# Run native PlatformIO unit tests and emit a single, unambiguous RED/AMBER/GREEN verdict.
|
|
|
|
|
#
|
|
|
|
|
# Why this exists: PlatformIO reports failures three different ways ([FAILED], :FAIL:,
|
|
|
|
|
# [ERRORED]) and an all-pass run prints "N succeeded" with NO "0 failed" clause — so naive
|
|
|
|
|
# greps produce false greens (see .notes/test-passfail-filter.md). This script encodes the
|
|
|
|
|
# correct logic once, and cross-checks the number of suites that actually ran against the
|
|
|
|
|
# canonical set in test/ so a suite silently going missing shows up as AMBER, not green.
|
|
|
|
|
#
|
|
|
|
|
# Usage:
|
|
|
|
|
# ./bin/run-tests.sh # run all suites, full RAG + count cross-check
|
|
|
|
|
# ./bin/run-tests.sh -f test_utf8 # run one suite (no count cross-check)
|
|
|
|
|
# ./bin/run-tests.sh -e native # override env (default: coverage)
|
|
|
|
|
# ./bin/run-tests.sh --quiet # only print the final RESULT line
|
|
|
|
|
#
|
|
|
|
|
# Exit codes: 0 = GREEN, 1 = RED, 2 = AMBER.
|
|
|
|
|
#
|
|
|
|
|
# The final line is machine-readable, e.g.:
|
|
|
|
|
# RESULT: GREEN 19/19 suites passed
|
|
|
|
|
# RESULT: AMBER 17/19 suites ran (missing: test_radio test_serial) — all that ran passed
|
|
|
|
|
# RESULT: RED test_traffic_management: 1 failed (or: build/crash error)
|
|
|
|
|
# RESULT: RED sanitizer fault — SUMMARY: AddressSanitizer: 1272 byte(s) leaked (tests may have
|
|
|
|
|
# all passed; the coverage build aborts at exit on an ASan/LSan fault — often shown only
|
|
|
|
|
# as [ERRORED]/SIGHUP. The script names it and points at running the binary bare.)
