我想撰寫一個 shell 腳本，它只會在我的專案中編譯和執行單元測驗二進制檔案。在所有目標Makefile單元測驗相關聯（由CMake的生成）首先UnitTest，例如UnitTestArray。如何在 shell 腳本中撰寫 for 回圈來單獨編譯所有單元測驗二進制檔案？我知道如何在回圈中順序運行預編譯的二進制檔案。這只是我不確定的編譯部分。請參閱下面的我的 shell 腳本。
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
以下是生成的 Makefile 中的一些示例目標規則：
#=============================================================================
# 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

我采用了用戶@MadScientist 和@Saboteur 在上述評論中建議的解決方案。以下是使用@Saboteur的解決方案修改我的shell腳本：
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 $target\n"
make -j 16 $target
fi
done
# Run tests
cd $BIN
for test in UnitTest*
do
printf "\nRunning $test\n"
./$test
done
cd $WORKDIR
這會產生以下輸出：
$ ./unit_test.sh

我可以看到@MadScientist 的建議在gtest單元測驗數量非常大時使用 CTest 非常有用。這是因為 CTest 提供了通過/失敗測驗的簡明摘要。我必須按如下方式配置我的專案 CMakeLists.txt：
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，只需ctest在專案構建目錄中運行即可：
$ ctest
Test project /home/niran90/Dropbox/Projects/Apeiron/build
Start 1: UnitTestApeiron
1/2 Test #1: UnitTestApeiron .................. Passed 0.01 sec
Start 2: UnitTestArray
2/2 Test #2: UnitTestArray .................... Passed 0.00 sec
100% tests passed, 0 tests failed out of 2
Total Test time (real) = 0.01 sec
