Loops Index

1 loops have been discarded from the report because their coverage is lower than the threshold set by object_coverage_threshold (0.01%). It represents about 0.00% of the application. To include them, change the value of object_coverage_threshold in the experiment directory configuration file, then rerun the command with the additionnal parameter --force-static-analysis
