J. Nick Koston 7c2254d8ee Refuse knob-plus-raw define splits, lex build flags once, harden the ld cache
A raw MMU_* define alongside a PIO_FRAMEWORK_ARDUINO_MMU_* knob, or a
raw TCP_MSS/LWIP_* alongside the lwIP knobs, would win the compile line
while the linker script or prebuilt library keeps the knob's values;
both now raise like the no-knob case. _MMU_VARIANTS holds tuples and the
resolved config gets a copy, so nothing aliases the module table.
_lexed_build_flags lexes once and both consumers accept the tokens, so
a malformed entry warns once per build. The linker-script stamp covers
the header's size and mtime, an unreadable or non-UTF-8 cache
regenerates instead of aborting, plain-form linker flags warn that they
are not routed to the link line, and a moved rate-table anchor surfaces
as a named build error.

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
test1.yaml ESP32 wifi None
test2.yaml ESP32 ethernet esp32_ble_tracker
test3.yaml ESP8266 wifi N/A
test4.yaml ESP32 ethernet None
test5.yaml ESP32 wifi ble_server
test6.yaml RP2040 wifi N/A
test7.yaml ESP32-C3 wifi N/A
test8.yaml ESP32-S3 wifi None
test10.yaml ESP32 wifi None
