Add a persisted test suite
`bundle exec rake test` (minitest, a default gem but pinned in
Gemfile for reproducibility) now covers what ad-hoc scripts kept
re-verifying by hand during development: Gpx/Fit/TrackStats parsing,
GpxStore/LiveTrackStore file/TTL logic, LiveTrackClient's payload
parsing, and app.rb's routes end to end via Rack::MockRequest.

MAPTOOL_DATA_DIR (new, app.rb) lets the suite point GPX_STORE/
LIVETRACK_STORE at a throwaway directory instead of real data/ —
without it every run would leave uploaded test files behind. Each
lib file's old `if __FILE__ == $0` self-check is now redundant with
real tests covering the same ground, so removed rather than kept as
a second copy of the same assertions. Wired into ci.yml so it isn't
just a local convenience.

== Web app only
[source,shell]
----
bundle install
bundle exec puma -C config/puma.rb
----
Open http://127.0.0.1:4567. For auto-reload during development, run
via the `rerun` gem instead:
[source,shell]
----
bundle exec rerun -- bundle exec puma -C config/puma.rb
----
TIP: Browsers apply heuristic caching to static files even without
explicit cache headers, so an edit to `public/` (or `views/`) can
appear not to have taken effect on the next reload. Force a real
reload (e.g. Ctrl/Cmd+Shift+R) if that happens.
== Offline map data
To enable the offline style, place a PMTiles file at
`data/offline.pmtiles` (see `docs/architecture.adoc` for how it is
served and styled). It is not part of the repository — obtain or
build one locally:
* The simplest source is a pre-built extract from
https://app.protomaps.com[protomaps.com's extract builder] — pick a
region and download it as `.pmtiles`. Its schema is what
`protomaps-themes-base` (the styling library used for the offline
style) expects.
* To convert some other vector tile source (e.g. an `.mbtiles` file)
into PMTiles, use the
https://github.com/protomaps/go-pmtiles[go-pmtiles] CLI:
`pmtiles convert in.mbtiles data/offline.pmtiles`.
Once the file is in place, `GET /api/offline-tiles` reports
`available: true` and the map defaults to the offline style.
== GNSS position (gpsd)
The "GNSS" control needs https://gpsd.io[gpsd] running and pointed at
a receiver (`gpsd /dev/ttyUSB0`, or whatever device the receiver shows
up as). On openSUSE, `gpsd` is a package with systemd units
(`gpsd.service` / `gpsd.socket`); on other distributions, check your
package manager. No app-side configuration is needed — it just
connects to `127.0.0.1:2947`, gpsd's default port.
To test without hardware, feed gpsd a fake NMEA stream over TCP
instead of a real serial device — gpsd accepts a `tcp://host:port`
source:
[source,shell]
----
# terminal 1: a TCP server repeating one NMEA GGA/RMC sentence pair
python3 - <<'PY' 5001
import socket, sys, time
def checksum(s):
cs = 0
for ch in s:
cs ^= ord(ch)
return f"{cs:02X}"
def sentence(body):
return f"${body}*{checksum(body)}\r\n"
port = int(sys.argv[1])
srv = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
srv.setsockopt(socket.SOL_SOCKET, socket.SO_REUSEADDR, 1)
srv.bind(("127.0.0.1", port))
srv.listen(1)
conn, _ = srv.accept()
gga = "GPGGA,123519,4808.916,N,01706.462,E,1,08,0.9,140.4,M,46.9,M,,"
rmc = "GPRMC,123519,A,4808.916,N,01706.462,E,000.5,084.4,230824,003.1,W"
while True:
conn.sendall((sentence(gga) + sentence(rmc)).encode())
time.sleep(1)

`GET /api/gnss/position` should then report the fake fix (Bratislava
Castle, in the sentences above) within a couple of seconds.
== Tests
`bundle exec rake test` runs the whole suite (`test/test_*.rb`,
Minitest — a default gem, but pinned in the `Gemfile`'s `:test` group
for reproducibility, same reasoning as `rake` itself). `test_app.rb`
drives `app.rb`'s routes end to end through `Rack::MockRequest` rather
than a real server; everything else tests one `lib/maptool/` module in
isolation. `MAPTOOL_DATA_DIR` (see `app.rb`) is pointed at a throwaway
`Dir.mktmpdir` by `test/test_helper.rb` before `app.rb` loads, so
running the suite never touches real `data/` — the app-level tests
also wipe that directory between each test (see `AppTestHelper#teardown`),
since `GPX_STORE`/`LIVETRACK_STORE` are process-wide constants shared
by every test in the run.
`LiveTrackClient`'s own tests use a synthetic fixture (no network) —
its parsing was checked against real Garmin sessions by hand during
development, not by the suite, since that needs a live, unexpired
session token to fetch. `Fit`'s tests likewise build a minimal FIT
file by hand rather than shipping a real device fixture; correctness
against real files (position/altitude fields, definition-message
framing, compressed-timestamp headers) was checked by hand against
`python-fitparse`'s test fixtures during development — see
`docs/architecture.adoc`.
== Continuous integration
`.gitea/workflows/ci.yml` runs on every push/PR against a self-hosted
Gitea Actions runner: `ruby -c` on every `.rb` file, a `require_relative
"app"` smoke check that the app loads without error, `bundle exec rake
test` (see above), and `node --check` on every file under
`public/js/` — no JS test suite, just a syntax check.
`.gitea/workflows/renovate.yml` runs
https://docs.renovatebot.com[Renovate] (the `renovate/renovate` image)
weekly (Mondays, also triggerable manually), opening PRs for outdated
dependencies (Bundler `Gemfile`/`Gemfile.lock`, auto-detected — no
`renovate.json` needed) against this Gitea instance
(`RENOVATE_PLATFORM=gitea`). It runs on the native `deploy` runner (see
`docs/deployment.adoc`) as a one-shot `docker run`, not a persistent
service. Needs a `RENOVATE_TOKEN` repo secret — a Gitea personal
access token (*Settings → Applications → Generate New Token*, with
repository read/write scope) from whichever account should author the
PRs; `RENOVATE_ONBOARDING=false` skips Renovate's usual first-PR
"configure me" step and goes straight to dependency update PRs using
its defaults.
