单元测试在产品开发中，是对我们代码运行结果核对的有力保障，可以有效减少产品开发测试出现的bug，也能随时记录接口调用示例，并随时对我们的测试目标进行检查。

GTEST测试框架是Goole发布的支持Windows/Linux/MacOS的单元测试框架。

1.TEST宏

TEST(test_case_name, test_name) -> 创建一个简单的测试案例

TEST_F(test_fixture, test_name) -> 使用测试夹具进行资源类固定化，可将资源用于多个测试案例中

PS : test_fixture是一个test fixture class，是继承testing::Test的一个类，按照官方示例如下

class FooTest : public testing::Test {
    protected:
     virtual void SetUp() { b_.AddElement(3); }

     Foo a_;
     Foo b_;
   };

   TEST_F(FooTest, InitializesCorrectly) {
     EXPECT_TRUE(a_.StatusIsOK());
  }

  TEST_F(FooTest, ReturnsElementCountCorrectly) {
    EXPECT_EQ(a_.size(), 0);
     EXPECT_EQ(b_.size(), 1);
   }

下面简单写下测试案例

1 // 资源固定化
 2 class ReadDicom :public::testing::Test
 3 {
 4 protected:
 5     virtual void SetUp()
 6     {
 7         ct_infilepath = gettestfile("ct.dcm");

60     ASSERT_TRUE(dicom1.WriteDicomInfo(st_outfilepath)) << dicom1.get_lasterror();
