pEchoVar
Utility app correctness tests for pEchoVar. These cases verify live echo mapping, boolean inversion, fan-out, duplicate mapping de-duplication, latest-value handling, EFlipper component maps, filters, custom separators, cycle suppression, invalid flipper suppression, and independent named flippers.
Stem Mission
The stem mission runs one MOOS community with pEchoVar, uTimerScript, pMissionEval, pMissionHash, and pLogger. The harness writes case-specific echo/flip mappings and scripted source mail, then grades direct echo variables plus alog evidence for structured EFlipper payloads and suppression.
Examples
Case Matrix
numeric_echo_pass
Maps ECHO_SRC_NUM -> ECHO_OUT_NUM and posts numeric 42.5, testing preservation of numeric mail; passes when pMissionEval observes ECHO_OUT_NUM=42.5.
string_echo_pass
Maps ECHO_SRC_STR -> ECHO_OUT_STR and posts string ready, testing preservation of string mail without numeric coercion; passes when pMissionEval observes ECHO_OUT_STR=ready.
bool_switch_true_pass
Maps ECHO_SRC_BOOL !-> ECHO_OUT_BOOL and posts lowercase true, testing boolean inversion with case preservation; passes when pMissionEval observes lowercase false.
bool_switch_mixed_case_pass
Posts True through a !-> mapping, testing the title-case boolean branch; passes when pMissionEval observes ECHO_OUT_BOOL=False.
bool_switch_upper_false_pass
Posts uppercase FALSE through a !-> mapping, testing the uppercase boolean branch; passes when pMissionEval observes ECHO_OUT_BOOL=TRUE.
bool_switch_numeric_passthrough_pass
Posts numeric 7 through a !-> mapping, testing that boolean inversion applies only to string mail; passes when pMissionEval observes unchanged numeric ECHO_OUT_NUM=7.
bool_switch_nonbool_passthrough_pass
Posts the non-boolean string maybe through a !-> mapping, testing string passthrough outside recognized boolean spellings; passes when pMissionEval observes ECHO_OUT_BOOL=maybe.
multi_target_echo_pass
Maps one ECHO_SRC_MULTI=alpha publication to both ECHO_OUT_A and ECHO_OUT_B, testing one-to-many fan-out; passes when pMissionEval observes alpha on both targets.
acyclic_chain_echo_pass
Configures ECHO_SRC_STR -> ECHO_OUT_A -> ECHO_OUT_B and posts chain, testing propagation through a two-edge acyclic graph; passes when both downstream variables equal chain.
duplicate_mapping_single_post_pass
Declares ECHO_SRC_STR -> ECHO_OUT_STR twice and posts dedupe, testing duplicate-pair removal during configuration; passes when the value is correct and the pre-evaluation logs contain exactly one ECHO_OUT_STR publication.
default_repeated_source_posts_each_pass
Leaves echo_latest_only false and posts first then second in one MOOS mail batch, testing release of every queued update; passes when the final value is second and the logs contain exactly two ECHO_OUT_LATEST publications.
latest_only_repeated_source_pass
Sets echo_latest_only=true and posts first then second in the same MOOS mail batch, testing replacement of the older held message before release; passes when final ECHO_OUT_LATEST=second is published exactly once.
flip_component_pass
Maps x and y from x=10,y=20,type=redeploy to xcenter and ycenter with # as the destination separator; passes when the pre-evaluation logs contain exact payload xcenter=10#ycenter=20.
flip_explicit_param_syntax_pass
Configures filter = type == redeploy and component = x -> xcenter instead of shorthand entries, testing explicit EFlipper parameter syntax; passes when input type=redeploy,x=18 produces xcenter=18.
flip_explicit_filter_suppresses_pass
Uses the same explicit filter = and component = syntax but posts type=loiter,x=18, proving the explicit filter controls output rather than merely parsing; passes when no FLIP_OUT publication occurs.
flip_filter_match_pass
Filters on type == redeploy, maps x and y, and posts a matching payload; passes when the logs contain exact xcenter=11#ycenter=21 output.
flip_multiple_filters_match_pass
Requires both type == redeploy and mode == survey before mapping x and y; passes when the matching input produces exact xcenter=19,ycenter=29.
flip_filter_case_insensitive_match_pass
Configures lowercase type == redeploy but posts uppercase TYPE=REDEPLOY, testing case-insensitive filter keys and values; passes when the mapped output is exactly xcenter=14,ycenter=24.
flip_missing_filter_allows_pass
Configures type == redeploy but posts only x=12,y=22, testing the rule that an absent filtered field does not reject the message; passes when exact xcenter=12,ycenter=22 is published.
flip_filter_suppresses_pass
Configures type == redeploy and posts mismatched type=loiter, testing single-filter rejection; passes when no FLIP_OUT publication occurs before evaluation.
flip_multiple_filters_suppress_pass
Posts matching type=redeploy but mismatched mode=loiter against two filters, testing that any present mismatch rejects the message; passes when no FLIP_OUT publication occurs.
flip_custom_separator_pass
Parses mode=survey|x=5|y=-2 with source separator | and serializes mapped fields with destination separator @; passes when the logs contain exact xpos=5@ypos=-2.
flip_component_case_sensitive_pass
Maps uppercase component X from input containing both x=15 and X=16, testing case-sensitive component lookup; passes when xcenter=16 appears and xcenter=15 does not.
flip_unmapped_component_omitted_pass
Maps only x from x=8,z=99, testing omission of an unmapped source component; passes when the complete FLIP_OUT value is exactly xcenter=8.
flip_no_mapped_fields_no_output_pass
Configures a valid x -> xcenter component but posts only y=33, testing empty flip results when no source field is mapped; passes when no FLIP_OUT publication occurs.
flip_duplicate_component_repeats_pass
Posts x=10,x=11,y=20 through x -> xcenter and y -> ycenter, testing preservation and order of duplicate source components; passes when the exact payload is xcenter=10,xcenter=11,ycenter=20.
flip_empty_value_pass
Maps source component x from the payload x=, testing preservation of an empty component value; passes when the complete FLIP_OUT value is exactly xcenter=.
cycle_guard_no_echo_pass
Configures the two-node cycle CYCLE_A -> CYCLE_B -> CYCLE_A and posts CYCLE_A=one, testing startup cycle rejection; passes when no CYCLE_B publication occurs.
self_cycle_guard_no_echo_pass
Configures CYCLE_A -> CYCLE_A and posts CYCLE_A=self, testing direct self-cycle rejection; passes when the logs contain exactly one CYCLE_A publication, the original source post only.
indirect_cycle_blocks_all_pass
Adds a three-node cycle plus an unrelated valid ECHO_SRC_STR -> ECHO_OUT_STR mapping, testing the app-wide guard after any cycle is detected; passes when neither cyclic CYCLE_B nor unrelated ECHO_OUT_STR is published.
invalid_flip_no_output_pass
Configures source and destination variables but no component mapping, testing rejection of an incomplete EFlipper; passes when source mail arrives without any FLIP_OUT publication.
invalid_flip_alias_no_output_pass
Configures FLIP_SRC as both source and destination with an x -> xcenter mapping, testing source/destination alias rejection; passes when the logs contain exactly the one original FLIP_SRC=x=17 post and no FLIP_OUT publication.
shared_source_dual_flip_pass
Gives two named EFlippers the same FLIP_SRC=x=31,y=41, mapping x to FLIP_OUT and y to ECHO_OUT_STR; passes when the exact bound publications are FLIP_OUT=xcenter=31 and ECHO_OUT_STR=ypos=41.
dual_flip_independent_pass
Gives two named EFlippers separate sources and destinations, posting x=44 to one and word=bravo to the other; passes when the exact bound publications are FLIP_OUT=xcenter=44 and ECHO_OUT_STR=word_out=bravo.
