Question

我创建了一个类和一个验证器，所以我想使用断言为验证器做一些测试。这就是我所说的：

类医学

class Medicine{
private:
    int ID;
    string name;
public:
    Medicine(){
        this->ID=0;
        this->name="";
    }
    Medicine(int ID, string name, float concentration, int quantity){
        this->ID=ID;
        this->name=name;
    }
    ~Medicine(){};

    //inline get methods

    int getID(){
        return ID;
    }

    string& getName(){
        return name;
    }

    //inline set methods

    void setID(int newID){
        this->ID = newID;
    }

    void setName(string newName){
        this->name = newName;
    }
};

exceptions.h

#include <string>
using namespace std;

#include <string>
using namespace std;

class MyException
{
public:
    MyException(string msg):message(msg){}
    const string& getMessage() const {return message;}
private:
    string message;
};

class ValidatorException: public MyException
{
public:
    ValidatorException(string msg): MyException(msg){}
};

class RepositoryException: public MyException
{
public:
    RepositoryException(string msg): MyException(msg){}
};

药物治疗师

#include "exceptions.h"
#include "medicine.h"

class MedicineValidator{
public:
    void validate(Medicine& m) throw (ValidatorException);
};

#include "medicineValidator.h"

void MedicineValidator::validate(Medicine& m) throw (ValidatorException){
    string message="";
    if(m.getID()<1){
        message+="The ID should be positive and >0!";
    }
    if(m.getName()==""){
        message+="The name field is empty, and it shouldn't!";
    }
    if(m.getConcentration()<1){
        message+="The concentration should be positive(>0)!";
    }
    if(m.getQuantity()<1){
        message+="The quantity should be positive(>0)!";
    }
}

测试验证器的算法：

void testValidator(){
    Medicine* m = new Medicine(1,"para",30,40);
    MedicineValidator* medValidator = new MedicineValidator();
    medValidator->validate(*m);

    m->setID(-2); //the ID should not be < 1 so it should catch the exception but the test fails
    try{
        medValidator->validate(*m);
        assert(false);
    }
    catch(ValidatorException& ex){
        assert(true);
    }
    delete m;
}

我做错了什么？我只是看不出错误......也许你可以。 :)当我运行程序时，这就是我得到的：“断言失败：false，文件.. \ src / utils /../ domain / testMedicine.h，第32行

此应用程序已请求Runtime以不寻常的方式终止它。请联系应用程序的支持团队获取更多信息。“

您不会在验证方法中抛出异常消息

和assert（false）中止程序执行

验证失败的断言
