This type of testing is very common in Java community. The benefits are +a) that problems are found very early in the development process, +b) it simplifies the integration of different modules because unit testing +established a basic trust in the small units themselves, c) it serves as +documentation about the expected behavior, d) enables easier code reuse because +code is already tested via two different code paths [Wikipedia]. + +The unit test code is stored in src/test/unit. The directory contains the +modified cmockery library, all mock source files currently in use (mock) and a +directory test, which contains all test code. + +The different test executables can be found in the subdirectories of the +directory test. By the design the used test library cmockery works, a test +executable can only focus on a set of source files. We call this portion the +System Under Test (SUT). We will talk more about the System Under Test later. +For now, it is important to know that the SUT is the port of code tested in a +test and that each SUT has its own test executable. Usually a SUT consists of a +single file, e.g. heapam.c, but it can also consist of multiple related files. + +== Test Development Process == + +The development of a new test consists of multiple steps: + +1. Selecting an appropriate System Under Test. Often the SUT consists of the + source file of the function to test. But exceptions from this rule of thumb + are possible. There are already tests with the given SUT, the new test can + be added to the existing executable. Step 2 can be skipped in this case. + +2. Creating the SUT test executable. If the SUT does not exist, a new test + executable needs to be created: + + - Create a new test executable directory, usually named after the SUT source + file(s) and add a Makefile. The directory template contains template files + for the Makefile and the README file. + + > TARGETS=SOMETHING_test + > include ../Makefile.all + > include ${CMOCKERY_DIR}/Makefile + > include ${MOCK_DIR}/Makefile + + > MOCK_OBJS= + + > include ../Makefile.all2 + + - Change the TARGETS, and _REAL_OBJS variables in the + Makefile. TARGETS is usually straightforward to set. + + By default, the test program is linked with mock versions of most + backend files. The _REAL_OBJS needs to list any files + that should *not* be mocked, for which the real file should linked + in instead. + + - Create a new test source file, also usually named after the SUT. An + example is heapam_test.c in the heapam SUT directory. In the beginning + the test source file consists only of the main function. + + Here is an example: + + > #include + > #include + > #include + > #include "cmockery.h" + > + > #include "postgres.h" + > + > void test_foo_bar(void** state) + > { + > assert_int_equal(0, 1); /* Do not do this. Provide a real test */ + > } + > + > int main(int argc, char* argv[]) + > { + > cmockery_parse_arguments(argc, argv); + > + > const UnitTest tests[] = { + > unit_test(test_foo_bar) + > }; + > return run_tests(tests); + > } + + +3. Insert new test case functions and register them in the main function. A + test function usually consists of three steps: + + - Describe the interaction of the called functions from the SUT with the + environment. This is only via expect_- and will_-functions from the + cmockery library. Will_ functions are used to define which mocked + functions are expected to be called by the test code. While the ordering + will_-function calls for different functions names don't need to be + strictly ordered, it is recommended to keep a strict ordering here. + Will-function calls also define the return values, assignments to + out-going parameters and side effects. This way we are able to define the + exact state a tested function can observe. + + In addition to the will_-functions, the expect_-functions are used to + describe our expectations about the values of parameters in the mocked + function calls. Details and a full list of the functions are showed later + in this document. + + - Call a function or a series of functions from the System Under Test. This + function or functions are the unit testing with a specific test case. + + - The return values and the state after each test function call, can be + validated by assert_ calls. A list of all available assert_ calls is + presented later in this document. + +== CMockery Usage == + +A cmockery test executable usually starts similar to this example from +heapam_test.c: + +int main(int argc, char* argv[]) { + cmockery_parse_arguments(argc, argv); + + const UnitTest tests[] = { + unit_test(test_heap_xlog_newpage) + }; + return run_tests(tests); +} + +The test framework accepts command line arguments: + +- --cmockery_abort_at_missing_check + In certain situations, is helpful to call the test executable with + --cmockery_abort_at_missing_check. When this option is activated or if the + cmockery_abort_at_missing_check() function is called, cmockery aborts instead + of failing a test when a check is missing. + + If used with a debugger attached or when generating core files, this helps to + identify where in the SUT code unexpected function calls have been made. + However, usually checked in code should not contain this + abort_at_missing_check call since otherwise all following tests in the test + executable are not executed at all. + +- --cmockery_generate_suppression + In certain situations, it is helpful to call the test executable with + --cmockery_generate_suppression. When this option is activated or if the + cmockery_enable_generate_suppression() function is called, cmockery outputs + example expect_ and will_ lines that are currently missing in the test + executable. + + While a test is pretty useless if it solely consists of generated expect_ + and will_ calls, it is helpful to setup the test environment. This is + especially true, if the test only deals with a certain line in a very long + function. + +- --run_disabled_tests + Certain test cases can be disabled with the disable_unit_test() function. + If cmockery is called with --run_disabled_tests, these tests are executed + even when they are disabled. + +A test function like test_heap_xlog_newpage in the example has the +signature "void test_heap_xlog_newpage(void** state)". The parameter state is +used by cmockery internally and should not be used or modified by the test +developer. + +The following functions are provided by cmockery to describe the interaction of +a SUT with its environment: + +=== Assertions === +- assert_true(c): Assert that the given expression is true. + If the expression is not true, the test fails. + +- assert_false(c): Asserts that the given expression is false. + If the expression is true, the test fails. + +- assert_int_equal(a, b): Asserts that two integral values are equal. + +- assert_int_not_equal(a, b): Asserts that two integral values are not equal. + +- assert_string_equal(a, b): Asserts that the contents of two strings are equal. + +- assert_string_not_equal(a, b): Asserts that the contents of two strings are + different. + +- assert_memory_equal(a, b, size): Asserts that two memory areas of a given + size have the same contents. + +- assert_memory_not_equal(a, b, size): Asserts that two memory areas of a given + size have different contents. + +- assert_in_range(value, min, max): Asserts that the value of an expression lies + in a given range. + +- assert_not_in_range(value, min, max): Similar to assert_in_range, but negates. + +- assert_in_set(value, values, number_of_values): Asserts that a value is in a + set of values. In contrast to except_in_set, values can be a pointer to an + array here. The parameter number_of_values determines the length of the array. + +- assert_not_in_set(value, values, number_of_values): Similar to assert_in_set, + but negates. + +=== Function call expectations === + +- will_return(function_name, value): Adds an expectation that a function with + the given name will be called once. If the function is called, the value + provided by will_return is returned to the SUT. + +- will_be_called(function_name): Adds an expectation that a function + with the given name will be called once. This function should be used for + functions that do not return values. + +- will_return_with_sideeffect(function_name, value, sideeffect_function, + sideeffect_data): + This function is similar to will_return, but also executes a callback + function. The callback can be used to perform actions on global variables. + +- will_be_called_with_sideeffect(function_name, sideeffect_function, + sideeffect_data): + This function is similar to will_be_called, but also executes a callback + function. The callback can be used to perform actions on global variables. + +=== Basic function parameter expectations === + +- expect_value(function_name, parameter, value): Adds an expectations that, + when a function is called, a parameter has a given value. If the function is + called, and the parameter has a different value the test fails. + +- expect_value_count(function_name, parameter, value, count): Similar to + expect_value, but expect that the function is consecutively called count + number of times with the parameter having the given value. If count is -1, + the function establishes that for all later calls of the function, the + parameter has to have the given value. Similar functions having a _count + suffix exist for all expect_ functions. + We will omit them for the other functions. + +- expect_not_value(function_name, parameter, value): Adds an expectation that a + parameter has not a given value. + +- expect_string(function_name, parameter, string): Adds an expectation that a + string parameter has a value equal to the given string. + +- expect_not_string(function_name, parameter, string): Adds an expectation that + a string parameter has a value not equal to the given string. + +- expect_any(function_name, parameter): Declares that we have no expectation on + a given parameter during a specific function call. This expectation never + fails. + +=== Advanced parameter expectations === + +- expect_memory(function_name, parameter, memory, size): Adds an expectation + that the memory a pointer parameter points is equal to the memory parameter + for the next size bytes. The data behind the memory parameter is copied and + can be safely modified or freed with out changing the expectation. + +- expect_not_memory(function_name, parameter, memory, size): + Similar to expect_memory, but negated. + +- expect_check(function_name, parameter, check_function, check_data): + Adds an expectation that when a function is called, a parameter fulfills a + certain property. + + The check_function has the signature int(const LongestIntegralValue value, + const LongtestIntegralValue check_data). + If the function returns 1 the value fulfills the property. 0 indicates an + error. The value is the value of the parameter during the function call + casted to the type LongestIntegralValue. Similarly, check_data is the data + from the check_data parameter of the expect_check call. + Usually this function is not used directly. + All other expect_ calls are implemented via expect_check. However, it can be + helpful for certain custom expectations. + +- expect_in_range(function, parameter, min, max): + Adds an expectation that a parameter value lies in a range. + +- expect_not_in_range(function, parameter, min, max): + Similar to expect_in_range, but negated. The parameter value should not be in + the given range. + +- expect_in_set(function, parameter, value_array): + Adds an expectation that a parameter value is in the set of values specified + by the value array. Note that the value array needs to be an actual array. + A pointer to values is not working. + +- expect_not_in_set(function, parameter, value_array): + Similar to expect_in_set, but negates. The parameter value should not be in + the set. + +- will_assign_value(function, parameter, value): + When the function is called, the given value will be assigned to the + dereferenced parameter. This function is used to assign + specific parameters to out-going parameters. + +- will_assign_string(function, parameter, string): + When the function is called, the given string will be assigned to the + out-going (aka non-const) string parameter. + +- will_assign_memory(function, parameter, memory, size): + When the function is called, the memory block is copied to the memory + the out-going (aka non-const) pointer parameter points to. + +=== Other cmockery features + +- If disable_unit_test() is called after the start of a test case function, the + execution of the test is skipped. While it is generally discouraged to skip a + test case because the test keeps failing, it is handy in certain situations. + +== Basic Tips == +- A unit test should be automated. It should not contain manual input. + If a test was successful or failed needs to be determined by assert_ and + expect_ calls and not be the "correct" output on screen. + +== Modification on cmockery == + +The underlying unit testing/mocking library cmockery is open sourced under +the Apache 2.0 license. To better suit our requirements, we have made the +following modifications + +- Add will_be_called for void functions +- Add will_assign_/optional_assignment to support out-going parameters +- Adds the option to abort on an missing expectation +- Adds the option to generate expect_/will_ statements on missing expectations +- Adds a better and colored console output +- Add the parsing of command line parameters + +== Further information == + +- cmockery Project Wiki: + http://code.google.com/p/cmockery/wiki/Cmockery_Unit_Testing_Framework + +- Wikipedia: + http://en.wikipedia.org/wiki/Unit_testing diff --git a/external-table/test/unit/cmockery/Makefile b/external-table/test/unit/cmockery/Makefile new file mode 100644 index 0000000000..a3614708e3 --- /dev/null +++ b/external-table/test/unit/cmockery/Makefile @@ -0,0 +1 @@ +CMOCKERY_OBJS=${CMOCKERY_DIR}/cmockery.o \ No newline at end of file diff --git a/external-table/test/unit/cmockery/README.txt b/external-table/test/unit/cmockery/README.txt new file mode 100644 index 0000000000..c95692a58e --- /dev/null +++ b/external-table/test/unit/cmockery/README.txt @@ -0,0 +1,3 @@ +Modified version of the cmockery unit testing/mock framework + +Apache License 2.0 \ No newline at end of file diff --git a/external-table/test/unit/cmockery/cmockery.c b/external-table/test/unit/cmockery/cmockery.c new file mode 100644 index 0000000000..1ce08a3e5a --- /dev/null +++ b/external-table/test/unit/cmockery/cmockery.c @@ -0,0 +1,2031 @@ +/* + * Copyright 2008 Google Inc. + * + * Licensed under the Apache License, Version 2.0 (the "License"); + * you may not use this file except in compliance with the License. + * You may obtain a copy of the License at + * + * http://www.apache.org/licenses/LICENSE-2.0 + * + * Unless required by applicable law or agreed to in writing, software + * distributed under the License is distributed on an "AS IS" BASIS, + * WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or implied. + * See the License for the specific language governing permissions and + * limitations under the License. + */ +#ifdef HAVE_CONFIG_H +#include "config.h" +#endif +#ifdef HAVE_MALLOC_H +#include +#endif +#include +#ifndef _WIN32 +#include +#include +#endif // !_WIN32 +#include +#include +#include +#include +#include +#ifdef _WIN32 +#include +#endif // _WIN32 +#include + +#ifdef _WIN32 +#define vsnprintf _vsnprintf +#endif // _WIN32 + +/* Backwards compatibility with headers shipped with Visual Studio 2005 and + * earlier. */ +#ifdef _WIN32 +WINBASEAPI BOOL WINAPI IsDebuggerPresent(VOID); +#endif // _WIN32 + +// Size of guard bytes around dynamically allocated blocks. +#define MALLOC_GUARD_SIZE 16 +// Pattern used to initialize guard blocks. +#define MALLOC_GUARD_PATTERN 0xEF +// Pattern used to initialize memory allocated with test_malloc(). +#define MALLOC_ALLOC_PATTERN 0xBA +#define MALLOC_FREE_PATTERN 0xCD +// Alignment of allocated blocks.
