Function

GLibtest_init

since: 2.16

Declaration [src] 

void
g_test_init (
  int* argc,
  char*** argv,
  ...
)

Description [src]

Initializes the GLib testing framework.

This includes seeding the test random number generator, setting the program name, and parsing test-related commandline args.

This should be called before calling any other g_test_*() functions.

The following arguments are understood:

  • -l: List test cases available in a test executable.
  • --seed=SEED: Provide a random seed to reproduce test runs using random numbers.
  • --verbose: Run tests verbosely.
  • -q, --quiet: Run tests quietly.
  • -p PATH: Execute all tests matching the given path.
  • -s PATH: Skip all tests matching the given path. This can also be used to force a test to run that would otherwise be skipped (ie, a test whose name contains “/subprocess”).
  • -m {perf|slow|thorough|quick|undefined|no-undefined}: Execute tests according to these test modes:

perf: Performance tests, may take long and report results (off by default).

slow, thorough: Slow and thorough tests, may take quite long and maximize coverage (off by default).

quick: Quick tests, should run really quickly and give good coverage (the default).

undefined: Tests for undefined behaviour, may provoke programming errors under g_test_trap_subprocess() or g_test_expect_message() to check that appropriate assertions or warnings are given (the default).

no-undefined: Avoid tests for undefined behaviour.

  • --debug-log: Debug test logging output.

Any parsed arguments are removed from argv, and argc is adjust accordingly.

The following options are supported:

  • G_TEST_OPTION_NO_PRGNAME: Causes g_test_init() to not call g_set_prgname(). Since. 2.84
  • G_TEST_OPTION_ISOLATE_DIRS: Creates a unique temporary directory for each unit test and sets XDG directories to point there for the duration of the unit test. See G_TEST_OPTION_ISOLATE_DIRS.
  • G_TEST_OPTION_NONFATAL_ASSERTIONS: This has the same effect as g_test_set_nonfatal_assertions(). Since 2.84

Since 2.58, if tests are compiled with G_DISABLE_ASSERT defined, g_test_init() will print an error and exit. This is to prevent no-op tests from being executed, as g_assert() is commonly (erroneously) used in unit tests, and is a no-op when compiled with G_DISABLE_ASSERT. Ensure your tests are compiled without G_DISABLE_ASSERT defined.
