test(txt) initial unit tests and general code cleanup/fixes (#2623) 
* test(txt): Add test for identifying empty text when trying to get next line

* test(txt): Rename next line empty string handling test

* test(txt): Add tests for _lv_txt_is_cmd

* test(txt): Add initial tests for _lv_txt_ins

* fix(txt): Check for NULL before using strlen

Passing NULL to strlen is not defined, so we should avoid it

* txt: Update docs

Remove docs from source file and add comment about pointers to NULL terminated arrays where necessary

* txt: Misc update in encoded_size

* test(txt): first tests for _lv_txt_cut

* tests: Remove -Wmissing-prototype flag from compilation

This will allow us to have cleaner test cases files.

* test(txt): Remove test (funtion) prototypes as they're no longer necessary

* Update src/misc/lv_txt.h

* Update src/misc/lv_txt.h

* Revert "tests: Remove -Wmissing-prototype flag from compilation"

This reverts commit 8b3217de8d9210eb2e6da5e94c0735beb2735be7.

* test(txt): Use pragma to disable missing-prototype warning

* test: use extended set of compile options for test cases

* Revert "test(txt): Use pragma to disable missing-prototype warning"

This reverts commit 64909e30ed124ca1e8ca390ca0639479c3e34f44.

* test(txt): Add assert to test_txt_cut_len_longer_than_string test

* test(txt): Add test for _lv_txt_encoded_next on valid ascii input

* test(txt): Add tests for _lv_txt_encoded_next with 2 byte long inputs

* test(txt): Add tests for _lv_txt_encoded_next with 3 byte long inputs

* test(txt): Add tests for _lv_txt_encoded_next with 4 byte long inputs

* cleanup(txt): Add helper macros to identify ASCII and UTF8 codes

* cleanup(txt): Add missing LV_ prefix to helper macros

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

  1. Run all executable tests with ./tests/main.py test.
  2. Build all build-only tests with ./tests/main.py build.
  3. 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)
