我想编写一个shell脚本，它将只编译和执行我的项目中的单元测试二进制文件。与单元测试相关的Makefile(由CMake生成)中的所有目标都以UnitTest开头，例如UnitTestArray。我如何在shell脚本中编写for循环来单独编译所有单元测试二进制文件?我知道如何在循环中依次运行预编译的二进制文件。这只是我不确定的编译部分。请看下面的shell脚本。
WORKDIR=$PWD
BUILD=~/Dropbox/Projects/Apeiron/build
BIN=$BUILD/bin
# Compile test binaries
cd $BUILD
for target in [UnitTest* in Makefile] # I'm not sure how to write this for loop.
do
echo ""
echo "Compiling $target"
make -j 8 $target
done
# Run tests
cd $BIN
for test in UnitTest*
do
echo ""
echo "Running $test"
./$test
done
cd $WORKDIR
#=============================================================================
# Target rules for targets named UnitTestApeiron
# Build rule for target.
UnitTestApeiron: cmake_check_build_system
$(MAKE) $(MAKESILENT) -f CMakeFiles/Makefile2 UnitTestApeiron
.PHONY : UnitTestApeiron
# fast build rule for target.
UnitTestApeiron/fast:
$(MAKE) $(MAKESILENT) -f CMakeFiles/UnitTestApeiron.dir/build.make CMakeFiles/UnitTestApeiron.dir/build
.PHONY : UnitTestApeiron/fast
#=============================================================================
# Target rules for targets named UnitTestArray
# Build rule for target.
UnitTestArray: cmake_check_build_system
$(MAKE) $(MAKESILENT) -f CMakeFiles/Makefile2 UnitTestArray
.PHONY : UnitTestArray
# fast build rule for target.
UnitTestArray/fast:
$(MAKE) $(MAKESILENT) -f CMakeFiles/UnitTestArray.dir/build.make CMakeFiles/UnitTestArray.dir/build
.PHONY : UnitTestArray/fast
我采用了@MadScientist和@Saboteur用户在上述评论中建议的解决方案。以下是使用@Saboteur的解决方案修改我的shell脚本:
WORKDIR=$PWD
BUILD=~/Dropbox/Projects/Apeiron/build
BIN=$BUILD/bin
# Compile test binaries
cd $BUILD
declare -a TargetList=$(grep "cmake_check_build_system" $BUILD/Makefile|cut -d":" -f1)
for target in ${TargetList[@]}; do
# Check if target keyword contains the substring "UnitTest"
if grep -q "UnitTest" <<< "$target"; then
printf "nCompiling $targetn"
make -j 16 $target
fi
done
# Run tests
cd $BIN
for test in UnitTest*
do
printf "nRunning $testn"
./$test
done
cd $WORKDIR
这会产生以下输出:
$ ./unit_test.sh

我可以看到@MadScientist的建议使用CTest是非常有用的，当gtest单元测试的数量相当大。这是因为CTest提供了通过/失败测试的简明摘要。我必须配置我的项目CMakeLists.txt如下:
enable_testing()
# Fetch GoogleTest directories
include(FetchContent)
FetchContent_Declare(GoogleTest URL https://github.com/google/googletest/archive/609281088cfefc76f9d0ce82e1ff6c30cc3591e5.zip)
FetchContent_MakeAvailable(GoogleTest)
# Add unit test executables
add_executable(UnitTestApeiron ${PROJECT_SOURCE_DIR}/test/UnitTestApeiron.cpp)
add_executable(UnitTestArray ${PROJECT_SOURCE_DIR}/libs/DataContainers/test/UnitTestArray.cpp)
# Link with gtest, gtest_main, and associated libraries.
target_link_libraries(UnitTestApeiron gtest gtest_main)
target_link_libraries(UnitTestArray gtest gtest_main)
add_test(UnitTestApeiron ${BIN_DIRECTORY}/UnitTestApeiron)
add_test(UnitTestArray ${BIN_DIRECTORY}/UnitTestArray)
然后，简单地在项目构建目录中运行ctest得到:
$ ctest
Test project /home/niran90/Dropbox/Projects/Apeiron/build

100% tests passed, 0 tests failed out of 2
