简单的介绍

TEST(测试套，测试名) 测试套随意起名即可
TEST_p(测试套，)

说明

本地自己配置gtest很麻烦...直接用visual studio 2017+版本，直接有gtest
教程

ubuntu上配置gtest更简单，教材

hello world

test.cpp

#include "pch.h"

TEST(TestCaseName, TestName) {
  EXPECT_EQ(1, 1);
  EXPECT_EQ(3, add(1, 2));
  EXPECT_EQ(4, add(2, 2));
  EXPECT_TRUE(true);
}

pch.h

//
// pch.h
//

#pragma once

#include "gtest/gtest.h"
int add(int a, int b);

pch.cpp

#include "pch.h"
int add(int a, int b)
{
	return a + b;
}
