Examples

The demo program shipped with the QxCppUnit library can be used as the starting point for writing a GUI test runner for CppUnit. It has some CppUnit test fixtures with simple test cases which succeed or fail and uses a TestRunner instance in the main program to launch the GUI.

A CppUnit Test Example

This is one of the test fixtures of the demo program. Of course this is a very simple test and only used for demonstration purposes. It isn't intended to show how to write CppUnit tests.

// This class implements a set of CppUnit example test cases which
// succeed or fail. It isn't intended to show how to write CppUnit tests.

#include <cppunit/TestFixture.h>
#include <cppunit/extensions/HelperMacros.h>

class TestExamples2;

CPPUNIT_TEST_SUITE_REGISTRATION(TestExamples2);

class TestExamples2 : public CPPUNIT_NS::TestFixture
{
    CPPUNIT_TEST_SUITE(TestExamples2);

    CPPUNIT_TEST(testFail);
    CPPUNIT_TEST(testAssertAssertionPass);
    CPPUNIT_TEST(testAssertAssertionFail);
    CPPUNIT_TEST(testUnhandledError);

    CPPUNIT_TEST_SUITE_END();

    void testFail()
    {
        CPPUNIT_FAIL("Intentionally failed");
    }

    void testAssertAssertionPass()
    {
        CPPUNIT_ASSERT_ASSERTION_PASS(CPPUNIT_ASSERT(1 == 1));
    }

    void testAssertAssertionFail()
    {
        CPPUNIT_ASSERT_ASSERTION_FAIL(CPPUNIT_ASSERT(1 == 2));
    }

    void testUnhandledError()
    {
        throw "Unhandled error";
    }
};

The Demo Main Program

The main program is straightforward:

#include <QApplication>
#include <qxcppunit/testrunner.h>
#include <cppunit/extensions/TestFactoryRegistry.h>

int main(int argc, char *argv[])
{
    QApplication app(argc, argv);

    QxCppUnit::TestRunner runner;

    runner.addTest(CPPUNIT_NS::TestFactoryRegistry::getRegistry().makeTest());
    runner.run();

    return 0;
}
