Comparing TrueLogs that are generated during Try Script runs alongside the corresponding TrueLogs that were generated during application recording is an effective means of pinpointing problems in load testing scripts.
Difference tables, available from the Differences page, automatically list the differences that are detected between replay TrueLogs and corresponding record TrueLogs.
Difference mode, which is enabled by default, is a special kind of compare mode in which text differences in the In Body, Out Body, In Header, and Out Header pages are marked in color (red and green with a gray background).
