J. Nick Koston 99c80b7dfa [ci] Address copilot review feedback on import-time check
- determine-jobs: trigger on changes to requirements_test.txt too; that
  file is hashed into the venv cache key and installed during
  restore-python, so a change there can alter the import environment.
- ci.yml: merge the --check and --har steps so we only run
  importtime-waterfall once per job (was measuring twice: ~7-8s of
  wasted CI time per run). Uses the new script/check_import_time.py
  --check --har <path> combination; the HAR reflects the same
  measurement that produced the pass/fail decision.
- script/check_import_time.py: refactor the CLI so --har is a standalone
  option rather than a mutually-exclusive mode. --check and --update
  each accept an optional --har PATH that writes the HAR from the same
  subprocess invocation. Plain --har is still supported for local use.
- tests: add tests/script/test_check_import_time.py covering HAR parsing,
  root lookup, offender ranking/dedup, budget round-trip, and the three
  --check exit paths (pass, regression, missing budget) plus the new
  --check --har combined write. Add requirements_test.txt case to the
  should_run_import_time parametrized test.

Tests for ESPHome

This directory contains some tests for ESPHome. At the moment, all the tests only work by simply executing esphome over some YAML files that are made to test whether the yaml gets converted to the proper C++ code.

Of course this is all just very high-level and things like unit tests would be much better. So if you have time and know how to set up a unit testing framework for python, please do give it a try.

When adding entries in test_.yaml files we usually need only one file updated, unless conflicting code is generated for different configurations, e.g. wifi and ethernet cannot be tested on the same device.

Current test_.yaml file contents.

Test name Platform Network BLE

test6.yaml RP2040 wifi N/A
test7.yaml ESP32-C3 wifi N/A
test8.yaml ESP32-S3 wifi None
test10.yaml ESP32 wifi None
