学习使用Google Test

主要参考: 玩转Google开源C++单元测试框架Google Test系列(gtest)之一 - 初识gtest

配置好VS后, 编写第一个Demo.

   1:  // gTest.cpp : 定义控制台应用程序的入口点。

   2:  //

   3:   

   4:  #include "stdafx.h"

   5:   

   6:  int Foo(int a, int b)

   7:  {

   8:      if (a == 0 || b == 0)

   9:      {

  10:          throw "don't do that";

  11:      }

  12:      int c = a % b;

  13:      if (c == 0)

  14:          return b;

  15:      return Foo(b, c);

  16:  }

  17:   

  18:  int Add(int a, int b)

  19:  {

  20:      return a + b;

  21:  }

  22:   

  23:  #include <gtest/gtest.h>

  24:   

  25:  TEST(FooTest, HandleNoneZeroInput)

  26:  {

  27:      EXPECT_EQ(2, Foo(4, 10));

  28:      EXPECT_EQ(6, Foo(30, 18));

  29:      //ASSERT_EQ(3, Foo(3, 6));

  30:      //ASSERT_EQ(3, Foo(3, 7));

  31:      //EXPECT_EQ(3, Foo(5, 7));

  32:  }

  33:   

  34:  TEST(AddTest, HandleNoneZeroInput)

  35:  {

  36:      EXPECT_EQ(2, Add(1, 1));

  37:      //EXPECT_EQ(2, Add(1, 2));

  38:  }

  39:   

  40:  int _tmain(int argc, _TCHAR* argv[])

  41:  {

  42:      testing::InitGoogleTest(&argc, argv);

  43:      return RUN_ALL_TESTS();

  44:  }

  45:   

.csharpcode, .csharpcode pre
{
font-size: small;
color: black;
font-family: consolas, "Courier New", courier, monospace;
background-color: #ffffff;
/*white-space: pre;*/
}
.csharpcode pre { margin: 0em; }
.csharpcode .rem { color: #008000; }
.csharpcode .kwrd { color: #0000ff; }
.csharpcode .str { color: #006080; }
.csharpcode .op { color: #0000c0; }
.csharpcode .preproc { color: #cc6633; }
.csharpcode .asp { background-color: #ffff00; }
.csharpcode .html { color: #800000; }
.csharpcode .attr { color: #ff0000; }
.csharpcode .alt
{
background-color: #f4f4f4;
width: 100%;
margin: 0em;
}
.csharpcode .lnum { color: #606060; }

运行结果如下图所示:
