<syntaxhighlight lang="cpp">
#include <gtest/gtest.h>

// 被测函数
int Factorial(int n) {
    return n <= 1 ? 1 : n * Factorial(n - 1);
}

// 测试套件定义
TEST(FactorialTest, HandlesPositiveInput) {
    EXPECT_EQ(Factorial(1), 1);
    EXPECT_EQ(Factorial(2), 2);
    EXPECT_EQ(Factorial(3), 6);
    EXPECT_EQ(Factorial(10), 3628800);
}

TEST(FactorialTest, HandlesZeroInput) {
    ASSERT_EQ(Factorial(0), 1);
}

输出示例：
