使用CMake，如何从CTest获得详细输出？

问题描述

我正在使用CMake构建项目。我添加了一个使用Boost单元测试框架的单元测试二进制文件。这个二进制文件包含所有单元测试。我已经添加了要由CTest运行的二进制文件：

I'm using CMake to build my project. I have added a unit test binary which is using the Boost unit testing framework. This one binary contains all of the unit tests. I've added that binary to be run by CTest:

ADD_EXECUTABLE( tftest test-main.cpp )
ENABLE_TESTING()
ADD_TEST( UnitTests tftest)

但是Visual Studio中的生成输出仅显示运行CTest的结果：

But the build output in Visual Studio only shows the result of running CTest:

      Start 1: UnitTests
  1/1 Test #1: UnitTests ................***Failed    0.05 sec

  0% tests passed, 1 tests failed out of 1

这不是很有帮助，因为我看不到哪个测试失败。如果我使用-verbose 从命令行手动运行ctest，我将获得Boost单元测试的输出，该输出将告诉您实际失败的原因：

This is not very helpful, because I can't see which test failed. If I run ctest manually from the command line with --verbose I get the output from a Boost unit test which tells what actually failed:

1: Test command: tftest.exe
1: Test timeout computed to be: 9.99988e+006
1: Running 4 test cases...
1: test-main.cpp(20): error in "sanity_check3": check 1 == 2 failed
1:
1: *** 1 failure detected in test suite "Master Test Suite"
1/1 Test #1: UnitTests ................***Failed    0.00 sec

所以，我需要在CMakeLists.txt中进行什么更改，以使CTest以-详细

So, what do I need to change in the CMakeLists.txt to have CTest run with --verbose at all times? Is there a better way to use Boost unit tests with CMake/CTest?

推荐答案

您可以设置环境变量，它将在测试失败时向您显示测试程序的任何输出。使用Makefile和命令行时，执行此操作的一种方法如下：

You can set the environment variable CTEST_OUTPUT_ON_FAILURE, which will show you any output from the test program whenever the test fails. One way to do this when using Makefiles and the command line would be as follows:

env CTEST_OUTPUT_ON_FAILURE=1 make check
