gtest 学习之五 测试用例中定义类

上一个例子中被测试的类是作为测试类的一个成员变量，在本例中没有测试类，被测试类只能在一个测试用例中定义使用

头文件sample4.h

#ifndef GTEST_SAMPLES_SAMPLE4_H_
#define GTEST_SAMPLES_SAMPLE4_H_

// A simple monotonic counter.
class Counter {
private:
    int counter_;

public:
    // Creates a counter that starts at 0.
    Counter() : counter_(0) {}

    // Returns the current counter value, and increments it.
    int Increment();

    // Prints the current counter value to STDOUT.
    void Print() const;
};

#endif  // GTEST_SAMPLES_SAMPLE4_H_

 

main.cpp:

#include "gtest/gtest.h"
#include "sample4.h"

TEST(Counter, Increment) {
    Counter c;//在测试用例中定义变量

    // EXPECT_EQ() evaluates its arguments exactly once, so they
    // can have side effects.

    EXPECT_EQ(0, c.Increment());
    EXPECT_EQ(1, c.Increment());
    EXPECT_EQ(2, c.Increment());
}

int main(int argc, char *argv[])
{
    testing::InitGoogleTest(&argc, argv);
    return RUN_ALL_TESTS();
}

运行结果：
