Hello Raffi,

...

my test program uses boost.test datasets. I've wrote a filesystem loader for the input and expected data. Now I run into the problem, that boost::unit_test::framework::master_test_suite().{argc, argv} is only setup inside the tests self. My loader isn't a test case ... I can check it by using a simple mock, like

struct app_mock { app_mock();

int const argc; char** const argv; };

app_mock::app_mock() : argc(boost::unit_test::framework::master_test_suite().argc) , argv(boost::unit_test::framework::master_test_suite().argv) { }

BOOST_AUTO_TEST_CASE( app_mocker ) { app_mock app; std::cout << "Count = " << app.argc << '\n'; for(int i = 0; i != app.argc; i++) std::cout << "Arg = " << app.argv[i] << '\n'; }

$ my_test -- my_args

Count = 2

path/to/exe

my_args

these works, but as mentioned:

dataset_loader::dataset_loader(fs::path const& path) { app_mock app;

std::cout << "ARGC = " << boost::unit_test::framework::master_test_suite().argc << '\n'; read_files(path); }

is always zero.

How can I read the argc/argv values?

Thanks,

Olaf

The datasets are creating static objects on file scope, that generate the definition of the unit tests.

I believe you can achieve what you want here by loading the data from a suite fixture associated to the dataset test case. Otherwise, bring the topic to a trac issue.

As far I can see, it can't work, since how can I pass arguments to the constructor? My use case is ::x3_test::dataset_loader foo_dataset{ "test/foo" }; BOOST_DATA_TEST_CASE(foo, foo_dataset.input() ^ foo_dataset.expect() ^ foo_dataset.test_file_name(), input, expected, file) { ... } where a lot of datasets are required with different paths to the test files. Otherwise a simple: struct foo_dataset : public ::dataset_loader { foo_dataset() : dataset_loader { "test/foo" } { } }; BOOST_DATA_TEST_CASE_F( foo_dataset, foo_test_case, foo_dataset.input() ^ foo_dataset.expect() ^ foo_dataset.test_file_name(), input, expected, file) { ... } doesn't compile: error: 'foo_test_case' has not been declared. Thanks, Olaf
