Utility Infrastructure
Utility infrastructure tests for uLoadWatch. These cases verify threshold counters, near and hard threshold boundary behavior, low-threshold ignore behavior, clamped near-threshold behavior, breach-trigger holdoff, app-specific threshold matching, and threshold-name case sensitivity.
Stem Mission
The stem mission runs a single shoreside MOOS community with uLoadWatch, uTimerScript, pAutoPoke, and pMissionEval. Case overlays change only load-watch configuration, scripted DB_UPTIME mail, and mission-owned threshold pass/fail conditions.
Examples
These uLoadWatch GIFs are generated explanatory views instead of raw pMarineViewer captures because the meaningful evidence is threshold mail and breach counters. The visuals call out the evidence that makes each case pass.
Case Matrix
loadwatch_no_breach_pass
Sets the generic gap threshold to 100 seconds and posts UTILITY_ITER_GAP=1.5; passes when both hard- and near-breach counts remain zero.
loadwatch_near_breach_pass
Sets gapthresh=3.0 and near_breach_thresh=0.5, making the derived near boundary 2.0, then posts a 2.6-second gap; passes when a near breach and positive near count appear while hard-breach count remains zero.
loadwatch_near_boundary_no_breach_pass
Posts a 2.0-second gap exactly at the derived near boundary for threshold 3.0 and factor 0.5; passes when both near- and hard-breach counts remain zero, demonstrating the comparison is strict.
loadwatch_breach_pass
Posts a 3.5-second gap above the 3.0-second generic threshold with breach_trigger=0; passes when ULW_BREACH=true and both hard- and near-breach counts are positive.
loadwatch_trigger_suppresses_first_pass
Sets breach_trigger=1 and posts one 3.5-second threshold crossing; passes when near-breach count is positive but hard-breach count remains zero.
loadwatch_trigger_second_breaches_pass
Sets breach_trigger=1 and posts 3.5- and 3.7-second crossings; passes when ULW_BREACH=true, hard-breach count is positive, and near-breach count is at least two.
loadwatch_lowercase_any_no_breach_pass
Configures case-sensitive app=any while posting UTILITY_ITER_GAP=3.5; passes when neither breach counter increments, demonstrating lowercase any does not provide the ANY fallback.
loadwatch_specific_app_breach_pass
Sets a 3.0-second threshold for UTIMERSCRIPT and posts UTILITY_ITER_GAP=3.5; passes when ULW_BREACH=true and both breach counts are positive.
loadwatch_specific_app_ignores_other_pass
Configures a threshold only for PHOSTINFO and posts OTHER_ITER_GAP=3.5; passes when both breach counts remain zero.
loadwatch_hard_boundary_no_breach_pass
Posts a 3.0-second gap exactly at the hard threshold; passes when hard-breach count remains zero while near-breach count is positive, demonstrating the hard comparison is strict.
loadwatch_low_threshold_ignored_pass
Configures gapthresh=1.0 and posts a 3.5-second gap; passes when both breach counts remain zero, exercising the code path that ignores thresholds at or below 1.0.
loadwatch_near_thresh_clamped_high_pass
Configures near_breach_thresh=2.0, which is clamped to 1.0, and posts a 2.5-second gap below the resulting 3.0-second near boundary; passes when both breach counts remain zero.
