42 \section UnitTestAPIUsage How to Use the Unit Test API
44 \subsection DefineTest Define a Test
46 Create a callback function for the test using the AST_TEST_DEFINE macro.
48 Each defined test has three arguments avaliable to it's test code.
49 \param struct ast_test_info *info
50 \param enum ast_test_command cmd
51 \param struct ast_test *test
53 While these arguments are not visible they are passed to every test function
54 defined using the AST_TEST_DEFINE macro.
56 Below is an example of how to define and write a test function.
59 AST_TEST_DEFINE(sample_test_cb) \\The name of the callback function
60 { \\The the function's body
63 info->name = "sample_test";
64 info->category = "main/test/";
65 info->summary = "sample test for example purpose";
66 info->description = "This demonstrates how to initialize a test function";
68 return AST_TEST_NOT_RUN;
76 if (fail) { \\ the following is just some example logic
77 ast_test_status_update(test, "an error occured because...");
78 res = AST_RESULT_FAIL;
82 return res; \\ result must be of type enum ast_test_result_state
86 Details of the test execution, especially failure details, should be provided
87 by using the ast_test_status_update() function.
89 \subsection RegisterTest Register a Test
91 Register the test using the AST_TEST_REGISTER macro.
93 AST_TEST_REGISTER uses the callback function to retrieve all the information
94 pertaining to a test, so the callback function is the only argument required
95 for registering a test.
97 AST_TEST_REGISTER(sample_test_cb); \\ Test callback function defined by AST_TEST_DEFINE
99 Tests are unregestered by using the AST_TEST_UNREGISTER macro.
101 AST_TEST_UNREGISTER(sample_test_cb); \\ Remove a registered test by callback function
103 \subsection ExecuteTest Execute a Test
105 Execute and generate test results via CLI commands
109 'test show registered all' will show every registered test.
110 'test execute all' will execute every registered test.
111 'test show results all' will show detailed results for ever executed test
112 'test generate results xml' will generate a test report in xml format
113 'test generate results txt' will generate a test report in txt format
