我尝试编译以下代码:
#include <cppunit/extensions/HelperMacros.h>
#include "tested.h"
class TestTested : public CppUnit::TestFixture
{
CPPUNIT_TEST_SUITE(TestTested);
CPPUNIT_TEST(check_value);
CPPUNIT_TEST_SUITE_END();
public:
void check_value();
};
CPPUNIT_TEST_SUITE_REGISTRATION(TestTested);
void TestTested::check_value() {
tested t(3);
int expected_val = t.getValue(); // <----- Line 18.
CPPUNIT_ASSERT_EQUAL(7, expected_val);
}
结果我得到:
testing.cpp:18:32: Error: void-value is not ignored where it should be
编辑
为了使示例完整,我发布了tested.h
and的代码tested.cpp
:
tested.h
#include <iostream>
using namespace std;
class tested {
private:
int x;
public:
tested(int int_x);
void getValue();
};
tested.cpp
#include <iostream>
using namespace std;
tested::tested(int x_inp) {
x = x_inp;
}
int tested::getValue() {
return x;
}
