Re: [Boost-users] [UTF] Accessing global fixture members within tests

Hi

I am using the Unit Test Framework to test my use of boost.python. I am using a global fixture to initialize the python intepreter a single time (rather than before each test).

My problem is I would like to use the Python initialising class in my tests, and I can't figure out how to do this. I don't want to use normal fixtures since each test would call initialize the interpreter, causing problems.

Here is what I want to do:

////////////////////////////////////////////////////// #include #include

#include "..//pythonManager//pythonManager.h"

using namespace boost;

// First make a global fixture which sets up python interpreter struct PythonManagerFixture { PythonManagerFixture() { pm.Init(); } PythonManager pm; };

// Set up suite BOOST_AUTO_TEST_SUITE(TestPythonManager)

// Only init python interpreter once BOOST_GLOBAL_FIXTURE(PythonManagerFixture);

BOOST_AUTO_TEST_CASE(TestInit) { // Get python globals dict python::dict globalDict = python::extractpython::dict(pm.m_pyGlobals); // COMPILE ERROR 'pm' : undeclared identifier // Has logging module been imported? BOOST_REQUIRE(globalDict.has_key("logging")); }

BOOST_FIXTURE_TEST_CASE(TestLogCallback, PythonManagerFixture) // RUNTIME ERROR pm.Init called a second time - bad { function f = pm.GetLogFunction(); // pm is in scope though.... BOOST_REQUIRE(f); }

// End the suite BOOST_AUTO_TEST_SUITE_END() ///////////////////////////////////////////////////////////////////

I need a way to supply the PythonManager instance, pm, to the test cases.

Thanks for any advice

Ah, I needed the subtle distinction of a BOOST_FIXTURE_TEST_SUITE, not a BOOST_FIXTURE_TEST_CASE

Alas, I am mistaken. BOOST_FIXTURE_TEST_SUITE is simply a convenience macro, removing the need to add a fixture to each test case. What I need is a way to perform the fixture setup ONCE, yet allow test cases access to the public members
