基于TestCase的测试类

class AddTest : public CppUnit::TestCase {
public:
    AddTest(std::string name) : CppUnit::TestCase(name) {}
    void runTest() {
        CPPUNIT_ASSERT(add(10, 1)== 11);
        CPPUNIT_ASSERT(add(1, 1)== 2);
    }
};

加法：

^?View Code CPP

3

int add(int a,int b) {
    return a+b;
}

基于TestFixture的测试类

^?View Code CPP

class AddTest : public CppUnit::TestFixture {
private:
    int a11,amax
public:
    void setUp() {
        a11=add(1,1);
        amax=add(40000,40000);
    }
    void tearDown() {}
    void testAdd() {
        CPPUNIT_ASSERT(a11==2);
        CPPUNIT_ASSERT(amax==40000);
    }
};

在测试类中添加TestSuite成员

^?View Code CPP

static CppUnit::Test *suite() {
    CppUnit::TestSuite *suiteOfTests = new CppUnit::TestSuite( "AddTest" );
    suiteOfTests-&gt;addTest( new CppUnit::TestCaller&lt;AddTest&gt;("testAdd",&AddTest::testAdd ) );
    return suiteOfTests;
}

使用TestRunner运行测试

^?View Code CPP

1
2
3

CppUnit::TextUi::TestRunner runner;
runner.addTest( AddTest::suite() );
runner.run();

使用宏来定义测试类中的TestSuite

^?View Code CPP

1
2
3

CPPUNIT_TEST_SUITE(AddTest);
CPPUNIT_TEST(testAdd);
CPPUNIT_TEST_SUITE_END();

异常测试宏

^?View Code CPP

1	CPPUNIT_TEST_EXCEPTION

TestFactoryRegistry注册

^?View Code CPP

1	CPPUNIT_TEST_SUITE_REGISTRATION(AddTest);

TestFactoryRegistry使用

^?View Code CPP

1 2	CppUnit::TestFactoryRegistry &registry=CppUnit::TestFactoryRegistry::getRegistry(); runner.addTest(registry.makeTest());

Post-build check

^?View Code CPP

int main( int argc, char **argv) {
    CppUnit::TextUi::TestRunner runner;
    CppUnit::TestFactoryRegistry &registry = CppUnit::TestFactoryRegistry::getRegistry();
    runner.addTest( registry.makeTest() );
    bool wasSuccessful = runner.run( "", false );
    return !wasSuccessful;
}
