@section zunitc_overview Overview
A simple test framework in plain C suitable for basic unit and integration testing.
The main rationale for creating this framework was to have a simple to use testing
framework with tests implemented in C using common patterns and under a
compatible license. The structure of the test code and macro use is intended to
follow common patterns established by frameworks such as Boost Test and Google Test.
To get started, one or more tests should be defined via ZUC_TEST() and/or
ZUC_TEST_F(), which set up automatic test registration via gcc extensions.
To actually execute tests, ZUC_RUN_TESTS() should be called.
Tests can use several ZUC_ASSERT_* or ZUC_ASSERTG_* checks to validate
conditions. The ZUC_ASSERT_* ones upon failure will mark the current test
as failing and immediatly execute a return. On the other hand, the
ZUC_ASSERTG_* tests will mark the current test as failed and then execute a
'goto' targeting the specified label.
The set of fatal test checks are
- ZUC_ASSERT_TRUE()
- ZUC_ASSERT_FALSE()
- ZUC_ASSERT_NULL()
- ZUC_ASSERT_NOT_NULL()
- ZUC_ASSERT_EQ()
- ZUC_ASSERT_NE()
- ZUC_ASSERT_LT()
- ZUC_ASSERT_LE()
- ZUC_ASSERT_GT()
- ZUC_ASSERT_GE()
- ZUC_ASSERT_STREQ()
- ZUC_ASSERT_STRNE()
and
- ZUC_ASSERTG_TRUE()
- ZUC_ASSERTG_FALSE()
- ZUC_ASSERTG_NULL()
- ZUC_ASSERTG_NOT_NULL()
- ZUC_ASSERTG_EQ()
- ZUC_ASSERTG_NE()
- ZUC_ASSERTG_LT()
- ZUC_ASSERTG_LE()
- ZUC_ASSERTG_GT()
- ZUC_ASSERTG_GE()
- ZUC_ASSERTG_STREQ()
- ZUC_ASSERTG_STRNE()
Unconditional test values for logging and termination are
- ZUC_SKIP()
- ZUC_FATAL()
Unconditional message logging for failure cases only is
- ZUC_TRACEPOINT()
@section zunitc_execution Controlling Execution
To control execution, the various zuc_set_* functions can be called
before invoking ZUC_RUN_TESTS().
@subsection zunitc_execution_commandline Commandline Parameters
The current implementation defers processing of command-line parameters
to the main application hosting the testing. It is possible that a
helper to process certain parameters may be added.
@subsection zunitc_execution_matching Matching Patterns for Tests
The function zuc_set_filter() can be used to specify a pattern for
matching or excluding tests from a run. The general form is
match1[:match2[:match3..n]][:-exclude1[:exclude2[:exclude3..n]]]
@subsection zunitc_execution_wildcards Matching Wildcards
Wildcards can be used in the match/exclude patterns and recognize the
following two special characters:
- '*' matches any number of characters including zero.
- '?' matches any single character.
Calling zuc_list_tests() after zuc_set_filter() can be done to show the
effects of the matching without needing to actually run tests.
@subsection zunitc_execution_repeat Repeating Tests
Setting the repeat count higher than 1 ( via zuc_set_repeat() ) will
cause the tests to be executed several times in a row. This can be
useful for stress testing, checking for leaks, etc.
@subsection zunitc_execution_randomize Randomizing Tests
Test ordering can be randomized by setting a non-zero positive value to
zuc_set_random(). Setting it to 1 will cause the framework to pick a
random seed based on the time. A value greater than 1 will be taken as a
random seed itself. And setting it to 0 will disable randomization and
allow the test to be executed in their natural ordering.
@section zunitc_fixtures Fixtures
Per-suite and per-test setup and teardown fixtures can be implemented by
defining an instance of struct zuc_fixture and using it as the first
parameter to ZUC_TEST_F().
@section zunitc_functions Functions
- ZUC_TEST()
- ZUC_TEST_F()
- ZUC_RUN_TESTS()
- zuc_cleanup()
- zuc_list_tests()
- zuc_set_filter()
- zuc_set_random()
- zuc_set_spawn()
- zuc_set_output_tap()
- zuc_set_output_junit()
- zuc_has_skip()
- zuc_has_failure()
