Unit testing ctest在实际失败时不报告失败的测试

我有一个单元测试代码，我使用googletest，并使用cmake添加ctest。编译代码后，我可以运行

ctest

或

maketest

来检查所有测试是否通过

Test project /sciclone/home00/hshi/AFQMCLIB/build
      Start  1: mpiTest
1/10 Test  #1: mpiTest ..........................   Passed    0.05 sec

     Start 10: lanczosTest
10/10 Test #10: lanczosTest ......................   Passed    0.05 sec

100% tests passed, 0 tests failed out of 10

Total Test time (real) =   0.80 sec

而如果我单独运行第5个测试，我会得到：

...

如果我运行

ctest--verbose

，我可以看到失败的信息。而如果运行

ctest

，则不会出现错误

我正在使用cmake/3.2.3和google test编写我的单元测试，所有测试都在运行：

add_test( NAME MyTest COMMAND mpirun -np 4 $<TARGET_FILE:MyTest>)

add\u测试（名为MyTest命令mpirun-np4$）

你以前见过类似的问题吗？为什么

ctest

不显示失败错误？

ctest

检查测试的退出状态，以确定测试是通过还是失败。退出状态

0

对应“已通过”。确保测试失败时返回非零值。在这种情况下，您需要让

ctest

对照正则表达式检查测试输出（参见示例）。@Tsyvarev谢谢。我正在使用google测试，我确实在google测试中看到任何退出状态。
