### A Simple Test

The ITest subclass ISimpleTest is a very simple test of ITarget. ISimpleTest overrides ITest::test() to check if ITarget::maxLength() returns a correct value. To perform this test, it instantiates a target class and calls maxLength(). If the result is correct, it sets Success to true; otherwise, it sets Success to false.

    // itarget.hpp
    class ITarget{
    public:
    		 ITarget(int maxlength) { fMaxLength = maxlength;}
        virtual         ~ITarget() {}
        int   maxLength() { return fMaxlength; }
    private:
        int fMaxlength;
    };

    // itarget .cpp
    // test class
    #include <runtest.hpp>
    #include <itest.hpp>
    #include "itarget.hpp"

    class ISimpleTest : public ITest {
    public:
                        ISimpleTest();
        virtual         ~ISimpleTest();

    protected:
        virtual void    test();

    private:
    };

    ISimpleTest::ISimpleTest() { }

    ISimpleTest::~ISimpleTest() { }

    void ISimpleTest::test()
    {
    	int correctLength = 100;

    	ITarget target(correctLength);
    	if (target.maxLength() != correctLength)
    	{
    		outputTextStream() << "length doesn't match";
    		setsuccess(false);
    	}
    	else
                    setsuccess(true);
    }
