### Tests:
3+
4+
- `api/`: These tests are to test MicroPython-LVGL bindings. They can be
5+
automated/included in CI.
6+
To run from `micropython/tests`:
7+
```
8+
./run-tests.py ../../user_modules/lv_binding_micropython/tests/api/basic*.py -r .
9+
```
10+
11+
- `display/`: These are to test the `api` + display driver. Intended for HIL
12+
(Hardware in the loop) testing. Display only, no touch interface, touch is
13+
automated and simulated in software.
14+
To run from `micropython/tests`:
15+
```
16+
./run-tests.py ../../user_modules/lv_binding_micropython/tests/display/basic*.py -r .
17+
```
18+
e.g. in unix port a display will appear to provide visual feedback.
19+
20+
21+
- `indev/`: These are to test the `display` + indev (touch) driver. Intended for
22+
interactive HIL testing, e.g. they expect user input to complete the test.
23+
24+
To run from `micropython/tests`:
25+
```
26+
./run-tests.py ../../user_modules/lv_binding_micropython/tests/indev/basic*.py -r .
27+
```
28+
e.g. in unix port a display will appear to allow user input.
29+
30+
All tests are intended/expected to be run both in desktop (unix port) and in devices with the same result.
31+
32+
For devices `testrunner.py`, `testdisplay.py` and `display_mode.py` need to be
33+
uploaded. Also for display/indev testing a `hwdisplay.py` with a display driver
34+
called `display` is expected. This `display` driver is expected to have at least a
35+
```py
36+
37+
def blit(self, x1, y1, w, h, buff):
38+
```
39+
method or handle the lv display setup by itself (e.g setting buffers, `flush_cb`, etc)
40+
41+
For interactive indev tests, it is required to have a
42+
```py
43+
44+
def read_cb(self, indev, data):
45+
```
46+
method too, or handle indev creation by itself.
