Then run bzt test.yml. After the tool finishes, observe resulting summary stats in console log (for more reporting options, see Generating Test Reports). All artifact files from the run will be placed in the directory mentioned in console log. Read more on command-line tool usage Command-Line Tool.

Available in the unstable snapshot (August 2025):

Taurus now fully excludes any labels specified in the ignored_labels option from the overall percentile calculation in the aggregator. If you use the ignored_labels feature, those labels will not affect the percentiles reported in the summary/overall statistics.

This change ensures that ignored labels are consistently excluded from both score and percentile calculations.
