commit 3ce3984772b673b82a87aded1bc8a1a0f1969e19
Author: dana koch <dsk(a)google.com>
Date: Tue Apr 15 22:20:34 2014 +1000
Uplift status.c unit test coverage with new test cases and macros.
A new set of unit test cases are provided, as well as introducing
an alternative paradigm and macros to support it. Primarily, each test
case is given its own namespace, in order to isolate tests from each
other. We do this by in the usual fashion, by appending module and
submodule names to our symbols. New macros assist by reducing friction
for this and other tasks, like overriding a function in the global
namespace with one in the current namespace, or declaring integer
variables to assist tracking how many times a mock has been called.
A set of tests for a small-scale module has been included in this
commit, in order to highlight how the paradigm can be used. This
suite gives 100% coverage to status.c in test execution.

+ * These macros are helpful for streamlining the authorship of several test
+ * cases that use mocks.
+ *
+ * The pattern is as follows.
+ * * Declare a top level namespace:
+ * #define NS_MODULE foo
+ *
+ * * For each test case you want to write, create a new submodule in the
+ * namespace. All mocks and other information should belong to a single
+ * submodule to avoid interference with other test cases.
+ * You can simply name the submodule after the function in the module you
+ * are testing:
+ * #define NS_SUBMODULE some_function
+ * or, if you're wanting to write several tests against the same function,
+ * ie., you are testing an aspect of that function, you can use:
+ * #define NS_SUBMODULE ASPECT(some_function, behavior)
+ *
+ * * Declare all the mocks you will use. The NS_DECL macro serves to declare
+ * the mock in the current namespace (defined by NS_MODULE and NS_SUBMODULE).
+ * It behaves like MOCK_DECL:
+ * NS_DECL(int, dependent_function, (void *));
+ * Here, dependent_function must be declared and implemented with the
+ * MOCK_DECL and MOCK_IMPL macros. The NS_DECL macro also defines an integer
+ * global for use for tracking how many times a mock was called, and can be
+ * accessed by CALLED(mock_name). For example, you might put
+ * CALLED(dependent_function)++;
+ * in your mock body.
+ *
+ * * Define a function called NS(main) that will contain the body of the
+ * test case. The NS macro can be used to reference a name in the current
+ * namespace.
+ *
+ * * In NS(main), indicate that a mock function in the current namespace,
+ * declared with NS_DECL is to override that in the global namespace,
+ * with the NS_MOCK macro:
+ * NS_MOCK(dependent_function)
+ * Unmock with:
+ * NS_UNMOCK(dependent_function)
+ *
+ * * Define the mocks with the NS macro, eg.,
+ * int
+ * NS(dependent_function)(void *)
+ * {
+ * CALLED(dependent_function)++;
+ * }
+ *
+ * * In the struct testcase_t array, you can use the TEST_CASE and
+ * TEST_CASE_ASPECT macros to define the cases without having to do so
+ * explicitly nor without having to reset NS_SUBMODULE, eg.,
+ * struct testcase_t foo_tests[] = {
+ * TEST_CASE_ASPECT(some_function, behavior),
+ * ...
+ * END_OF_TESTCASES
+ * which will define a test case named "some_function__behavior".
