捕获库(单元测试)和CTest(CMake)集成 [英] Catch lib (unit testing) and CTest (CMake) integration

问题描述

我正在寻找Catch CatchLib 与CMake测试(Ctest)集成的成功示例.据我了解，这是必须解析应用程序输出的其他cmake脚本? 有人写过这个吗?大概分享了这个吗?

I'm looking for successful example of Catch CatchLib integration with CMake test (Ctest) . as I understand this is additional cmake script which has to parse application ouput? Did someone already written this? probably shared this?

我已将 cmake脚本提交给CatchLib与CTest集成的Catch.这是Fraser99的cmake脚本的简化版本，此处

I've committed cmake script to CatchLib , for the integration Catch with CTest. this is a simplified version of Fraser99's cmake script here

推荐答案

将Catch与CMake集成非常简单，因为它是仅标头的库.

Integrating Catch with CMake is rather simple, as it's a header-only library.

以下是您要做的事情的简要介绍:

Here's a quick rundown of what you have to do:

您可以假定Catch源已经安装在构建计算机上，或者使用

You can either assume that the Catch sources are already installed on the build machine or use ExternalProject for fetching them as part of the build process.

在任何一种情况下，您最终都会在构建计算机上某个已知目录中获得Catch头文件.我建议创建一个接口目标，以使测试可执行文件了解此信息:

In either case, you will end up with the Catch header files in some known directory on your build machine. I would recommend creating an interface target for making this information known to your test executables:

add_library(Catch INTERFACE)
target_include_directories(Catch INTERFACE ${YOUR_CATCH_INCLUDE_DIR})

这样，您可以简单地将Catch指定为target_link_libraries的依赖项:

That way, you can simply specify Catch as a dependency to target_link_libraries:

add_executable(my_test ${MY_TEST_SOURCES})
target_link_libraries(my_test PUBLIC Catch)

与CMake一样， add_test 小心地将测试引入CTest:

As usual with CMake, add_test takes care of introducing the tests to CTest:

enable_testing()
add_test(NAME MyAwesomeTest COMMAND my_test)

仅此而已.在已构建的项目上运行make test来运行测试.

And that's it already. Run make test on the built project to run your tests.

我在Github上有一个项目，如果您这样做，需要查看完整的工作示例.

I have a project on Github that does this if you need to see a complete working example.

更新以获取较新版本的Catch::如果您已经升级到Catch2，则该文件将带有其自己的软件包配置文件，因此您可以调用整体上更平滑的CMake集成，不必开始定义自己的接口目标.尽管上面的方法即使在Catch2上仍然可以使用，但如果您的Catch版本已经支持find_package，我建议您使用find_package.

Update for newer versions of Catch: If you've already upgraded to Catch2, that one comes with its own package config file so you can just integrate it calling find_package. This provides a smoother CMake integration overall and you don't have to start defining your own interface target. While the approach above will still work even with Catch2, I would recommend using find_package if your Catch version supports it already.
