C++ 在 Eclipse 中使用 googletest：如何？

Question

提问by user478310

I've downloaded google test, but now I've no idea on how to link it to my project in eclipse. Should I add it as a source folder? Should include it as g++ included library? And how can I run test then?

我已经下载了 google test，但现在我不知道如何将它链接到我在 eclipse 中的项目。我应该将它添加为源文件夹吗？应该将它包含为 g++ 包含的库吗？那么我该如何运行测试呢？

Using Riga's excellent answer, here is a summary of how I got it to work:

使用里加的优秀答案，这里是我如何让它工作的总结：

Created a new C++ project in Eclipse (I chose Executable > Empty Project)
Downloaded googletest 1.5.0, untarred, and ran ./scripts/fuse_gtest_files.py . <project-dir>/contrib
Back in Eclipse, excluded the contribdirectory from the Release build configuration, and added <project-dir>/contribto the include directories (odd, I know)
Added a srcdirectory and added a class named Foo(see below for the contents of Foo.h--I left Foo.cppempty for now)
Added a testdirectory in Eclipse, excluded it from the Release build configuration, added <project-dir>/contribto the include directories, and added new source files FooTest.cppand AllTests.cpp(see below for contents)
Built and ran the project!

在 Eclipse 中创建了一个新的 C++ 项目（我选择了 Executable > Empty Project）
下载googletest 1.5.0，解压，然后运行./scripts/fuse_gtest_files.py . <project-dir>/contrib
回到 Eclipse，contrib从 Release 构建配置中排除该目录，并添加<project-dir>/contrib到包含目录中（奇怪，我知道）
添加了一个src目录并添加了一个名为的类Foo（请参阅下面的内容Foo.h--我暂时Foo.cpp留空）
test在 Eclipse 中添加了一个目录，将其从发布构建配置中排除，添加<project-dir>/contrib到包含目录中，并添加了新的源文件FooTest.cpp和AllTests.cpp（内容见下文）
构建并运行项目！

Foo.h:

福.h：

#ifndef FOO_H_
#define FOO_H_
class Foo {
public:
  virtual ~Foo();
  Foo();
  bool foo(void) { return true; }
};
#endif /* FOO_H_ */

FooTest.cpp:

FooTest.cpp：

#include "gtest/gtest.h"
#include "Foo.h"
namespace {
  class FooTest : public ::testing::Test {
  protected:
    Foo foo;
  };
  TEST_F(FooTest, Foo) {
    ASSERT_TRUE(foo.foo());
  }
}

AllTests.cpp:

AllTests.cpp：

#include "gtest/gtest.h"
#include "FooTest.cpp"
int main(int argc, char **argv) {
  ::testing::InitGoogleTest(&argc, argv);
  return RUN_ALL_TESTS();
}

Here are the detailed steps:

以下是详细步骤：

In Eclipse, open the Filemenu and select New> C++ Project

通过右键单击 src 文件夹并选择 New->Source File 添加一个源文件。将此文件称为 Counter.cpp。
添加另一个源文件并将其命名为 Counter_Tests.cpp。

Copy and paste the code below into the appropriate files:

将下面的代码复制并粘贴到相应的文件中：

Counter.h

计数器.h

class Counter { 
private: 
      int mCounter;
public:    
      Counter() : mCounter(0) {}  
      int Increment();    
};

Counter.cpp

计数器.cpp

#include <stdio.h>
#include "Counter.h"

int Counter::Increment() {    
      return mCounter++;
}

Counter_Tests.cpp

#include "gtest/gtest.h"
#include "Counter.h"

TEST(Counter, Increment) {
      Counter c;    
      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();
}

In the Project menu select Build All. Now, to connect up the GoogleTest unit testing framework, select Run Configurations from the Run menu. From this dialog, select C/C++ Unit and click the New button.

在项目菜单中选择全部构建。现在，要连接 GoogleTest 单元测试框架，请从“运行”菜单中选择“运行配置”。从该对话框中，选择 C/C++ 单元并单击新建按钮。

You should not add it to your source folder, make separate folder instead. This is for avoidance of dependency of your production code from testing project. Do it like this

您不应将其添加到源文件夹中，而应创建单独的文件夹。这是为了避免您的生产代码依赖于测试项目。像这样做

../ #your project folder
Makefile
src/
  module1 #some module
  module2 #another module
build #tmp for build
dist #binaries 
contrib/
  gtest
  ...
test/ #your test project folder
  Makefile
  src/
    module1 #correspondent to main project's one
    module2 #correspondent to main project's one
  build
  dist
  ...

I usually use google test as two files, this is very handy. Use scripts/fuse_gtest_files.pyfrom gtest distribution to extract them. Having only two files you can include their compilation in your test project compilation and have simple project structure.

我通常使用 google test 作为两个文件，这很方便。使用scripts/fuse_gtest_files.pyfrom gtest 分布来提取它们。只有两个文件，您可以将它们的编译包含在您的测试项目编译中，并具有简单的项目结构。

In your test projectspecify include directories ../contrib:../src:src. Thus you can include headers like this

在您的测试项目中指定包含目录../contrib:../src:src。因此，您可以包含这样的标题

test/src/module1/class1Test.h:

测试/src/module1/class1Test.h：

#include "gtest/gtest.h"
#include "module1/class1.h"

// test class1 here
// ...

test/src/mainTest.cpp:

测试/src/mainTest.cpp：

#include "gtest/gtest.h"
#include "module1/class1Test.h"
#include "module2/class2Test.h"
// include other tests you have
// ...

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

Here is my solution for Eclipse 4.3 and CDT 8.2 I felt this was somewhat easier then described above.

这是我针对 Eclipse 4.3 和 CDT 8.2 的解决方案，我觉得这比上面描述的要容易一些。

Download gtest and install it as described in the readme.txt (using cmake and make in linux)
Go to "YourProject-> Properties-> C/C++ Build-> Settings-> GCC C++ Compiler-> Includes-> Include paths" and add the include folder in gtest
Go to "YourProject-> Properties-> C/C++ Build-> Settings-> GCC C++ Linker-> Libraries", add the gtest folder as search path and add libraries "gtest" and "pthread"

下载 gtest 并按照 readme.txt 中的描述进行安装（在 linux 中使用 cmake 和 make）
转到“YourProject-> Properties-> C/C++ Build-> Settings-> GCC C++ Compiler-> Includes-> Include paths”并在gtest中添加include文件夹
转到“YourProject-> Properties-> C/C++ Build-> Settings-> GCC C++ Linker-> Libraries”，添加gtest文件夹作为搜索路径并添加库“gtest”和“pthread”

(4. If you have tests in the same project as sources exclude tests from release build)

(4.如果你在同一个项目中有测试作为源排除发布版本中的测试)

Go to "Run-> Run Configurations..." and Create a new C/C++ Unit run configuration
Set project to your project and C/C++ Application to your Application in main tab. Set Tests Runner to Google Test Runner in C/C++ Testing tab.

转到“运行-> 运行配置...”并创建一个新的 C/C++ 单元运行配置
在主选项卡中将项目设置为您的项目并将 C/C++ 应用程序设置为您的应用程序。在 C/C++ 测试选项卡中将测试运行程序设置为 Google 测试运行程序。

(7. Error notifications may stick around in the eclipse gui, if this is the case re-indexing the project might help)

（7. eclipse gui 中可能会出现错误通知，如果是这种情况，重新索引项目可能会有所帮助）

I've tray your solution and it runs well. I can say that for compile gtest is not very clear in the README. txt.

我已经提供了您的解决方案，并且运行良好。我可以说对于编译 gtest 在 README 中不是很清楚。文本。

I've run the makefile in the /make directory through a cygwin console. In my case the compiler advise me that don't findt the pthread library. So I modified the line

我已经通过 cygwin 控制台运行了 /make 目录中的 makefile。就我而言，编译器建议我不要找到 pthread 库。所以我修改了这条线

CXXFLAGS += -g -Wall -Wextra -pthread

and changed it to

并将其更改为

CXXFLAGS += -g -Wall -Wextra -lpthread

The output I get is gtest_main.a. Then I have rename this file into libgtest.a and copy it to C:\cygwin\lib directory.

我得到的输出是gtest_main.a. 然后我将此文件重命名为 libgtest.a 并将其复制到C:\cygwin\lib directory.

Then i've configure my eclipse project to use cygwin and added gtest and pthread as you say... and it works!

然后我将我的 eclipse 项目配置为使用 cygwin 并按照您的说法添加了 gtest 和 pthread ......并且它有效！
