/**
|
|
* \defgroup pwtest The pwtest PipeWire Test Suite
|
|
* \brief `pwtest` is a test runner framework for PipeWire.
|
|
*
|
|
* It's modelled after other
|
|
* test suites like [check](https://libcheck.github.io/check/)
|
|
* and draws a lot of inspiration from the [libinput test
|
|
* suite](https://wayland.freedesktop.org/libinput/doc/latest/).
|
|
*
|
|
* `pwtest` captures logs from the tests (and the pipewire daemon, if
|
|
* applicable) and collects the output into YAML files printed to `stderr`.
|
|
*
|
|
* ## Tests
|
|
*
|
|
* A `pwtest` test is declared with the `PWTEST()` macro and must return one of
|
|
* the `pwtest` status codes. Those codes are:
|
|
* - \ref PWTEST_PASS for a successful test
|
|
* - \ref PWTEST_FAIL for a test case failure. Usually you should not return this
|
|
* value but rely on the `pwtest` macros to handle this case.
|
|
* - \ref PWTEST_SKIP to skip the current test
|
|
* - \ref PWTEST_SYSTEM_ERROR in case of an error that would cause the test to not run propertly. This is not a test case failure but some required precondition not being met.
|
|
*
|
|
* ```c
|
|
* #include "pwtest.h"
|
|
*
|
|
* PWTEST(some_test)
|
|
* {
|
|
* int var = 10;
|
|
* const char *str = "foo";
|
|
*
|
|
* if (access("/", R_OK))
|
|
* pwtest_error_with_message("Oh dear, no root directory?");
|
|
*
|
|
* if (today_is_monday)
|
|
* return PWTEST_SKIP;
|
|
*
|
|
* pwtest_int_lt(var, 20);
|
|
* pwtest_ptr_notnull(&var);
|
|
* pwtest_str_ne(str, "bar");
|
|
*
|
|
* return PWTEST_PASS;
|
|
* }
|
|
* ...
|
|
* ```
|
|
*
|
|
* `pwtest` provides comparision macros for most basic data types with the `lt`,
|
|
* `le`, `eq`, `gt`, `ge` suffixes (`<, <=, ==, >, >=`). Tests usually should not
|
|
* return `PWTEST_FAIL` directly, use the `pwtest_fail()` macros if .
|
|
*
|
|
* By default, a test runs in a forked process, any changes to the
|
|
* process'environment, etc. are discarded in the next test.
|
|
*
|
|
* ## Suites
|
|
*
|
|
* Tests are grouped into suites and declared with the PWTEST_SUITE() macro.
|
|
* Each test must be added with the required arguments, it is acceptable to
|
|
* add the same test multiple times with different arguments.
|
|
*
|
|
* ```c
|
|
* ...
|
|
* PWTEST_SUITE(misc)
|
|
* {
|
|
* if (today_is_monday)
|
|
* return PWTEST_SKIP;
|
|
*
|
|
* // simple test
|
|
* pwtest_add(some_test, PWTEST_NOARG);
|
|
* // starts with its own pipewire daemon instance
|
|
* pwtest_add(some_test, PWTEST_ARG_DAEMON);
|
|
*
|
|
* return PWTEST_SUCCESS;
|
|
* }
|
|
* ```
|
|
* For a list of potential arguments, see \ref pwtest_arg and the
|
|
* `test-examples.c` file in the source directory.
|
|
*
|
|
* Suites are auto-discovered, they do not have to be manually added to a test run.
|
|
*
|
|
* ## Running tests
|
|
*
|
|
* The `pwtest` framework is built into each test binary, so just execute the
|
|
* matching binary. See the `--help` output for the full argument list.
|
|
*
|
|
* The most useful arguments when running the test suite:
|
|
* - `--verbose` to enable logs even when tests pass or are skipped
|
|
* - `--filter-test=glob`, `--filter-suite=glob` uses an `fnmatch()` glob to limit which tests or suites are run
|
|
* - `--no-fork` - see "Debugging test-case failures"
|
|
*
|
|
* ## Debugging test-case failures
|
|
*
|
|
* To debug a single test, disable forking and run the test through gdb:
|
|
*
|
|
* ```
|
|
* $ gdb path/to/test
|
|
* (gdb) break test_function_name
|
|
* Breakpoint 1 at 0xfffffffffffff: file ../test/test-file.c, line 123
|
|
* (gdb) r --no-fork --filter-test=test_function_name
|
|
* ```
|
|
* Disabling forking makes it easy to debug but should always be used with
|
|
* `--filter-test`. Any test that modifies its environment will affect
|
|
* subsequent tests and may invalidate the test results.
