the software, the available resources, and the specific goals of the testing effort.
The benefits of screeningin include reduced testing time and resource consumption, as well as improved defect detection rates. By focusing on the most critical test cases, screeningin can help identify and address the most significant issues early in the development process, leading to higher-quality software and reduced overall costs. However, it is important to note that screeningin may also introduce some risks, such as missing defects that are not covered by the selected test cases or introducing bias in the testing process.
In summary, screeningin is a valuable technique in software testing that helps manage the complexity and scale of testing efforts. By selecting and prioritizing the most critical test cases, screeningin can improve defect detection rates, reduce testing time and resources, and ultimately lead to higher-quality software.
