[英]using googletest in eclipse: how?
I've downloaded google test, but now I've no idea on how to link it to my project in eclipse.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。 Should I add it as a source folder?
我应该将它添加为源文件夹吗? Should include it as g++ included library?
应该将它包含为 g++ 包含的库吗? And how can I run test then?
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:
./scripts/fuse_gtest_files.py . <project-dir>/contrib
./scripts/fuse_gtest_files.py . <project-dir>/contrib
./scripts/fuse_gtest_files.py . <project-dir>/contrib
contrib
directory from the Release build configuration, and added <project-dir>/contrib
to the include directories (odd, I know)contrib
目录,并将<project-dir>/contrib
到包含目录(奇怪,我知道)src
directory and added a class named Foo
(see below for the contents of Foo.h
--I left Foo.cpp
empty for now)src
目录并添加了一个名为Foo
的类( Foo.h
的内容见下文——我Foo.cpp
留空)test
directory in Eclipse, excluded it from the Release build configuration, added <project-dir>/contrib
to the include directories, and added new source files FooTest.cpp
and AllTests.cpp
(see below for contents)test
目录,将其从发布构建配置中排除,将<project-dir>/contrib
到包含目录,并添加了新的源文件FooTest.cpp
和AllTests.cpp
(内容见下文) 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"

运行后,按默认值单击 Next,直到进入 Select Packages 窗口。
You will need to search for and install two packages: gcc and make.您将需要搜索并安装两个软件包:gcc 和 make。
The first search term is gcc.第一个搜索词是 gcc。 Search for gcc and then open the Devel folder.
搜索 gcc,然后打开 Devel 文件夹。 Mark the following packages for install by clicking on the word Skip (it will then change to the build number, which may by higher than the one depicted here): gcc-core, gcc-g++, and libgcc1.
通过单击“跳过”一词标记以下要安装的软件包(然后它会更改为内部版本号,可能比此处描述的要高):gcc-core、gcc-g++ 和 libgcc1。
The second search term is make.第二个搜索词是 make。 Here, we will only need the Devel package make.
在这里,我们只需要 Devel 包 make。
Once these have been selected, click Next to install.选择这些后,单击下一步进行安装。
Step 3 Download and build Google Test project步骤 3 下载并构建 Google Test 项目
Download the latest release of GoogleTest from https://code.google.com/p/googletest/downloads/list , and extract the zip file contents into a common directory.从https://code.google.com/p/googletest/downloads/list下载最新版本的 GoogleTest,并将 zip 文件内容解压到一个公共目录中。 It is important that all users are able to access this directory.
重要的是所有用户都能够访问此目录。
(Note: the following commands use make
-- the last revision of GoogleTest that uses make
ishttps://github.com/google/googletest/releases/tag/release-1.8.1 . For future revisions of GoogleTest use cmake
instead.) (注:以下命令使用
make
- GoogleTest的最后一个版本,它使用make
是https://github.com/google/googletest/releases/tag/release-1.8.1对于GoogleTest使用的未来版本。 cmake
来代替。 )
To build the Google Test project:要构建 Google 测试项目:
cd c:/<<yourpath>>/gtest-1.7.0/make/
cd c:/<<yourpath>>/gtest-1.7.0/make/
make
make
ar -rv libgtest.a gtest-all.o
ar -rv libgtest.a gtest-all.o
Step 4 Add the Cygwin bin directory to the computers PATH variable步骤 4 将 Cygwin bin 目录添加到计算机的 PATH 变量中
Follow the instructions on this page for your version of Windows: http://www.java.com/en/download/help/path.xml , to add Cygwins bin directory to the computers PATH environment variable.按照此页面上适用于您的 Windows 版本的说明进行操作: http : //www.java.com/en/download/help/path.xml ,将 Cygwins bin 目录添加到计算机的 PATH 环境变量中。 (typically by adding ;C:\\cygwin64\\bin to the end of the current value).
(通常通过将 ;C:\\cygwin64\\bin 添加到当前值的末尾)。
Step 5 Create a new project that uses GoogleTest步骤 5 创建一个使用 GoogleTest 的新项目
Start Eclipse and select File->New->C++ Project.启动 Eclipse 并选择 File->New->C++ Project。 Enter the values below and click Finish.
输入以下值并单击完成。
In the Project Explore, right-click the name of the project and select Properties.在 Project Explorer 中,右键单击项目名称并选择 Properties。 Under C/C++ Build, change the Builder type to Internal Builder.
在 C/C++ Build 下,将 Builder 类型更改为 Internal Builder。
Under C/C++ Build, select Settings, then click on the Includes folder under Cygwin C++ Compiler.在 C/C++ Build 下,选择 Settings,然后单击 Cygwin C++ Compiler 下的 Includes 文件夹。 Click on the Add button in the top box and then browse to the GoogleTest include folder.
单击顶部框中的添加按钮,然后浏览到 GoogleTest 包含文件夹。
Lastly, under the Cygwin C++ Linker folder, select Miscellaneous and then click the Add icon under Other objects.最后,在 Cygwin C++ Linker 文件夹下,选择 Miscellaneous,然后单击 Other objects 下的 Add 图标。 Find the libgtest.a file that you built back in step 3 (it should be in the make directory of the unzipped gtest folder).
找到您在第 3 步中重新构建的 libgtest.a 文件(它应该位于解压缩的 gtest 文件夹的 make 目录中)。
Thats it!就是这样! Now you're ready to try it out.
现在您可以尝试一下了。
Step 6 Write some code that uses GoogleTest步骤 6 编写一些使用 GoogleTest 的代码
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 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.在项目菜单中选择全部构建。 Now, to connect up the GoogleTest unit testing framework, select Run Configurations from the Run menu.
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”。 From this dialog, select C/C++ Unit and click the New button.
从该对话框中,选择 C/C++ 单元并单击新建按钮。
It should fill in this project name automatically under C/C++ Application, if not click on Search Project to select this project.在C/C++ Application下应该自动填写这个项目名称,如果没有点击Search Project选择这个项目。 Next, click on the C/C++ Testing tab.
接下来,单击 C/C++ 测试选项卡。 In the Tests Runner drop-down, choose Google Tests Runner, and then click Run to watch the magic!
在 Tests Runner 下拉列表中,选择 Google Tests Runner,然后单击 Run 观看魔术!
Below is a snapshot of the result.下面是结果的快照。 After writing more code/tests, you can click on the button highlighted in red to quickly recompile and re-run all of the tests.
编写更多代码/测试后,您可以单击以红色突出显示的按钮以快速重新编译并重新运行所有测试。
You should not add it to your source folder, make separate folder instead.您不应将其添加到源文件夹中,而应创建单独的文件夹。 This is for avoidance of dependency of your production code from testing project.
这是为了避免您的生产代码依赖于测试项目。 Do it like this
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.我通常使用 google test 作为两个文件,这很方便。 Use
scripts/fuse_gtest_files.py
from gtest distribution to extract them.使用 gtest 发行版中的
scripts/fuse_gtest_files.py
来提取它们。 Having only two files you can include their compilation in your test project compilation and have simple project structure.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
.在您的测试项目中指定包含目录
../contrib:../src:src
。 Thus you can include headers like this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)下载 gtest 并按照 readme.txt 中的描述进行安装(在 linux 中使用 cmake 和 make)
Go to "YourProject-> Properties-> C/C++ Build-> Settings-> GCC C++ Compiler-> Includes-> Include paths" and add the include folder in gtest转到“YourProject-> Properties-> C/C++ Build-> Settings-> GCC C++ Compiler-> Includes-> Include paths”并在gtest中添加include文件夹
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"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转到“运行-> 运行配置...”并创建一个新的 C/C++ 单元运行配置
Set project to your project and C/C++ Application to your Application in main tab.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。 Set Tests Runner to Google Test Runner in C/C++ Testing tab.
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.我已经提供了您的解决方案,并且运行良好。 I can say that for compile gtest is not very clear in the README.
我可以说对于编译 gtest 在 README 中不是很清楚。 txt.
文本。
I've run the makefile in the /make directory through a cygwin console.我已经通过 cygwin 控制台运行了 /make 目录中的 makefile。 In my case the compiler advise me that don't findt the pthread library.
就我而言,编译器建议我不要找到 pthread 库。 So I modified the line
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
.我得到的输出是
gtest_main.a
。 Then I have rename this file into libgtest.a and copy it to C:\\cygwin\\lib directory
.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!
I hope it can help someone我希望它可以帮助某人
