Description

GLib provides a framework for writing and maintaining unit tests in parallel to the code they are testing. The API is designed according to established concepts found in the other test frameworks (JUnit, NUnit, RUnit), which in turn is based on smalltalk unit testing concepts.

Test case

Tests (test methods) are grouped together with their fixture into test cases.

Fixture

A test fixture consists of fixture data and setup and teardown methods to establish the environment for the test functions. We use fresh fixtures, i.e. fixtures are newly set up and torn down around each test invocation to avoid dependencies between tests.

Test suite

Test cases can be grouped into test suites, to allow subsets of the available tests to be run. Test suites can be grouped into other test suites as well.

The API is designed to handle creation and registration of test suites and test cases implicitly. A simple call like

1
g_test_add_func ("/misc/assertions", test_assertions);

creates a test suite called "misc" with a single test case named "assertions", which consists of running the test_assertions function.

In addition to the traditional g_assert(), the test framework provides an extended set of assertions for string and numerical comparisons: g_assert_cmpfloat(), g_assert_cmpint(), g_assert_cmpuint(), g_assert_cmphex(), g_assert_cmpstr(). The advantage of these variants over plain g_assert() is that the assertion messages can be more elaborate, and include the values of the compared entities.

GLib ships with two utilities called gtester and gtester-report to facilitate running tests and producing nicely formatted test reports.

g_test_init ()

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

Initialize the GLib testing framework, e.g. by seeding the test random number generator, the name for g_get_prgname() and parsing test related command line args. So far, the following arguments are understood:

-l

list test cases available in a test executable.

--seed=RANDOMSEED

provide a random seed to reproduce test runs using random numbers.

--verbose

run tests verbosely.

-q, --quiet

run tests quietly.

-p TESTPATH

execute all tests matching TESTPATH.

-m {perf|slow|thorough|quick}

execute tests according to these test modes:

perf

performance tests, may take long and report results.

slow, thorough

slow and thorough tests, may take quite long and maximize coverage.

quick

quick tests, should run really quickly and give good coverage.

--debug-log

debug test logging output.

-k, --keep-going

gtester-specific argument.

--GTestLogFD N

gtester-specific argument.

--GTestSkipCount N

gtester-specific argument.

argc :

Address of the argc parameter of the main() function. Changed if any arguments were handled.

argv :

Address of the argv parameter of main(). Any parameters understood by g_test_init() stripped before return.

... :

Reserved for future extension. Currently, you must pass NULL.

Since 2.16


g_test_quick

#define             g_test_quick()

Returns TRUE if tests are run in quick mode.


g_test_slow

#define             g_test_slow()

Returns TRUE if tests are run in slow mode.


g_test_thorough

#define             g_test_thorough()

Returns TRUE if tests are run in thorough mode.


g_test_perf

#define             g_test_perf()

Returns TRUE if tests are run in performance mode.


g_test_verbose

#define             g_test_verbose()

Returns TRUE if tests are run in verbose mode.


g_test_quiet

#define             g_test_quiet()

Returns TRUE if tests are run in quiet mode.


g_test_run ()

int                 g_test_run                          (void);

Runs all tests under the toplevel suite which can be retrieved with g_test_get_root(). Similar to g_test_run_suite(), the test cases to be run are filtered according to test path arguments (-p testpath) as parsed by g_test_init(). g_test_run_suite() or g_test_run() may only be called once in a program.

Returns :

0 on success

Since 2.16


g_test_add_func ()

void                g_test_add_func                     (const char *testpath,
                                                         void (test_funcvoid) ());

Create a new test case, similar to g_test_create_case(). However the test is assumed to use no fixture, and test suites are automatically created on the fly and added to the root fixture, based on the slash-separated portions of testpath.

testpath :

Slash-separated test case path name for the test.

Since 2.16


g_test_add_data_func ()

void                g_test_add_data_func                (const char *testpath,
                                                         gconstpointer test_data,

Create a new test case, similar to g_test_create_case(). However the test is assumed to use no fixture, and test suites are automatically created on the fly and added to the root fixture, based on the slash-separated portions of testpath. The test_data argument will be passed as first argument to test_func.

testpath :

Slash-separated test case path name for the test.

test_data :

Test data argument for the test function.

gconstpointer :

Since 2.16


g_test_add()

#define             g_test_add(testpath, Fixture, tdata, fsetup, ftest, fteardown)

Hook up a new test case at testpath, similar to g_test_add_func(). A fixture data structure with setup and teardown function may be provided though, similar to g_test_create_case(). g_test_add() is implemented as a macro, so that the fsetup(), ftest() and fteardown() callbacks can expect a Fixture pointer as first argument in a type safe manner.

testpath :

The test path for a new test case.

Fixture :

The type of a fixture data structure.

tdata :

Data argument for the test functions.

fsetup :

The function to set up the fixture data.

ftest :

The actual test function.

fteardown :

The function to tear down the fixture data.

Since 2.16


g_test_message ()

void                g_test_message                      (const char *format,
                                                         ...);

Add a message to the test report.

format :

the format string

... :

g_test_bug_base ()

void                g_test_bug_base                     (const char *uri_pattern);

Specify the base URI for bug reports.

The base URI is used to construct bug report messages for g_test_message() when g_test_bug() is called. Calling this function outside of a test case sets the default base URI for all test cases. Calling it from within a test case changes the base URI for the scope of the test case only. Bug URIs are constructed by appending a bug specific URI portion to uri_pattern, or by replacing the special string 's' within uri_pattern if that is present.

uri_pattern :

the base pattern for bug URIs

Since 2.16


g_test_bug ()

void                g_test_bug                          (const char *bug_uri_snippet);

This function adds a message to test reports that associates a bug URI with a test case. Bug URIs are constructed from a base URI set with g_test_bug_base() and bug_uri_snippet.

bug_uri_snippet :

Bug specific bug tracker URI portion.

Since 2.16


GTestLogFatalFunc ()

                                                         gpointer user_data);

Specifies the prototype of fatal log handler functions.

log_domain :

the log domain of the message

log_level :

the log level of the message (including the fatal and recursion flags)

message :

the message to process

user_data :

user data, set in g_test_log_set_fatal_handler()

Returns :

TRUE if the program should abort, FALSE otherwise

Since 2.22


g_test_log_set_fatal_handler ()

void                g_test_log_set_fatal_handler        (GTestLogFatalFunc log_func,
                                                         gpointer user_data);

Installs a non-error fatal log handler which can be used to decide whether log messages which are counted as fatal abort the program.

The use case here is that you are running a test case that depends on particular libraries or circumstances and cannot prevent certain known critical or warning messages. So you install a handler that compares the domain and message to precisely not abort in such a case.

Note that the handler is reset at the beginning of any test case, so you have to set it inside each test function which needs the special behavior.

This handler has no effect on g_error messages.

log_func :

the log handler function.

user_data :

data passed to the log handler.

Since 2.22


g_test_timer_start ()

void                g_test_timer_start                  (void);

double              g_test_timer_elapsed                (void);

Get the time since the last start of the timer with g_test_timer_start().

Returns :

the time since the last start of the timer, as a double

Since 2.16


g_test_timer_last ()

double              g_test_timer_last                   (void);

Enqueue a pointer to be released with g_free() during the next teardown phase. This is equivalent to calling g_test_queue_destroy() with a destroy callback of g_free().

gfree_pointer :

the pointer to be stored.

Since 2.16


g_test_queue_destroy ()

void                g_test_queue_destroy                (GDestroyNotify destroy_func,
                                                         gpointer destroy_data);

This function enqueus a callback @destroy_func() to be executed during the next test case teardown phase. This is most useful to auto destruct allocted test resources at the end of a test run. Resources are released in reverse queue order, that means enqueueing callback A before callback B will cause B() to be called before A() during teardown.

destroy_func :

Destroy callback for teardown phase.

destroy_data :

Destroy callback data.

Since 2.16


g_test_queue_unref()

#define             g_test_queue_unref(gobject)

enum GTestTrapFlags

typedef enum {
  G_TEST_TRAP_SILENCE_STDOUT    = 1 << 7,
  G_TEST_TRAP_SILENCE_STDERR    = 1 << 8,
  G_TEST_TRAP_INHERIT_STDIN     = 1 << 9
} GTestTrapFlags;

Test traps are guards around forked tests. These flags determine what traps to set.

G_TEST_TRAP_SILENCE_STDOUT

Redirect stdout of the test child to /dev/null so it cannot be observed on the console during test runs. The actual output is still captured though to allow later tests with g_test_trap_assert_stdout().

G_TEST_TRAP_SILENCE_STDERR

Redirect stderr of the test child to /dev/null so it cannot be observed on the console during test runs. The actual output is still captured though to allow later tests with g_test_trap_assert_stderr().

G_TEST_TRAP_INHERIT_STDIN

If this flag is given, stdin of the forked child process is shared with stdin of its parent process. It is redirected to /dev/null otherwise.

g_test_trap_fork ()

gboolean            g_test_trap_fork                    (guint64 usec_timeout,
                                                         GTestTrapFlags test_trap_flags);

Fork the current test program to execute a test case that might not return or that might abort. The forked test case is aborted and considered failing if its run time exceeds usec_timeout.

The forking behavior can be configured with the GTestTrapFlags flags.

In the following example, the test code forks, the forked child process produces some sample output and exits successfully. The forking parent process then asserts successful child program termination and validates child program outputs.

g_assert()

#define             g_assert(expr)

Debugging macro to terminate the application if the assertion fails. If the assertion fails (i.e. the expression is not true), an error message is logged and the application is terminated.

The macro can be turned off in final releases of code by defining G_DISABLE_ASSERT when compiling the application.

expr :

the expression to check.

g_assert_not_reached

#define             g_assert_not_reached()

Debugging macro to terminate the application if it is ever reached. If it is reached, an error message is logged and the application is terminated.

The macro can be turned off in final releases of code by defining G_DISABLE_ASSERT when compiling the application.


g_assert_cmpstr()

#define             g_assert_cmpstr(s1, cmp, s2)

Debugging macro to terminate the application with a warning message if a string comparison fails. The strings are compared using g_strcmp0().

The effect of g_assert_cmpstr (s1, op, s2) is the same as g_assert (g_strcmp0 (s1, s2) op 0). The advantage of this macro is that it can produce a message that includes the actual values of s1 and s2.

g_assert_cmpuint()

#define             g_assert_cmpuint(n1, cmp, n2)

Debugging macro to terminate the application with a warning message if an unsigned integer comparison fails.

The effect of g_assert_cmpuint (n1, op, n2) is the same as g_assert (n1 op n2). The advantage of this macro is that it can produce a message that includes the actual values of n1 and n2.

n1 :

an unsigned integer

cmp :

The comparison operator to use. One of ==, !=, <, >, <=, >=.

n2 :

another unsigned integer

Since 2.16


g_assert_cmphex()

#define             g_assert_cmphex(n1, cmp, n2)

Debugging macro to terminate the application with a warning message if an unsigned integer comparison fails. This is a variant of g_assert_cmpuint() that displays the numbers in hexadecimal notation in the message.

n1 :

an unsigned integer

cmp :

The comparison operator to use. One of ==, !=, <, >, <=, >=.

n2 :

another unsigned integer

Since 2.16


g_assert_cmpfloat()

#define             g_assert_cmpfloat(n1,cmp,n2)

Debugging macro to terminate the application with a warning message if a floating point number comparison fails.

g_assert_no_error()

#define             g_assert_no_error(err)

Debugging macro to terminate the application with a warning message if a method has returned a GError.

The effect of g_assert_no_error (err) is the same as g_assert (err == NULL). The advantage of this macro is that it can produce a message that includes the error message and code.

err :

a GError, possibly NULL

Since 2.20


g_assert_error()

#define             g_assert_error(err, dom, c)

Debugging macro to terminate the application with a warning message if a method has not returned the correct GError.

The effect of g_assert_error (err, dom, c) is the same as g_assert (err != NULL && err->domain == dom && err->code == c). The advantage of this macro is that it can produce a message that includes the incorrect error message and code.

This can only be used to test for a specific error. If you want to test that err is set, but don't care what it's set to, just use g_assert (err != NULL)

err :

a GError, possibly NULL

Create a new GTestCase, named test_name, this API is fairly low level, calling g_test_add() or g_test_add_func() is preferable. When this test is executed, a fixture structure of size data_size will be allocated and filled with 0s. Then data_setup() is called to initialize the fixture. After fixture setup, the actual test function data_test() is called. Once the test run completed, the fixture structure is torn down by calling data_teardown() and after that the memory is released.

Splitting up a test run into fixture setup, test function and fixture teardown is most usful if the same fixture is used for multiple tests. In this cases, g_test_create_case() will be called with the same fixture, but varying test_name and data_test arguments.

test_name :

the name for the test case

data_size :

the size of the fixture data structure

test_data :

test data argument for the test functions
