How to do it...

To write tests using the traditional style, with test cases and test functions, do this:

• Use the TEST_CASE macro to define a test case with a name (as a string), and optionally, a list of its associated tags:

        TEST_CASE("test construction", "[create]")        {          // define sections here        }

• Use the SECTION macro to define a test function inside a test case, with name as a string:

        TEST_CASE("test construction", "[create]")        {          SECTION("test constructor")          {            auto p = point3d{ 1,2,3 };            REQUIRE(p.x() == 1);            REQUIRE(p.y() == 2);            REQUIRE(p.z() == 4);          }        }

• Define nested sections if you want to reuse the setup and teardown code or organize your tests in a hierarchical structure:

        TEST_CASE("test operations", "[modify]")        { SECTION("test ...
