+Come out and Clar
+=================
+
+In Catalan, "clar" means clear, easy to perceive. Using clar will make it
+easy to test and make clear the quality of your code.
+
+> _Historical note_
+>
+> Originally the clar project was named "clay" because the word "test" has its
+> roots in the latin word *"testum"*, meaning "earthen pot", and *"testa"*,
+> meaning "piece of burned clay"?
+>
+> This is because historically, testing implied melting metal in a pot to
+> check its quality. Clay is what tests are made of.
+
+## Quick Usage Overview
+
+Clar is a minimal C unit testing framework. It's been written to replace the
+old framework in [libgit2][libgit2], but it's both very versatile and
+straightforward to use.
+
+Can you count to funk?
+
+- **Zero: Initialize test directory**
+
+ ~~~~ sh
+ $ mkdir tests
+ $ cp -r $CLAR_ROOT/clar* tests
+ $ cp $CLAR_ROOT/test/clar_test.h tests
+ $ cp $CLAR_ROOT/test/main.c.sample tests/main.c
+ ~~~~
+
+- **One: Write some tests**
+
+ File: tests/adding.c:
+
+ ~~~~ c
+ /* adding.c for the "Adding" suite */
+ #include "clar.h"
+
+ static int *answer;
+
+ void test_adding__initialize(void)
+ {
+ answer = malloc(sizeof(int));
+ cl_assert_(answer != NULL, "No memory left?");
+ *answer = 42;
+ }
+
+ void test_adding__cleanup(void)
+ {
+ free(answer);
+ }
+
+ void test_adding__make_sure_math_still_works(void)
+ {
+ cl_assert_(5 > 3, "Five should probably be greater than three");
+ cl_assert_(-5 < 2, "Negative numbers are small, I think");
+ cl_assert_(*answer == 42, "The universe is doing OK. And the initializer too.");
+ }
+ ~~~~~
+
+- **Two: Build the test executable**
+
+ ~~~~ sh
+ $ cd tests
+ $ $CLAR_PATH/generate.py .
+ Written `clar.suite` (1 suites)
+ $ gcc -I. clar.c main.c adding.c -o testit
+ ~~~~
+
+- **Funk: Funk it.**
+
+ ~~~~ sh
+ $ ./testit
+ ~~~~
+
+## The Clar Test Suite
+
+Writing a test suite is pretty straightforward. 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");
+}
