History

test(switch): add initial unit test (#2794 )

* test(switch): Add test file and state at creation test

* test(switch): Event handler called only once per click

* test(switch): Add test state change when event bubbling is enabled

* test(switch): Cleanup event bubbling test

* tests(switch): Update memory test and add basic animation test

* test(switch) Add helper to click on switch

* test(switch) Add basic test for knob size calculation

* misc(switch) Replace switch knob rounding error magic number with define

* test(switch) Improve animation test

Properly wait for 50ms after clicking on the switch using lv_test_indev_wait and also assert on switch state after the first and second clicks

* test(switch) cleanup

* misc(switch) Cleanup

* switch: Expose _LV_SWITCH_KNOB_EXT_AREA_CORRECTION value

So we can use it when testing extra draw size

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 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)
