The batch UART read change in #13818 exposed a latent bug where the UART parser could start accumulating bytes mid-frame after module restart, causing an infinite cycle of "Max command length exceeded" warnings that prevented initialization. Add header validation for the first 4 bytes of each frame, ensuring the parser only accumulates data starting from a valid DATA_FRAME_HEADER (AA FF 03 00) or CMD_FRAME_HEADER (FD FC FB FA). Non-matching bytes are discarded until a valid frame start is found. Fixes #14131 Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
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.
