禁用从数据集定义的特定测试实例

Question

假设我有以下测试代码：

struct MyData
{
    MyData( int in_, double out_ )
    : m_in{ in_ }
    , m_out{ out_ }
    {}

    int    m_in;
    double m_out;
};

std::ostream& operator<<( std::ostream& os_, MyData data_ )
{
    os_ << data_.m_in << " " << data_.m_out << std::endl;
    return os_;
}

std::vector< MyData > DataSetGet()
{
    return
        {
            { 1, 1.0 },
            { 2, 2.0 }, // I would like to disable this...
            { 3, 3.0 },
        };
}

BOOST_DATA_TEST_CASE( CastIntToDouble, DataSetGet() )
{
    BOOST_TEST( static_cast< double >( sample.m_in ) == sample.m_out );
}

我想禁用第二个测试实例。我可以像这样注释掉第二种情况：

std::vector< MyData > DataSetGet()
{
    return
        {
            { 1, 1.0 },
            //{ 2, 2.0 }, // I would like to disable this...
            { 3, 3.0 },
        };
}

但是这个案例将不再被编译，这不是我要找的。在我的真实场景中，测试用例更复杂，我希望它们被编译，但不是运行.

我搜索了有关此主题的 boost 文档，发现了 disable decorator，它看起来正是我需要的。但是，我没有找到在数据测试用例中使用它的方法。这可能吗？

你可以supply a command line argument，比如：

./sotest -l all -t "!*/*_1"

BOOST_DATA_TEST_CASE(CastIntToDouble, DataSetGet())

运行和

g++ -std=c++20 -O2 -Wall -pedantic -pthread main.cpp -lboost_unit_test_framework
./a.out -l all -t "!*/*_1" --no_color_output
