Currently, in each loop during DisplayBuffer::update_() the display is
cleared by calling DisplayBuffer::clear().
This prevents more efficient display usages that do not render the
screen in each loop, but only if necessary. This can be helpful, for
example, if images are rendered. This would cause the loop time to be
exceeded frequently.
This change adds a new optional flag "auto_clear" that can be used to
control the clearing behavior. If unset, the DisplayBuffer defaults to
enabled auto clearing, the current behavior and thus backward compatible.
This flag applies to displays that use DisplayBuffer.
Example excerpt:
globals:
- id: state
type: bool
restore_value: no
initial_value: "false"
- id: state_processed
type: bool
restore_value: no
initial_value: "false"
switch:
- platform: template
name: "State"
id: state_switch
lambda: |-
return id(state);
turn_on_action:
- globals.set:
id: state
value: "true"
- globals.set:
id: state_processed
value: "false"
turn_off_action:
- globals.set:
id: state
value: "false"
- globals.set:
id: state_processed
value: "false"
display:
- platform: ili9341
# ...
auto_clear_enabled: false
lambda: |-
if (!id(state_processed)) {
it.fill(COLOR_WHITE);
if (id(state)) {
it.image(80, 20, id(image1));
} else {
it.image(80, 20, id(image2));
}
id(state_processed) = true;
}

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 |
