CppUnit类结构UML图

这个CppUnit包是POCO中的CppUnit的简化版本，但是开展测试C++的测试用例来说已经足够了。

2、代码示例

类foo，完成加法，等功能

class CFoo
{
public:
    int a(int a, int b)
    {
        return a + b;
    }
    char c()
    {
        return 'c';
    }
    void t()
    {
        throw std::exception("foo exception.");
    }
};

继承自TestCase的单元测试类

#include "CppUnit/TestCaller.h"
#include "CppUnit/TestSuite.h"
class CFooTest: public CppUnit::TestCase
{
public:
    CFooTest(const std::string& name):CppUnit::TestCase(name)
    { }

    ~CFooTest()
    { }

    void testa()
    {
        CFoo foo;
        int a = foo.a(1,2);
        assert(3 == a);
        char *p = NULL;
        assertEqual(1.3,1.3);
    }

    void testc()
    {
        CFoo foo;
        assert(foo.c() == 'c');
    }

    void testt()
    {
        CFoo foo;
        try
        {
            foo.t();
            fail("will not run.");
        }
        catch (std::exception& )
        {

        }
    }

    void testThrow()
    {
        CFoo foo;
        foo.t();
    }

    void setUp()
    { }

    void tearDown()
    { }

    static CppUnit::Test* suite()
    {
        CppUnit::TestSuite* pSuite = new CppUnit::TestSuite("CFooTestSuite");
        CppUnit_addTest(pSuite,CFooTest,testa);
        CppUnit_addTest(pSuite,CFooTest,testc);
        CppUnit_addTest(pSuite,CFooTest,testt);
        CppUnit_addTest(pSuite,CFooTest,testThrow);

        return pSuite;
    }
};

main函数

#include "CppUnit/TestRunner.h"
#include "CppUnit/TextTestResult.h"
#include "CppUnit/TestSuite.h"

int main()
{
    /* 终极suite，将其他suite都包到里面来 */
    CppUnit::TestSuite* pSuite = new CppUnit::TestSuite("main");
    pSuite->addTest(CFooTest::suite());
    // pSuite->addTest Other suites.

    // TestRunner用于运行测试用例
    CppUnit::TestRunner runnre;
    runnre.addTest("main",pSuite);
    std::vector<std::string> args;
    args.push_back("drive");
    args.push_back("-all");
    args.push_back("-print");

    runnre.run(args);

    return 0;
}
