Is it possible to mix up the BOOST_AUTO_TEST_CASE
and BOOST_AUTO_TEST_CASE_TEMPLATE
macros with the BOOST_PARAM_TEST_CASE
in any way? I\'m
Since Boost 1.59 internal details of realization was changed and Omnifarious's solution doesn't compile.
Reason ot that is changing signature of boost::unit_test::make_test_case
function: now it take 2 additional args: __FILE__, __LINE__
Fixed solution:
#if BOOST_VERSION > 105800
#define MY_BOOST_TEST_ADD_ARGS __FILE__, __LINE__,
#define MY_BOOST_TEST_DEFAULT_DEC_COLLECTOR ,boost::unit_test::decorator::collector::instance()
#else
#define MY_BOOST_TEST_ADD_ARGS
#define MY_BOOST_TEST_DEFAULT_DEC_COLLECTOR
#endif
#define BOOST_FIXTURE_PARAM_TEST_CASE( test_name, F, mbegin, mend ) \
struct test_name : public F { \
typedef ::std::remove_const< ::std::remove_reference< decltype(*(mbegin)) >::type>::type param_t; \
void test_method(const param_t &); \
}; \
\
void BOOST_AUTO_TC_INVOKER( test_name )(const test_name::param_t ¶m) \
{ \
test_name t; \
t.test_method(param); \
} \
\
BOOST_AUTO_TU_REGISTRAR( test_name )( \
boost::unit_test::make_test_case( \
&BOOST_AUTO_TC_INVOKER( test_name ), #test_name, \
MY_BOOST_TEST_ADD_ARGS \
(mbegin), (mend)) \
MY_BOOST_TEST_DEFAULT_DEC_COLLECTOR); \
\
void test_name::test_method(const param_t ¶m) \
#define BOOST_AUTO_PARAM_TEST_CASE( test_name, mbegin, mend ) \
BOOST_FIXTURE_PARAM_TEST_CASE( test_name, \
BOOST_AUTO_TEST_CASE_FIXTURE, \
mbegin, mend)
You can easily mix manual and automated test unit registration. Implement your own init function (like in example 20 on this page) and inside init function you can perform registration for parameterized test cases. Boost.Test will merge them both into single test tree.
I wrote my own support for this since there really didn't seem to be any good support. This requires the C++11 decltype
feature and the ::std::remove_const
and ::std::remove_reference
library methods to work.
The macro definitions are a modified versions of the BOOST_FIXTURE_TEST_CASE
and BOOST_AUTO_TEST_CASE
macros.
You use this by declaring your function thus:
BOOST_AUTO_PARAM_TEST_CASE(name, begin, end)
{
BOOST_CHECK_LT(param, 5); // The function will have an argument named 'param'.
}
Here is the header that defines the BOOST_AUTO_PARAM_TEST_CASE
macro:
#include <boost/test/unit_test_suite.hpp>
#include <boost/test/parameterized_test.hpp>
#include <type_traits>
#define BOOST_FIXTURE_PARAM_TEST_CASE( test_name, F, mbegin, mend ) \
struct test_name : public F { \
typedef ::std::remove_const< ::std::remove_reference< decltype(*(mbegin)) >::type>::type param_t; \
void test_method(const param_t &); \
}; \
\
void BOOST_AUTO_TC_INVOKER( test_name )(const test_name::param_t ¶m) \
{ \
test_name t; \
t.test_method(param); \
} \
\
BOOST_AUTO_TU_REGISTRAR( test_name )( \
boost::unit_test::make_test_case( \
&BOOST_AUTO_TC_INVOKER( test_name ), #test_name, \
(mbegin), (mend))); \
\
void test_name::test_method(const param_t ¶m) \
// *******
#define BOOST_AUTO_PARAM_TEST_CASE( test_name, mbegin, mend ) \
BOOST_FIXTURE_PARAM_TEST_CASE( test_name, \
BOOST_AUTO_TEST_CASE_FIXTURE, \
mbegin, mend)
The solution provided by @Omnifarious works works, but requires a C++11 compiler.
Adapting that solution for a C++03 compiler:
#include <boost/test/unit_test_suite.hpp>
#include <boost/test/parameterized_test.hpp>
#define BOOST_FIXTURE_PARAM_TEST_CASE( test_name, F, P, mbegin, mend ) \
struct test_name : public F \
{ \
typedef P param_t; \
void test_method(const param_t &); \
}; \
\
void BOOST_AUTO_TC_INVOKER( test_name )(const test_name::param_t ¶m) \
{ \
test_name t; \
t.test_method(param); \
} \
\
BOOST_AUTO_TU_REGISTRAR( test_name )( \
boost::unit_test::make_test_case( \
&BOOST_AUTO_TC_INVOKER( test_name ), #test_name, \
(mbegin), (mend))); \
\
void test_name::test_method(const param_t ¶m) \
// *******
#define BOOST_AUTO_PARAM_TEST_CASE( test_name, param_type, mbegin, mend ) \
BOOST_FIXTURE_PARAM_TEST_CASE( test_name, \
BOOST_AUTO_TEST_CASE_FIXTURE, \
param_type, \
mbegin, mend)
This solution is slightly different is usage. Since there is no declspec
in C++03, the type of the parameter object cannot be automatically deduced. We must pass it in as a parameter to BOOST_AUTO_PARAM_TEST_CASE
:
class FooTestParam
{
public:
std::string mS;
FooTestParam (int n)
{
std::stringstream ss;
ss << n;
mS = ss.str();
}
};
FooTestParam fooParams [] =
{
FooTestParam (42),
FooTestParam (314)
};
BOOST_AUTO_PARAM_TEST_CASE (TestFoo, FooTestParam, fooParams, fooParams + 2)
{
const std::string testVal = param.mS;
}
BOOST_AUTO_TEST_CASE (TestAddressField)
{
const uint32_t raw = 0x0100007f; // 127.0.0.1
const uint8_t expected[4] = {127, 0, 0, 1};
const Mdi::AddressField& field = *reinterpret_cast <const Mdi::AddressField*> (&raw);
for (size_t i = 0; i < 4; ++i)
BOOST_CHECK_EQUAL (field[i], expected[i]);
}
Starting with Boost version 1.59, this is being handled by data-driven test cases:
#define BOOST_TEST_MODULE MainTest
#include <boost/test/included/unit_test.hpp>
#include <boost/test/data/test_case.hpp>
#include <boost/array.hpp>
static const boost::array< int, 4 > DATA{ 1, 3, 4, 5 };
BOOST_DATA_TEST_CASE( Foo, DATA )
{
BOOST_TEST( sample % 2 );
}
This functionality requires C++11 support from compiler and library, and does not work inside a BOOST_AUTO_TEST_SUITE
.
If you have to support both old and new versions of Boost in your source, and / or pre-C++11 compilers, check out And-y's answer.
I took Omnifarious' header file and modified it such that the parameter is passed to the constructor of the test fixture rather than to the test method. This requires the test fixture's constructor declaration to take a single argument with the parameter's type. I found this to be super handy--much thanks for the initial question and answer!
