Question

我一直在寻找解决方案，但似乎无法找出发生这种情况的原因。我将CMake用于一个小项目，我想添加单元测试cmakes add_test。它在测试通过时运行良好，但是当它们失败时，我得到一条奇怪的错误消息，我无法解释。

我做了一个很小的例子来说明会发生什么。

的CMakeLists.txt

cmake_minimum_required (VERSION 2.6)

project (TestExample)

enable_testing()

add_executable(succeedExample succeed.cpp)
add_executable(failExample fail.cpp)

add_test(NAME succeedTest COMMAND succeedExample)
add_test(NAME failTest COMMAND failExample)

succeed.cpp

int main()
{
    return 0;
}

fail.cpp

int main()
{
    return 1;
}

我使用Visual Studio 2015，在构建 RUN_TESTS 目标时，出现以下错误：

Severity    Code    Description Project File    Line    Suppression State
Error   MSB3073 The command "setlocal
"C:\Program Files (x86)\CMake\bin\ctest.exe" --force-new-ctest-process -C Debug
if %errorlevel% neq 0 goto :cmEnd
:cmEnd
endlocal & call :cmErrorLevel %errorlevel% & goto :cmDone
:cmErrorLevel
exit /b %1
:cmDone

:VCEnd" exited with code 8. RUN_TESTS   C:\Program Files (x86)\MSBuild\Microsoft.Cpp\v4.0\V140\Microsoft.CppCommon.targets  133

然而，如果我将fail.cpp更改为return 0;我

1>------ Build started: Project: RUN_TESTS, Configuration: Debug Win32 ------
1>  Test project C:/Users/.../projects/cmaketestexample/build
1>      Start 1: succeedTest
1>  1/2 Test #1: succeedTest ......................   Passed    0.01 sec
1>      Start 2: failTest
1>  2/2 Test #2: failTest .........................   Passed    0.02 sec

1>  100% tests passed, 0 tests failed out of 2
1>
1>  Total Test time (real) =   0.03 sec
========== Build: 1 succeeded, 0 failed, 1 up-to-date, 0 skipped ==========

有人能指出我解决这个问题的解决方案吗？我错过了一些明显的东西吗？

谢谢：）

修改

Visual Studio版本是14.0（Visual Studio 2015社区）

Cmake 3.5.2 - 但我在CMakeLists.txt中将版本设置为2.6。

EDIT2

在命令行上运行ctest -C Debug：

Test project C:/Users/.../projects/cmaketestexample/build
    Start 1: succeedTest
1/2 Test #1: succeedTest ......................   Passed    0.02 sec
    Start 2: failTest
2/2 Test #2: failTest .........................***Failed    0.02 sec

50% tests passed, 1 tests failed out of 2

Total Test time (real) =   0.07 sec

The following tests FAILED:
          2 - failTest (Failed)
Errors while running CTest

将fail.cpp更改为

#include <iostream>
int main()
{
    std::cout << "Does it work now?" << std::endl;
    return 1;
}

没有区别。

EDIT3

在Ubuntu 14.04.4 LTS上发生类似的错误使用

cmake version 3.2.2
GNU Make 3.81
g ++（Ubuntu 4.8.4-2ubuntu1~14.04.3）4.8.4

我已经尝试过代码，你看到的是CMake嵌入ctest调用的小脚本。并且ctest确实失败 - 返回非零值 - 如果它正在执行的任何测试失败。 ctest的这种行为是为了在遇到错误时停止运行测试的任何脚本/构建。

ctest // provide some more detailed info on the return code for ctest enum { UPDATE_ERRORS = 0x01, CONFIGURE_ERRORS = 0x02, BUILD_ERRORS = 0x04, TEST_ERRORS = 0x08, MEMORY_ERRORS = 0x10, COVERAGE_ERRORS = 0x20, SUBMIT_ERRORS = 0x40 };可能是以下各项的组合：

所以我看到以下选项：

忽略这个奇怪的错误，您要查找的输出正好在错误消息之上：
```
ctest
```
在没有脚本的情况下在VS上添加您自己的自定义目标，调用if (CMAKE_CONFIGURATION_TYPES) add_custom_target( RUN_CTEST COMMAND ${CMAKE_CTEST_COMMAND} -C $<CONFIGURATION> --force-new-ctest-process WORKING_DIRECTORY "${CMAKE_BINARY_DIR}" ) endif()，只会出现一个错误：
```
ctest
```
添加您自己的自定义目标命令，通过将{{1}}调用移动到单独的脚本中来忽略返回值（请参阅参考资料）。
