Error setting up world results in successful exit

[rkennedy]

If a fixture has a setUpWorld method defined, and that method returns false, then the test runner will run no tests, and the program will terminate with exit status 0. The documentation doesn't actually say what happens when setUpWorld returns false, but I wouldn't expect a successful exit status.

Consider the following code:

#include <iostream>
#include <cxxtest/TestSuite.h>
#include <cxxtest/GlobalFixture.h>

class Fixture1: public CxxTest::GlobalFixture
{
public:
    bool setUpWorld() {
        std::clog << "Fixture1::setUpWorld about to return false" << std::endl;
        return false;
    }
};
static Fixture1 fixture1;

class Suite: public CxxTest::TestSuite
{
public:
    void testShouldFail() {
        TS_FAIL("This should never run.");
    }
};

I compiled and ran it as follows:

cxxtestgen --abort-on-fail --error-printer --have-std --have-eh test.h -o test.cpp
clang++ -Wall test.cpp
./a.out

Output is this:

Running cxxtest tests (1 test)Fixture1::setUpWorld about to return false

In <no suite>::<no test>:
/usr/local/include/cxxtest/RealDescriptions.cpp:5: Warning: Error setting up world
OK!

Furthermore, echo $? prints 0. The exit status and the OK! at the end of the output mean that any script running this test program will consider it successful even though it failed on setup.
