Boost C++ Libraries

Declares and registers a data-driven test case, using a particular dataset.

Several forms of the macro are available.

BOOST_DATA_TEST_CASE(test_case_name, dataset)
{
  BOOST_TEST(sample != 0);
}

should be used for datasets with arity 1. In the body of the test case, the samples of the dataset are taken by the variable sample.

BOOST_DATA_TEST_CASE(test_case_name, dataset, var1)
{
  BOOST_TEST(var1 != 0);
}

same as the first form, but the samples are taken by the variable var1 instead of the variable sample

BOOST_DATA_TEST_CASE(test_case_name, dataset, var1, var2..., varN)
{
  BOOST_TEST(var1 != 0);
  //...
  BOOST_TEST(varN != 0);
}

same as the second form, but for dataset of arity N.

For compilers lacking the variadic template support, the maximal arity (the maximal value of N) is controlled by the macro BOOST_TEST_DATASET_MAX_ARITY which is set to 10 by default. If you need a greater value, define BOOST_TEST_DATASET_MAX_ARITY to the desired value before including the Unit Test Framework headers.
