Each test suite is a `*.c` +file with a descriptive name: this encourages modularity. + +Each test suite has optional initialize and cleanup methods. These methods +will be called before and after running **each** test in the suite, even if +such test fails. As a rule of thumb, if a test needs a different initializer +or cleanup method than another test in the same module, that means it +doesn't belong in that module. Keep that in mind when grouping tests +together. + +The `initialize` and `cleanup` methods have the following syntax, with +`suitename` being the current suite name, e.g. `adding` for the `adding.c` +suite. + +~~~~ c +void test_suitename__initialize(void) +{ + /* init */ +} + +void test_suitename__cleanup(void) +{ + /* cleanup */ +} +~~~~ + +These methods are encouraged to use static, global variables to store the state +that will be used by all tests inside the suite. + +~~~~ c +static git_repository *_repository; + +void test_status__initialize(void) +{ + create_tmp_repo(STATUS_REPO); + git_repository_open(_repository, STATUS_REPO); +} + +void test_status__cleanup(void) +{ + git_repository_close(_repository); + git_path_rm(STATUS_REPO); +} + +void test_status__simple_test(void) +{ + /* do something with _repository */ +} +~~~~ + +Writing the actual tests is just as straightforward. Tests have the +`void test_suitename__test_name(void)` signature, and they should **not** +be static. Clar will automatically detect and list them. + +Tests are run as they appear on their original suites: they have no return +value. A test is considered "passed" if it doesn't raise any errors. Check +the "Clar API" section to see the various helper functions to check and +raise errors during test execution. + +__Caution:__ If you use assertions inside of `test_suitename__initialize`, +make sure that you do not rely on `__initialize` being completely run +inside your `test_suitename__cleanup` function. Otherwise you might +encounter ressource cleanup twice. + +## How does Clar work? + +To use Clar: + +1. copy the Clar boilerplate to your test directory +2. copy (and probably modify) the sample `main.c` (from + `$CLAR_PATH/test/main.c.sample`) +3. run the Clar mixer (a.k.a. `generate.py`) to scan your test directory and + write out the test suite metadata. +4. compile your test files and the Clar boilerplate into a single test + executable +5. run the executable to test! + +The Clar boilerplate gives you a set of useful test assertions and features +(like accessing or making sandbox copies of fixture data). It consists of +the `clar.c` and `clar.h` files, plus the code in the `clar/` subdirectory. +You should not need to edit these files. + +The sample `main.c` (i.e. `$CLAR_PATH/test/main.c.sample`) file invokes +`clar_test(argc, argv)` to run the tests. Usually, you will edit this file +to perform any framework specific initialization and teardown that you need. + +The Clar mixer (`generate.py`) recursively scans your test directory for +any `.c` files, parses them, and writes the `clar.suite` file with all of +the metadata about your tests. When you build, the `clar.suite` file is +included into `clar.c`. + +The mixer can be run with **Python 2.5, 2.6, 2.7, 3.0, 3.1, 3.2 and PyPy 1.6**. + +Commandline usage of the mixer is as follows: + + $ ./generate.py . + +Where `.` is the folder where all the test suites can be found. The mixer +will automatically locate all the relevant source files and build the +testing metadata. The metadata will be written to `clar.suite`, in the same +folder as all the test suites. This file is included by `clar.c` and so +must be accessible via `#include` when building the test executable. + + $ gcc -I. clar.c main.c suite1.c test2.c -o run_tests + +**Note that the Clar mixer only needs to be ran when adding new tests to a +suite, in order to regenerate the metadata**. As a result, the `clar.suite` +file can be checked into version control if you wish to be able to build +your test suite without having to re-run the mixer. + +This is handy when e.g. generating tests in a local computer, and then +building and testing them on an embedded device or a platform where Python +is not available. + +### Fixtures + +Clar can create sandboxed fixtures for you to use in your test. You'll need to compile *clar.c* with an additional `CFLAG`, `-DCLAR_FIXTURE_PATH`. This should be an absolute path to your fixtures directory. + +Once that's done, you can use the fixture API as defined below. + +## The Clar API + +Clar makes the following methods available from all functions in a test +suite. + +- `cl_must_pass(call)`, `cl_must_pass_(call, message)`: Verify that the given + function call passes, in the POSIX sense (returns a value greater or equal + to 0). + +- `cl_must_fail(call)`, `cl_must_fail_(call, message)`: Verify that the given + function call fails, in the POSIX sense (returns a value less than 0). + +- `cl_assert(expr)`, `cl_assert_(expr, message)`: Verify that `expr` is true. + +- `cl_check_pass(call)`, `cl_check_pass_(call, message)`: Verify that the + given function call passes, in the POSIX sense (returns a value greater or + equal to 0). If the function call doesn't succeed, a test failure will be + logged but the test's execution will continue. + +- `cl_check_fail(call)`, `cl_check_fail_(call, message)`: Verify that the + given function call fails, in the POSIX sense (returns a value less than + 0). If the function call doesn't fail, a test failure will be logged but + the test's execution will continue. + +- `cl_check(expr)`: Verify that `expr` is true. If `expr` is not + true, a test failure will be logged but the test's execution will continue. + +- `cl_fail(message)`: Fail the current test with the given message. + +- `cl_warning(message)`: Issue a warning. This warning will be + logged as a test failure but the test's execution will continue. + +- `cl_set_cleanup(void (*cleanup)(void *), void *opaque)`: Set the cleanup + method for a single test. This method will be called with `opaque` as its + argument before the test returns (even if the test has failed). + If a global cleanup method is also available, the local cleanup will be + called first, and then the global. + +- `cl_assert_equal_i(int,int)`: Verify that two integer values are equal. + The advantage of this over a simple `cl_assert` is that it will format + a much nicer error report if the values are not equal. + +- `cl_assert_equal_s(const char *,const char *)`: Verify that two strings + are equal. The expected value can also be NULL and this will correctly + test for that. + +- `cl_fixture_sandbox(const char *)`: Sets up a sandbox for a fixture + so that you can mutate the file directly. + +- `cl_fixture_cleanup(const char *)`: Tears down the previous fixture + sandbox. + +- `cl_fixture(const char *)`: Gets the full path to a fixture file. + +Please do note that these methods are *always* available whilst running a +test, even when calling auxiliary/static functions inside the same file. + +It's strongly encouraged to perform test assertions in auxiliary methods, +instead of returning error values. This is considered good Clar style. + +Style Example: + +~~~~ c +/* + * Bad style: auxiliary functions return an error code + */ + +static int check_string(const char *str) +{ + const char *aux = process_string(str); + + if (aux == NULL) + return -1; + + return strcmp(my_function(aux), str) == 0 ? 0 : -1; +} + +void test_example__a_test_with_auxiliary_methods(void) +{ + cl_must_pass_( + check_string("foo"), + "String differs after processing" + ); + + cl_must_pass_( + check_string("bar"), + "String differs after processing" + ); +} +~~~~ + +~~~~ c +/* + * Good style: auxiliary functions perform assertions + */ + +static void check_string(const char *str) +{ + const char *aux = process_string(str); + + cl_assert_( + aux != NULL, + "String processing failed" + ); + + cl_assert_( + strcmp(my_function(aux), str) == 0, + "String differs after processing" + ); +} + +void test_example__a_test_with_auxiliary_methods(void) +{ + check_string("foo"); + check_string("bar"); +} +~~~~ + +About Clar +========== + +Clar has been written from scratch by [Vicent Martí](https://github.com/vmg), +to replace the old testing framework in [libgit2][libgit2]. + +Do you know what languages are *in* on the SF startup scene?
