J. Nick Koston 899e88be72 [core] Let the yaml editor insert lines, write with a rollback and restore
apply_line_edits rewrites the located lines in place, reloads every touched
file and drops the validated caches, undoing everything on any failure;
restore_files puts the originals back only over what was written. A key in
a mapping merge_config rebuilt is placed by its value's line.

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.
