Tests for LVGL

The tests in the folder can be run locally and automatically by GitHub CI.

Running locally

Requirements (Linux)

Install requirements by:

scripts/install-prerequisites.sh

Run test

Run all executable tests with ./tests/main.py test.
Build all build-only tests with ./tests/main.py build.
Clean prior test build, build all build-only tests, run executable tests, and generate code coverage report ./tests/main.py --clean --report build test.

For full information on running tests run: ./tests/main.py --help.

Running automatically

GitHub's CI automatically runs these tests on pushes and pull requests to master and releasev8.* branches.

Directory structure

src Source files of the tests
- test_cases The written tests,
- test_runners Generated automatically from the files in test_cases.
- other miscellaneous files and folders
ref_imgs - Reference images for screenshot compare
report - Coverage report. Generated if the report flag was passed to ./main.py
unity Source files of the test engine

Add new tests

Create new test file

New test needs to be added into the src/test_cases folder. The name of the files should look like test_<name>.c. The basic skeleton of a test file copy _test_template.c.

Asserts

See the list of asserts here.

There are some custom, LVGL specific asserts:

TEST_ASSERT_EQUAL_SCREENSHOT("image1.png") Render the active screen and compare its content with an image in the ref_imgs folder. If the compare fails lvgl/test_screenshot_error.h is created with the content of the frame buffer as an image. To see the that image #include "test_screenshot_error.h" and call test_screenshot_error_show();.
TEST_ASSERT_EQUAL_COLOR(color1, color2) Compare two colors.

Adding new reference images

The reference images can be taken by copy-pasting the test code in to LVGL simulator and saving the screen. LVGL needs to

800x480 resolution
32 bit color depth
LV_USE_PERF_MONITOR and LV_USE_MEM_MONITOR disabled
use the default theme, with the default color (don't set a theme manually)
