I'va安裝了CppUnit庫上的Kubuntu我11.10,使用這個命令:錯誤與編譯源文件,它使用的CppUnit類
命令和apt-get安裝libcppunit-1.12-1 libcppunit-dev的libcppunit-doc的 須藤apt-get的這個我運行之前安裝libcppunit亞基-dev的libcppunit-subunit0
:apt-cache search cppunit
命令,其結果是:
libcppunit-1.12-1 - Unit Testing Library for C++
libcppunit-dev - Unit Testing Library for C++
libcppunit-doc - Unit Testing Library for C++
libcppunit-subunit-dev - SubunitTestProgressListener for CPPUnit - Development headers
libcppunit-subunit0 - SubunitTestProgressListener for CPPUnit - C++ shared library
libcunit1 - Unit Testing Library for C
libcunit1-dev - Unit Testing Library for C -- development files
libcunit1-doc - Unit Testing Library for C -- documentation
libcunit1-ncurses - Unit Testing Library for C (ncurses)
libcunit1-ncurses-dev - Unit Testing Library for C (ncurses) -- development files
libqxcppunit-dev - A Qt4-based GUI for running tests with CppUnit - development files
libqxcppunitd1 - A Qt4-based GUI for running tests with CppUnit
我已經有了一個學習單元測試一個簡單的源文件:
#include <iostream>
#include <cppunit/TestCase.h>
#include <cppunit/extensions/HelperMacros.h>
class MyDate
{
private:
struct Duration
{
int year;
int month;
int day;
Duration(int y, int m, int d) :
year(y), month(m), day(d)
{}
} mdata;
public:
MyDate() : mdata(2011, 11, 15)
{}
MyDate(int year, int month, int day) : mdata(year, month, day)
{}
int getYear() const
{ return mdata.year; }
int getMonth() const
{ return mdata.month; }
int getDay() const
{ return mdata.day; }
friend bool operator < (MyDate const& lhs, MyDate const& rhs)
{
if (lhs.mdata.year > rhs.mdata.year)
return false;
else if (lhs.mdata.year < rhs.mdata.year)
return true;
else if (lhs.mdata.year == rhs.mdata.year)
{
if (lhs.mdata.month > rhs.mdata.month)
return false;
else if (lhs.mdata.month < rhs.mdata.month)
return true;
else if (lhs.mdata.month == rhs.mdata.month)
{
if (lhs.mdata.day < rhs.mdata.day)
return true;
else
return false;
}
}
return false;
}
};
class MyDateTest : public CppUnit::TestCase
{
MyDate mybday;
MyDate today;
public:
MyDateTest() : mybday(1951, 10, 1) {}
void run()
{
testOps();
}
void testOps()
{
CPPUNIT_ASSERT(mybday < today);
}
};
int main()
{
MyDateTest test;
test.run();
return 0;
}
但是當我編譯我的cpp文件,使用G ++,我有以下錯誤:

什麼問題?
您可能需要鏈接到cppunit庫。 –
