'"No tests were found!!! " in cmake tutorial step 4
The contens of CMakeLists.txt:
cmake_minimum_required(VERSION 3.10)
# set the project name and version
project(Tutorial VERSION 1.0)
# specify the C++ standard
set(CMAKE_CXX_STANDARD 11)
set(CMAKE_CXX_STANDARD_REQUIRED True)
# should we use our own math functions
option(USE_MYMATH "Use tutorial provided math implementation" ON)
# configure a header file to pass some of the CMake settings
# to the source code
configure_file(TutorialConfig.h.in TutorialConfig.h)
# add the MathFunctions library
if(USE_MYMATH)
add_subdirectory(MathFunctions)
list(APPEND EXTRA_LIBS MathFunctions)
endif()
# add the executable
add_executable(Tutorial tutorial.cxx)
target_link_libraries(Tutorial PUBLIC ${EXTRA_LIBS})
# add the binary tree to the search path for include files
# so that we will find TutorialConfig.h
target_include_directories(Tutorial PUBLIC
"${PROJECT_BINARY_DIR}"
)
install(TARGETS Tutorial DESTINATION bin)
install(FILES "${PROJECT_BINARY_DIR}/TutorialConfig.h"
DESTINATION include
)
enable_testing()
# does the application run
add_test(NAME Runs COMMAND Tutorial 25)
# does the usage message work?
add_test(NAME Usage COMMAND Tutorial)
set_tests_properties(Usage
PROPERTIES PASS_REGULAR_EXPRESSION "Usage:.*number"
)
# define a function to simplify adding tests
function(do_test target arg result)
add_test(NAME Comp${arg} COMMAND ${target} ${arg})
set_tests_properties(Comp${arg}
PROPERTIES PASS_REGULAR_EXPRESSION ${result}
)
endfunction()
# do a bunch of result based tests
do_test(Tutorial 4 "4 is 2")
do_test(Tutorial 9 "9 is 3")
do_test(Tutorial 5 "5 is 2.236")
do_test(Tutorial 7 "7 is 2.645")
do_test(Tutorial 25 "25 is 5")
do_test(Tutorial -25 "-25 is (-nan|nan|0)")
do_test(Tutorial 0.0001 "0.0001 is 0.01")
Rebuild the application and then cd to the binary directory and run the ctest executable:
ctest -N
andctest -VV
. For multi-config generators (e.g. Visual Studio), the configuration type must be specified with the-C <mode>
flag. For example, to run tests in Debug mode usectest -C Debug -VV
from the binary directory (not the Debug subdirectory!). Release mode would be executed from the same location but with a-C Release
. Alternatively, build theRUN_TESTS
target from the IDE.
I run the cmake commands like above, but it can not run successfully.
I Rebuild the application and cd to the bin directory, and run
ctest -C Debug -VV
the rusult is
No tests were found!!!
What did I miss?

Should be run from the build directory, it's not clear in the tutorial, but if you go to the documentation you can see it.
